I have used a pressure washer sandblaster for about 15 years. It does just what you say and yes you need to get primer on the parts as soon as possible. I did a modification for the sand suction, I drilled a ½" hole in the bottom of a 5 gal. plastic bucket. I then ran an ½' copper pipe out of the bottom to which I attach the sand syphon tube. I elevate the bucket on a stand about 3' in the air, that way the sand is being sucked downhill to the nozzle. I have use that for about 10 years.
Keith is slowly converting his shop into beach front property.
😁
Great job Keith, the price, and no dust makes that a win-win.
Keith: Thank you for sharing certain details the other vids fail to show. Like the amount of pressure needed and the type of sand needed. I really appreciate that and you sharing how to set it up.
Thank you for uploading your video. As is typically the case, you are a restful individual from whom to learn.
I'd never heard of this use for a power washer.
Thanks for posting this video.
Keith, I got the same one to blast the body on my 1932 Ford and it worked great and no metal warpage due to heat, took 8 hours but well worth the time.
This is a great idea, for those of us who can't afford a regular sand blaster. Heard about these before, but thought they were cheap toys. Thanks for the review!
I ran a 100 hp compressor driven sandblaster, these pressure washer sand blasters have a real industrial purpose. They work great, especially when dust and noise is a concern.
Looks like I have a purchase to make.
I didn't know they existed. It solves my paint removal problem.
Thanks Keith.
John
Great video, thanks.
Us cat people instantly recognize the Tidy Cat bucket…
Meowrrrrrr…
That planner looks huge, thanks for sharing.
I have used one of these in the past and it was ok. Last old machine I repainted I just burned all the paint off with one of those leaf burning torches. It was fast and did a good job, those old oil base paints go up like gasoline!! The part never got over 200 degrees F so I don't think there were any distortion issues.
Always looking for ways to Blast old paint, Corroded Alloys etc. looks like something well worth looking at. Thank you for Sharing Keith. Dave from Australia
WOW!!! I never gave the pressure washer I have to be used as a sandblaster. I have learned so much from your channel...Thanks.
Thanks for showing the sand blaster attachment.
Thanks for the link Keith.
Looks to be a cost effective solution. Thanks for the video.
Great tip, Keith. Thanks!
Keith another benefit of wet blasting is it tends to not warp sheet metal like air blasting. We have a local wet basting company we use for that reason. I will be picking up this kit, probably from Northern, for small project. Good tip about the pool filter sand. Thanks. Glad you got a tickle about "Cutting the homeless in haft by 2025".
That sandblasting ppe/clothing combination made my day!
That dog was cleaning his privates with out the pressure and the sand
A good way to prevent flash rust , while still wet use lemon juice and with a soft scrubbing brush or sponge rub in lemon juice- this gives raw metal a green tinge and then you can rinse off and dry with no flash rust. Currently making my own wet sandblaster for my 3000psi petrol karcher out of a cheapie $30 air sandblaster gun. Have used it but as you say I need the correct nozzle and it will be spot on.
Great video, very useful information. Thanks!
Always good Keith thanks for sharing 👍🇦🇺
Nice video Keith... thanks, thinking of picking one up
Looking good Keith. We have a Vapor Hone at Dallas Makerspace, its a smaller scale of the similar setup but keeps the dust way down compared to traditional sand blasters
That's good investment for $100. I'll be adding that to my arsenal. I wonder if my HEATED pressure washer will be much advantage. Stuff sure dries faster when using 300 degree steam! For machined surfaces, gears, leadscrews, handles, gearboxes and such, I have recently turned to using lye (drain cleaner) instead of solvent and paint stripper. It strips EVERYTHING with a lot less work.
Looks very handy. My local monument carver (grave markers, tombstones, memorials, etc.) will blast large parts for a very reasonable cost, if you're only needing occasional or one-time use.
that dog was really going for it back there
looks like it works very well
Great idea--Thanks for sharing.
I think one of the greatest things about this method is the piecemeal method. One thing about setting up a commercial sandblasting deal is the urgency of cleaning and priming. Hauling all the pieces back and forth, weather, pricing, and time all work against you. Making it not fun to have to hurry hurry afterwards. Thanks for sharing
For about the price you paid for the pool filter sand you can get Black Diamond coal slag abrasive. I found it to work much better than sand, it does not contain silica and the particles are uniform in size so I had fewer clogs. I used a similar sand blaster sold by Northern Tool to refinish my boat trailer a couple of years ago.
Hi Keith, another very informative video
thank you very much, you have given me some sound advice in utilising the equipment that I already have ie very powerful industrial pressure washer on how to convert it to sandblasting and using water i will obtain the necessary parts and give it a go. Take care and stay safe my friend. Les
Enjoyed Keith!
ATB, Robin
Thank you🧐. Very informative.
