Key provisions of the installation standard To develop ANSI A108.19 Interior Installation of Gauged Porcelain Tiles and Gauged Porcelain Tile Panels/Slabs by the Thin-Bed Method bonded with Modified Dry-Set Cement Mortar or Improved Modified Dry-Set Cement Mortar, a group of install- ers, architects, and manufactur- ers conducted countless experi- ments to discover application and embedding techniques that make possible maximum mortar cover- age, particularly for tile panels/ slabs. Through these experiments, standard setting procedures for gauged porcelain tiles and tile panels/slabs were developed that facilitate optimal workmanship and system integrity. Mortar application: It was deter- mined that applying a layer of mor- tar to both the back of the panel/ slab and the substrate would result in the necessary bond coat thick- ness of 3/16” (4.8mm) and would allow for full encapsulation of lip- page control systems. Anything less than this method would result in an embedded mortar layer thickness that was insufficient to achieve the agreed-upon substrate tolerance of a maximum deviation of 1/8” in 10 horizontal feet (3mm in 3m) from the required plane when measured from the high points in the surface for floors.
