What potential complications can arise from improper moisture levels before tile installation?

Improper moisture levels before tile installation can lead to significant complications, particularly in terms of mold growth and bond failure. Adequate moisture control is crucial because excess moisture in the substrate can create an ideal environment for mold, which can develop both under the tile itself and in surrounding areas. This not only poses health hazards but also compromises the integrity of the installation.

Furthermore, if the moisture levels are not well managed, the bond between the tile and the substrate can be adversely affected. The adhesive used in tile installation requires specific moisture content for optimal curing and adhesion. Excessive moisture can weaken this bond, leading to tiles becoming loose or even separating from the substrate over time. Proper preparation and monitoring of moisture levels are essential steps in ensuring a durable and long-lasting tile installation, making this answer the most appropriate choice.
