StonePro ZOOM Diamond Impregnated Pad 7 Inch – 400 Grit is a chemical-free diamond floor pad for cleaning, light restoration, and maintenance of marble, travertine, limestone, terrazzo, and polished concrete. It works with water on low-speed swing machines and automatic scrubbers.

Use: 400 grit provides aggressive cleaning and honing, removes light scratches and surface damage, and leaves a clean matte finish. Clear debris and coatings from the surface, mount the pad with the ZOOM logo facing the pad driver, use with water, and rinse the pad after use.
