What is an essential practice before starting a tile installation in areas prone to moisture?

Performing moisture testing is a crucial practice before starting tile installation in areas prone to moisture because it helps identify the presence and level of moisture in the substrate. High moisture content can lead to issues such as mold growth, tile adhesive failure, or efflorescence, which can compromise the integrity of the installation and result in costly repairs or replacements. By conducting moisture testing, installers can determine if the area is suitable for tile installation and make necessary adjustments, such as using moisture barriers or selecting appropriate adhesives designed for high-moisture environments. This step is vital for ensuring long-lasting and effective tile installations in moisture-prone areas.

Other practices, while beneficial in their own right, do not directly address the moisture concerns that could jeopardize the installation’s durability and performance.
