Why does the wall tile fall off?

Wall tiles can fall off for several reasons, including:

1. Poor Surface Preparation: If the wall surface is not properly prepared before tiling, such as being uneven, dirty, or not primed adequately, the adhesive or mortar may not bond effectively, leading to tiles coming loose.
2. Incorrect Adhesive or Mortar: Using the wrong type of adhesive or mortar for the specific tile material or substrate surface can result in poor adhesion and eventual tile failure.
3. Inadequate Coverage: Insufficient coverage of adhesive or mortar on the back of the tile or the wall surface can lead to weak bonding and eventual detachment of the tile.
4. Water Damage: Water infiltration behind the tiles due to leaks or moisture seepage can weaken the adhesive or mortar over time, causing the tiles to loosen and fall off.
5. Structural Movement: If the wall experiences structural movement, such as settling or vibrations, it can cause the tiles to detach from the surface over time.
6. Poor Workmanship: Improper installation techniques, such as incorrect tile spacing, uneven application of adhesive or mortar, or inadequate curing time, can contribute to tile failure.
7. Low-Quality Materials: Substandard adhesive, mortar, or tiles themselves may not provide the necessary durability and adhesion for long-term use.

To prevent tiles from falling off, it’s essential to ensure proper surface preparation, use the correct adhesive or mortar for the specific application, achieve adequate coverage, address any water damage or structural issues, employ proper installation techniques, and use high-quality materials. Regular maintenance and inspection can also help identify and address potential issues before they lead to tile failure.
