There's a sixth way. If you're using silicone moulds you can warm the mould in the oven before pouring the resin in it. Take the mould out of the oven, let it air for a few seconds and then pour the resin in. The warmth of the mould will get rid of the bubbles in the resin.
@@Chris.Rhodes Silicon can withstand temperatures from way above 200°C without deforming so you could put it in the oven on a high temperature for a short time or on a lower temperature for a bit longer time. I usually put the oven on 175°C and warm the mould for about 15 minutes. Recently I use a large room in the attic for my hobbies and since I don't have an oven upstairs I use a cup warmer to warm the resin. Works just as well. I just plug the little warmer in, when it's hot I put the cup with the resin on it and leave it for about 10 minutes before pouring it slowly into the mould. What also helps is mixing the two parts gently. The harder/wilder you stir, the more bubbles you create.
I have a Dehydrator I use for drying my firework stars and black powder an I stick my silicone mold in it for a good while at 140 degree's to warm them up, I like using it because it's hot air warming it up and not straight up HEAT.
This is the Best Comment Section I've ever visited...I see it as a round table, you guys are just talkin like you've known each other for years. Thanks All you guys!!! Too much fun 🐞
I tried the hacks that didn’t need a gadget and was unsuccessful. However, I accidentally discovered that by warming up part A and Part B in their separate bottles worked like a charm! I was cleaning up my workspace and moved the bottles to the window where the morning sun comes through. When I poured both parts and stirred up, I found my resin to be clearer than ever before
@@anicaica well, I wouldn’t want to use my torch while the epoxy was still in the container, especially if I’m using a medicine type cup as it will melt the plastic cup. Also, even if I use the silicone cup to mix up my epoxy, I could accidentally burn myself or anything near the cup. However, I do use my torch every so often after the epoxy is applied to my tumbler surface instead of a heat gun to pop bubbles. Using the heat gun would move your epoxy around because it blows hot air. If your intent is to move your epoxy to get motion in your design then a heat gun is the way to go. There’s no one way to do things. Continue to browse RUclips for methods that works for you. Good luck
@@Dante190186 I do, I actually just place my closed bottles back in a bowl and fill up with hot tap water, by the time I need it again it’s ready for me. You’ll see the harder will be a lot easier to mix with the resin when warmed up.
My first resin pour was in 1974 omg. BEST way if you make art to sell and need to be very productive: HEAT room to 72 degrees or more, HEAT resin in a warm water bath - I even add my container to water bath, pour in resin on side of container, pour in hardener on side of container, stir slowly in figure 8 scraping sides, bottom, and stir stick for at least 3 minutes, depending on resin brand. Voila!
Also mixing fast will cause bubbles and when pouring your hardener and resin you should pour it against the side of your cup instead of directly in to avoid causing more bubbles.
Aoleon I always get bubbles no matter what. Even after I’ve used a torch or a heat tool to pop them. It looks smooth but when I come back there are more bubbles and things that look like strands of hair but it’s not hair.
Interesting! Though working with larger pieces, I think I’d be concerned that my resin would set faster than I would like it to set. Still, I do believe storing the resin and hardener(prior to mixing) in a warm area could definitely be helpful. The comments on this post were especially helpful. 😊
I always found that a good way to prevent bubbles is to take more care while mixing - mix more slowly and for a longer time - you can achieve equally thorough mixing while introducing almost no air and the overall time you take out of the resin's pot life can be similar as when you mix vigorously and then try to get air bubbles out again.
@@lpmwalker_of_sky1903 I use a long stick of 3mm acrylic, about 15 mm wide. because of the flat edges, it lets me scrape the bottom and the walls of the mixing container. But as Wiliam suggested, something wider at the bottom and with a thinner stem could work well too. But it would have to be a stronger material. Also, having a rectangular mixing stick allows for esier removal of hardened epoxy, so you can reuse it almost indefinitely.
What you say is true for most brands of casting resin. Unfortunately, I discovered that a certain brand is horrible about bubbles - no matter how carefully I stirred the parts together I ended up with so many teeny weeny tiny bubbles that I couldn't see without my glasses. Sadly, because of my laziness about finding my glasses when I was pouring resin to make shot glasses for my friends for Christmas, I didn't see the stupid little bubbles and ruined the gifts I was making. Let me know if you want to know what brand of resin I'm referring to, I'd be happy to tell you in a private message or email.
Storing part "A" and "B" in foam insulation with coaster warmers in both storage chambers makes the resin thinner so it mixes easier and helps it last for up to 7 -12 years of storage. A few bubbles form in the first place when using pre-warmed resins. Polishing the surface with a propane torch is a "MUST-DO" step in any case since pouring creates a few extra bubbles at the edges and corners.
The hair dye gave me the answer I needed cause I was wondering who I would get "flesh" color in my resin and how to get the bubbles out thanks mate ur a life safer🙏🏼❤️
Learned a nice trick - heat. But flame might not always be desirable because the chemicals may be flammable. As a MicroSection Tech, I've made plenty of resins and mounted quite a few specimens. Air bubbles were always an issue. The way I removed bubbles was to incorporate a centrifuge. Would drive resin deep into the mold and molded parts while forcing the air out. And it took typically 2 to 5 minutes, depending on the part being encapsulated. The vacuum chamber - I wouldn't recommend that. I saw outgassing going on in your video. Meaning there was no air bubble but one appeared as the gasses were pulled out of the chemicals. And sometimes that can leave even more bubbles. Oh, and your chamber lid had a crack, which appeared to be worse at the end. Vacuum chambers can be dangerous when they burst. Sure they implode, but that just means high velocity shrapnel flying around and bouncing back up in your face. I would not recommend vacuum.
It depends on the resin used. I've had unpleasant experiences with two resins when placed in water. I actually prefer the heat gun (blower). Thank you for sharing. ♥️👍
Here's one. If you use epoxy with wood, say in a table or jewelry box, you need to paint a layer on the wood first and let it set. UV, regular, doesn't matter except for cure time. Or, you can use shellac first (the clear sanding sealer type). The goal is to coat the wood so it doesn't off-gas. Wood is porous and has trapped air. Wood breathes. You can pour epoxy, flame out the bubbles, and come back well after you can do anything about it to find bubbles. That's the wood off-gassing. Heating the epoxy in this case, no matter the method, won't work. The issue is the wood breathing. Seal your wood, preferably with epoxy, and you won't have a problem. If you also fill any seams with UV resin, you can set it under a strong light or take it outside under a sunny sky for about 30 minutes. That way, when you pour, no leaks either. Never rely on the wood glue in a joint to keep the resin where you want it. You'll be sad.
wow! I use wood all the time and I'm so fristrated because I almost never get a piece with a smooth finish. I put gesso on it... but now maybe I should just do a layer of resin first...
I recently created black resin to coat a guitar using black alcohol ink. Used about 50 drops of ink in a small cup of mix. Yes it made the mix thinner, which was good for my application, but the alcohol made the mix bubble free in the cup before pouring. Worked great.
