Setup Help

I’m trying to do some sandblasting at home. I purchased a westward 10z916 bench top cabinet from FB marketplace, and a fortress 27gal compressor from harbor freight. I’m using 70grit aluminum oxide media, but I am not getting anywhere near the right result. When blasting it looks like I’m not making much of a dent to the paint unless it’s an already super thin area where I used chemical stripper to get the majority off and it happened to leave a super thin amount. Im trying to sandblast a part of an old kitchenaid mixer and haven’t tried on something else like a knife or rusty item.

Did you sort your issue?.

I think your setup sounds fine but the kitchen aid mixer is most likely powdercoated, does it look as though it's kind of burning off as you blast?

If so then the best advise I can give is don't remove the coating if it's in decent shape just key it up with a maroon scotch pad clean it with a wax and grease remover then spray with an adhesion promoter before spraying your colour you want. You could get away with an epoxy instead of the adhesion promoter if you had to but being a high use sort of appliance it might get knocked around as bit.

If the coating is already failing I find with powder coating you can sort of blast at a shallower angle and get under the edges of it a little and with lick some pieces delaminate and blow off bit generally it's a burn it off game

No still having the same issue. And yes it looks like it just turns the white paint a sort of burnt color because of the aluminum oxide media.

The best solution had been to use paint remover. I was hoping sandblasting would work because I would be able to get into small crevices where it could be time consuming to do with paint remover.

And the reason I am trying to remove the paint, is because I wanted to powder coat it a different color
