SUBSTRATE
Since TXTR-LITE™ is a water proof veneer consideration must be given to the substrate it is applied to. In some indoor and most outdoor applications expansion/contraction must be the same to prevent delamination. Concrete and masonry substrates must be at least 28 days old. Hydrostatic pressure conditions and vapor transmission cannot exceed 3 lbs. per 1,000 sq. ft. (1,36 kg per 92,9 m2) per 24 hours using a calcium chloride test (reference ASTM)
