PROVA FLEX 3.28 Ft. W x 16.5 Ft. L Tile & Stone Underlayment, 54 Sq. Ft./Roll Brand_MasterSeal Nutrient Guaranteed Units Crude ProteinA lightweight underlayment designed for tile installations over wood and concrete substrates.

Cracks in the substrate are bridged and not transferred to the floor covering.
