What can happen if tiles are installed over a wet surface?

• A. Increased adhesive strength
• B. Poor adhesion and potential mold growth
• C. Decreased installation time
• D. Improved tile alignment

Answer: (B)

Installing tiles over a wet surface can lead to poor adhesion of the tiles to the substrate. Moisture can interfere with the bond between the adhesive and the tiles, causing them to lose their grip. This can result in tiles becoming loose over time, leading to cracks or even complete detachment. Furthermore, excess moisture trapped beneath the tiles can create an environment conducive to mold growth. Mold not only poses health risks but can also cause further damage to the adhesive and the substrate, leading to costly repairs and maintenance. The correct choice captures the significant risks associated with tile installation inappropriately conducted on wet surfaces, highlighting the importance of ensuring the substrate is dry to achieve a durable and long-lasting installation.
