Tile installers who use the American National Standards Institute (ANSI) specifications, the Tile Council of North America (TCNA) Handbook, along with tile industry accepted best practices can confidently install tile of lasting beauty and durability which will stand the test of time.
Unfortunately, the well-meaning tile installer may encounter jobsite situations that do not meet these industry standards. Being asked to complete an installation which is outside industry guidelines is one thing, but agreeing to complete the work is another. In doing so, the installer places him/herself in a precarious situation.
