As a key auxiliary material for ceramic tile installation, the correct use of ceramic tile back adhesive directly affects the firmness and service life of the tile installation. When using ceramic tile back adhesive in Shandong, the following precautions must be strictly followed to ensure the construction quality.
Â
Firstly, the construction environment should be controlled. The construction temperature needs to be kept between 5℃ and 35℃. This temperature range can ensure the back adhesive exerts its bonding performance normally. Too low a temperature will slow down the curing speed of the back adhesive, affecting the construction progress and bonding effect; too high a temperature may cause the back adhesive to dry and set too quickly, shortening the effective construction time. At the same time, in sandy and dusty weather, the sand and dust in the air are easy to adhere to the base surface or the surface of the back adhesive, destroying the flatness and sealing of the bonding surface, and leading to problems such as hollowing and falling off of the tiles later. In rainy weather, not only will the base surface be wet, but also the back adhesive will be diluted, reducing its bonding strength. Therefore, construction is not suitable in sandy, dusty or rainy weather.
Â
Secondly, the base surface treatment is crucial. The base surface should be clean, firm and free of impurities such as dust, oil stains and wax. Dust will form an isolation layer between the base surface and the back adhesive, preventing them from combining fully; oil stains are water-repellent, which will affect the wetting and curing of the back adhesive; wax will form a smooth film on the base surface, greatly reducing the adhesion of the back adhesive. If there are these impurities on the base surface, they need to be thoroughly removed with cleaning tools in advance. If necessary, the base surface can be polished to increase its roughness and improve the bonding stability between the back adhesive and the base surface.
Â
Furthermore, the details during the construction process are of great importance. On the one hand, the bonding surface should be kept clean and dry. In addition to avoiding construction in rainy days, tile installation should not be carried out in a humid environment. A humid environment will make it difficult for the moisture in the back adhesive to evaporate, prolong the curing time, and may also cause bubbles inside the cured back adhesive, affecting the bonding quality. Therefore, during construction, it is necessary to keep the environment dry as much as possible, and if necessary, ventilation equipment can be used to accelerate air circulation. On the other hand, no additional water needs to be added to the ceramic tile back adhesive. After opening the bucket, it can be used directly after stirring evenly. Adding water will change the original formula ratio of the back adhesive, reduce its bonding strength and durability, and affect the final installation effect.
Â
In the stage of back adhesive coating and tile installation, after coating the back of the tile, it is necessary to wait until the coating becomes transparent before applying cement mortar or other bonding materials for installation. The transparent coating indicates that the back adhesive has been initially cured, and its bonding performance has been basically stable at this time. If subsequent operations are carried out before it becomes transparent, the back adhesive and the bonding material will not be tightly combined, increasing the risk of hollowing and falling off of the tiles. When pasting the tiles, it is necessary to ensure that the tiles are closely attached to the mortar. The tiles can be pressed properly to discharge the air in the bonding layer and avoid hollowing. Hollowing will not only affect the uniform stress of the tiles, but also cause the tiles to crack due to external forces in later use.
Â
Finally, the protection of finished products is essential. After the tile installation is completed, attention should be paid to the protection of the finished products to avoid damage to the installed tiles caused by subsequent construction operations. For example, during subsequent construction, avoid heavy objects hitting the tiles to prevent them from breaking; avoid sharp objects scratching the surface of the tiles to keep their appearance intact.

The above is the usage knowledge shared by Shandong ceramic tile back adhesive manufacturers. Mastering these precautions can effectively improve the quality of tile installation and extend the service life of tiles.