I put my mixing cup into hot water and mix the resin while the cup is in the hot water. Helps so much! Barely any bubbles. I also mix very slow. Then I hit it with the touch once its applied and it usually get the remaining bubbles out. I use a resin with a 30 min window
Poured resin for the 3rd time today. After my second pour yesterday my resin was filled wit micro bubbles. I put my resin bottles in a warm water bath then when I poured I stir slowly while aiming my heat gun to the resin. Then pour slowly into the mold. Let’s see what the results are when I pop it out tomorrow. I’m learning with each pour trying to not get upset on my 2 fails. Hopefully this 3rd pour will be better. I’m trying to preserve my rare cactus blooms. Learning the art of resin is expensive and strsssful 😅😩🥴🤯
@@Isha_Sethi , it's extremely dangerous. Extremely. Some will tell you otherwise, but by the time they find out they were wrong, it will be too late. Don't get me wrong, resin can be gorgeous and OK if done outside with a respirator and eye protection...and in fairly short sessions. About 10 years ago, I met an artist at a top 5 art show in the U.S. When I asked her about her art, she told me she had already had to give that part up because of the damage it had done to her lungs. She was probably 40-50. Many young people now are just jumping in because no one has told them the dangers or the didn't bother to research. Have fun, but please be careful.
@ilovejewelyn You can't preserve flowers in resin without drying them first is silica beads/sand. If you don't do this, the flowers will decay in the resin and turn black or brown due to the moisture in them.
You guys do know that heating up the activated resin SIGNIFICANTLY accelerates the hardening shortening the working time and depending on you batch size and temperature can auto-ignite.
Hot water made mine so hard lmao it was my first time makin a ashtray. This video caused me my whole cup of this stuff😂😂sit it in hot water my butt lol
I was gonna say 3 and 5, 3 is much cheaper and only a few minutes wait. You can also heat the molds to 150F or so (Check the temp limits on your mold silicone) then pour the resin in and the bubbles disappear as you are pouring. It works really well just make sure of the heat toleration's of the material you plan to use first. 3 has been a go to for me since they came out and a usb humb can make it easy to have multiple colors going at once for whatever you may need.
I’ve been doing the hot water method since I first started resin. I researched resin and everything for months before ever trying to use it and that was my very first way and my only way beside the lighter at the end for the few minor air bubbles I get when it’s poured into the mold
@@chamathfonseka7529 Not sure to whom your query was directed, but for me personally, I like Stone Coat and Faux Rizzle the best. This is something that you'll have to explore for yourself though and figure out what works best for your particular style of art. For instance, I absolutely hate "Art Resin" and multitudes of others love the stuff. I find it fragile, soft and intolerant to polishing out defects. My only real advice is to buy the smallest quantity that a company sells, and see how you like it and do that with several companies before you decide who will be your go to supplier. Resin is absurdly expensive and you don't want to get stuck with 2 gallons of stuff you don't like and hundreds of dollars wasted. Best of luck to you. 🙏
And a mask! Even if the resin states it’s non-toxic you should always wear PPE with a proper filtering mask. Resin toxicity is a real risk and can cause severe damage. Please be careful.
And I just spent around $200 for a good pressure pot! I like the heated coaster method and I'm going to try it, mostly for the ease and simplicity. A vacuum chamber can be extremely messy! You have to sit and watch it, controlling the amount of vacuum, or the resin will turn to foam and spill all over the inside, as it did a little in this video. UPDATE: I used the heated coaster for a while, and it has ruined all of my silicone cups - the bottoms eventually became brittle and the resin wouldn't clean up after it dried. I now use the hot water method, before putting the mold in my pressure pot. I also got a vacuum chamber, which I will use for silicone to make molds with.
The trick with forced convection from heat seemed good but I suppose it will accelerate the curing which could be a problem in many cases when the pouring time is critical.
IDK what epoxy he used, but most will start to cure if left alone, mixed for 15 minutes. If you place your measued epoxy in a water bath before you mix you shouldn't get bubbles, if you still get some place it back in the warm water for a few seconds.
Mine doesn't cure if I left alone for 20 mins alone. This isn't that much epoxy to cause big troubles, especially if it is slow curing. Which can handle even 5-6cm depth.
For the water bath method, I usually keep the resin bottles part A & B in a bowl of warm water for a few hours, and the mixture cup in the bowl of warm water also while stirring for at least 3-4 mins.. ++ Avoid lifting the stir stick in and out of the mixture and be very careful not to get water inside your resin cup, I heard it can ruin the mixture completely!
Hi BuzzingFish. Miley's comment aside [though probably true], I want to comment that your video without vocals gave a very visual and informative understanding of how to get the bubbles out of resin. For most enthusiasts and DIY startups like myself, the "pressure pot", though probably the best solution, would be an added investment. Thanks for the insight. Cheers
The pressure pot is good for getting rid of bubbles after pouring the resin. These are good methods to get the bubbles out before the pour, especially if it has a long work time so you don't have to rush before using it. The fewer bubbles during the pour means less bubbles for the pressure pot to squeeze, which can affect the final product as the resin level will go down as the bubbles shrink.
FYI There are two different things being talked about here "Pressure Pot" which adds pressure to the chamber with a compressor and a "vacuum chamber " with a vacuum pump (which was used in the video)
FIRST METHOD! Mix it SLOWLY! It cause less bubble and as time goes your resin will be thicker which is better. Lighter is not recommended it can ruin the molds because it is hotter than those can handle.
@@MovingT5 Apply strips of clear cellotape on the foamboard for easy demolding. Not sure my comment still meets your enquiry but maybe someone else might benefit someday
Works perfect for my UV resin! I just mix in my glitters or coloring, and let it sit on the electric cup heater. Gets rid of the bubbles perfectly and is so much easier to pour! I can get rid of any surface bubbles easily as well with a mini blow torch or heat gun
I tried the warm water method, and although it removes a lot of bubbles, it affects the solidification time enormously. I usually have a dry, solid model in 24 hs. With the warming in warm water it took 5 weeks to get solid! So, it is a no-go.
I use a TON of rubbing alcohol - not necessarily on the resin itself (though there are some methods I would love to try), but as a cleaning agent for most things around my desk. I avoid open flames at all costs. Heat guns are really inexpensive and work great... for regular bubbles. I'm still having problems with microbubbles and am looking at vacuum chambers as we speak.
I am fairly new to resin and mostly use UV resin at this time. I do use a flame to get rid of some of the bubbles in the mold. But I have found a spraying a small amount of alcohol works for me as it evaporates quickly. (I only use the alcohol after using the flame as we all know, alcohol is a flammable.)
Just a heads up. I wasted almost ½ gallon of resin, by putting it in warm water. It pulled bubbles up but hardened before I could mix colors. Warming them separately works a little better.
I think the atmosphere temperature as well as the brand of resin has a lot to do with bubbles appearing. It was so cold here before Christmas, even inside the house... I never thought the temperature of my work space would matter as much as it does.
Tips to avoid bubbles Warm both the hardener and resin in their containers. Pour both of em slowly into the mixing cups Mix gently and slowly Warm the cup again Pour the mix into the mould slowly. Don't use a heat gun since it will ruin and disperse the colours in the mould if u have any. Don't use a blow torch either.( Unless your really have to, use it from a safe distance since it might make the resin stick to the mould. And make it hard for it to demould.) Use a safety pin to pop any bubbles if it's a small scale project.
