What is the culprit that causes the tile hollow to fall off?

Due to the change of seasons, the ambient temperature drops sharply, and if the paved wall tiles are not completely dried in the cement slurry, the water in the mortar will be completely dripped. When the temperature rises again, due to thermal expansion and cold contraction, there will be a void between the wall tiles and the base layer, and finally the phenomenon of hollowing will appear.

The main culprit of the hollow tiles is that the tiles were not carefully attached to the decoration at that time, resulting in a gap between the wall and the tiles, resulting in the hollowing of the tiles.

There are many reasons for the hollowing of ceramic tiles: uneven walls, improper proportion of auxiliary materials, insufficient reserved gaps, insufficient water soaking of porcelain tiles, limited bricklayer technology, etc. Most of the tile hollowing off is caused by the lack of clean treatment of the bottom layer.

The phenomenon of hollowing and falling off of ceramic tiles is more common in life, mainly due to the effect of thermal expansion and contraction, followed by long-term damp and dark environment, and if there is a vacancy and air inside before decoration, the tiles will also fall off in the later stage.

Although there are many phenomena of tile falling off in life, there are people who can control such a phenomenon, and once they fall off, it will cause safety accidents, so we must find a way to prevent the situation in advance.

1. Thermal expansion and cold contraction lead to shedding.

Thermal expansion and contraction is actually a kind of object that expands when it is heated, and then contracts when it encounters colder, which is due to the fact that the motion of particles in the object will change with temperature, and when the temperature rises, the vibration amplitude of the particles increases, causing the object to expand, resulting in corresponding consequences. The tile here is an object, once the surrounding ambient temperature is relatively high, then the inside will expand, once the expansion of the tile will fall off. <>

Second, moisture leads to shedding.

Of course, if it is a family tile or an outdoor tile, often in a rainy day or a damp and dark environment, then the tile will be due to the change of the internal structure, coupled with the effect caused by the rain, it will make the tile fall off, of course, this phenomenon is rarely in a relatively stable situation, unless it has reached a certain number of years will fall, so the reason for this happens, most of it may be because there are no good materials used in the decoration, many workers may be cutting corners, Therefore, it is easy to cause the tiles to fall off in a humid environment. <>

3. There is a vacancy in the interior before the renovation and it may fall off.

There is also a situation because the bottom of the original tile will be put a layer of cement for solidification during the decoration, but because the tile is not fully covered when the cement is placed, it leads to a part of the exposed air or there is a vacancy, once there is such a phenomenon, there will be a natural fall off when it is heated or extreme weather, and the probability of this phenomenon will be very large, so before the decoration, especially the installation of tiles, the host must conduct a detailed field visit and full supervision. <>

Fourth, the solution.

1.If it is an indoor environment, the installation of tiles requires a field visit before installing the tiles, and the foreign objects around the tiles must be discharged in advance, and the tiles must be installed close to the wall without leaving gaps.

2.Remember to keep the tiles dry when using them, so as not to make the surrounding tiles damp, so that the tiles can be kept longer and used longer.

Tile falling off is not formed for a while, many times because of the influence of the environment for many years and the influence of the weather, so no matter what the situation, we must prevent the phenomenon of falling off in advance.

This is because of the reason for thermal expansion and contraction, and the way of pasting is related, the mason master is not good, this situation will also occur, under normal circumstances, as long as it does not exceed the proportion, there is no need to solve, if it is more serious, it needs to be re-paved.

Mainly because the cement quality is not good, it is not compacted when pasting tiles, and the time of soaking in water is relatively short, which will lead to the hollowing of the tiles falling off. At this time, you should find a master to remix the cement and then re-pave.

First, the influence of the grassroots. 1. If the base layer (that is, the floor tiles or the wall tiled with tiles) are not cleaned, it may cause a hollow drum between the dusty tile bases. 2. The watering of the base layer is different before paving, and the dry place will be quickly absorbed with water, which will affect the adhesion force.

