What substrate is recommended for tile installation in wet areas such as showers?
Answer: Cement board or an uncoupling membrane
Cement board or uncoupling membranes are required in wet areas because they are moisture-resistant and dimensionally stable, providing a substrate that will not swell, rot, or flex under tile.
What does ANSI A108 specify?
Answer: Standard specifications for the installation of ceramic tile including substrate and method requirements
ANSI A108 is the American National Standard Specifications for the Installation of Ceramic Tile, covering substrate preparation, installation methods, and performance requirements.
What minimum mortar coverage is required beneath floor tile per ANSI standards?
Answer: 80 percent
ANSI standards require a minimum of 80 percent mortar coverage under floor tile to ensure adequate adhesion and no hollow voids that could lead to cracking.
What is a Schluter strip or similar metal edge profile used for?
Answer: Transitioning between tile and other flooring types or protecting exposed tile edges
Schluter strips and similar metal profiles are used at tile edges and floor transitions to protect the vulnerable tile edge from chipping and provide a clean finished transition between materials.
What causes efflorescence on tile grout?
Answer: Water-soluble salts migrating through the grout and depositing on the surface as water evaporates
Efflorescence appears as a white powdery deposit when water migrates through the grout, dissolves soluble salts in the substrate or mortar, and deposits them on the surface as the water evaporates.
When should grout sealer be applied after a tile installation?
Answer: After grout has fully cured typically 72 hours on a clean dry surface
Grout sealer must be applied after the grout has completely cured, typically 72 hours minimum, on a clean dry surface so the sealer can penetrate the grout rather than sitting on top.
