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: 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 the post. I was just investigation and that unit is more than cost effective. Thank you
Keith is slowly converting his shop into beach front property.
😁
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.
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.
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.
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.
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 job Keith, the price, and no dust makes that a win-win.
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.
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.
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.
Thanks for showing the sand blaster attachment.
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.

@@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.
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".
I'd never heard of this use for a power washer.
Thanks for posting this video.
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.
WOW!!! I never gave the pressure washer I have to be used as a sandblaster. I have learned so much from your channel...Thanks.
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
that dog was really going for it back there
Thank you for uploading your video. As is typically the case, you are a restful individual from whom to learn.
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
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.
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.
Great video, thanks.
Us cat people instantly recognize the Tidy Cat bucket…
Meowrrrrrr…
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.
That sandblasting ppe/clothing combination made my day!
That dog was cleaning his privates with out the pressure and the sand
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.
That planner looks huge, thanks for sharing.
Thanks for the link Keith.
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!!
Another option is let it flash, and hit it with ospho, or another converter and it’ll create a nice barrier as well.
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.
might want to look at "hold tight" for bloom prevention.
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...
rather than sand use iron granuals
does a good job on cast
looks like it works very well
Great tip, Keith. Thanks!
Looks to be a cost effective solution. Thanks for the video.
Looks like the dog enjoyed himself a out 13 min in.
Looks like I have a purchase to make.
I didn't know they existed. It solves my paint removal problem.
Thanks Keith.

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
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
I bet you could mix in a little garnet and shorten the sand supply hose and get a bit more aggressive abrasion
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
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?
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. ..
If you shorten the sand feed hose you’ll increase the sand feed rate.
Dog putting on its own show....lol!
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
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.
Like the way u explain stuff. What was the psi and gpm on your pressure washer.
Thank you🧐. Very informative.
Very nice video, thank you
hi Keith, you forgot to mention the Tidy Cats sand container. They are great for storage. I have a dozen of them.
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?
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.
I could have sworn a few years ago I've seen Rucker sandblasting on his channel. Maybe he was borrowing that unit from someone? I remember it being an older red sandblasting unit.
Yes he has one, great for small parts but for these not so much
Just wanted to make sure I wasn't imagining Keith using a red sandblaster then saying he doesn't have one.
He did a video about upgrading his blasting cabinet I think.
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.
Great video. Thanks
Always good Keith thanks for sharing 👍🇦🇺
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 : )
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
The unit is not currently available on Amazon.....and I blame you. They probably sold out 15 minutes after this video came out. LOL
Yep! He did it alright and Google was tracking me and sending ads to my Facebook feed for alternative blasters. Go figure.
Same message here, but there was one on eBay for $80 shipped, so I took a chance. It came today, was slightly used, probably by someone that did not size their machine correctly like Keith said. Local box stores where I am do not stock the pool sand though, so I'm looking for other media alternatives.
Nice video Keith... thanks, thinking of picking one up
Enjoyed Keith!
ATB, Robin
Great idea--Thanks for sharing.
Great video, very useful information. Thanks!
I am not sure how this is in the states but in The Netherlands Silca sand is highly forbidden as a blasting medium since the sixties.
Oh I'm sure we'll get there, you know nanny states and all. Come on, we have "For External Use Only" printed on our curling irons, along with "Caution HOT" as well. NO SH!T SHERLOCK, but here we are. Time to take all those warning labels off and let the chlorine clean the gene pool.
It is permitted here so use at your won risk. Our gov. don't really care for us, just politicians after their own greed, not public service.
he said before he doing it wet so it ok. IF your doing it dry that where your problems come from. Wet is not the same as dry blasting
@@davidhoward2237 Yes I know Mr Rucker knows, but I'm sure there are buncha hee-haw's blasting away as we speak, with no protection.
"Highly forbidden" lol. You'd think it was radioactive the way you said that. What a bunch of nanny state wimps.
Very informative.
The media hose is FAR TOO LONG. It's amazing that you are getting any sand at all through that thing!
It'll work heaps better with a shorter run, like 6 or 10 feet.
good job,try some aluminum like a outboard motor or something.
Maybe not a huge deal for occasional diyers, but One drawback nobody has mentioned is lead from the paint getting released into the environment.
Not too many people dealing with lead paint these days
And at least it's getting wet down
Rather than dry blasting or sanding
No good letting it set into th ground but at least it's not footing though the air for everyone nearby to breath in
I agree that lead is an issue especially given the age of the machine. Do you do any testing of the paint using one of those lead testing probes?The wet system at least means that if there is lead it is not vaporized into the air. Yo may want to consider some sort of drain sump where you can collect the sand
Lead is a non issue in this case. Lead paint contains
Andrew Delashaw , How nice of you to have that all figured out for us.
Robert Hamilton: I also appreciate his time and effort!
I have little doubt this is cheaper than farming it out too.
Try paver sand it's just as course but its cheaper then the pool filter sand
particularly sharp sand
Tractor Supply has U. S. Minerals Black Diamond blasting medium. I find it works much better than any of the sands that I can get from the building supply companies and is priced about the same.

