A friend of mine has one of these on loan for the summer so I borrowed it for a couple weeks. I hooked it up to my Craftsman 3200 PSI pressure washer and have been using it to sandblast my frame outside. So far it has been pretty awesome and I would highly recommend it. We bought two 50 lb bags of Quickrete play sand from Lowe's and managed to do about 50% of the frame so far in two sessions of about an hour each Here's a video: Dropbox - Video Jun 11, 4 59 05 PM.mov - Simplify your life I'm set up in a carport to keep the spray from leaving the zone I'm in, and wearing safety glasses, a face shield, disposable clothes, and a N100 respirator. My friend says I'm being overly cautious about silica dust hazard since it's wet blasting. I wrote Typhooon to ask them what they think about the hazards of blasting with play sand, but no reply yet. Wondering what you guys think? Am I being overly cautious? What about cleanup afterwards when I am done and tear everything down? I'd hate to have to worry about fine silica dust in the yard for the dog/wife/kid. My plan was to wet everything down afterwards and either turn the soil over or haul it out to the dump.
