STRATA_MAT™ XT is designed specifically for ceramic tile and dimension stone installations serving as an uncoupling layer and vapor management layer that accommodates moisture from beneath the tile covering. STRATA_MAT XT performs all these functions while still providing the requisite support/load distribution for the tile and stone covering. At 5/16" (7.9 mm) thick STRATA_MAT XT helps to creates an even transition between typical ¼" to 3/8" (3 to 9 mm) thick tile and 3/4" (19 mm) thick hardwood flooring. STRATA_MAT XT will provide a faster drying of the mortar, allowing for a shorter time to grout when using both modified or unmodified mortars allowing you to use the appropriate mortar for the installation.
