sand blasting with a pressure washer

Dancbtmkr · Jun 19, 2008

I have an H that I'm gonna blast and repaint. First of all, I need to commendeer a sand blaster. My buddy has one, but I don't have a 50 gal compressor to operate it. I have a pressure washer, and I was looking into getting a sand blast "wet blast" attachment for it.

anyone have experience with this? I don't want to waste my money. I just want to do what's cost effective.

Thanks in advance.

Dan Used to work at a truck shop that had pressure washer sand blaster. Worked good only problem was getting metal dry and primed before rust set in. Bernie Steffen

Dan ---

You need to get some new oil seals put in before painting.......

Oven cleaner on that dried oil, before pressure washing....

Forget sand blasting --- sand gets into bearings and oils, that cause problems later...Don

You will want an aircompresser with al least 70lbs and 70 cubic feet per minute to do a good job or it will take a long long time. Should have a portable compresser to do that kind of volume or a large rotary.

what seals are you referring to?

If not sand blasting to prep cast iron metal, then how?

looks like the axle seals leak as well as the gasket or seal at the pto assembly.

Unless you are going to go back with automotive paint I wouldn't bother trying to strip all the old paint off with a sand blaster. Use (rent) a good power washer (3000 PSI or so) to clean things up and peel off any loose paint then lightly sand the old paint (and sand out any surface rust) on the sheet metal. Its stuck to the tractor for 50+ years and makes a good "primer" for the new impliment paint.

The castings need to be clean (especially around your leaking seals) and free of all contaminates the paint will stick them without even sanding (at least in my experiance). Their rough surface aids in the paint adhering.

As mentioned below the sand gets into everything and you're still sanding to stay ahead of the rust.

I saw one of those on one of those car restoration shows. They used it to clean off a chassis. The host admitted it wasn't as good as a real industrial sandblaster, but it's a lot cleaner and safer because the water keeps the dust down. He wasn't wearing anything special except a face shield.

I'd only use it on rusty implements and other things where you're not trying to save the seals.

Thank you for the link. I've been looking for a long time. Gonna get one and use it to clean off my plow for painting.

I can say from firsthand experience a power washer will take paint off most anything. Bring the nozzle up nice and close and make sure you wear goggles.
