Notes: 1For on-grade applications, use USG Durock™ RH-100 Moisture Vapor Reducer or an industry recognized moisture
mitigation system over concrete. Moisture mitigation system may not be needed if a vapor retarder is installed below the
concrete slab in accordance to industry specifications and practice (ASTM E1745, ASTM E1993, ASTM E1693) and the MVER value
of the concrete slab is below 5 lbs./1,000 sq. ft./24 hours. 2The adhesive residue must first be tested to make certain it is
non-water-soluble. Any water-soluble adhesive residues must be mechanically removed down to clean concrete. 3Compressive
strengths published herein were achieved under controlled laboratory conditions. Actual field results may differ due to
environmental conditions; inconsistent proportioning of field-applied water and USG Durock™ floor underlayment, as well as
differences in mixing/pumping equipment.