You can avoid bubble since very beginning when you mix n stir the resin, the key is how to stir, i use T propeller i made my self and attach the propeller to cordless drill/screwdriver, and run it, make sure the propeller sink deep on the resin on the process, don't lift it until it mixed ..(when you lift the propeller that still run in the process it will instantly create a lot of bubble)..
Gracias a todos, por sus consejos, y experiencias. Me evitaron haser un desastre. Como principiante creo q este video es uno de los mejores en respuestas. Gracias ❤❤❤❤
Thanks for sharing, this helped speed up my pours! My fave is the hot water method followed by blowtorch after the pour. This is good for small pours, for larger thicker pours, anything over 3", I don't think you can avoid the vacuum pot if you want perfect results.
A clock behind every test would have been nice. I know you have a graph at the end but a clock during the whole video would have been better. In addition providing the graphs info at the bottom of the screen during each test would have been a good addition
You can also spritz 91% rubbing alcohol onto the resin after you pour into the mold. Works great & you don't run the risk of ruining your molds using a torch! 😉
@John Doe I use a fine mist of 91% rubbing alcohol in a spray bottle. After I pour the resin into the mold, I wait for a few minutes & let the bubbles all rise to the top. Then I lightly tap the mold & give a quick spritz with the alcohol. It pops the bubbles. I never use a torch or candle lighter in fear of accidentally hitting the silicone mold. These molds can be pricey so I don't want to ruin them. The 91% rubbing alcohol works.
I use a candle warmer..its like the perfect amount of heat..I don't know if these are widely sold qnymore..these were pre wax burner pots..you would put your candles on them after the wick was done and u still had good wax left. These were great to use for expensive scented candles. But the warmer works great on all my resin types so far. And since I stopped using wooden sticks to stir my epoxy resin I don't have too many bubbles to rid of anyway. Stirrers can't be made of porous substance or materials or else you create extra bubbles and slow n steady stirring and pouring wins the race!
Set up may be slight costly. But vacuum is most professional. It will not leave any bubble to chance. Technically, with vacuum, solvent concentration will reduce because due to vacuum it boils owing to its low vapour pressure (you can see that rise in level, that is actually solvent boiling at room temperature due to reduced vapour pressure !!) . Careful, with vacuum because in case if exhaust is not vented properly , one can get exposed to solvent vapour / fumes which is not a pleasant experience.
I also found a neat way I wasn’t even sure was gonna work but if you buy one of those mini fridges for like 20$ and turn on the heat and leave it inside for about 10-20mins the mold comes out nice and warm enough to pour ..
You have to pay attention to it, if it is a slow cure it won't harden, if it is fast cure, you need to check it time to time, but this wasn't that much to cause problem in 10 mins
Bro it’s been so long since I’ve looked at an old fashion clock that I thought hours were going by for a second and I was wondering what kind of resin he was using that cured so slow 😂😂😂
I think everyone should try this.. accidentally I did this and it was a awesome trick..I used iron stick instead of ice cream stick and I got less bubbles than mixing it with ice cream stick or any other.
Muchísimas gracias por compartir ese video, así vamos aprendiendo los que estamos empezando a meternos en el mundo de la resina, un saludo muy cordial desde Costa Rica, Centroamérica. DIOS lo bendiga.
Great video, needed to know exactly those things you helped me with - how to get rid of the bubbles from the epoxy and what was the other ingredient people in yt were adding - hardener. Ty!
I use an ultrasonic cleaner with warm water. Vibrates those bubbles right out and much cheaper than a vacuum pot (cost me £35). Takes about 6-8 minutes
The vacuum-method works great, but its barely possible to pevent a huge amount of foam. You also need a special vacuum-pump, which can't be used for many purposes. A compressor (usable for for many purposes) in combination with a pressure pot leads to slightly better results, but without foam building. However, both metods require special equipment, and payout for larger amounts of resin. And all methods shorten curing time.
Thank you soooo much. I am in doubt between a vacuum and a pressure pot. You gave me a really good vieuw on how the vacuum works. This wil definitly make my decision easier. :)
The problem with all those heating method is that the curing time will be shortened. Vacuum chamber is the only method that can preserve the curing time. Another method is to strain the resin through a small hole.
You can also refrigerate it to increase pot life. But yeah, heating epoxy is usually a no-go, unless it has like a 6 hour pot life or something ridiculous like that. Most epoxies have between 5 and 30 minute cure times and heating those will make them harden in minutes.
You could try putting your hands all around your mixing container and scream ,, get out ! You are surrounded,, 😂 Belgians and Canadians do this to clear the snot out of their noses
Well yes. But table top resins are designed to go on in thinner layers and usually have a smaller window to work with. Hence the blowtorch method. That’s really the only way you will de bubble TT epoxy since the layers are thin the bubbles don’t have far to go. But if a newby decided to try the other methods with TT epoxy, they’d probably only do it once and do more research. Ain’t one person that’s messed with this stuff done so without making a mistake. Lol.

You should include that these methods don’t always apply to all epoxies and highly dependant on volume cast. These methods are also applicable to degaussing not necessarily to once poured into your mold, especially if you are casting things in the resin. Heating your resin can help with removing bubbles, but accelerates setting, sometimes to the point of inducing cracking. Epoxy is s dangerous goods item, because it is flammable, so recommending an open flame is not wise. You were lucky as small quantities aren’t usually a problem. Vacuum is again fine for degaussing but not necessarily after casting. Anything that is not impermeable contains air, and as setting times are dramatically reduced, you often get honeycomb. Pressure pots are the best way but you fail to even mention it.
I think it is implied by his channel and his work that these are low volume casts compared to what you are warning off. We also use much safer resins than the old industrial ones you are thinking of that require masks and no open flames. Everyone either uses flame or a heat gun to coax the bubbles out of their craft pours. Definitely there are exceptions to every situation, thank you for your information. I’d love to hear more about the pressure canisters? I’ve seen these used a lot, but it does seem an elaborate set up. I generally pour with colour resins on canvas in layers, and if you start with less bubbles, you have less to fix in the end.
I think that depends what you are using as far as flammability goes. I use tabletop epoxy resin. It is not flammable. I use a bernsomatic brazing torch and have never caught it on fire. Polyester might, I dont know, i have never used it. But i agree that if you are using a table top resin, waiting 25 minutes isn't an option. If using a silicone mold i wouldn't use a lighter or torch as if you heat the surface too much it tends to melt Into the mold and destroy it at demolding. I would say that a vaccum chamber is the safest bet.
Update to my last comment: I have since purchased a vacuum chamber and pump. It is really the way to go. I pump it up to max -30 psi and let it set for about 5 minutes. Release the vacuum hit it with a the torch very quickly, careful to not over heat then vacuum and release a few times only letting it sit under vacuum for about 30 seconds. It seems to get rid of most of the bubbles. I've had good results with this method. P.s. when releasing the vacuum do it very slowly. If you do it too quickly you might end up splattering it all over the inside of you cacuum pot.
