CAUSES
1. Excessive amount of glue. Smoothen the background and use less glue. DO NOT USE the glue as an adhesive and leveling material at the same time when we have substrates on the substrate.
2. There is a completely non-absorbent substrate.
3. We use the wrong type of glue for the substrate.
4. We have not installed finishing guides.
5. We have very thin glue (use) less water.
6. The substrate to be applied has a lot of moisture.
Skirting board, the surface is usually unnoticed due to its small size during the smoothing process preceding tile laying. This results in excessive use of adhesive on the back of the tile and direct adhesion to the substrate. The glue due to weight drips by entangling the skirting board. Smotify before and on the surfaces of the skirting board. They must also be clean. IMPORTANT is that the amount of adhesive during application should not exceed the width of the tile.
