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 re-coat, 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.
