watched loads of videos and these are by far the most interesting and fun to watch and thanks for spreading the knowledge
Thank you for this professional, informative video!
Great video and it helped me a lot with my floor prep. Thanks for taking the time to make it.
You are welcome! Glad to help :)
Excellent info. Great safety info as well. I'll use this.
Subscribed. This is the best instructional video on the subject!!
You always work so professional safety I like you videos boss
Literally was going to ask you if you had a video of this as I was prepping a floor today. Thanks!
this is "actually" a very good tutorial, thank you :)
lol, thanks for watching William!
Thanks Chris, great video!
Love your videos Chris. Thanks.
I'll be back for this series for sure. I have a large garage that needs some paint!
Thank you so much. Great information.
You are welcome!
Excellent instructions!! Acid etching is very affective.
Thank you for sharing🤙
No part 3. Parts 1 & 2 are awesome. Will keep tuned in.
The details are a great help💪💪💪
Thanks for watching!
Your videos are fantastic! Thx man I'm looking for options on my shop floor. I do lots of fabrication so epoxy is probably out since i do welding.
Great videos man. keep it up. Glad I found you on youtube.
Thanks for watching!
Really enjoyed! Thank you.
Thanks for watching Chase!
Great videos!.. My garage has epoxy already but seems old and chipping, how should I prep to put down new epoxy.
Great video, i plan on doing this to my garage. What is the ratio of water to acid that you used
hey great videos I've been remodeling the entire garage and finally got to the point to do the last thing which is epoxy the floor...I live just south of Houston Texas...I was wondering what epoxy you use/recommend? I'm planning on doing it in the next couple of weeks..thank you
Would splats and patches of water based latex paint keep a water based epoxy from bonding to a concrete slab that's been diamond grinded already?
Nice work , what do you think about the porch and floor paint by sherwing williams? and Does it have the same performance and effectiveness as the epoxy in the concrete?
thank you
Thanks for this video. I have done a lot of projects my self, and with my wife, but this one for my garage i wasnt to sure of and didnt have the confidence to attempt it. Now that i have watched all the epoxy floor videos i am sure i can do this one! Thanks for all your vids, and keep doin em, they will be your legacy, thats how us old guys think. Perhaps you should make your own home improvement Blu Ray or DVD and pass it out to your family at Christmas...... Thats what i did, Legacy, its what old guys think about! Awesome videos for Epoxy garage floors, thanks again, Mike
Excellent advice,tips and tricks..
Glad you think so!
I have been also taught to agitate oil spots with hard bristle brush and top & bond any large salt pocks/ chips...what is your take on this? keep up the good work!!!
Why did you not tarp the shelves and cabinets?
How long did you allow the acid to sit before cleaning it
good job!!
I see that nothing was covered up. I’m guessing it doesn’t hurt the trim, painted walls or anything with overspray?
This is the process if the floor is already clean right? What are your tips if the floor has had sheetrock mud and paint drips, plus dust from sanding?
Do you have any recommendations for applying epoxy to advantech OSB flooring? Thanks
Do I need to etch the floor that has not been sealed as long as I have cleaned it well?
How long between putting it down and flushing it out?
Very helpful...couple of questions though. Is it not enough to just use a pressure wash nozzle on the hose? Or do you really need an actual power hi pressure washer too? Also, sure seems like he would be getting all that stuff in the garage wet. Might want to "hang" some plastic sheeting first, right? I'm gonna try Rustoleum EpoxyShield which comes with an etching product in powder form (add to water) so won't be dealing with muriatic acid. But for those who are, it would be helpful to give the dilution ratio of water to acid. Thanks!
Video's are great--Question...what about moisture coming up through the cement floor? I live in upstate NY and temp's vary from 110 in the summer to -20 in the winter and it is usually very green around here...(plenty of rain). Several video's raise the question about epoxy lifting away from the cement.
i have a concrete floor in a restaurant so washing with a hose then pressure washing isnt possible, would a mop and water bucket work to wash away or dilute the acid enough to paint it if i mop it out a few times?
thanks
Can you water blast with media to rough up the floor with a dustless blast machine
My question is who was you teacher Idaho??? Because you are so professional every single video you Surprise me the way you work 👍 I’m painter to for 10 years state California I always watch you videos to do my jobs when I have questions
Great Video and many thanks. What is the max time you would allow between etching and step 2? Could you etch and do step 2 the next weekend?
Yes.
How long to wait between acid etching and doing the epoxy? (how long before the slab is dry enough???)
