Ask how to prevent tiles from falling by sticking tiles.

Brick falling from the wall comes from using pure cement slurry when sticking tiles, and tiles are not stuck according to the instructions. When pure cement slurry expands, its strength is high, which is easy to cause the tiles to squeeze each other and explode and crack, while the tensile force during contraction will make the cement slurry gradually separate from the tiles, resulting in hollowing or even brick falling. Just like blowing a balloon, the balloon has a telescopic limit, and if it continues to blow beyond the limit, it will explode; When deflated, the balloon will constantly deviate from its original position as it contracts. Now all kinds of polished tiles, floor tiles and big stones are common on the wall. The combination of these bricks and cement is weak and the gravity is strong. If the construction is improper, bricks will fall off more easily. Some suggestions on preventing brick falling 1. Please ask the master to use the tiles according to the instructions. Ceramic tile packaging of regular manufacturers is generally equipped with detailed instructions for use, with clear guidance and suggestions on the use environment, operating specifications and matters needing attention. For example, in the aspects of cement mortar ratio, soaking, paving and seam leaving, if the whole construction process is operated according to the requirements of the product manual, there will generally be no problem. Pay special attention to the prohibition of pure cement slurry when paving tiles, and leave gaps. Pure cement paste has obvious thermal expansion and cold contraction reaction. If there is no gap or the gap is too small, the tension and pulling force of the cement slurry will make the tiles squeeze each other and crack or even fall off. Fine sand is mixed into cement slurry, and the ratio is generally cement: sand = 1:2. Soak the tiles before construction, leave gaps during construction, and construct according to the requirements of tile description. Note: Some motherboards add glue to increase adhesion. Glue is a kind of irritating chemical substance, which is harmful to human body. Use with caution! 2, before the wall tile waterproof. The location of the wall brick is generally the bathroom and kitchen, with long-term water accumulation and heavy moisture. It is suggested that waterproof and moistureproof measures should be taken before laying bricks, and at the same time, wall structure changes and tile discoloration caused by water vapor leakage should be avoided. However, due to the waterproof function of the waterproof layer itself, the construction specifications should be strictly followed when laying tiles on the waterproof layer. The wall is waterproof, and it is recommended to use general waterproof slurry for painting. General products have strong adhesion, which is convenient for subsequent tiling. Moreover, it is forbidden to paste tiles with pure cement slurry after waterproofing. When pasting, it must be constructed according to the requirements of tile use, leaving gaps. 3. It is recommended to use mortar glue or tile glue. Tile glue is an improved special cement mortar. By adding additives, the cohesive force of cement mortar can be greatly improved, thus affecting the thermal expansion and cold contraction coefficient of cement mortar. As long as the gaps are reserved according to the requirements of ceramic tiles and the construction is standardized, cracking, hollowing and brick dropping can be effectively prevented, and the thin-layer construction method can also greatly improve the construction efficiency. Mortar glue is the latest patented product developed by Leibangshi Company, which is concentrated by various additives. Mortar glue is mixed with water, cement and sand in proportion, which can play a role similar to tile glue, reduce transportation trouble, and is convenient to construct, economical and practical. 4. Special materials should be handled with care. Occasionally, some marble slabs or large stones will be used in home decoration.
