Generally, ceramic tile adhesives need to be selected according to the application environment and ceramic tile types.

The amount of tile adhesive is insufficient, and full adhesion cannot be formed after paving.
The ceramic tile adhesive is not stirred evenly or not stirred as required, such as adding cement, which causes the ceramic tile adhesive to have unstable performance, and is easy to cause weak adhesion, forming hollowing or falling off.
After the tile adhesive combs the stripes, the tiles are not paved in place in time.
No protective measures are taken when the ambient temperature is too high or too low, or the material temperature is too high or too low and the construction is forced.

Although the quality of existing ceramic tile adhesive products has been very stable, we still occasionally encounter tile hollowing and falling off during construction.

For the base surface easy to generate vibration, if the tiles are knocked too hard with a rubber hammer after paving, the tiles will become loose.
Only the right products can ensure the paving quality.

If the light partition wall is deformed, it is easy to have the problem of brick falling and hollowing.

2.
Tiles are directly laid on the expansion joints of the base surface, and the tiles fall off due to the expansion of the base surface structure.
The base surface is not leveled, and the thickness of the tile adhesive is uneven, resulting in a large non-uniformity of shrinkage caused by the drying process of the tile adhesive, which causes local hollowing.
The rigidity of the base surface cannot meet the requirements of ceramic tile installation.
For ceramic tiles with low water absorption or large size such as vitrified tiles, high-performance ceramic tile adhesive must be selected.
3.
The coating thickness of ceramic tile adhesive is too large, resulting in large shrinkage in the drying process of ceramic tile adhesive, forming hollowing.

The opening time of the tile adhesive has passed, causing hollowing and falling off.
Improper selection of tile adhesive.
The finished surface was not effectively protected during curing, and the tiles were subjected to pressure, impact and external force vibration during curing.
The welfare is coming.

Through analysis and summary, we should avoid the following behaviors in the paving process.
The tiles were not rubbed and pressed after paving, resulting in no effective bonding.
The back of ceramic tile or stone is not cleaned, and there are dust or release agent and other substances that affect the bonding strength.
