A versatile mat underlayment for setting tile and stone over any acceptable subfloor, EasyMat is 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 and 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).
