The Scotch-Brite Surface Preparation Pad (SPP) removes floor finish using only a neutral cleaner or water, no stripping chemicals required. Optimized mineral abrasives leave less hazing and scratching than sanding screens, while high-quality nylon fibers coated with resin and abrasive deliver a consistently aggressive cut. It prepares wood, vinyl tile, sheet vinyl, marble, terrazzo, and concrete floors for refinishing. Use with rotary or automatic floor machines. Sized 13 inches (330 mm), 10 per case.
