Due to its porous nature, natural stone acid-etches and stains without protection. Industry leaders report that sealers and other coatings are short-term fixes and that natural stone, such as marble, will begin to look stained, etched or damaged from water, wine, and food within hours or days after application. Clearstone Coating is the only long-term natural stone protection product on the market for both commercial and residential application with over 21 years of proven performance and excellence that stops acid-etching and staining. Our 10-year manufacturer’s warranty against etching and staining protects your investment for years to come as no other product stands by their commitment to excellence like Clearstone.
