Black Stripper Pad 7200 maintains consistent high performance throughout the life of the pad while it removes finish, sealer and contaminants from the floor surface. Use with water-based, floor finish-stripping solutions to remove old, soiled, floor finishes and sealers. Uniform distribution of mineral abrasives throughout pad - not just on the surface - delivers impressive performance and a long, useful life. Pad is made of nylon and polyester fibers in an open, textured nonwoven construction. Individually separated and coated fibers help produce more consistent results. This standard stripper pad is designed for use with rotary or automatic machine speeds of 175 to 600 RPM.
