Prova - FLEX uncoupling membrane roll - 3' 3" x 82' (269 ft²)

PROVA-FLEX® is a durable, lightweight tile underlayment that prevents cracking in concrete slabs and is an easy-to-install, less labor-intensive alternative to backer boards over wood underlayment.

• Features a patented Shear Stress Control® system with a non-woven anchor layer to neutralize tension caused by subfloor movement.
• The mesh on top ensures a superior mechanical bond with the hardened mortar that secures the tiles to the PROVA-FLEX®, while the bottom layer neutralizes the tension caused by the movement of the lateral substrate in all directions, protecting the tile surface.
• Eliminates cracks in tiles
• Premium quality, quick-setting mortar required for installation