J P - may I ask what kind of vacuum pot did you purchase? Or could you maybe do an episode explaining more about them? I’ve seen everyone using them - sometimes before they pore getting bubbles out of the mixing container, or like you guys both referred to in the mold itself. But doesn’t that present a size problem for many molds (I’ve only seen canister chambers)? It just seems like it more and more a given that everyone was using a vacuum chamber on their channel in the last year and a half, but no ones really done a video how to get one, set it up or work with it. If you know of a great video or you’re going to make one, I’d really like to watch it!
I work in STEM and have been at an aerospace company. The pros use a centrifuge for basic stuff. For high reliability applications, they follow up with a vacuum. The 1-2 like that means way less foam since almost all the bubbles are on the surface. Oh and BTW the pros also don't mix by hand. They start with a swizzle stick mixer so what comes out the nozzle is already mixed.
I'm just starting to watch some of these teaching videos before I attempt my first project. I've had a FoodSaver vacuum sealer for decades and wonder if that would do the same job as the fancy vacuum pump? It came with several size plastic containers and lids and I only ever used it for storing things like flour and baking soda.
Tried the hot water method. Stirred the resign together, poured it into my glass bottles. Put the bottles in hot water. Took them out after a few hours. Left them over night and all four glass bottles cracked! FYI
Turns out the heart shaped glass bottles I used are hand wash only, not for microwaves and ONLY FOR COLD BEVERAGES!?! The heat in the chemicals must have made them crack.
No, I say the lighter is best ! Of course I haven't personally tested any of them myself so I could be totally wrong. But for the time frame alone, I'd choose the lighter. 🤷🏻♀️😉 Thanks for the video ! It was perfect for what I was hoping to find on bubble removal for resin. 👍🏻😍
This is a perfect video, thank you very much! I'm going to try hot water and the heating coaster, it's interesting! Hope plastic cup will not melt )) Using lighter may cause deformation of the top layer (or maybe it depends on a resin, because I had such an experience just for couple of times). It was really cool to see the vacuum machine effect! ))
Instead of a vacuum, I wou.d like you to put it in a container similar to the vacuum but put it under pressure. Meaning apply pressure to it like an air compressor does this would compress the liquid forcing the bubbles out. Putting it in a vacuum causes it to boil as you saw when doing this. I belive putting it in a pressure chamber will push the bubbles out faster. Also, when mixing try to now wip it up as that is what is putting air bubbles in it in the fist place. Hope this helps.
Interesting. I've seen a pressure chamber used for two-part silicon molds with resin to get air bubbles out. Will a positive pressure chamber work like the vacuum chamber?
I've watched many videos on resin casting and it seems (I have one now) pressure pots work great just limited on size and a vacuum pump is used more pulling moisture out of wood. I did a pour with my pot and after 8 hours had zero bubbles. It was clear as glass. But after experimenting I've found many times I like the Bubble look especially when pouring dice. If pouring for wood turning you want all those bubble out or it can chip easily.
Whenever I use heat..I put it in a bucket of ice water after and that slows the set time...also if you keep the resin moving..just roll it around the container a few times every few min helps as well
We build fishing rods and we do this all the time, if you stire it up slowly it helps but heat does the best. We do equal part B and A and after mixing it we hit it with a flame, if using a metal cup you can flame it on the outside and the bottom of the cup, if all the bobbles do not go away just use a straw and blow on the epoxy and the bubbles will disintegrate.or pop.
My question is when you use the pressure pot now you have an over flow mess on the bottom of your pot. How do you clean that out or do you just leave it in there? If you leave it does it ruin the pot after so many overflows?
@@thislonelyplanet Hi Thank you for that. Thing is I miss wrote my question I actually ment the question for the vacuum pot & wrote pressure by mistake. The video used the vacuum without anything in the bottom to protect it from the overflow so I wondered how they took care of that overflow. I am saving up to get a pressure pot though they are the better choice.
A COUPLE PRECAUTIONS: Using a lighter can ruin your mold, no matter how carefully you use it. It can melt the mold to the resin and will be no good after that. Heating the resin before use DRASTICALLY reduces the pot time. If it starts to cure in the cup and can't be used, and you throw it in the trash can, it can start a fire. If you can manage it, a pressure pot is still the best way to go!
You forgot two of the best known methods: 1. using a syringe (works for larger bubbles especially when you have a structured object in the resin) 2. VIBRATIONS
@@BioClone Interesting idea - though centrifuges are used for separating blood cells right? I wonder if hardener and resin would separate while still in liquid form, which would mean you'd end up mixing again?
@@ravenskyproductions2668 I guess we forgot it's an educational video that shows how to fix rookie mistakes, but there are some resins that have more bubbles than others. Might as well KNOW how to avoid them or clear them if we can :)
I feel like this video should come with a disclaimer. If you don’t know how to get bubbles out of resin, you may not be aware of potential problems with these methods. It should be noted that with all but the vacuum pump method, pot life may be an issue. Heating many / most epoxies can cause thermal run away and ruin your whole batch, possibly your project, and best case scenario will drastically shorten pot life.
There's a sixth way. If you're using silicone moulds you can warm the mould in the oven before pouring the resin in it. Take the mould out of the oven, let it air for a few seconds and then pour the resin in. The warmth of the mould will get rid of the bubbles in the resin.
Any degree? Time?

What also helps is mixing the two parts gently. The harder/wilder you stir, the more bubbles you create.

However, I do use my torch every so often after the epoxy is applied to my tumbler surface instead of a heat gun to pop bubbles. Using the heat gun would move your epoxy around because it blows hot air. If your intent is to move your epoxy to get motion in your design then a heat gun is the way to go. There’s no one way to do things. Continue to browse RUclips for methods that works for you. Good luck
@@laurawhittaker7217 “continue to browse RUclips for methods” is basically my answer to all of life’s questions
@@Dante190186 I do, I actually just place my closed bottles back in a bowl and fill up with hot tap water, by the time I need it again it’s ready for me. You’ll see the harder will be a lot easier to mix with the resin when warmed up.
My first resin pour was in 1974 omg. BEST way if you make art to sell and need to be very productive: HEAT room to 72 degrees or more, HEAT resin in a warm water bath - I even add my container to water bath, pour in resin on side of container, pour in hardener on side of container, stir slowly in figure 8 scraping sides, bottom, and stir stick for at least 3 minutes, depending on resin brand. Voila!
Also mixing fast will cause bubbles and when pouring your hardener and resin you should pour it against the side of your cup instead of directly in to avoid causing more bubbles.
But the mixing it together cause bubbles
Basically like pouring a pint.
Aoleon I always get bubbles no matter what. Even after I’ve used a torch or a heat tool to pop them. It looks smooth but when I come back there are more bubbles and things that look like strands of hair but it’s not hair.
I’m sure they just mixed it fast to make bubbles just for the bubble eradicating video.
@@malakaziz3642 Lol, no. If you mix it slowly for 10-15 mins, it will be bubble less, maybe only on top, and you can use alcohol for that.
Interesting! Though working with larger pieces, I think I’d be concerned that my resin would set faster than I would like it to set. Still, I do believe storing the resin and hardener(prior to mixing) in a warm area could definitely be helpful. The comments on this post were especially helpful. 😊
I always found that a good way to prevent bubbles is to take more care while mixing - mix more slowly and for a longer time - you can achieve equally thorough mixing while introducing almost no air and the overall time you take out of the resin's pot life can be similar as when you mix vigorously and then try to get air bubbles out again.
