Thread: water/sand blasting

Tweet

I know of someone personally who used a 4000psi pressure washer with a sand injector and sand blasted a frame. He told me that he used a vinegar/water 50/50 mix brushed right on to the metal to neutralize it. The frame was then coated with POR 15. The benefit of using a pressure washer as a sand blaster would be that the water would keep the metal from building the heat normally generated with sand blasting, plus you dont have all the air borne dust/rust/silicone to deal with. To each their own, but it looks like a win, win to me.

Anytime water and steel meet you have instant rust . Vinegar is great on windows with a 50/50 mix. So if you can get it on a frame before moisture arrives you are a lucky person..

metal does not warp from heat generated by sand. it warps from the peening of the metal by the sand. 4k lbs of pressure with sand will warp metal easy.
