Prova Protegga Underlayment 269 sq.ft

It acts as an "uncoupling" membrane on all suitable substrates and as a water vapor pressure equalization membrane against dampness in the substrate. Protects against stress transfer to tile. Crack isolation protection.Waterproof and controls vapor penetration. Ready-to-tile immediately. Protegga 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.
