ProVa Flex is a polypropylene membrane used as an underlayment for ceramic tiles and natural stone. It acts as an uncoupling membrane on all substrates and as a water vapor pressure equalization membrane against dampness in the substrate. ProVa Flex protects against movement and stresses found in the substrate and is ready to tile immediately after installation.
ProVa Flex has a fleecing fabric membrane on the bottom that allows for superior bond with thinset and also acts as the separation layer if there is movement in your substrate. ProVa Flex is 1/8" thick and installed using a 1/4" x 1/4" square notched trowel. ProVa Flex is installed using a modified thinset mortar.