I wonder if you could add a bit of air pressure?
Good vid, slightly misleading with your cost info though. About $100 you quoted for the washer blaster, but the gas power washer clearly wasnt included in that price! Even a decent grid washer would double that and with the safety gear
After reading the description, one might suspect Keith was trying to become Spider-Man.
What size of pressure washer did you use?
quote of the week "get down up underneath the bottom"
Keith, did I miss the amount of pressure you have from your pressure washer? What is the minimum amount to make this work?
Once again Keith great video very informative thanks for posting awesome tool with many uses big hello from London uk god bless
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.
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.
I like that solution much better than the solution Doug over at SV Seeker used, but yea, he's blasting a 60+ foot long sailboat...
you know he had one of this type in his video and even say the right sand to use? He did it inside of the boat i think in some parts. The one he use is better and faster. I think the one he try did a better job then Keith using it had a longer extension on it. That also could be the psi on pressure washer
@@davidhoward2237 Yes, he has a Dewalt version, and it seemed to do a much better job than what Keith's did. He also had issues with the wrong sand on both of the systems. He first tried a fine sand and it didn't work, then he ended up buying super-sacks of pool filter sand, which did work. I think he was using granite particles for the dewalt at one point. I don't remember him doing anything with these inside the boat, as he used Rust Doctor to convert everything, then painted over it.

A little less aggressive wet blaster from a HF cabinet, good form small parts and finishing. I built this hydro blaster from a HF sand cabinet and a cheap sump pump. Its uses a plastic storage tub to catch the slurry. You use a different tub for each size media, siphon off the water and let it dry out to store. To change the media, drop the pump in a clean bucket of water rinse out the cabinet swap out the tub.takes 2-3 minutes. Also does dry blasting also, The modification of the media pick up allows you to vary the amount of media from a pencil lead steam to a full tube. The brass pipe is threaded, unscrew the bolt and changes the vacuum at the bottom. Will work with a couple cups of sand or a single box of baking soda. Yours might be modified but you can built this easy. This wet side is amazing on aluminum

#55 grit from Metromont Materials is about $5 /50# bag I just bought 10 bags last week.
The sandblaster head does have a venturi but is an eductor a water-eductor.
I have the same blaster setup. My pressure washer is 3500psi at 3.5GPM and that's really not enough to drive this gun. They say you need about minimum of 4GPM and 6 is best.
I have the same set up and glass works 10times better
'glass' as in 'glass bead,' or crushed glass?
Crushed glass
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.
Late to the party as usual. Keith, what are the specs on your pressure washer GPM and PSI. Thanks. This looks really useful.
Tsc sells blasting sand and aggregates
Currently unavailable.
We don't know when or if this item will be back in stock.
Pretty sure it will do this but... will it work with crushed walnuts?
i like how at 8:03 the dog starts licking his nuts. if nothing else, this is great salesmanship , I will buy the product from Amazon. your dog is a great salesman.
Hi Shaggy, at licking their nuts or being a great salesman?
Why did you notice the dog licking his nuts?
Ahh, you're just jealous....
First thing I noticed.
You know why that dog is doing that??? Because He Can!
Perfect timeline Keith..... Just in time for lunch.
Neat find, as a frame of reference what are the specs of your power washer unit?
He mentioned that in I think the last video where he first showed this device, but I don't recall exactly what he said. I think it was from Lowes and maybe 4500 PSI, but I don't recall the flow. You could probably find that in the video pretty quick.
