There are many reasons why tiles fall off, not necessarily all of them are waterproof s fault, do yo

1. The putty layer on the wall is not cleaned 2 The ratio of cement and sand is incorrect 3 The wall tiles are not soaked before laying 4 The water absorption rate of the tiles is not up to standard 5 The plastering of the base layer is not done well 6 The wall foundation is not watered 7 The tiles are not enough to leave the joints 8 The cement label is not selected properly 9 The second knock 10 The cement mortar is unevenly paved.

The base layer is not firm, and the sand is falling, which has nothing to do with moisture. Solution: First of all, the loose base layer should be removed, then the smoke and dust should be removed, the waterproof putty should be brushed, and the dry and irritated should be scraped with Yigao polymer repair mortar, so that the next waterproof project can be carried out inside.

It may be that the adhesion is not strong enough, or the surface of the base layer is not smooth, unclean, cracked, sandy, etc.

After the waterproofing construction of the bathroom, the tiles fall and annoyance. It is really not cost-effective to ask workers to work again and bother, and to spend money and effort. So why did the bathroom fall? Don't worry, let me explain it to you in full detail.

After the waterproofing of the bathroom, the façade becomes smooth and does not absorb water. When pasting tiles, it is both slow and patient, and the tiler master will fall off if he does not paste well. There is a solution to this, just buy cement mortar to pull the hair on the wall, and you're good to go.

If you can't buy it, you can simply dispose of it yourself. It is to mix some 107 glue and other rubber powder in the water, and then add some appropriate amount of cement to the prepared barrel, and finally stir it evenly with an electric drill, and you can use a broom to pull the wall hair. After the waterproof construction of the bathroom, there is no brushed wall, and it is very easy to drop bricks.

Tiles are further divided into two types, half tiles and full tiles. Semi-ceramic tile has strong permeability to water, and the water absorption rate is more than 0.5%; The water absorption rate of the whole tile is less than 0.5%. It is recommended that the bathroom is half tiled.

Another point is that if you buy half a tile, you must first wet it and then paste the tile; And after buying all tiles, I am afraid of soaking in water. Therefore, which kind of tile to use and whether it is soaked in water is also one of the reasons for the tile to fall off.

When the bricking master is tiling, the proportion of sand mortar must be moderate. Then the bricks are coated with brick mortar before they can be pasted on the façade, and they should not be rushed. There is a good saying, fast workers are not good to live, slow workers produce skilled craftsmen, isn't it?

Therefore, the conscientious technique of the tiler master also determines whether the tile falls off.

The design requirements of tiles are tightened in order not to leave gaps; In addition, for the sake of aesthetics, the existing tile gaps of the tiles have been treated with beautiful seams. These two design requirements will cause the mortar in the tile to be unable to drain out, and become a hard ash block or loose slag with no cohesion. Because the inside is made of a waterproof layer, it cannot seep inward; The outside was closed and discharged.

Therefore, the moisture that cannot be discharged from the tile is also the culprit that causes the tile to fall off!

All in all, after the waterproofing construction of the bathroom, the tiles will fall; It is nothing more than the waterproof layer is not brushed, the tile selection is not right, the construction plan is not suitable, the tiling master is in a hurry, the tile design requirements are not standardized, etc., these reasons are caused!

It may be that the tiles are not very firm when they are pasted, resulting in the tiles falling when they encounter water when using the bathroom in the later stage.

Because the tile is not firmly pasted, the tile is hollow, and then by the action of gravity, the tile will fall.

It may be that your waterproofing measures are not in place, or it may be that the quality of your tiles is too poor.

The main reasons for the hollowing off of tiles:

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.

The two aspects that you have little to do with are mainly the problems in the construction process of wall tiles, including interface agents, back coating glue, etc.

The main reason is that the tile is not permeable, and then the waterproof layer is to do a good job of hanging grout treatment in advance, and two steps are indispensable.

Home decoration with a variety of materials, including ceramic tiles, some owners of the wall decoration, the choice of ceramic tiles instead of the traditional Nippon paint wall, although the tile paste fashion atmosphere on the grade, but there are also a variety of quality problems. The brick itself, before the tiles, a lot of dust has to be removed from the tiles. Nowadays, many exterior wall tiles are porcelain, and the water absorption is not strong, but there is a lot of dust on the surface of the tiles, which should be cleaned up.

