Our most popular grit impregnated brush! This aggressive brush is used for extreme scrubbing and stripping finishes from hard surfaces. With the 1.75" length bristles, this grit brush effectively cleans wide grout lines. The silicon carbide impregnated nylon bristles are self-replenishing as the brush wears. Meaning as they wear down, they will not lose any of their effectiveness in removing those heavy soils. This offers unmatched value that outlasts our 17" floor stripping pads over 100 to one! All of our grit impregnated brushes can be found in our rotary floor buffer brushes category, and must be run in a wet environment.
