Aqua Mix Ultra-Solv may be used for interior and exterior applications. It allows vapor transmission and may also be used as a pre-grouting sealer. Coverage: Approximately 400 to 1,500 square feet per coat per gallon, depending on type of stone, porosity and texture of surface, temperature, humidity, and method of application.
