Problem of Tile debonding
FACTORS TO CONSIDER WHEN TILING IN BATHROOM AND KITCHEN
1. Tiling by applying traditional mortar in lumps at tile back (as shown in the picture) can create voids underneath the tiles, which leads to tile fragility. Moreover water ingress through the voids will damage the nearby areas.
2. The efficiency of tile adhesive will be decreased if using with wrong methods such as applying in lumps, or use with traditional trowel. This will cause tile being dislodged at later stage.
3. Fixing large size tiles with traditional way by using traditional mortar and doing floor leveling at the same time can cause debonding problem and tile breaking at the corners.