Have you tried a stirrer with a wide paddle well below the surface and a narrow stem?
Is there a particular stirrer that you use?
@@lpmwalker_of_sky1903 I use a long stick of 3mm acrylic, about 15 mm wide. because of the flat edges, it lets me scrape the bottom and the walls of the mixing container. But as Wiliam suggested, something wider at the bottom and with a thinner stem could work well too. But it would have to be a stronger material. Also, having a rectangular mixing stick allows for esier removal of hardened epoxy, so you can reuse it almost indefinitely.
Right. I see so many go at it like they are whipping egg whites into a meringue 🤪
What you say is true for most brands of casting resin. Unfortunately, I discovered that a certain brand is horrible about bubbles - no matter how carefully I stirred the parts together I ended up with so many teeny weeny tiny bubbles that I couldn't see without my glasses. Sadly, because of my laziness about finding my glasses when I was pouring resin to make shot glasses for my friends for Christmas, I didn't see the stupid little bubbles and ruined the gifts I was making. Let me know if you want to know what brand of resin I'm referring to, I'd be happy to tell you in a private message or email.
Storing part "A" and "B" in foam insulation with coaster warmers in both storage chambers makes the resin thinner so it mixes easier and helps it last for up to 7 -12 years of storage. A few bubbles form in the first place when using pre-warmed resins. Polishing the surface with a propane torch is a "MUST-DO" step in any case since pouring creates a few extra bubbles at the edges and corners.
The hair dye gave me the answer I needed cause I was wondering who I would get "flesh" color in my resin and how to get the bubbles out thanks mate ur a life safer🙏🏼❤️
Learned a nice trick - heat. But flame might not always be desirable because the chemicals may be flammable. As a MicroSection Tech, I've made plenty of resins and mounted quite a few specimens. Air bubbles were always an issue. The way I removed bubbles was to incorporate a centrifuge. Would drive resin deep into the mold and molded parts while forcing the air out. And it took typically 2 to 5 minutes, depending on the part being encapsulated.
The vacuum chamber - I wouldn't recommend that. I saw outgassing going on in your video. Meaning there was no air bubble but one appeared as the gasses were pulled out of the chemicals. And sometimes that can leave even more bubbles.
Oh, and your chamber lid had a crack, which appeared to be worse at the end. Vacuum chambers can be dangerous when they burst. Sure they implode, but that just means high velocity shrapnel flying around and bouncing back up in your face. I would not recommend vacuum.
This gives me an idea with an old salad spinner....

Will that burn the silicone ?
Tae Aubrey yup
@@taeaubrey4309 if you're an idiot and have no idea how to use a heat gun. You have to REALLY fuck up to burn silicone
Here's one. If you use epoxy with wood, say in a table or jewelry box, you need to paint a layer on the wood first and let it set. UV, regular, doesn't matter except for cure time. Or, you can use shellac first (the clear sanding sealer type). The goal is to coat the wood so it doesn't off-gas. Wood is porous and has trapped air. Wood breathes. You can pour epoxy, flame out the bubbles, and come back well after you can do anything about it to find bubbles. That's the wood off-gassing. Heating the epoxy in this case, no matter the method, won't work. The issue is the wood breathing. Seal your wood, preferably with epoxy, and you won't have a problem. If you also fill any seams with UV resin, you can set it under a strong light or take it outside under a sunny sky for about 30 minutes. That way, when you pour, no leaks either. Never rely on the wood glue in a joint to keep the resin where you want it. You'll be sad.
wow! I use wood all the time and I'm so fristrated because I almost never get a piece with a smooth finish. I put gesso on it... but now maybe I should just do a layer of resin first...
I recently created black resin to coat a guitar using black alcohol ink. Used about 50 drops of ink in a small cup of mix. Yes it made the mix thinner, which was good for my application, but the alcohol made the mix bubble free in the cup before pouring. Worked great.
by the time I wait for any of these methods my resin is already curing
yeah mine says its good for 45 min after you mix but its more like 20-30min.
Yea same here mine only lasts 40 min before it starts to cure. And coz of the heat where I am it cures a lot faster
then you may need to change to a slower resin, there are many types of resin😉😉
I put my mixing cup into hot water and mix the resin while the cup is in the hot water. Helps so much! Barely any bubbles. I also mix very slow. Then I hit it with the touch once its applied and it usually get the remaining bubbles out. I use a resin with a 30 min window
Shaneese Hillemann smart!!
Poured resin for the 3rd time today. After my second pour yesterday my resin was filled wit micro bubbles. I put my resin bottles in a warm water bath then when I poured I stir slowly while aiming my heat gun to the resin. Then pour slowly into the mold. Let’s see what the results are when I pop it out tomorrow. I’m learning with each pour trying to not get upset on my 2 fails. Hopefully this 3rd pour will be better. I’m trying to preserve my rare cactus blooms. Learning the art of resin is expensive and strsssful 😅😩🥴🤯
And very dangerous without proper safety measures and an extremely well-ventilated area.
@@sand3882 really..is it very dangerous ?
@@Isha_Sethi , it's extremely dangerous. Extremely. Some will tell you otherwise, but by the time they find out they were wrong, it will be too late. Don't get me wrong, resin can be gorgeous and OK if done outside with a respirator and eye protection...and in fairly short sessions. About 10 years ago, I met an artist at a top 5 art show in the U.S. When I asked her about her art, she told me she had already had to give that part up because of the damage it had done to her lungs. She was probably 40-50. Many young people now are just jumping in because no one has told them the dangers or the didn't bother to research. Have fun, but please be careful.
San D there’s actually a ton of brands now that carry non toxic resin
@ilovejewelyn You can't preserve flowers in resin without drying them first is silica beads/sand. If you don't do this, the flowers will decay in the resin and turn black or brown due to the moisture in them.
You guys do know that heating up the activated resin SIGNIFICANTLY accelerates the hardening shortening the working time and depending on you batch size and temperature can auto-ignite.
Hot water made mine so hard lmao it was my first time makin a ashtray. This video caused me my whole cup of this stuff😂😂sit it in hot water my butt lol
Same happened to me, wasted a whole cup of resin doing this! Ended up with a blob of hardened gooey mess.

Exothermic run-away is no joke
@@williamchamberlain2263 I'm pretty sure chuck norris directed that movie, exothermic run-away...
To all those mentioning the wooden stick and stirring slowly. He was creating bubbles for his experiment to show how the approach worked or didn’t.
Yes some are just perfectionist
I was gonna say 3 and 5, 3 is much cheaper and only a few minutes wait. You can also heat the molds to 150F or so (Check the temp limits on your mold silicone) then pour the resin in and the bubbles disappear as you are pouring. It works really well just make sure of the heat toleration's of the material you plan to use first. 3 has been a go to for me since they came out and a usb humb can make it easy to have multiple colors going at once for whatever you may need.
How long do you leave it on the heated coaster .
I’ve been doing the hot water method since I first started resin. I researched resin and everything for months before ever trying to use it and that was my very first way and my only way beside the lighter at the end for the few minor air bubbles I get when it’s poured into the mold
Same here. Exactly
Can you please tell me the name of resin you use
@@chamathfonseka7529 Not sure to whom your query was directed, but for me personally, I like Stone Coat and Faux Rizzle the best.
