Re: Repairing Sandblast Damage

Excellent article. If you want NO warpage use a pressure washer (minimum pressure of 2800 and 2.5 gpm) and an attachment from water and use the abrasive of choice. The abrasive is drawn into a special end on the wand like a paint gun draws paint up from the cup (venturi principle) and cleans rust like you wouldn't believe. It can't warp because the water keeps it cool. Would you rather blast with air at 100-150 psi and warp it, or blast with 2800 psi with water and NOT warp it???? Been there done that, never going back to 100-150 psi system again. Look up on youtube under wet sandblasting.
