I would like suggestions for removing overspray from concrete. I recently painted a truck for some one with a very dark gray metallic. This truck was completely disassembled and painted inside and out for a complete color change. In the past I have had no real problems just sweeping and power washing my floor to remove overspray. However this paint has more bite to the concrete. I have tried liquid paint stripper in a couple of areas and it worked well but my shop area is about 1600 sq ft. It is not practical to apply this by hand and scrub the whole floor. The floor is not completely covered but I want an even appearance when I finish. Would muriatic acid properly diluted and applied with a yard sprayer work to clean my floor?
