Hey guys, its been a while since I've posted here, been really busy (guess that's a good thing). Im really interested in possible buying a shot blaster, possibly the Blastrac 1-8dm, for getting floors ready for SLU/ Moisture control systems/ and even painting floors. I've never used one before and I'll probably rent one next week to test it out on my sisters porch and garage, its concrete and has paint on it, but it shows the cup wheel marks from the grinder on the porch. Its uneven has dips and hills, would shot blasting remove the latex paint and leave a smooth surface in the garage which has not been grinded? The Paint is latex meant for garages, its suppose to be 4mils thick each coat with a max of 2 coats. or is there a better way of removing the paint?