This is something that you'll have to explore for yourself though and figure out what works best for your particular style of art. For instance, I absolutely hate "Art Resin" and multitudes of others love the stuff. I find it fragile, soft and intolerant to polishing out defects. My only real advice is to buy the smallest quantity that a company sells, and see how you like it and do that with several companies before you decide who will be your go to supplier. Resin is absurdly expensive and you don't want to get stuck with 2 gallons of stuff you don't like and hundreds of dollars wasted.
Best of luck to you. 🙏

Realize that yesterday when I get my hands covered with resin and washed them with hot water 🕳🚶🏽♀️
And I just spent around $200 for a good pressure pot! I like the heated coaster method and I'm going to try it, mostly for the ease and simplicity. A vacuum chamber can be extremely messy! You have to sit and watch it, controlling the amount of vacuum, or the resin will turn to foam and spill all over the inside, as it did a little in this video.
UPDATE: I used the heated coaster for a while, and it has ruined all of my silicone cups - the bottoms eventually became brittle and the resin wouldn't clean up after it dried. I now use the hot water method, before putting the mold in my pressure pot. I also got a vacuum chamber, which I will use for silicone to make molds with.
Thank you so much Miley onDisney 😊
Pressure pots are more effective anyway!
The trick with forced convection from heat seemed good but I suppose it will accelerate the curing which could be a problem in many cases when the pouring time is critical.
That's why I would go for the vacuum method.
If you warm the two separately before you mix you won't introduce as much air in the first place. Then follow up with above of choice.
This works best for me
😮
How long do you warm it up for beforehand?
How warm to heat up?
IDK what epoxy he used, but most will start to cure if left alone, mixed for 15 minutes. If you place your measued epoxy in a water bath before you mix you shouldn't get bubbles, if you still get some place it back in the warm water for a few seconds.
Do you mean to put both the resin and the hardener in warm water separately before mixing them? How warm?
Mine doesn't cure if I left alone for 20 mins alone. This isn't that much epoxy to cause big troubles, especially if it is slow curing. Which can handle even 5-6cm depth.
I put part A in my Scentsy warmer with a small amount of water
@@Dragonflydesign_666 ohhh maybe I should try that.
For the water bath method, I usually keep the resin bottles part A & B in a bowl of warm water for a few hours, and the mixture cup in the bowl of warm water also while stirring for at least 3-4 mins.. ++ Avoid lifting the stir stick in and out of the mixture and be very careful not to get water inside your resin cup, I heard it can ruin the mixture completely!
Hi BuzzingFish. Miley's comment aside [though probably true], I want to comment that your video without vocals gave a very visual and informative understanding of how to get the bubbles out of resin. For most enthusiasts and DIY startups like myself, the "pressure pot", though probably the best solution, would be an added investment. Thanks for the insight. Cheers
The pressure pot is good for getting rid of bubbles after pouring the resin. These are good methods to get the bubbles out before the pour, especially if it has a long work time so you don't have to rush before using it. The fewer bubbles during the pour means less bubbles for the pressure pot to squeeze, which can affect the final product as the resin level will go down as the bubbles shrink.
FYI There are two different things being talked about here "Pressure Pot" which adds pressure to the chamber with a compressor and a "vacuum chamber " with a vacuum pump (which was used in the video)
FIRST METHOD!
Mix it SLOWLY!
It cause less bubble and as time goes your resin will be thicker which is better.
Lighter is not recommended it can ruin the molds because it is hotter than those can handle.
Can I use a foam board as a mould against the resin? Is there a solution you know of that I can use so the foam board can peel away?
I thinks he's mixing fast to introduce as many bubbles as possible.
@@madtabby66 Just do normally then. Slow mixing is the number one rule
@@MovingT5 Apply strips of clear cellotape on the foamboard for easy demolding. Not sure my comment still meets your enquiry but maybe someone else might benefit someday
Works perfect for my UV resin! I just mix in my glitters or coloring, and let it sit on the electric cup heater. Gets rid of the bubbles perfectly and is so much easier to pour! I can get rid of any surface bubbles easily as well with a mini blow torch or heat gun
I tried the warm water method, and although it removes a lot of bubbles, it affects the solidification time enormously. I usually have a dry, solid model in 24 hs. With the warming in warm water it took 5 weeks to get solid! So, it is a no-go.
Thanks for sharing your experience
I use a TON of rubbing alcohol - not necessarily on the resin itself (though there are some methods I would love to try), but as a cleaning agent for most things around my desk. I avoid open flames at all costs. Heat guns are really inexpensive and work great... for regular bubbles. I'm still having problems with microbubbles and am looking at vacuum chambers as we speak.
I am fairly new to resin and mostly use UV resin at this time. I do use a flame to get rid of some of the bubbles in the mold. But I have found a spraying a small amount of alcohol works for me as it evaporates quickly. (I only use the alcohol after using the flame as we all know, alcohol is a flammable.)
Just a heads up. I wasted almost ½ gallon of resin, by putting it in warm water. It pulled bubbles up but hardened before I could mix colors.
Warming them separately works a little better.
Yes I literally just had this happen and was so confused and pissed didn't know it can do that
I didn't work for me either. Mine hardened in less than 10 minutes.. so frustrated and pissed.
Always remember to stir carefully and slowly, minimize the amount of bubbles
I think the atmosphere temperature as well as the brand of resin has a lot to do with bubbles appearing. It was so cold here before Christmas, even inside the house... I never thought the temperature of my work space would matter as much as it does.
Tips to avoid bubbles
Warm both the hardener and resin in their containers.
Pour both of em slowly into the mixing cups
Mix gently and slowly
Warm the cup again
Pour the mix into the mould slowly.
Don't use a heat gun since it will ruin and disperse the colours in the mould if u have any.
Don't use a blow torch either.( Unless your really have to, use it from a safe distance since it might make the resin stick to the mould. And make it hard for it to demould.)
Use a safety pin to pop any bubbles if it's a small scale project.
Check out this video, it will teach you how to remove bubbles~~~~~ruclips.net/video/zxG-ntrdoJo/видео.html
You can avoid bubble since very beginning when you mix n stir the resin, the key is how to stir, i use T propeller i made my self and attach the propeller to cordless drill/screwdriver, and run it, make sure the propeller sink deep on the resin on the process, don't lift it until it mixed ..(when you lift the propeller that still run in the process it will instantly create a lot of bubble)..

A pressure chamber is actually recommended for resin, due to the exact thing that happened in #5. Other than that, SUPER HELPFUL!!
Thanks for sharing, this helped speed up my pours! My fave is the hot water method followed by blowtorch after the pour. This is good for small pours, for larger thicker pours, anything over 3", I don't think you can avoid the vacuum pot if you want perfect results.
Warm water method works for me. Remember you have to warm resin and hardener in separate cups ! then combine.
But remember.. the resin is way thicker than hardener so you want to make sure that you have equal parts.
Really useful comparison!
I would love to see 2 additional methods compared: spin-molding using a centrifuge, and using a vibrating table / agitator.
