There are many broken wall tiles in the bathroom in less than a year, what is the reason?

1. The base treatment of the wall and ground is not clean, or the watering is not moist enough;

2. The cushion cement mortar is too thick or adds more water;

3. The floating dust on the back of the tile is not removed or infiltrated with water is not enough, and the stain on the back of the tile is not cleaned up when paving, and there are too many water traces, resulting in unsolid bonding;

4. The water absorption rate of the national standard for porcelain bricks is E 0 5, and the national standard for ceramic bricks is 10, so the adhesive force is far weaker than that of ceramic bricks, the shrinkage and expansion rate of porcelain bricks is about 4 10 6, and the shrinkage rate of concrete is more than twice that of porcelain bricks.

5. The water absorption rate of porcelain bricks is low, such as when it is not completely pasted with cement, it is subjected to large impact force (such as heavy object impact, trampling, etc.), which causes the separation of two different objects of brick and cement, and the hollowing of the bottom of the brick;

6. Due to the inconsistent density of the mortar, the mortar will settle after the completion of the initial setting period, resulting in hollowing and loosening;

7. The cement does not meet the requirements, etc.;

8. Different from the thermal expansion coefficient of cement, there is a temperature difference stress after the paving of large-size tiles, and the seasonal temperature difference oscillation will cause the bonding strength to decrease;

9. The back pattern of the product itself is unreasonable or there is a lot of brick base powder attached to it, and no corresponding measures are taken in the construction.

10. Between the tiles, especially the large-scale bricks, the joints are too small, and the thermal expansion and cold contraction of the tiles squeeze each other to cause warping and cracking.

It is possible that there is lime in the construction material, which is easy to expand when exposed to water.

Construction problems or material problems may also be caused by vibrations.

There are many broken wall tiles in the bathroom in less than a year, what is the reason?

Hello dear, glad to answer for you. There are many broken wall tiles in the bathroom in less than a year, what is the reason? There are two reasons for the cracks on the wall tiles in the bathroom mold for a year, the first is that there is a possibility that the foundation sinking of the slag condition affects the cracks on the wall, and the tiles are cracked, and the second reason is that the cement mortar of the tiles is too thick, and the cement density caused by the cave shed is too high, and the tiles will crack due to the influence of cold expansion and heat contraction, and there may be bricks.

Cracked bathroom wall tiles are a very common problem, especially after months or years after the renovation of a new home, many people will encounter this problem. Cracked tiles not only affect the aesthetics of the bathroom, but also may cause problems such as water seepage and leakage, which brings certain safety hazards to the house. So, what should be done after the bathroom wall tiles are cracked?

First, understand the causes of tile cracking.

There are many reasons for tile cracking, but most of the time it is caused by external causes such as temperature changes, foundation settlement, leakage from water pipes, etc. In addition, poor brick quality can also lead to tile cracking.

Second, the method of dealing with tile cracking.

1.Replace the tiles.

If the cracked tile is not very serious, but only some subtle cracks have appeared, you can consider replacing it. This prevents the crack from propagating and affecting the overall aesthetics. Pay attention to the color of the new tile to be the same or similar to the original to maintain the overall coordination.

2.Re-fix the tiles.

If the cracked tile is more severe, but has not fallen or fallen off, consider refixing the tile. The specific method is to knock off the tile with a hammer, then apply a special tile glue on the back of the tile, and then re-paste it.

This effectively strengthens the tile and prevents it from cracking further.

3.Reinforcement of the back of the tile.

If you find that multiple tiles are cracked, or the quality of the back of the tile is not up to par, you can consider reinforcing the back of the tile. The specific method is to first break the cracked tiles, then apply special reinforcement materials to the wall, and then paste the new tiles on the first preparation.

This effectively increases the stability of the tile and prevents it from cracking again.

4.Redecorate the bathroom.

If there are a lot of cracked tiles and there are serious cracks in the walls, you can consider redecorating the bathroom. This can not only deal with the problem of tile cracking, but also optimize the overall bathroom decoration effect. Of course, the cost of redecoration is relatively high, and you need to consider your own economic strength.

3. Methods to prevent tile cracking.

1.Choose *** tiles.

When buying ceramic tiles, it is necessary to choose products with the highest quality and consistent specifications. If there is a problem with the quality of the tile, it is prone to cracking.

2.Pay attention to the quality of construction.

The construction quality of bathroom wall tiles also has a certain impact on tile cracking. If the construction is not standardized, the tiles are not firmly pasted, and it is easy to crack. Therefore, when decorating the bathroom, we must choose a regular construction team to ensure the quality of construction.

