Wetblasting

[fclaridge]

I recently bought an attachment for my pressure washer to siphon sand and sandblast with water. I got a new pump for my pw and tried it out. Some quirks, but overall I like it. I posted a 1 minute video here:

Let me know what you think.

I am very interested in this. Where did you get the attachment? Can you compare this process with other types of media blasting? What prompted you to try this over other processes?.......Thanks.

How did you rig it? What are you using for a tip? What kind of media are you using? You asked for questions, haha but I am just very curious as to how you **** sand without it getting wet and clogging. I would also be worried about the tip wearing out and how you can control the pattern. All in all it looks very impressive, I for one like it.

I got it online at Northern Tool. Link: http://www.northerntool.com/shop/tools/product_8520_8520
And a link to the replacement nozzle: http://www.northerntool.com/shop/tools/product_37202_37202

Basically attach to your pw wand, put the hose for the sand in a bucket of clean dry sand, I used the play sand from Home Depot. I went through 100# of sand and the tip did not show any signs of wear yet.

For some reason I thought you made it. Looks like a slick set up though and quick too.

Thanks for the video

What are the specs on your pressure washer

 

[fclaridge]

It's an Excell Brand I got from Home Depot. It had the strap type pump on it that gave up last summer. I finally got the new replacement pump made by Giant and it is much better.

Some of the reviews at Northern date back to 2009......I didn't know you could get something like this. Seeing it now, it makes perfect sense. It just seems like a neat way to do some occasional abrasive cleaning without having to go too far into a big set up.

Seems like a good way to clean algae/paint/oil off concrete...

Saw that on TV once, looked like a great thing for doing frames and the like without making a huge cloud of dust.

You could even re-use the abrasive... just do it somewhere on concrete that gets sun, and let it all dry out then sweep it up.

Was it just me, or did it seem a bit slow?

Nope. A grinder and a wire wheel appears to be faster than that.

I bought one too , about 8 years ago .to blast a tractor . I found that putting the sandblast sand level or higher than the nozzel helped with the flow of sand. I set my bags on a barrel and had good results. The higher the GPM of the PW the better too....

I agree if we are talking about a relatively flat surface. I have considered one of these for doing convoluted surfaces and machine restos.

I still think it is a neat contraption with several benefits, but kind of imagined it would be a paint blistering fast paced alternative.
