What causes the bathroom tiles to fall off together with the surface of the mortar?

Improper construction is completely the problem of the construction party!

There was a situation in a relative's house, the house that had just been renovated, and within a few months, the tiles of the bathroom fell off along with the bottom mortar, which was harmfulRelatives can only temporarily glue them together in whole with scotch tape to prevent them from falling and injuring people

Later, because it was impossible to contact the workers who applied the tiles at that time, there was no way to call another group of workers to repair the fallen tiles. ResultsThis group of workers directly pointed out the reason why the tiles detached along with the surface of the mortar

Bathroom tiles are falling.

1. If the tile is soaked in water, the mortar on the back will be very firm, which is why it falls together with the tile. And this just shows thatAt that time, the construction party of the tiles did not water the wall (wall base watering), that is, the mortar on the tiles did not stick to the wall

Clean the wall foundation before tiling.

2. There is also thatBathroom walls have not been cleaned or shaved。For example, if the wall is too smooth or has a lot of dust, in fact, it is not conducive to the tile sticking to the wall, resulting in the mortar falling together with the mortar later.

Wall tile joints are treated.

3. Then there is the lack of tile jointsIt leads to thermal expansion and cold contraction in the later stage, squeezing each other and falling off。In addition, there are:The wall foundation is uneven, the mortar is unevenly applied and the mortar ratio is unqualifiedAnd so on.

The mortar is applied unevenly.

To sum up, it can be seen that if the bathroom tiles fall off together with the surface of the mortar, it can basically be identified as a problem of the construction party. Due to their improper construction at the time, it caused the problem of tiles falling off later. If, of courseThe wall is not suitable for a certain tile or must be treated before it can be attachedThen the construction party should have explained it at that timeBut if they don't say anything and deliver it like this, then it must be their responsibility!

In the case that the cement mortar of the tile meets the requirements, the problem occurs, there are two main reasons: one is that the cement mortar on the back of the tile is unevenly applied to form a hollow drum, the second is that the cement mortar plastering wall is too dry, when the cement mortar is pasted with the tile, the dry wall base is not sprinkled with water, which causes the wall to absorb the water in the cement mortar too quickly, thereby shortening the normal solidification cycle of the cement mortar, resulting in the reduction of the bonding effect. Among them, the first situation is often a local hollow drum falling off, and the second is easy to cause a large area of tiles to fall off.

Of course, it was caused by too much moisture.

You used a flexible waterproof material to make the wall waterproof, which caused the subsequent tiles to stick to it.

The waterproof material needs two indicators to achieve the bathroom wall, one is active adhesion, and the other is passive adhesion. Active adhesion means that the waterproof material needs to stick to the wall, which requires the wall to be rough and the waterproof material can be brushed; Passive adhesion means that after the waterproofing is done, the subsequent decoration, such as the tile can be glued with tile glue.

Your problem is that the passive adhesion of the waterproofing material is not good. Generally speaking, passive adhesion is related to the following factors, one is the flexibility of the material, the more flexible the material, the worse the passive adhesion, and vice versa; Second, it is related to the water absorption, the smaller the water absorption, the passive adhesion is out of tolerance, and the stronger it is; Third, it is related to the construction time. The longer the construction time, the worse the passive adhesion, and vice versa; Fourth, it is related to the flatness of the wall, the smoother the passive adhesion, the worse, and vice versa; Fifth, the higher the polymer content of the material, the worse the passive adhesion, and vice versa.

The waterproofing of the bathroom falls off with the tiles, because it is not occupied when doing waterproofing, so he will fall off with the tiles after sticking the tiles, and when the waterproofing must be done again, the wall must be done, not so that it is glossy, it must be pockmarked surface, so that the waterproof can be occupied.

Hello! It is mainly caused by factors such as the wrong method or the unclean wall.

Tiling should be done like this:

1.When using adhesive paving, the base wall should be flat, vertical, and square at the corner of the sun and yin. 2.Dust and debris should not be mixed into the binder.

3.Stir according to the requirements of binder use and water addition, stand still for about 10 minutes, and then stir again before use, and use up the mixed binder within 2 hours.

4.After the wall tiles are paved, if you need to adjust the gap and flatness, you can adjust it within 20 minutes of putting the wall on the wall.

5.The adhesive in the gap should be cleaned in time.

6.Seamless bricks and antique bricks and other ceramic tiles should be left according to the product description and requirements.

7.The yang angle should be spliced with 45° edging, and the edging should be straight without explosion.

The bathroom waterproofing falls off with the tiles, which can be understood as a quality problem. For example, the cement at the bottom is empty if it is not plastered, and this situation will occur after a long time of dampness.

