Scotch-Brite SPP17 is a 17 in round surface preparation pad built for rotary and automatic floor machines. Nylon fibers coated with resin-bonded mineral abrasives deliver a consistently aggressive cut with less hazing and scratching than sanding screens. Use with neutral cleaner or water alone to strip floor finish and prep wood, vinyl tile, sheet vinyl, marble, terrazzo, and concrete for recoating. Sold 10 pads per case.
