The DUROCK Tile Membrane Adhesive works in conjunction during installations with the Tile Membrane, a popular alternative to traditional backerboard for residential and light commercial work. The system creates a crack-isolation system that will keep minor cracks from spreading through to the tile or grout. Membranes are available in 280 square foot roll; the adhesive arrives in a two-gallon pail and can be easily applied with a roller or trowel.