I can tell when u pulled that mask off and said wow 🤣 I know the acid fumes got you 🤣
I noticed you didn't tape off the walls or trim? Is this something you should do? Also, how long should you let the Acid sit on the Concrete before you start diluting it? I noticed you started on the back corner and worked your way right to left, but then you diluted the acid from front to back meaning some of the acid was sitting longer than other.
I'm going to do my garage floor this week , my Gyrock doesnt go right to bottom of floor , it's about 4 inches above floor , should I do the sides of the walls the 4 inches??
Excellent video!!! One question, my sealant seams to be incredibly durable. Have you ever encountered a sealant that was not removed with the acid you showed? I was tempted to remove it physically but would rather acid etch if possible. Thank you so much in advance!
Diamond grind it until the shine is gone.
How would this process work in a basement?
Would you recommend doing this to a patio?
Very informative video man! Did you kill your grass blowing all of that acid into your yard?
You don't use a degreaser?
+Brock Allen This should be interesting... with what firm???
I explained to my 6 year old that acid will burn and turn dry concrete yellow and that is why the driveway was wet down.
I'm wanting to epoxy my concrete garage floor and stain the concrete immediately outside the garage. It's my understanding that the muriatic acid will cause problems with the staining process. Will washing out the acid from the garage onto the outside concrete cause problems with the process of staining, or will it be too diluted with water to cause any negative effects?
Do you have to scrub the floor after applying the acid?
should the concrete be damp when ur spray on the acid?
Did you have to wash the entire garage floor first with degreasers etc?
Does the acid get up greasy spots at all?
how much will yiu charge for a job like this ?if the client buys the paint.its a 2 car port garage
I just found your video's. Watched all 5, very informative. I like that. Curious about the etching though. How long did you let the acid sit on the floor before neutralizing and would this same 'etching' apply to a polished concrete floor, or should that be sanded and primed?
As soon as I applied it to the whole surface I removed it
What is the mixing ratio of the acid and water?
Great Video. Can you go over old paint if not whats the best way to remove it.
+The Idaho Painter Thanks I will keep watching your videos and I will check out your store.
What do you do in the case where you want to have epoxy floors in the interior of the house. obviously flushing the acid out is a problem, would sanding be the best option for prep? thanks
Diamond grind it
How many gallons of the acid is needed to do approx. 500 sq ft.?
Don't you have to wash baking soda in the concrete after the muretic acid to neutralize the concrete??
You don’t make any mention of what concentration of muriatic acid you’re using? One gallon can have a range of 14% up to 33% muriatic acid. The big box hardware stores usually sell 14% concentrate. A pool store sells 33%.
What type of epoxy did you use?
So you don’t need to scrub the acid in? Just let it do the work?
When you begin the rinse process, should you be worried about the water splashing residual acid onto the walls, shelves, or wall-mounted benches? I noticed that none of these were covered nor were their contents removed.
Yes.
How much did u charge for a job like that? Or did u charge per square foot?
howdy, dont you brush it afterwards instead clean it with water?
Do you have any suggestions on how to keep things relatively dry on the walls or built in cabinets during the power washing stage?
Drop plastic and tape around anything you want to protect
Do you prefer acid etch over grinding? I’m in NY, also do you find the down time between prep is longer with acid etch Vs grinding because of the dry time from the water?
Hire a coatings company that uses diamond grinders and industrial grade high solids product if you want it to last. Painters paint floors.
How long do you leave the acid on the floor?
Also can you do this over a previously painted floor? Thanks 🙏
No - you have to mechanically remove the old paint with a grinder or something like that.
How long do you leave it on?
Or diamond grind the floor so you don’t have to deal with acid and your floor will stick indefinitely. If you diamond grind the floor, you can coat it immediately after with no hazardous materials and environmental contamination. The acid lays in those joints and will rear its ugly head later.
what can happen if you don't use acid firs?
What is the reducer to epoxy ratio?
Thanks for the video. I'm wondering if the acid has adverse affects on grass, shrubs, etc.
Wet stuff down before,during and after...
I have paint on my garage floor. Should I use paint stripper before applying the acid or could I just use the acid?
painted floors are usually grinded, instead of acid. grinding will remove the paint entirely, acid will not unless you do it multiple times.
Ive done a lot of concrete coatings....we always used a sprinkler can to apply the acid but the sprayer seems to more cost controling
Yes, we use those too
everyone is saying not to add water to acid...is it then 100% safe to rinse the acid on the floor with water while trying to remove the acid from the floor?
When applying the acid, if a small amount splashes on the walls or shelves, does it run the risk of damaging it? Thanks.
