Product Description:

PROVA Flex uncoupling membrane is an ideal underlayment for wet areas such as bathroom and kitchen floors. It provides uncoupling, waterproofing, and crack-in-the-floor preventing properties. The membrane is designed to deliver efficiency, durability, ease of use, and high performance for projects of all scopes. PROVA Flex waterproof flooring underlayment is manufactured from polypropylene, which is impermeable to liquid.

It is a durable, lightweight, and chemically resistant underfloor underlayment that allows for easy tile installation and labor-saving performance. It is a crack isolating solution in floor mat form, protecting floor tiles and other finished surfaces by helping prevent potential damage and reducing grout stress caused by substrate movement. The tile underlayment membrane features an innovative Shear Stress Control mechanism combined with a non-woven anchoring fleece.

This combination effectively counteracts stress resulting from in-plane substrate movement and supports long-term tile performance. This floor mat also offers waterproofing capabilities and vapor management, helping protect floors against environmental moisture. The underside design includes open-air channels that allow moisture vapor to dissipate beneath the tile assembly.

This product performs well in direct interior residential and commercial in-floor tile applications using cement-based adhesive or thin-set mortar adhesive. It works with a wide variety of surface finishes, including bathroom tile, kitchen tile, linoleum tiles, vinyl flooring, ceramic tiles, porcelain tiles, cement tiles, marble tile, stone tiles, granite tile, concrete blocks, and carpet tiles.

PROVA Flex acts as an uncoupling membrane over suitable substrates such as concrete blocks, oriented strand board, plywood sheets, cement slabs, and drywall when installed in accordance with manufacturer guidelines. The membrane can be easily cut with a utility knife, is easy to install, and is ready to tile immediately after installation.

Prova Flex-Heat uncoupling membrane is ideal for use in residential and commercial installations, including bathroom floors, kitchen tile flooring, basement floors, entryways, and renovation projects over existing substrates. It is also suitable for living rooms, dining rooms, bedrooms, hallways, and foyers.

It is a reliable solution for home renovation projects, bathroom decor upgrades, kitchen decor improvements, and overall home decor applications. This uncoupling membrane is suitable for both professional installations and DIY projects.
