Miracle Sealants 511 H2O Plus is a water-based penetrating sealer engineered to provide superior protection for all natural stone, tile, grout, and masonry surfaces. It creates an invisible barrier that resists moisture, stains, salt ion intrusion, alkalis, and freeze/thaw damage, while still allowing moisture vapor to escape. Unlike solvent-based alternatives, it features lower odor and won't alter the natural appearance of the surface, making it ideal for both residential and commercial environments. This versatile formula is suitable for a wide range of substrates including granite, marble, travertine, slate, ceramic and porcelain tile, quartz, cement grout, terrazzo, concrete, stucco, brick, and more. It's perfect for high-traffic areas like kitchens, bathrooms, showers, driveways, garages, patios, and other facility spaces. For enhanced protection on porous stone surfaces, 511 Porous Plus is recommended, while those seeking protection with a color boost should opt for 511 Seal & Enhance.
