AQUA MIX STONE ENHANCER is an excellent, no-sheen, enhanced-look penetrating sealer formulated to darken and highlight the character and beauty of unsealed natural stone. It rejuvenates the color and improves the appearance of worn and weathered stone. May also be used as a pre-grouting sealer. Allows moisture-vapor transmission. It also effectively seals and darkens the color of grout joints. Uses: Recommended for use low-porosity natural stone such as marble and granite, dense slate, dense limestone and dense flagstone. 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 3 years. Expect exterior applications to require more frequent re-applications. Weather conditions, harsh cleaning methods and high-alkaline or solvent-based cleaners will affect wear. Coverage: Approximately 500 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.
