UNCOUPLING MEMBRANE INCLUDING A DIMPLED PLASTIC LAYER WITH POLYMERIC COATING

摘要

An improved uncoupling membrane for use between a top coat of mortar and a base coat of mortar. In use, a layer of tile, stone or the like is set in the top coat and the base coat is applied to a substrate surface. The membrane is of the type including a dimpled plastic layer. The dimples define, on one side of the membrane, a plurality of depressions into which the top coat extends in use and, on the other side of the membrane, a plurality of protuberances. The improvement comprises: a polymeric coating overlying the plastic layer and to which said top coat of mortar adheres in use.
