SUBFLOOR MATERIALS
For new installations TXTR-LITE™ is best adhered over most standard subfloor materials such as cement board, and backer board usually in the ½" to ¼" thickness range. Using a layer of cement board or backer board over wood floors will result in a more solid feel to the finished floor.
TXTR-LITE™ will also offer a protective resilient surface inherent with the stone face and fiberglass backing. This can further help with crack prevention in some cases.
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)
