The standards found in the ANSI (American National Standards Institute) A108.02 document provide the installation method standards used to provide a good looking and long-lasting tile project. When they are followed, the job is headed for success, but when they are not followed, it may be doomed from the beginning.
The tile industry has established installation standards in the American National Standards Institute (ANSI) documents to guide all involved: the design professional, the general contractor and the tile installer.
There are many factors that contribute to the ability of a tile to permanently bond to the substrate, including substrate preparation, proper selection of setting material, environmental conditions during installation, application of bonding mortar and embedment of the tile.