Tractor supply has the sand you need. It's designed for this. They usually stock one or two grades. You'll want the finer version. The larger grains don't act like you'd suspect.
i believe you can prevent that flash rust if you do the following:
1. Wet blast
2. Add some passivating/rust inhibitor to your PW soap dispenser and do a quick wide spray of it using the soap tip.
Great video. Thanks
Keith, if you are near Valdosta , Tifton, or Statesboro check out Agri-Supply. They have small pressure post for standard shop compressors and a variety of blasting media. Also Northern Tool or Tractor Supply for your media.
Very nice video, thank you
Great idea. Im getting tired of using citris strip and grinding wheel for just about everything.
Howdy Keith. I'm done with my big wet blaster today. It's up for sale tomorrow. Cheap for you! Sorry, no PPE included : )
hi Keith, you forgot to mention the Tidy Cats sand container. They are great for storage. I have a dozen of them.
Thanks Keith.
If you happen to have a monument company near you that sandblast tombstones, you may be able to buy good blasting sand at a good price from them.
Monument?
@@mwilliamshs
Yes. Thanks.
Autocorrect.
@@dannyl2598 on phones, you can edit with the 3 little dots. Not trolling... hopefully helping. Have you heard/seen the dry ice method? No abrasives mess! Not sure of the cost difference.
@@emeltea33
Thank you for letting me know.
Now my comment won't be a monument to my stupidity.
Very informative.
Give crushed glass media a go, it would be sharper than any sand you may find and therefore may cut a little quicker. Also, as others have suggested here, try garnet, although not as sharp, it's harder, denser and flows nicely.
There are a lot of these types of things on Amazon in the UK and I assume the same is true of the US. I think the main issue is that the sand has to be absolutely bone dry for the system to work. The slightest bit of moisture will ensure the sand coheres, ensuring no amount of suction will lift it. Pressure washing + sand = wet sand.
The cheapo ones on AMZ are just that. Spend a little more like Keith and get a real lasting tool I suspect. Put your bucket of sand up on a ladder, and put a hole in the bottom with an adapter to let gravity assist. Get a bucket with a lid too.
There are (2) sand pit/mining operations just south of Junction City, GA, fairly close to you and real close to me. It may benefit you to look into their sizes and quantities available. Brown Bros. and Unimin....personally, I deal with Unimin. Try taping roofing felt over the machined areas...
One must admit that you were one handsome, becoming devil all decked out in your "protective gear." You had best hope that no one from GQ ever watches this video...we would all lose BIG TIME...no Keith...too busy on a photo shoot!! As always, a great video!!
Auto body shop supply stores sell a “metal prep” solution you can spray on freshly sand blasted parts , just dilute with water and spray on parts then rinse with clean water this etches the metal and keeps the flash rust from happening.
Thanks for the tool tip, i will be adding this to my pressure washer set up.
If you mix sand and glass beads, it makes small toadstools that can mechanically lock the paint onto the substrate. It works particularly well on metals like aluminum that are hard to paint.
I've seen phosphoric acid recommended for stopping rust. Any input?
Once again Keith great video very informative thanks for posting awesome tool with many uses big hello from London uk god bless
Great video Keith. Have you used Ospho, and couldn't you use that to take care of the flash rust? It could also allow you to skip the primer step, provided you were going to prime the surface before painting.
rather than sand use iron granuals
does a good job on cast
I like to use coal slag or recycled glass, it's relatively cheap here. Strange enough I bought that exact setup earlier this year 😉
how did it work with the glass is it any good
might want to look at "hold tight" for bloom prevention.
Would it work better if you used garnet or other blasting media?
Like the way u explain stuff. What was the psi and gpm on your pressure washer.
Currently unavailable.
We don't know when or if this item will be back in stock.
I bet you could mix in a little garnet and shorten the sand supply hose and get a bit more aggressive abrasion
Looks like the dog enjoyed himself a out 13 min in.
would it be an idea to contact a local, if you have one, water jet cutter to see if they would give you some used garnet? I understand that they don't re use it for cutting but once dried it should still work for your purpose.
What size of pressure washer did you use?
Dog putting on its own show....lol!
One thing I learned no matter what type of blasting you use or type of sand, don't do it in your driveway. It will track everywhere. On your shoes, on the car tires, your dogs feet. ..
who much time you spend sand blasting that machine?
I wonder how this wold work if you removed the suction hose from the bucket and used a pressure pot, similar to what harbor freight sells, to feed the blast head. The feed rate at the pot would have to be regulated as to not overwhelm the capabilities of the head. I know that wet sand prior to the increased velocity of the head is bad, so maybe a trickle feed to the head with just slight positive pressure.
Any way to control the amount of media at the nozzle Keith ?
Keith, approximately how much time does it take you to wet blast a square foot of surface? I'm looking forward to hearing how this rig works on heavily painted and heavily corroded surfaces in your future videos!
I guess one has to dry or oil the metal quickly before it rusts again. Also I would guess another advantage of using water is that it prevents a static charge from building up like it does with regular sandblasting
Use a rust inhibitor in the PW soap dispenser and use the soap tip after blasting to solve that problem. Also, being wet, no worries about silicosis using sand.
good job,try some aluminum like a outboard motor or something.