We have never had an issue with that
what a great how to video. i work for a bldg solutions co. in toronto canada, and you are about as good as it gets. you should be going around the world training company employees, and making skids of money. preparation is everything, and you left nothing out!! your a big asset to the construction industry, and i hope everyone sees your video!!! cheers brother.
Thank you for the support David, much appreciated!
Hi, I painted my garage floor about 10 years ago with the Rust-Oleum 2 part epoxy. Over the years it has gotten to the point that I need to coat it again due to the floor being dirty and some of the paint coming off. I recently pressured cleaned the floor and got about 30% of the paint off doing so. My question is, do I need to remove the rest of the epoxy paint off or can I just paint over it? If I need to remove the rest of the epoxy paint how do you recommend doing so? I used a 4000 PSI 4GP pressure washer with a turbo nozzle and was only able to remove about 30%. I know Lowe’s sell a primer for floors that are already painted but since my floor has about 30% of the paint removed I’m not sure if I should go that route. Ant suggestions would he highly appreciated by anyone. Thank you.
If it is sanded well and has a good profile you can go over it
I'm assuming that nothing happens to the grass because you dilute it with water is that correct
You should neutralize the acid with ammonia and water mixture
Am in Ghana how can I buy some of your tools
How's it going? Been watching your videos for a while, but I had a question about the DIY epoxy in the garage. Is it a "MUST" you etch the concrete with the acid first? I'm getting a house built and am looking to do it like right away. Should I have to etch with the acid if the concrete is new, and will it make a big difference if I don't use it?
***** Okay, will do! I should be ordering some things soon from you. Thanks for all the videos, they're really helpful and informative. Keep em' coming!
G'day,
If I'm painting brand new freshly laid concrete. It's dried concrete only a couple weeks old. Do i still need to acid clean it?? Or can I etch it then begin coating?? How many coats do you do?? Always 2 coats?? Allowing each coat to dry atleast 8 hours?? Appreciate the assistance
No
I'd love to know how this was holding up after some time has past. Thanks!
It is still holding up to this day
Question for anyone here. I’ve etched this concrete floor twice already, while I do see some changes and is a little more porous, the majority of the floor still seems very smooth and not as porous as the edges. I used muriatic acid as the shown video but I feel like I need to use a better more potent chemical, what do you guys recommend? Looking at the H&C etching solution as an option, anyone has any thoughts on this?
Im not sure how easy it is to get, but I used to work for a commercial pool Building company, we would use hydrochloric acid, ,hydrofloric acid , or sometimes muriatic , and a hard bristle scrub brush, and scrub it really well, then wash it down, then repeat using TSP , then acid wash it once more, then TSP one last time, using scrub brushes each time. Seemed to work well.
What if the acid were to flow on an asphalt driveway?
Looks like about 2 parts acid to one part water? Can you just neutralize the acid with an ammonia solution, then rinse out?
wranglers2 a lot of people neutralize with baking soda. However, if you are doing epoxy it is better to grind down the concrete. Unless you want to wait a while to do the actual epoxy. When they water you have saturated the masonry with evaporates, it can leave bubbles in the epoxy and sealer. Etching is only beneficial when staining masonry. Check out www.ez-concretesupply.com .
I want to do this on my floor of my laundry room in my basement. There is a drain in the floor. Will the acid be a problem going down the drain? Thanks.
The city sewer line.
grind instead of using muriatic acid. its also quicker to rent a grinder for a day.
Does anyone know if this process works for exterior concrete floors? In my case its covered by a pavilion. Any advice is greatly appreciated!
If it is brush finished concrete, no reason for etch. Just wait 30 days for cure from original pour of concrete then use a concrete stain, DO NOT USE AN EPOXY FOR EXTERIOR APPLICATIONS. The etch is literally dissolving micro pits in the smooth, polished concrete surface which would otherwise hinder best adhesion and penetration of coating. Brushed concrete doesn't need this step. Powerwash would do well if its not new concrete.
I'm sorry this ish is funny AF... OMG 🤣🤣🤣🤣
Hey should we scrub it down it down with hard bristle brush?
No need
The dude!!!
Is it reccomended to acid etch a recently poured self leveling concrete floor?
I etch all
What if I want to remove an old epoxy coat that was not done well and is either cracked or peeling? Same process?
Diamond grind it.
When I bought my house they had already epoxied the concrete but now it is peeling. How do you remove old epoxy to re-coat?
Diamond grinding is one way to remove the old epoxy.
Apply acid with a roller to avoid aerosolizing the acid spray and getting acid on your skin and other places.
