any links ? never heard of an attachment for sand/pressure washer .

 

:loco: HUH?

 

My reaction exactly!

 

would be interesting to get feedback on these
i did a google search and they are out there,,, sad,, its the first ive heard of them

 

Anybody ever use the attachment for this? I can see where this might be nice for keeping the sand and dust down but before I buy one I'd like to know what is the downside.

There is all sorts of them out there. Here's one. Wet Sandblast Kit | Princess Auto

 

I used one years ago clean a concrete floor before we epoxied it. Work well for that . not so sure I would use on a car, if you do use it on a car you'd have to dry it ASAP i would think.

 

Parts too big for my cabinet, not the car.

 

here is a review on the one from princess auto
princess auto is Canada's habour frieght

I had a 2600 psi & 2.6 gpm washer which just didn't work with the sand blast kit as it states in the description that it needs a minimum of 2600 psi & 3 gpm. I went to PA and bought the 13hp honda w/3600 psi & 4 gpm and now I'm in business. Make sure you use 100% dried sand or it'll clog up very quickly. I had some chromed plated parts that I wanted to strip down and this kit blasted it right off. Both parts are about a sq foot each and I blasted them down to bare metal in all of 20 seconds.

 

I just checked the details on the PA device and it says the min. pressure is 1500 psi. Has that changed since you got yours. If so it might be ok with my 2500 psi. machine.

 

I thought it was preferable to keep moisture out of air lines so it doesn't clump up the sand and clog things up...but now we're adding a bunch of water and sand together?

 

Actually the new hotness is wet blasting called "Dustless" sandblasting, it keeps heat out of the equation and also eliminates dust. Using a pressure washer may not be the best way to get er done, but who knows.

I have been seeing a bunch of adds and promotion on the Saturday morning car shows on TV for this stuff.

Pressure washer does the same thing, just on a smaller scale. Check the video on the Northern Tools web site. Unfortunutly when 69Canuck mentioned his pressure problem I looked at the specs for the Northern and it takes even more pressure, 3500 psi. My washer is only 2500 so I guess I'll pass.

Thanks for the replies.

 

I could have used an attachment like that a mere hundreds of times....

 

Was thinking of building one after I saw it at Princess. It sure couldn't hurt trying to strip parts.

Putz: The flash rust that will happen isn't that big of a deal. You could wipe/sand it off or just epoxy over it.

 

It works great on concrete, aluminum, or any non-ferrous material.

Anything with carbon starts rusting seconds after you move to the next area and air hits it.

 

#1 thing i hate about sandblasting is the dust and mess .
looks interesting , i might get one . yes it will surface rust almost instantly but a quick buzz with a DA sander and 80 grit will fix that .

 

Let us know how it works if you do. I'm not 100% convinced it will draw enough (evenly, especially) to blast away rust.. But if it does, seems like the best way to strip rust in the summer!

 

I think we all know that steel will rust in the presents of water.

 

I think you're overestimating a few minutes of water vs 50 years of salt and water. A little flash rust never hurt anybody.

 

When I yanked the filthy engine out of my car, I taped all the ports that were open Shot it with oven cleaner, let it sit for a moment then used the pressure washer on it. It did a fine job getting bulk grease off the entire engine and made the detail cleaning a lot easier. After I finished, I used the leaf blower to dry the whole thing. The bare steel on my valve covers never got a touch of rust. The only other place that I pressure washed on the car was the underbody where the engine and transmission oil undercoated the car. In that case, I still had all the old paint/primer and it was not washed away.

 

The water blasters I've seen advertised on TV are CRAZY expensive; might be practical for a professional shop, but certainly not for a home shop.

Now, if a small scale version that adapts to a home pressure washer actually works, that would be REALLY cool!

I think this thread started with that.

 

I googled wet stripping , wow got sidetracked for hours !!!

 

i see what you did there!}:|

 

A sandblast pot with pressure washer attachment does the same thing as dustless. You have more flexibility with the pressure washer and seperate pot, You can use both independently of each other, where the dustless system always needs water mixed with aggregate. I recently demo'd the pressure washer setup, in my area it seems to be primarily used by flooring contractors. Either way it makes a mess.
