Tominator Posted January 19, 2012 Report Share Posted January 19, 2012 Anyone ever do any sandblasting? Suggestions on the media to use? Regular play box sand is a no-no from what I understand because of the silicon that gets airborn. Quote Link to comment Share on other sites More sharing options...
Mystery Hunter Posted January 19, 2012 Report Share Posted January 19, 2012 (edited) It depends on what I am Blasting. I have a large bead Blasting Cabinet I use glass beads in and a Pot blaster that I use use Blasting Sand in for larger jobs like Trailers or machinery. The Blasting sand comes in different coarse sands for rough or finish blasting. I never use Sand Box Sand as it will cloag up your Gun and is not a consistant size. You can also use walnut shell media that comes in different coarses. I love my Glass bead blaster Cabinet for smaller projects like, Rifle barrels, Rifle parts and anything I want to blast up to about a 30" X 30" Size. Love the glass beads!

LETMGROW Posted January 20, 2012 Report Share Posted January 20, 2012 We don't use play sand either for the same reasons. We use sand made for sandblasting. We have a large Scat Blast cabinet with glass beads. We don't use glass beads on aluminum though. It will actually impregnate itself into the parts and can totally ruin an engine. Soda blasting is acceptable as it is not course, leaves a smooth surface and is bio-degradeable. Everything has its place. Play sand belongs in a sand box to play in.

Do not use the glass beads on Aluminum. I also use the soda blasting for that! Quote Link to comment Share on other sites More sharing options...
Tominator Posted January 20, 2012 Author Report Share Posted January 20, 2012 This will be on sheet metal. Quote Link to comment Share on other sites More sharing options...
Mystery Hunter Posted January 20, 2012 Report Share Posted January 20, 2012 Is the sheet metal rusted or are you just trying to prep it before priming and painting? For Rusted medal use a Meduim or Coarse blasting sand depending on the amount of rust. If only prep is needed just use a fine Sand. If taking off old paint go with a Meduim sand and then go back over it with a fine sand to prime and paint! Hope that helps!! Quote Link to comment Share on other sites More sharing options...
LETMGROW Posted January 20, 2012 Report Share Posted January 20, 2012 You will also want to be careful how much pressure you are using on sheet metal. You can actually heat the metal enough to the point where it will warp or deform the metal. Don't force the job. Lynn Quote Link to comment Share on other sites More sharing options...
