  • RedGard® Uncoupling Mat


  • A waterproof, vapor-proof uncoupling membrane that can be used for crack-isolation in most tile, porcelain or natural stone installations, and can be applied over challenging substrates such as installation over green (young) concrete and single ply 19.2" (49 cm) o.c. wood framed floors. RedGard® Uncoupling Mat is designed differently than bonded membranes. When exposed to excessive substrate movement it absorbs stress and preserves the surface and integrity of the tile. RedGard® Uncoupling Mat's bonding layers have reinforced fleece which locks mortar into the mat, ensuring strong, reliable installations.

  • EasyMat® Tile & Stone Underlayment


  • A versatile mat underlayment for setting tile and stone over any acceptable subfloor. EasyMat® is so fast and easy to install because it is up to 25 times lighter than 1/4" (6 mm) backerboard, cuts easily with a utility knife, doesn't require any nails or screws, and comes in a peel & stick version. The mat was specially designed so that the mortar locks in, creating a bonded crack-prevention system for subfloor movement up to 1/4" (6 mm). This bonded system will withstand repeated stress and still maintain its tenacious bond. It is a superior alternative to cork underlayments because it will not rot, shrink, or absorb water. EasyMat® has SoundGard® Technology and therefore offers high and credible impact sound reduction. Use EasyMat® with other Custom® materials to qualify for a lifetime warranty.