I have also tried putting it on top of the tablesaw and turning it on for a few minutes.
interesting! Never thought to do this

Had he not used a clock the first time, you would have never said that. The graph in the end was all that was needed.
the chart is super helpful, thank you for making this vid!
You can also spritz 91% rubbing alcohol onto the resin after you pour into the mold. Works great & you don't run the risk of ruining your molds using a torch! 😉
@John Doe I use a fine mist of 91% rubbing alcohol in a spray bottle. After I pour the resin into the mold, I wait for a few minutes & let the bubbles all rise to the top. Then I lightly tap the mold & give a quick spritz with the alcohol. It pops the bubbles. I never use a torch or candle lighter in fear of accidentally hitting the silicone mold. These molds can be pricey so I don't want to ruin them. The 91% rubbing alcohol works.
I use a candle warmer..its like the perfect amount of heat..I don't know if these are widely sold qnymore..these were pre wax burner pots..you would put your candles on them after the wick was done and u still had good wax left. These were great to use for expensive scented candles. But the warmer works great on all my resin types so far. And since I stopped using wooden sticks to stir my epoxy resin I don't have too many bubbles to rid of anyway. Stirrers can't be made of porous substance or materials or else you create extra bubbles and slow n steady stirring and pouring wins the race!
That's a very useful tip.
Every time I made jewelry for accessories, there was one or two bubbles, so I could untie them well. Thank you.
Set up may be slight costly. But vacuum is most professional. It will not leave any bubble to chance. Technically, with vacuum, solvent concentration will reduce because due to vacuum it boils owing to its low vapour pressure (you can see that rise in level, that is actually solvent boiling at room temperature due to reduced vapour pressure !!) . Careful, with vacuum because in case if exhaust is not vented properly , one can get exposed to solvent vapour / fumes which is not a pleasant experience.
Good video! I think I'll go with the warm water method for my first project, looks simple and effective. Thanks for making this video!
yobrojoost, you are welcome, I'm glad you like my resin work, thank you. 😊
I also found a neat way I wasn’t even sure was gonna work but if you buy one of those mini fridges for like 20$ and turn on the heat and leave it inside for about 10-20mins the mold comes out nice and warm enough to pour ..
Don't leave mixed resin in a cup. It will cure. It happened to me while I was putting the add ins on the other resins I was working on.
You have to pay attention to it, if it is a slow cure it won't harden, if it is fast cure, you need to check it time to time, but this wasn't that much to cause problem in 10 mins
well i suppose it depends on the project as well
Bro it’s been so long since I’ve looked at an old fashion clock that I thought hours were going by for a second and I was wondering what kind of resin he was using that cured so slow 😂😂😂
I think everyone should try this.. accidentally I did this and it was a awesome trick..I used iron stick instead of ice cream stick and I got less bubbles than mixing it with ice cream stick or any other.

Great video, needed to know exactly those things you helped me with - how to get rid of the bubbles from the epoxy and what was the other ingredient people in yt were adding - hardener. Ty!
I use an ultrasonic cleaner with warm water. Vibrates those bubbles right out and much cheaper than a vacuum pot (cost me £35). Takes about 6-8 minutes
You are right. I have known this method in the past two days. I think this method is very good. I have only tried the five methods in my video. 😊👍

@@kgould8 Amazon. They sell pretty much everything.
Is there a difference without using water? cheers!
Just getting into this. Glad I don't need a vacuum pot on day one!
The vacuum-method works great, but its barely possible to pevent a huge amount of foam. You also need a special vacuum-pump, which can't be used for many purposes.
A compressor (usable for for many purposes) in combination with a pressure pot leads to slightly better results, but without foam building.
However, both metods require special equipment, and payout for larger amounts of resin.
And all methods shorten curing time.

Thank you soooo much. I am in doubt between a vacuum and a pressure pot. You gave me a really good vieuw on how the vacuum works. This wil definitly make my decision easier. :)
The problem with all those heating method is that the curing time will be shortened. Vacuum chamber is the only method that can preserve the curing time. Another method is to strain the resin through a small hole.
You can also refrigerate it to increase pot life. But yeah, heating epoxy is usually a no-go, unless it has like a 6 hour pot life or something ridiculous like that. Most epoxies have between 5 and 30 minute cure times and heating those will make them harden in minutes.
All is good, but I don't think that the last one (vacuum pamp) is such a need for us.
Thank you for sharing ❤️
You could try putting your hands all around your mixing container and scream ,, get out ! You are surrounded,, 😂

You should use a pressure pot, not a vacuum chamber with resin.
Thanks for providing detailed instructions for your video.
You’re using deep pour resin. The bubbles come out anyways. Try tabletop resin with these methods. A couple will backfire
Well yes. But table top resins are designed to go on in thinner layers and usually have a smaller window to work with. Hence the blowtorch method. That’s really the only way you will de bubble TT epoxy since the layers are thin the bubbles don’t have far to go. But if a newby decided to try the other methods with TT epoxy, they’d probably only do it once and do more research. Ain’t one person that’s messed with this stuff done so without making a mistake. Lol.

You should include that these methods don’t always apply to all epoxies and highly dependant on volume cast. These methods are also applicable to degaussing not necessarily to once poured into your mold, especially if you are casting things in the resin. Heating your resin can help with removing bubbles, but accelerates setting, sometimes to the point of inducing cracking. Epoxy is s dangerous goods item, because it is flammable, so recommending an open flame is not wise. You were lucky as small quantities aren’t usually a problem. Vacuum is again fine for degaussing but not necessarily after casting. Anything that is not impermeable contains air, and as setting times are dramatically reduced, you often get honeycomb. Pressure pots are the best way but you fail to even mention it.
I think it is implied by his channel and his work that these are low volume casts compared to what you are warning off. We also use much safer resins than the old industrial ones you are thinking of that require masks and no open flames.
Everyone either uses flame or a heat gun to coax the bubbles out of their craft pours.
Definitely there are exceptions to every situation, thank you for your information. I’d love to hear more about the pressure canisters? I’ve seen these used a lot, but it does seem an elaborate set up.
I generally pour with colour resins on canvas in layers, and if you start with less bubbles, you have less to fix in the end.
I think that depends what you are using as far as flammability goes. I use tabletop epoxy resin. It is not flammable. I use a bernsomatic brazing torch and have never caught it on fire. Polyester might, I dont know, i have never used it. But i agree that if you are using a table top resin, waiting 25 minutes isn't an option. If using a silicone mold i wouldn't use a lighter or torch as if you heat the surface too much it tends to melt Into the mold and destroy it at demolding. I would say that a vaccum chamber is the safest bet.
Update to my last comment: I have since purchased a vacuum chamber and pump. It is really the way to go. I pump it up to max -30 psi and let it set for about 5 minutes. Release the vacuum hit it with a the torch very quickly, careful to not over heat then vacuum and release a few times only letting it sit under vacuum for about 30 seconds. It seems to get rid of most of the bubbles. I've had good results with this method. P.s. when releasing the vacuum do it very slowly. If you do it too quickly you might end up splattering it all over the inside of you cacuum pot.
J P - may I ask what kind of vacuum pot did you purchase? Or could you maybe do an episode explaining more about them? I’ve seen everyone using them - sometimes before they pore getting bubbles out of the mixing container, or like you guys both referred to in the mold itself.
