Scotch-Brite Diamond Floor Brush 1000 Series is designed to clean and polish uncoated concrete, terrazzo and potentially other stone floors in one step. Brush 1000 is a coarser grit brush intended for daily use on floors where low gloss is desired. It is conformable, allowing the flexible bristles to reach low spots on the floor while minimizing debris clogging. No assembly or pre-soaking is required and it is easy to install on standard, low-speed equipment