This is not a criticism, but just a question about the silica dust hazard: The silica dust particles are created when the sand particles shatter upon impact. I understand that those silica dust particles are captured in the water slurry with this pressure washer method, but does this not merely transfer the dangerous particles to a pile of wet sand that will eventually dry out? Is this not similar to asbestos particles that will later become dry and airborne? Are we only temporarily avoiding a problem and moving it to another time/place/person?
Another option is let it flash, and hit it with ospho, or another converter and it’ll create a nice barrier as well.
Hey Kieth, just curious what pressure/GPM washer you are using?
After reading the description, one might suspect Keith was trying to become Spider-Man.
What PSI pressure washer did you use in the video?
quote of the week "get down up underneath the bottom"
What size pressure washer are you using? Maybe you said and I just missed it
If I have a big machine to blast I just rent the pot and big 500cfm compressor for a day, about 500 all in. Always worth every penny in my opinion.
Looking forward to seeing this planer come together.
so tell me about that gantry, I could use one
Pretty sure it will do this but... will it work with crushed walnuts?
I wonder if you could add a bit of air pressure?
How many bags does it take to do that piece
Did you change the color?
Keith, can you use regular blasting sand? That's going for about 5 bucks a bag around here, and IIRC, it's 70 pound bags. It is very fine sand though.
Fine sand doesn't blast well in a suction wet blaster.
Late to the party as usual. Keith, what are the specs on your pressure washer GPM and PSI. Thanks. This looks really useful.
How many PSI pressure washer did you use?
There's awful lot of hose in that attachment, I would cut it much shorter to decrease the drag against sand. You would get much more sand mixed in the water and get better results. I think now you are basicly just pressure washing.
YEP - the hose is FAR too long. 6 or 10 feet would be move than enough
Keith, did I miss the amount of pressure you have from your pressure washer? What is the minimum amount to make this work?
I have heard of plastic media blasting & ground walnut shells blasting, with this unit can you use plastic or walnut media instead of sand if there is no difference in price?
You don't want to wash a ton of plastic particulates into the environment. Plastics are for blasting cabinets and for soft materials.
There is/was a product that when sprayed on to rust "turned it black to a inert rust, might work well on the "flash rust."
I neglected to add that it is/was a automotive body product
What are the specs on your pressure washer?
Please post a link or add to the description page the chart of reference for the tips.
I have a lower psi electric pressure washer Sun Joe SPX4001 2030 PSI 1.76 GPM 14.5 Amp
I wonder if it would be worth the effort, I wonder how the psi of pressure washer sand blasting compares to an air system like ari psi/cfm equals water psi/gpm?
The recommendations with the used one that I picked up was 4 GPM.
Not sure about the pressure. I would think that the ceramic nozzle size would be a factor as well.
How did you deal with flash rust?
I've done a fair amount of pressure washer blasting. First thing you need is a pressure washer that will flow at least 3.5-4gpm. The higher the better and the faster it will blast. This flow is what pulls the sand up the siphon tube and throws it onto the material being blasted. Pressure/psi is far less important and anything from 3000psi up is ample. So a cheap $3-600 gas pressure washer won't work, so don't waste your time/money.
I've been using a 2200psi and a 2400psi 2.5 gpm washer for over 20 years. No problem pulling sand up the tube.
Wrong, I've got a standard 3g 3100psi B&D pressure washer and it works better than Keiths actually.
Tip- Hang the bucket or place it on a ladder at head height.
Spend $5 and knock a hole in the bottom of the bucket and put an
adapter for the sand hose to use gravity assist.
Pressure is king in this application, more so than gpm.
Put some rust inhibitor in the soap dispenser and use the soap tip
to spray it down after blasting to prevent flash rust.
Play sand has rounded edges and works poorly.
.
If you are going to do a lot of blasting, you can recycle the sand/$.
Get an $11 wading pool
Get some plastic drop clothes and some scrap wood or PVC.
Rig up the drop cloths around the wading pool like an enclosed
shower, and blast in the pool so that most of the spray drips in it.
Drain pool, and either let the sand dry, or dry it in 55g drum over
butane stove bottle or small campfire.
Screed dried sand into sealable 5g buckets.
Arguable about whether this is worth it or not.
I have little doubt this is cheaper than farming it out too.
If you shorten the sand feed hose you’ll increase the sand feed rate.
Is 2600 psi enough for this set up? Thank you
For larger projects a guy should see if there are any mobile blasters or mobile dustless blasters in the area.
They're crazy expensive. 10 years ago I was charged $200 an hour plus travel and I was cheap.
Has anyone tried garnet in one of these? I know it’s like 10x more expensive, but I’m really curious if it’s worth it.
Not worth the cost for single use. If you can capture the media for re-use it becomes more economical.
