About This Product
Penetrating Protection for Cementitious Grout
Miracle SealantsĀ® 511 Spray-On Grout Sealer is a solvent-based penetrating aerosol sealer designed to protect cementitious grout joints from water, oil, stains, alkalis, salt intrusion, and freeze/thaw damage. The invisible barrier helps preserve grout while allowing moisture vapor to escape, maintaining the natural appearance of the installation.
Fast Application for New and Existing Grout
The convenient directional spray allows the sealer to be applied to freshly installed grout in as little as 2 hours after grouting, or to clean, dry existing grout. Because it penetrates below the surface instead of forming a coating, it will not change the appearance of grout or surrounding tile and stone.
Suitable for Interior and Exterior Installations
511 Spray-On Grout Sealer is recommended for kitchens, bathrooms, showers, backsplashes, patios, pool decks, floors, countertops, entryways, commercial buildings, restaurants, hotels, retail spaces, stadiums, and other residential or commercial grout installations. It is safe for use around ceramic, porcelain, quarry, glazed, and glass tile as well as marble, granite, limestone, travertine, slate, and other natural stone surfaces.
Long-Lasting Weather and Stain Resistance
The penetrating formula provides protection against weathering, UV exposure, acid rain, staining, water, and oil while resisting freeze/thaw damage. The aerosol contains no CFCs and is packaged in a recyclable container for convenient application.