The surface flatness error of the base layer is larger, far more than the general plastering requirements of the specification, and even reaches more than 1, and the masonry paving tile feels uneven and taps, which may lead to uneven mortar and form a hollow drum. Because as the water absorption rate of ceramic tiles decreases, we all know that the difficulty of pasting is getting higher and higher. Therefore, the appearance of low-absorbent tiles is a fundamental reason for the tiles to fall off and show themselves.

Knock a few times on the wall, or scratch a few times on the wall with a key, according to the test evaluation, you will know the bonding strength of the cement mortar and the wall, and the test is not hollow, and the tile can be pasted.

When these materials appear sandy, hollow, cracking, and damp on the surface, the surface materials of the wall will not be able to stick to the wall, so that the wall tiles will fall off, which is also one of the reasons why the wall tiles fall off. The ** of tile cement is higher than cement, and some people mix tile adhesive in cement slurry in order to save money, which actually changes the ratio of tile cement and becomes the uncertainty of pasting.

If the water absorption rate is low, it means that the product has high strength, is not easy to expand, and has high internal stability, while the water absorption rate is too high, which is easy to cause the expansion and cracking of the green body, which will lead to the wall tiles falling off or the floor tiles hollowing. There are many reasons why the tiles fall off, the glue powder is less, and the bonding strength is not enough, one is that most of the ceramic tiles have low water absorption, and a considerable number of people like large bricks on the wall, and the other is that the corresponding tile adhesive is not selected according to the size of the ceramic tile water absorption, especially the large bricks need to be backed with tile adhesive and tile adhesive to be used together.

Tile falling off may be because of the quality of the tile, or because the cement of the tile is not sticky enough, more is a long time of wind and sun, so the tile falls off, there is also a possibility that the wall is more wet, so the tile falls off, there is also the wall and ground base treatment is not clean or the watering is not moist enough, the water absorption rate of the tile is low, and the tile will fall off.

It may be that the floor is not cleaned before the tiles are laid, or the ground is not watered enough and not too wet, or the mud is too thick, which will cause the tiles to fall off.

There are many reasons for falling off, for example, because the glue is not firm when it is glued, it may also be because the quality of the glue is not very good, which is often touched in ordinary life, resulting in them not being firm, or it may be because the quality of the choice is not very good, which will also cause them to fall off.

It is very likely that the tile does not fit with the glue. There is also some lime on the tiles that has not been cleaned up. The tiles were not flattened.

When constructing, I don't apply some adhesive strips indiscriminately. The amount is too small when it is fixed with glue. There is a lot of dust on the back of the tile that is not cleaned, which will cause the tile to fall off.

In most cases, it is caused by the poor quality of the tile, or the poor water absorption of the tile, so it is also prone to this problem. The proportion of cement is not carried out according to the standard, and it is also prone to tile detachment.

The treatment is not clean or the wetness is not enough, or it may be that there is too much mud when laying, or the soaking time is not long, and the stains are not cleaned. Or the tile has a very low water absorption. It could also be a problem with the geology, or it could be a lack of intensity.

Or natural causes. Improper construction.

What to do after the bathroom is waterproofed to ensure that the tiles do not come apart? Pay attention to the following details when the bricklayer is constructing, you can ensure the service life of the tile.

Before we do the bricklayer construction after the waterproofing, we must carry out brushing treatment on the wall, otherwise the tile and the wall are not firmly bonded, and it is easy to break away from the hollow drum and other phenomena, there are many people who say that when pasting wall tiles, you can choose to use tile paste instead of cement mortar, which is what we call the thin paste method, and the wall can not be brushed, which is not correct.

Regardless of whether we are carrying out the construction of bathroom wall tiles, whether we choose the thin paste process or the traditional process, the wall should be brushed first.

After we live in a new home for a period of time, the bathroom wall tiles will be hollow, falling off and other phenomena, which are generally related to the quality of construction, but more or not to the original wall to block the brushing base treatment, so when we choose workers, we should also pay special attention to the craftsmanship level of the bricklayer master, do not leave regrets for the decoration of your home because of greed for cheapness.

