AQUAMIX SEALERS CHOICE GOLD is a premium, no-sheen, natural-look, water-based penetrating sealer formulated to provide maximum stain protection, especially in food preparation and serving areas. The NEW Rapid Cure Formula protects in less than 4 hours and is designed to achieve optimal penetration into dense, low-porosity surfaces. May also be used as a pre-grouting sealer over clean stone surfaces a minimum of 1 hour prior to grouting. Allows moisture vapor transmission. It is also an excellent grout sealer. Uses: Use on all natural stone (such as marble, granite, slate, travertine, and limestone), porcelain, quarry, saltillo, terra cotta, cement pavers, masonry surfaces, and other porous tile and grout where a natural look is desired. Effective for interior and exterior applications. Coverage: Approximately 300 to 1,500 sq. ft. per coat per gallon, depending on type of stone, porosity and texture of surface, temperature, humidity and method of application. Expected Wear: Will vary depending on hardness and texture of surface, type of area, surface wear, frequency and type of maintenance products used. Expected wear is up to 15 years. Extreme weather conditions, harsh cleaning methods and high-alkaline or solvent-based cleaners will affect wear.
