This grit impregnated brush is very popular among the floor refinishing professionals, especially in the VCT (vinyl composition tile) and terrazzo industries. It can offer some astounding savings by outlasting some of our most powerful floor stripping pads by over 100 to 1! The 1¾" silicone carbide impregnated (80 grit) nylon bristles are self-replenishing as your brush wears, offering unmatched value because the brush continues to strip like it was new as the bristles wear down. We recommend using a 1.5 HP floor buffer to ensure no undue stress will be put on your machine no matter what type of stripping job you're attempting. Our 20" low speed floor buffing polisher is a great example of this type of machine at an affordable price.
