PROVA FLEX 3.28 Ft. W x 16.5 Ft. L Tile & Stone Underlayment, 54 Sq. Ft./Roll Brand_MasterSeal and for stimulating root developmentA lightweight underlayment designed for tile installations over wood and concrete substrates. ProVa Flex uncouples the floor covering from the substrate and prevents the transfer of stresses to the tiled surface. Thus, a crack caused by movement in the substrate is neutralized. Cracks in the substrate are bridged and not transferred to the floor covering.