3. Because the surface deviation of the base layer is too large, the plastering time is too thick or the plastering time of each layer is too tight, which will cause the imbalance of the dry shrinkage ratio, which will affect the quality of the tiles. Second, the reason for the material. 1. The tiles that need to be soaked are not soaked or the soaking time is not up to the requirements, so that the mortar is dehydrated too quickly in the early stage, which affects the adhesive force, or the sliding self-fall caused by the paste is not dried after the tile is soaked in water.

2. The mortar mix ratio is not standard, the mortar is uneven, the sand content in the mortar is too large or the sand is too fine, and the same construction surface uses different mix ratio mortar, etc., which are the reasons for the hollowing or falling off of the tile. 3. The human factor. 1. The thickness of the adhesive mortar is not applied when the tile is paved.

First, or the coating is not full, the force is uneven when pasting the tile, and the tile is finely adjusted after the mortar collects water, which may cause the tile to be hollow or fall off. 2. There are no seams left in the tile pasting or the hook joints are not tight after the seams are left, there is no watering and maintenance if it needs to be watered and maintained, and the porcelain width is delayed and the bricks are paved before the time is reached. Well, that's all there is to say, of course, the reasons for the hollowing of the tiles are not all these, as well as climate, temperature, etc., even if it is the tile that begins to look very tight, but after several frosts and snow freezes will also make it hollow or fall down, which is also the reason why the outer layer of high-rise buildings is not tiled.

The contact between the tile and the wall and the floor is insufficient, resulting in the loss of support, and the bearing leads to problems such as falling off, arching, inability to drill, cracking, etc. Most of the hollow drums appear in the four corners of the tiles, one or more of them, here is a detection method, five-point percussion detection method: use a metal rod to hit the four corners and the center of the tile, and judge whether the tile is a hollow drum by the sound of percussion.

If the percussion sound is more muffled, the paving is more solid. On the contrary, the sound of "dong dong dong" is clear, indicating that the walls and floor tiles are not well paved, and there are hollow drums. The hollow drum rate is also the standard, the hollow drum rate of the floor tiles should be controlled within 3%, and the main channel can not be hollowed; The empty bucket of wall tiles needs to be controlled within 5%, that is, the empty bucket area of the tiles cannot exceed 5% of the tile area.

After the home is renovated, if the tiles on the wall are hollow and fall off, it is estimated that everyone will be very depressed at this time. Then I will think, how can we ensure that the wall tiles we paste do not appear hollowing and falling off? Let's go to the point where we need to know a little bit about this.

The most fundamental reason for the natural fall off of ceramic tiles is that the bonding is not good, there are many types of tiles, such as porcelain tiles, vitrified tiles, glazed tiles, etc., although they are all ceramic tiles, but the construction method is slightly different. This mainly depends on the craftsmanship of the bricklayer, bonding is the main reason, and other reasons also have a certain influence.

Decoration is a very hard thing, from the material into the decoration workers to start the decoration, running back and forth every day, the material, the construction progress, the master's craftsmanship are all in mind, I am afraid that it is not easy to decorate once, there are such and such problems. Finally, the decoration was completed, and it didn't take long for the tiles to fall off, and think about how bad it should be. When paving tiles, no bottom sealing treatment is carried out, or inferior stone bottom sealants are used, resulting in too fast evaporation of water at the bottom after paving, and a gap is formed between the adhesive and the stone, resulting in hollowing of tiles and other bulging phenomena.

Generally speaking, the natural falling off of tiles is the bathroom, kitchen, balcony, and other spaces with relatively harsh environments, and the wall is hollow, and falling off is a thorny problem. There are two phenomena of tile peeling, one is that the tile itself and the adhesive layer fall off, in this case, the back of the tile is clean, without cement mortar or tile mortise. If you use a full tile, it is easier to fall off if you don't use the back glue, and the whole tile does not absorb water.

This situation generally has the following several reasons, the first is that the brick master is not serious about the mortar is not filled, this is generally a local hollow, the problem is not big, the second reason is that the wall is too dirty and the powder layer is not clean, the mortar is dry and the wall does not have a good bonding effect, the probability of falling off should be noted.

