The Scotchgard™ Stone Floor Protector is a high performance floor surface hardener. Just two coats produce a clean, shiny, durable finish that is less susceptible to scuffs, black marks, stains and scratches. It is ideally suited for concrete, marble, terrazzo, and other porous stone surfaces. It produces a glossy, very hard, dust repellent, chemical-resistant and watertight surface. This protectant surface is easy to repair or recoat, with no stripping required. When scratches do occur on the surface, it can be repaired by burnishing with Scotch-Brite™ Purple Diamond Floor Pad Plus.
