I believe that many people have such concerns when buying ceramic tiles to decorate their houses. They are worried that the quality of the ceramic tiles is not good and the ceramic tiles will fall off. I believe you will often see those exterior wall tiles falling off and causing injuries. incident, so consumers will have these concerns when buying bricks. So, let’s put aside the issue of ceramic tile quality for the time being. Then, what are the reasons for ceramic tiles to fall off? Let’s take a look together!
When this happens, many people will say that either the button adhesive of the food group is of poor quality, the tiles are not good, or the decorator’s paving skills are not good, so which one is it? , come and take a look with Mr. Zhongtao.
1. Improper selection of tile adhesive. For vitrified tiles or stones with low water absorption, high-performance adhesives should be used;
2. The rigidity of the base surface cannot meet the installation requirements of ceramic tiles and stone, and there is deformation. This problem is prone to occur if the lightweight partition wall is deformed.
3. The back of the tile or stone has not been cleaned, and there is dust or release agent that affects the bonding strength.
4. The amount of adhesive is not enough to form a full paste.
5. After the tiles or stones are laid, the surface material is not pressed into the adhesive, so no effective bond is formed
6. The base surface is not well leveled, the thickness of the adhesive layer is uneven, and the shrinkage unevenness caused during the drying process of the adhesive is large, resulting in local hollowing.
7. If the thickness of the adhesive is too large, it will shrink greatly during the drying process and easily cause hollowing. The most appropriate thickness is 6 to 8 mm.
8. After combing the stripes with the adhesive, the tiles were not laid in place in time. The opening time of the adhesive has expired, which can easily cause hollowing and falling off.
9. Uneven mixing of the binder or failure to stir according to regulations, such as adding sand and cement at will, will cause unstable performance of the binder, easily lead to weak bonding force, and eventually cause hollowing and falling off.
10. 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 construction is performed reluctantly.
11. Ceramic tiles and adhesives will undergo thermal expansion and contraction when the temperature changes. If the gaps between the tiles are not enough, stress may occur between adjacent tiles and they may squeeze together, resulting in various warping corners and hollows. , it will fall off in severe cases. Therefore, seams must be left when laying ceramic tiles.
12. The finished surface is not effectively protected during the curing period. When the ceramic tiles are subjected to pressure, impact and external vibration during the curing period, they may easily cause hollowing or falling off in the later period.
After reading the above content, you may have a detailed understanding of the problem of tiles falling off, so have you mistakenly blamed the tiles and the decorator? In such a situation, the decorator will inevitably be shot while lying down! A normal person would think this way. If I don’t blame you, who should I blame? Cover your face, O(∩_∩)O haha~ slip, slip, slip!
