ProVa-Flex is a multi-functional polypropylene membrane used as an underlay for ceramic tiles and natural stone. It acts as an "uncoupling" membrane on all suitable substrates and as a water vapor pressure equalization membrane against dampness in the substrate. ProVa Flex protects against dampness in the substrate and is ready to tile immediately after installation.It is also Made in North America. This is designed to be used with Modified Thinset Scroll down the page to see an explanation between the two thinsets.

What is latex-modified thinset?





The ProVa- Flex is sandwiched between a white polypropylene non woven fabric on the underside to maximize bonding to the subfoor. It also has an interwoven polypropylene netting material (mesh) adhered to the top surface to provide mechanical bonding properties as well as enhancing the surface of contact with Modified mortars used.
ProVa-Flex forms an uncoupling, waterproofing, and vapor pressure equalization layer.
Designed for ceramic tile and dimension stone installations. The overlaying mesh provides a stronger bond than Ditra and does not require the purchase of Ditra XL ProvaFlex serves as an uncoupling layer for problematic substrates, a waterproofing membrane, and a vapor pressure equalization layer to accommodate moisture occurring at the underside of the substrate. To bond ProVa-Flex , use a Modified mortar that is appropriate for the substrate. Apply the Modified mortar using a 1/4" x 3/16" (6 mm x 4.5 mm) V-notched trowel. The anchoring polypropylene non woven fabric on the underside of ProVa-Flex must be fully engaged in the mortar to provide a mechanical bond to the substrate. Using the thin-bed method, set the tile covering directly on the ProvaFlex in such a way that the tile adhesive becomes mechanically anchored in the routered mesh covered cavities of the ProVa-Flex matting.
ProVa-Flex has a 25 year warranty The Life expectancy of ProVa-Flex will exceed 150 years.
