These pads can be used on a variety of surfaces and substances and are ideal for granite polishing, concrete polishing, marble polishing, terrazzo polishing, engineered stone polishing, travertine polishing, glass polishing and nearly any other kind of hard surface. Ideal for restoration, these diamond polishing tools can be used for floor polishing, counter top polishing, stone sculpture polishing, honing, seaming and repair of areas where machine polishing is impossible or impractical.
