Scotch-Brite Diamond Floor Brush 3000 Series is designed to clean and polish uncoated concrete, terrazzo and potentially other stone floors in one step. Brush 3000 is a finer grit brush intended for daily use on floors where medium to high 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.