But doesn’t that present a size problem for many molds (I’ve only seen canister chambers)?
It just seems like it more and more a given that everyone was using a vacuum chamber on their channel in the last year and a half, but no ones really done a video how to get one, set it up or work with it.
If you know of a great video or you’re going to make one, I’d really like to watch it!

Autumn Heib wdym?
Exactly
I work in STEM and have been at an aerospace company. The pros use a centrifuge for basic stuff. For high reliability applications, they follow up with a vacuum. The 1-2 like that means way less foam since almost all the bubbles are on the surface. Oh and BTW the pros also don't mix by hand. They start with a swizzle stick mixer so what comes out the nozzle is already mixed.
Thanks for the tips! may I know what kind of resin you use?thats the slowest resin I've seen harden up
I'm just starting to watch some of these teaching videos before I attempt my first project. I've had a FoodSaver vacuum sealer for decades and wonder if that would do the same job as the fancy vacuum pump? It came with several size plastic containers and lids and I only ever used it for storing things like flour and baking soda.
Have you tried it?
Tried the hot water method. Stirred the resign together, poured it into my glass bottles. Put the bottles in hot water. Took them out after a few hours. Left them over night and all four glass bottles cracked! FYI
I don’t use glass, the resin ruins it and I hate to throw glass in the garbage.
Turns out the heart shaped glass bottles I used are hand wash only, not for microwaves and ONLY FOR COLD BEVERAGES!?! The heat in the chemicals must have made them crack.
Thank you so much for this video...Had so many questions and you answered them all...I love your work and thank you for sharing...God bless
No, I say the lighter is best ! Of course I haven't personally tested any of them myself so I could be totally wrong. But for the time frame alone, I'd choose the lighter. 🤷🏻♀️😉
Thanks for the video ! It was perfect for what I was hoping to find on bubble removal for resin. 👍🏻😍
This is a perfect video, thank you very much! I'm going to try hot water and the heating coaster, it's interesting! Hope plastic cup will not melt ))
Using lighter may cause deformation of the top layer (or maybe it depends on a resin, because I had such an experience just for couple of times). It was really cool to see the vacuum machine effect! ))
Instead of a vacuum, I wou.d like you to put it in a container similar to the vacuum but put it under pressure. Meaning apply pressure to it like an air compressor does this would compress the liquid forcing the bubbles out. Putting it in a vacuum causes it to boil as you saw when doing this. I belive putting it in a pressure chamber will push the bubbles out faster. Also, when mixing try to now wip it up as that is what is putting air bubbles in it in the fist place. Hope this helps.
The pressure pot doesn't get rid of the bubbles, it just forces them down so small that you can't see them.
Interesting. I've seen a pressure chamber used for two-part silicon molds with resin to get air bubbles out.
Will a positive pressure chamber work like the vacuum chamber?
I've watched many videos on resin casting and it seems (I have one now) pressure pots work great just limited on size and a vacuum pump is used more pulling moisture out of wood. I did a pour with my pot and after 8 hours had zero bubbles. It was clear as glass. But after experimenting I've found many times I like the Bubble look especially when pouring dice. If pouring for wood turning you want all those bubble out or it can chip easily.
Whenever I use heat..I put it in a bucket of ice water after and that slows the set time...also if you keep the resin moving..just roll it around the container a few times every few min helps as well
Might I suggest letting some air back in before the resin overflows with the vacuum chamber? It'll take a few times, but it'll eventually work.
Also, at the lower vac. levels, he is boiling out some of the more volatile components of the resin/hardner.
We build fishing rods and we do this all the time, if you stire it up slowly it helps but heat does the best. We do equal part B and A and after mixing it we hit it with a flame, if using a metal cup you can flame it on the outside and the bottom of the cup, if all the bobbles do not go away just use a straw and blow on the epoxy and the bubbles will disintegrate.or pop.
My question is when you use the pressure pot now you have an over flow mess on the bottom of your pot. How do you clean that out or do you just leave it in there? If you leave it does it ruin the pot after so many overflows?
@@thislonelyplanet Hi
Thank you for that. Thing is I miss wrote my question I actually ment the question for the vacuum pot & wrote pressure by mistake. The video used the vacuum without anything in the bottom to protect it from the overflow so I wondered how they took care of that overflow.
I am saving up to get a pressure pot though they are the better choice.
I will be getting one soon too. You must clean it up immediately with alcohol or I think Acetone
Heated coasters was the best so far
A COUPLE PRECAUTIONS:
Using a lighter can ruin your mold, no matter how carefully you use it. It can melt the mold to the resin and will be no good after that.
Heating the resin before use DRASTICALLY reduces the pot time. If it starts to cure in the cup and can't be used, and you throw it in the trash can, it can start a fire.
If you can manage it, a pressure pot is still the best way to go!
You are right, thanks a lot Miley onDisney 😊
@@SteveMcDonaldArtsandCrafts Hey, Steve!
Thank you for sharing, I've just bought the vacuum pot.
yeah, lemme just grab my vacuum pump...LMBO. Thanks for this video! =)
Cool my resin Hardend instantly by the 60° warm water🎉
Great vid where did you get your glass pot! I’ve used a torch and it works great but deep pours need a vacuum
That was great! I believe that the vacuuming and then putting it in a pressure pot is the very best.
you are right👍
Glad I clicked on this video!!!! I've been scared of not getting the mix just right and I never thought to use a scale like duh 😂
Make sure your resin can be measured by weight. Some are by volume.
Awesome 👌 🆒️ 🙌 👌
You forgot two of the best known methods:
1. using a syringe (works for larger bubbles especially when you have a structured object in the resin)
2. VIBRATIONS
Vibrations?
Yes vibrations?
Use something like a table sander strapped to the table to shake the bubbles out of the resin, where they burst on the surface
I would love to know if centrifugal force may be useful as everybody has a drill on home...
It works with blood, so there may be a chance
@@BioClone Interesting idea - though centrifuges are used for separating blood cells right? I wonder if hardener and resin would separate while still in liquid form, which would mean you'd end up mixing again?
Degas hardener and resin on a vacuum chamber prior to mixing, this will.temove moisture too. Mix and then degas again. Best method hands down.
Someone told me to put it on a whiring tumble dryer, the virbrations pushed the bubbles up.
Or your vibrator
thanks man for the tips i didnt know the hot water en coasters...its very . It will help me a lot
If I get that much of bubble from my resin I'll probably just change to another brand. 😂 Also you shouldn't stir that fast to avoid bubbles.
He’s trying to make bubbles for that video? Or did you just yeet that’s out of your brain lol:)
@@ravenskyproductions2668 I guess we forgot it's an educational video that shows how to fix rookie mistakes, but there are some resins that have more bubbles than others. Might as well KNOW how to avoid them or clear them if we can :)
I feel like this video should come with a disclaimer. If you don’t know how to get bubbles out of resin, you may not be aware of potential problems with these methods.
It should be noted that with all but the vacuum pump method, pot life may be an issue. Heating many / most epoxies can cause thermal run away and ruin your whole batch, possibly your project, and best case scenario will drastically shorten pot life.
