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.
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.
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.
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.
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.
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.
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.
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.
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.
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
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.
@@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.
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".
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 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
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?
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.
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.
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
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.
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.
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?
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.
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...
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
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.
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.
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.
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.
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.
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.
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!!
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.
I have been following your updates and if I have missed a video when did you get the table ground down and finished? I see you have already put it back together. Did I miss something? The last video you were are apart and going to send it out to be grounded down.
The base and table are together. Does that mean he's sending the entire legs and base out to be grounded? OK . That would be a lot easier for shipping. Thanks for the reply
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.
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. ..
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.
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.
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.
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.
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?
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.
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

Another option is let it flash, and hit it with ospho, or another converter and it’ll create a nice barrier as well.
I bet you could mix in a little garnet and shorten the sand supply hose and get a bit more aggressive abrasion

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
Great idea--Thanks for sharing.
Can you use crushed glas in these?
Try paver sand it's just as course but its cheaper then the pool filter sand

He did a video about upgrading his blasting cabinet I think.
Always good Keith thanks for sharing 👍🇦🇺
Looks like the dog enjoyed himself a out 13 min in.
Late to the party as usual. Keith, what are the specs on your pressure washer GPM and PSI. Thanks. This looks really useful.
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.

How did you deal with flash rust?
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.
hi Keith, you forgot to mention the Tidy Cats sand container. They are great for storage. I have a dozen of them.

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.
Is 2600 psi enough for this set up? Thank you
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.
How many bags does it take to do that piece
How many PSI pressure washer did you use?
Dog putting on its own show....lol!
What PSI pressure washer did you use in the video?
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.

Local box stores where I am do not stock the pool sand though, so I'm looking for other media alternatives.
I have the same set up and glass works 10times better
'glass' as in 'glass bead,' or crushed glass?
Crushed glass
I have little doubt this is cheaper than farming it out too.
Any way to control the amount of media at the nozzle Keith ?
Did you change the color?
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.
#55 grit from Metromont Materials is about $5 /50# bag I just bought 10 bags last week.
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?

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
