Why do wall tiles crack?

Answer: There are many reasons for the cracking of wall tiles: on the one hand, the water absorption rate of wall tiles is large, especially the humid environment of the bathroom, the green body absorbs the moisture in the air and expands, and the glaze layer does not expand to produce stress, and it will crack when it exceeds the bearing capacity of the glaze.

Another aspect is due to the improper selection of adhesives for construction, if the ratio of cement, sand and water is not appropriate, the stress caused by the volume change of the curing process will exceed the bearing capacity of the glazed brick and crack.

There are many reasons for this. For example, wall tiles that have not yet dried properly, problems with the level of bricklayers, changes in the earth's crust, and wall subsidence. It is mainly caused by uneven thermal expansion and cold contraction Well, if it is an exterior wall brick, it is mainly caused by uneven thermal expansion and cold contraction because the foundation is not well laid, and the load-bearing structure:

The quality of cement is not up to par, and the steel bar cuts corners, resulting in cracks caused by the weight of the wall, and the thermal expansion and cold contraction material is added less when paving.

First, the water absorption rate of wall tiles is large, especially in the humid environment of the bathroom, the green body adsorbs moisture in the air and expands, and the glaze layer does not expand to produce stress, and it will crack when it exceeds the bearing capacity of the glaze; On the other hand, due to the improper selection of adhesives for construction, if the ratio of cement, sand and water is not appropriate, the stress caused by the change in volume during the curing process will crack when it exceeds the bearing capacity of the glazed brick. Bohua tiles. Satisfied.

There are several reasons for tile cracking, the first is that the wall cracks causing the tile to follow the cracking, and the second is the cracking of the tile itself.

The first type generally needs to be treated on the original wall to solve, and the cause of wall cracking is complex, and even involves structural problems. Take it seriously.

The second reason is actually more human. All the tiles sold on the market can be said to be qualified products, but why do they cause cracking? The main reason is that the construction workers are not familiar with the properties of the tile itself, and blindly follow the unified method of construction.

All-porcelain bricks, terracotta bricks, gypsum additive tiles, etc., have different requirements for the construction process. The most important thing is that the water absorption rate of tiles is different during the construction process. For example:

Clay and tiles containing gypsum have a large water absorption, and if they are not soaked for a long time during construction, they will cause hollowing and cracking.

Many people find that the problem of cracking occurs when the new house is just renovated, which not only affects the aesthetics, but also makes people very depressed. What causes cracking of wall tiles? And what should be done?

1. What is the cause of cracking of wall tiles?

1. First of all, it may be because the quality of the selected wall tiles is too qualified, and the quality will also affect the hardness in the later stage, including its bearing capacity.

2. It is also possible that the tiles are not soaked in water during construction, and generally speaking, when the tiles are dissipated, the tiles need to have a certain water absorption. If there is no soaking water, the cement will lose a lot of water in the later stage, which will cause cracking and falling off.

3. Another point is that the choice of cement mortar is not up to standard, the strength is not enough, it will lead to the wall tiles are prone to crack the situation, some people choose the tile adhesive, but this adhesive is unqualified, it will also lead to the effect of pasting.

4. The last reason is that it is not paved according to certain specifications, such as the need to leave a certain gap between the tile and the tile, otherwise it will be easy to expand in the later stage of thermal expansion and contraction, which will lead to cracking of the tile, and even the phenomenon of hollowing and falling off in the later stage.

Second, how to remedy tile cracking.

1. There is a repair pen or repair agent on the market that specializes in repairing tile cracks, but it can only be used for small cracks on ceramic tiles, including scratches. First of all, we need to clean the surface of the tile, apply it directly with a repair pen or squeeze the patching agent into the gaps.

2. If the cracking phenomenon is more serious, more than one or two, it is necessary to eradicate the strong ones, choose qualified tiles of qualified quality, and at the same time choose qualified adhesives and lay them in accordance with certain specifications. Soak the front pants in water during the sleepy period, then apply the tile adhesive to the back of the tile and gently tap it on the wall with a rubber mace. There is a certain distance between each tile, so it is not easy to crack in the later stage.

I conclude: you must pay attention to the quality of the products in the early stage, and at the same time, you also need to ask professional masters to help you paste the wall tiles, so as to ensure that there will be no cracking problems in the later stage.

In the construction of houses, ceramic tiles are very important materials, especially in the cooking area and the bathroom, these two special spaces, ceramic tiles are indispensable materials, but many people find that ceramic tiles in the use of Zhaoye for a period of time regret the appearance of cracks, seriously affecting the overall aesthetics, so what is the reason for the cracks in the wall tiles? Let's take a look at it below, I believe it will bring you different insights. What are the reasons for the cracks in the wall tiles: 1. There is no gap left when tiling or the reserved gap is too small; 2. The tile is not fully soaked in water before construction, and the water in the mortar will be absorbed after construction; 3. The wall tiles are cracked due to improper operation during cutting; 4. The composition of the mortar is improper; 5. The treatment of the grassroots is not standardized.

What are the precautions for the construction of wall tiles?

First, before the construction of the leveling, must clean up the base, such as the wall of lime plaster, wallpaper, etc., these need to be cleaned, otherwise the cement mortar and the base can not stick, in addition, if there are cracks in the wall, it needs to be treated and then tiled to prevent more serious cracking and falling off in the future, these are the preparations that need to be done before paving. Second, the laying order has to pay attention to many people in the tile paving, random construction, in fact, the construction of ceramic tiles is in a certain order, for the sake of beauty, should be the bottom of the bricks should be left for the last paving, and so on the wall tiles are paved, and then paved floor tiles, in addition to the paving of wall tiles, do not stick to the top at one time, otherwise it is easy to cause collapse. Third, the wall tiles should be fully soaked I believe that everyone knows that the wall tiles have a good moisture content, so before construction, they must be fully soaked, at least 20 minutes before use, otherwise it will greatly affect the adhesion of the paving, and the water absorption rate of each brand of products is different.

Summary: What are the reasons for the cracks in wall tiles and what are the precautions for the construction of wall tiles, I hope to provide you with some help. If you want to know more about decoration, you can pay attention to the relevant information of Qeeka Home.
