What is a common issue that can occur if tiles are not set properly?

Cracking or loosening of tiles is a common issue that can arise when tiles are not set properly. The integrity of a tile installation depends significantly on the even application of the adhesive, the right amount of grout, and correctly aligning the tiles. If tiles are set unevenly, or if there isn't adequate support beneath them, stress can build up within the tiles as they expand and contract with temperature changes. This stress may lead to cracks forming in the tiles themselves or cause them to loosen from the substrate, potentially leading to further damage and the need for repairs. Proper installation according to standards minimizes the risk of such issues, ensuring longevity and durability.
