How can moisture issues affect tile installation?

Moisture issues can significantly impact tile installation, primarily because excess moisture can weaken the adherence of tiles to the substrate. When moisture seeps into the adhesive or under the tiles, it can lead to a breakdown of the bonding agents. This compromises the integrity of the installation, resulting in tiles lifting, which can create uneven surfaces and may lead to further damage over time.

Additionally, moisture can infiltrate the grout lines, causing them to crack. When grout experiences fluctuations in moisture levels, it expands and contracts, which eventually leads to deterioration. Such conditions can also facilitate mold growth and create overall instability within the tiled surface. Proper management of moisture is thus critical in ensuring a successful and long-lasting tile installation.