3.Pay attention to temperature changes.

The bathroom is a damp place, and the water temperature fluctuates greatly, which can easily cause tile cracking. Therefore, when using the bathroom, it is necessary to pay attention to timely ventilation, maintain air circulation, and reduce the humidity in the bathroom. Also, do not set the water temperature too high when bathing, so as not to expose the tiles to excessive thermal expansion, which may lead to cracking.

Kai Qin Qin. To sum up, cracking of bathroom wall tiles is a very common problem, but it is not impossible to solve. When dealing with tile cracking, it is necessary to choose different methods according to the specific situation, and pay attention to the methods to prevent cracking to maintain the aesthetics and safety of the bathroom.

1. Wall deformation: The cracking of tiles caused by wall deformation will present regular cracks in the horizontal, vertical or oblique directions.

2. Unqualified paste: Unqualified paste will also lead to problems such as hollowing and falling off after tile paving. Conventional tiles are usually laid with cement mortar as an adhesive, and cement and mortar are usually in accordance with 1:

1 ratio to the ratio, if the ratio is uneven, the cement mortar can not achieve the required bonding effect; In addition, the high soil content of the sand and the use of inferior or expired cement will lead to problems such as poor pasting and hollowing and falling off of tiles.

3. The tile is not soaked in water: if the tile with a certain water absorption rate is not soaked in water before paving, after paving, in the process of condensation and strength rise of cement mortar, the tile will absorb its moisture, resulting in cement water loss and no adhesion, reduced strength, and reduced adhesion of brick to cement or cement to the original wall, resulting in hollowing and falling off.

4. There is no gap between the tiles: if there is no appropriate gap reserved during paving, it will also lead to the tiles being squeezed and cracked, hollowed out or falling off.

Precautions for wall tile paving 1, wall tile paving order.

Generally, when the master paves the tiles, he will first pave the wall tiles, and then pave the floor tiles. This is also convenient for the paving of floor tiles, the wall tiles should be cleaned up before paving, and the wall tiles are generally paved from the beginning of the sunny corner or the door and window side from top to bottom, from left to right.

2. Soak the wall tiles in water.

We all know that there are many tiny voids inside the tile, which makes the tile have a certain water absorption. Therefore, it is recommended to soak the wall tiles in water before paving, otherwise the tiles after paving will absorb the moisture in the cement sand, resulting in a gap between the tiles and the cement. Phenomena such as falling off and hollowing are formed.

In particular, the wall tiles in the kitchen are mostly made of ceramic tiles, which will quickly fall off if they are not soaked in water. When the tile is soaked, the water must not pass the tile, the time can not be less than 30 minutes, so that the tile will not bubble in the water and then take it out and dry.

3. The wall tiles are positioned and arranged with bricks.

Before pasting the wall tiles, it is also necessary to pay off and arrange the bricks, so that the tiles are more neat after paving. It is generally recommended that the non-whole bricks should be arranged in the corners, and it is best not to have two rows of non-whole bricks on a wall, and it should be noted that the width of the non-whole bricks should not be less than one-third of the whole bricks. Otherwise, it will affect the aesthetics of the overall wall.

4. The width of the gap between the wall tiles is uniform.

Before pasting wall tiles, it is necessary to determine the horizontal and vertical aspects, the joints should be straight, and the width of the gaps should be uniform. In case of pipelines, switches and other protrusions, it must be cut with whole bricks, and must not be pieced together with non-whole bricks. Do not pave the wall tiles to the top at one time to avoid falling and injuring people due to unstable paving.

5. Pre-paving of wall tiles.

The wall tiles also need to be pre-paved before paving, so that you can check the effect of paving in advance, and you can adjust if you are not satisfied with the travel file. If there is no pre-paving, if you pave it directly, it will not only be troublesome and laborious to knock it down if you are not satisfied with it later, but also increase the waste of funds.

6. After the wall tiles are paved.

After the paved wall is dry, you can detect and check the hollowing of the tile and the phenomenon of color difference, if the hollowing rate exceeds 5%, it is regarded as unqualified and needs to be re-paved.

Summary. Improper immersion of wall tiles.

It may be that the surface brick is not well soaked in water, and the surface brick is too dry, resulting in too fast water backflow of the adhesive mortar, which affects the firm bond between the adhesive layer and the surface brick. Or because the face brick fails to dry after being immersed in water, or even leaves floating water on the surface of the face brick, when the face brick is combined with the adhesive layer, an excess water film sliding layer is formed between the bottom surface of the wall tile and the adhesive layer, which affects the bonding effect of the adhesive layer and the surface brick.