Strictly control the ratio of sand and cement, and mix sand cement according to the proportion, which can give full play to the role of cement, so as not to affect the adhesion of wall tiles because the dosage is too large or too insufficient, and eventually lead to hollowing, detachment and other phenomena.

You can also choose to use 108 construction adhesive, and when we paste the wall tiles, the glue is evenly painted on the wall to increase the adhesion between the cement mortar and the original wall.

Don't rush to check whether the wall has quality problems after pasting Jian Li Lu's good wall tiles, it is best to wait for the wall to dry before knocking, otherwise it is easy to cause the adhesion between the cement mortar and the original wall and wall tiles, and eventually lead to hollowing and other phenomena.

As we all know, ceramic tiles are still relatively common in our lives, many people will choose ceramic tiles when decorating, but if you don't pay attention, the tiles will fall off, which is for a certain reason, and then I will introduce it to you.

First of all, we need to know the reason for the tile falling off, a total of three kinds, the first is because of the problem of the tile itself, you must know that there are many types of tiles on the market, and at the same time, it is not the same, if you buy some inferior tiles, then it will naturally fall off after a long time of use, so in order to prevent the occurrence of this phenomenon, in the decoration of the family, try to buy some better ceramic tiles, so that not only can be used for a long time, but also can prevent the tile from falling off. The second kind of tile falling off is related to the operation of the worker has a certain relationship, if the worker in the process of sticking the tile is not firmly or more sloppy, then it will lead to the phenomenon that the tile is not firm, so in the process of use will also fall off, which has a relatively large impact on us, and even hurts our body.

In addition, it also has a certain relationship with the wall in their own family, if the bearing capacity of the wall is relatively poor, or the wall appears to be damp for a long time, in a humid environment, the tiles will also fall off, so in life when we are pasting tiles, we must explain the wall of the room and the master of the tiles clearly, otherwise the tiles will fall off, which is likely to cause the falling tiles to hit our head or body. Thus causing us a certain amount of harm.

Finally, it is necessary to regularly let workers come to overhaul, overhaul can not only prevent the occurrence of tile falling off, but also maintain the service life of our tiles, so we must choose some better ceramic tiles when pasting tiles, so as to reduce the phenomenon of tiles falling off and even cracking.

It may be caused by the wrong way of installing the tiles, it may be that the tiles are cracked, or it may be caused by the poor quality of the bricks, or it may be caused by the instability of the wall, or it may be caused by the tilting of the wall.

It may be because of the purchase of refining tiles, improper operation by workers, the service life of the tiles is up, the water absorption rate of the tiles becomes low, and the tiles are not cleaned before they are pasted.

It is most likely because it was not glued tightly when it was pasted, or because there was a lot of moisture in it, or it could be caused by a collision.

The reason for the hollowing, the reason for the choice of cement, the reason for the choice of tile adhesive, the reason for the weight of the tile, the reason why the tile is not soaked in water.

Reasons why tiles fall off include:

1. The putty layer of the wall has not been cleaned.

There is a layer of putty on the wall of the rough house, which needs to be cleaned when laying tiles, and the hairs are chiseled with steel wire. If it is not cleaned up, the cement mortar and the wall are not firmly bonded, there will be hollowing, even if the tile and the cement mortar are well bonded, it will fall off.

2. The wall tiles are not soaked before paving.

Many wall tiles are tiles, and the water absorption rate of porcelain tiles is greater than 10%, if they are not soaked before paving, the water in the mud will be absorbed, resulting in hollowing and cracking, and even falling off.

3. The water absorption rate of ceramic tiles fails.

The water absorption rate is too high, the density of the tile blank is loose, easy to absorb water, and the tile will cause the surface to crack after thermal expansion and contraction, and even the overall tile peeling off. If the water absorption rate is too low, the adhesion between the tile and the cement will not be formed, and the chance of falling off will be greatly increased.

4. The grassroots plastering is not done.

If the base plastering is not cleaned, the moisture of the cement mortar will be absorbed by the dust and other deposits of the base layer during paving, and the bond quality will be affected, which will eventually lead to hollowing or falling off.
