The new TCA handbook informs us that the American National Standards Institute (ANSI) A108 Committee on Ceramic Tile has revised the A108, A118 and A136 designations for the installation of ceramic tile.
In addition to these revisions, the committee has approved new specifications for: the installation of ceramic tile with exterior glue plywood (EGP) latex Portland cement mortar; installation of load-bearing bonded waterproof membranes for thinset ceramic tile and dimensional stone; standard cement grouts and polymer-modified cement grouts; and EGP latex Portland cement mortar.