This is because the tile is not soaked in water, or it may be because of the choice of tile adhesive problems, be sure to choose the right tile, you need to pay attention to the choice of tile adhesive.

In the process of tiling, if you do not choose the right tile adhesive or there is a problem with the cement ratio used, it is likely that the hollow drum will fall off. Extra care should be taken during construction.

The main causes of tile hollowing include:

1. Human reasons: the workers of the decoration company are caused by mistakes when laying wall tiles; For example, before paving the tiles, the leveling of the wall base is not in place, and the uneven wall contact with the tiles will cause hollowing. In addition, the surface of the base layer is not clean or the base layer is relatively loose, which will also affect the viscosity of the tile, resulting in the hollowing of the tile and falling off.

The tile adhesive is scraped unevenly, the tile and the wall can not be fully contacted, the flatness of the tile is not enough after pasting, and the tile is hollow, cracked, and falling off in the back. When mixing cement mortar, try to use the machine to stir, and wait until the active ingredients in the tile adhesive are completely integrated before paving the tiles.

2. Ceramic tile product quality problems: there are many types of wall tiles in the decoration market, for owners who do not know much about the decoration industry, it may be a difficult thing to choose cost-effective wall tiles, and poor quality wall tiles often lead to the phenomenon of hollowing.

3. Climatic conditions: wall tiles will be affected by external climatic conditions, and "thermal expansion and cold contraction" will cause wall tiles to be hollow.

One reason is that the base layer is hollow and seepage, which affects the pasting effect of tiles. The second is that the brick is not soaked in water during tile construction, or the quality of the pasting material is not good, and the bonding material is not full. The third is that the protection of the finished product is not in place, and the cement slurry is loosened before the final solidification.

The cement mortar did not hit the whole tile, the other is that the wall is too dry, the water of the tile is quickly absorbed as soon as the cement mortar is pasted, and there is another is that the tile is not soaked in good water, some are soaked for too long and some are not soaked enough, in short, there are many reasons, you need to actually check and judge.

There are two reasons why the tile hollow drum falls off, the first is that the brick is not paved well, the cement slurry is not all combined with the tile and the ground, and the second aspect is the quality of the tile itself, the tile is warped, so it causes the hollow.

Before the tiles are paved, they need to be soaked in water. Poor treatment of the base layer: the base surface needs to be cleaned first, otherwise it will affect its bonding effect.

Improper construction technology: tile falling off is also caused by improper construction, not according to the correct paving method to construction.

A large area of hollow drumming falls off, that is, the bathroom kitchen Where the wall tiles are pasted, it is generally a waterproof material problem The wall tiles are hollow and fall off The reasons are: 1. The wet expansion rate of ceramic tiles is too large; Solution: Before the product is palletized and packed into boxes, the drying time of the wax must be taken into account to avoid wax sticking to the bottom of the brick; 2. The cement is unqualified; Workaround:

purchase of qualified cement; 3. The ratio of cement mortar does not meet the requirements;

The main reason for the hollowing of the tile is that the cement is not in place, and the cement is not ground in the middle of the rock, or there are empty passages everywhere, so it is said that the tiles fall off.

Hello, most of the reasons for the hollowing of ceramic tiles are caused by the lack of craftsmanship of workers, the lack of decoration materials, and the lack of waterproof layers.

The main reason is that the technique of the plastering master is not up to par, and it may be that the material is not good.

1.Soak in water problems.

The tiles have been soaked in water for too short a time, or they have not been soaked at all. At this time, sticking the brick to the wall will cause the tile to absorb the moisture in the cement mortar, causing the mortar to be too dry and the adhesion to be reduced.

On the contrary, if the water is soaked for too long, the tile will not absorb the moisture in the cement mortar at all, nor will it - the cement must rely on the tile to absorb water and penetrate into the surface of the tile at the same time to achieve the purpose of full bonding.

2.Smoothing issues.

The cement mortar should be smoothed evenly, and if there is no cement, it will be hollow; If there is less cement, it will not be able to do even the most basic bonding, which will naturally lead to falling off.