2. The grassroots is not handled well.

The surface of the base layer is too smooth, and if the base layer is too dry before pasting the wall tiles, it will cause the base to return water quickly, and it is difficult to close the bond between the bonding layer and the base layer due to the lack of friction resistance and bonding moisture. In addition, due to the uneven surface of the external insulation wall, or the vertical deviation of the wall, the local plastering and plastering on the surface of the base layer are too thick, resulting in the mortar falling due to the adhesion of the adhesive mortar, which will affect the combination of the surface brick and the base layer. The base plastering is too thin, not easy to bond and compact, and will also cause the surface layer to fall off, affecting the combination with the base layer.

What is the reason for the wall tiles in the bathroom to burst out?

Improper water immersion of wall tiles may be poor water immersion of face bricks, and the water return of the adhesive mortar caused by excessive dryness of the face bricks is too fast, which affects the firm bond between the adhesive layer and the face bricks. Or because the face brick fails to dry after being soaked in water, or even leaves floating water on the surface of the face brick, when the face brick is combined with the adhesive layer, an excess water film sliding layer is formed between the bottom surface of the wall tile and the adhesive layer, which affects the bonding effect of the adhesive layer and the surface brick and disturbs the results. 2. If the base layer is not well handled, the surface of the base layer is too smooth, and the base layer is too dry before pasting the wall tiles, which will cause the base to return water quickly, and it is difficult to close the bond layer and the base layer due to the lack of friction resistance and bonding water.

In addition, due to the uneven surface of the external insulation wall, or the vertical deviation of the wall, the local plastering and plastering on the surface of the base layer are too thick, resulting in the mortar falling due to the adhesion of the adhesive mortar, which will affect the combination of the surface brick and the base layer. The base plastering is too thin, not easy to bond and compact, and will also cause the surface layer to fall off, affecting the combination with the base layer.

3. If the temperature is too low when tiling, the coagulation effect of cement and other materials will be affected, and the tiles will fall off. Construction should be avoided as much as possible in winter, because the temperature is low in winter, the mortar is frozen, and after thawing in the spring of the next year, the brick is heavy, and it is easy to fall off the command. For example, in the winter construction of Qiaojiguo, the floor tiles and tiles should be soaked in water before paving, and the water must be saturated.

4. The quality of the bonding mortar is not good due to the improper construction process, the mixing ratio of the mortar is not accurate during construction, the mixing is uneven, the strength is not enough, the workability is poor, and the water leakage is poor, and the balance stool will affect the bonding strength of the wall tiles and the base layer.

If it helps you, please give it a thumbs up.

Thank you.

I believe that many of us are no strangers to bathroom tile cracking, and I also found that bathroom tile seems to be more prone to cracking than tiles in other places, but how much do we know about the reason? In addition, how can we prevent the bathroom tiles from cracking?

1. Cracks caused by the impact of man-made hard objects.

This kind of crack is generally caused by the owner's own improper operation in the process of use, because the tile material is fragile, it is easy to cause permanent crushing or cracks, which cannot be recovered. At the same time, such damage is not within the scope of the three guarantees, and the owner is generally solely responsible for maintenance and compensation.

2.Cracks caused by wall deformation will appear in transverse, longitudinal or oblique regular cracks.

There are many reasons for the deformation of the wall: the change of temperature, or the damage of thunderstorms, or the wrong design of the wall structure, or the subsidence of the foundation of the house, etc., are easy to cause the cracking of the tiles attached to the wall. This type of cracking is more complicated.

It is recommended to find the cause of the cracking of the wall, and after the crack is stabilized, fill the joint with cement mortar and resin mortar to protect the cracked part of the tile.

3. The quality of the tile itself.

Generally, the probability of cracks in cheap bricks is greater, because the soil used in the firing of the tile body is too secondary, and the water absorption rate is high, especially when it rains before winter, if the tile absorbs water, it will crack. This problem does not occur with all-porcelain bricks. Here's a solemn reminder:

The purchase of toilet tiles should still choose trustworthy brand products, and do not cause irreparable losses because of greed for cheapness.

4. The tile adhesive is unqualified.

Unqualified adhesive will also lead to problems such as hollowing and falling off after tile paving. Traditional paving tiles usually use cement mortar as a paste, cement and mortar are usually proportioned according to the ratio of 1:1, if the ratio is uneven, cement mortar can not achieve the required bonding effect; In addition, the high soil content of the sand and the use of inferior or expired cement will lead to problems such as poor pasting and hollowing and falling off of tiles.