There is no interface treatment during the waterproofing treatment, and the waterproof material and wall are not grasped.

The main reason is that the wall has been aged and weathered, probably because the cement strength of the wall is not enough, and the original water-cement ratio does not match, resulting in sanding after the cement solidifies.

To answer your bathroom waterproofing and tiles falling off together, what's going on?I thought that the bathroom was too damp, so the tiles would definitely fall off, so if it was dirty, the tiles would fall off, so the tiles often touched the water, so the tiles would fall off over the years.

That means that the temporary rotation is strong, not fixed, or your cement number is not too big, the tile is not grasped, so this still needs to be reworked, the next time to do waterproofing, or personally recommend to find a professional some engineers.

What is the problem with the bathroom waterproofing falling off with the tiles?This shows that one is that at that time, waterproof, the quality of the tiles is not in place, and then the quality of the material is not good, and the time has been for a long time, it may be that it has fallen off naturally.

If this happens, it means that the glue on the wall of your room is not properly painted. Or the strength of the brush is not enough, so his tile is really not firm and falls off. If you want to do it again, you must do a good job of the bottom layer of the wall.

This is the waterproofing of your bathroom, and the tiles are not well done, and the sticky ones are not firm and firm at that time, so this kind of thing will happen.

This is the waterproof quality is too inferior, and I really help you look forward to adoption.

What is the reason why the bathroom wall tiles fall off with cement: The reasons why the bathroom wall tiles fall off with cement are as follows: 1

The cement mortar mix ratio is unreasonable 2When pasting, it was not full of ash, and it was not full of 3The wall was not cleaned before pasting, and there may be unclean factors such as oil stains4

The tile paste was not moistened with water before, causing the tile to absorb the moisture in the imitation mortar, which affected the strength of the mortar. If you want to re-paste, first remove the falling off and hollow tiles, clean up the wall, if necessary, you can use a chisel to chisel hair, control the cement mortar mix ratio, and tell the worker to say that the base is full of ash and do not empty the drum, and the tile is soaked in water before pasting. Zhifiber.

Not long after the bathroom decoration, the wall tiles began to fall off, many people do not know what the reason is, and they are also very distressed, which affects the activities of washing and showering, which is very unsatisfactory and has certain potential safety hazards. So why do bathroom tiles and wall tiles fall off and what are the reasons? There are mainly four reasons: the water absorption rate of ceramic tiles is not up to standard, the base treatment is not good, the temperature of tiles is too low, and the construction technology is not standardized.

Generally speaking, the water absorption rate of bathroom tiles and wall tiles is less than 18%, but in fact, there are many tiles in the market that do not meet this standard, some have reached 20%, or even 25%, which shows that the tiles are very easy to expand after absorbing water.

There is a bonding process for laying bathroom tiles and wall tiles, and if the wall base is not cleaned, it will not achieve a good bonding effect. When the wall base is too smooth and the tile base is too dry, the backwater of the base layer will be accelerated, resulting in no resistance between the two and cannot be tightly combined. If the wall surface is uneven or has a vertical deviation, the ash is too thick and easy to produce mortar sink, and the adhesion is poor.

The plastering of the base layer is too thin, and it will not be strong.

When carrying out the construction of bathroom tile wall tiles, it is best not to choose in winter. Because the temperature is low, it will affect the condensation quality of the building materials, and the low mortar will freeze. However, when the weather is warm, the slow cracking and collapse will slowly thaw, and a large area of tiles will fall off.

If the decoration happens to meet the winter, these building materials must be soaked in water, and the water saturation will avoid falling off caused by low adhesion.

When paving bathroom tiles and wall tiles, it is necessary to stir the mortar, if the mixing is uneven, the strength and waterproofness will be greatly reduced, which will affect the bonding with the base layer. If the operation and strength are not standard enough, the position of some face bricks will deviate, and then when correcting, it is necessary to continue to knead and press, so that the ring bonding layer will be broken.

When we paste tiles on the wall, the first thing we need to make sure is that the bottom layer of the wall is in compliance with the tile pasting regulations. If the bottom layer of the wall does not meet the regulations, most of them will fall down in the middle and later stages, so before pasting tiles, the first thing to check is the actual arrogance of the wall. When the tiles caused by the wall fall, the back of the general tile contains a lot of wall cement mortar, which is very easy to distinguish.

The wall causes the tiles to fall, and the actual reasons are as follows.

The compressive strength of the wall does not meet the requirements of tile pasting. Because most of people's walls are walls with cement mortar plastering layer, this kind of wall has a certain porosity, so it is to meet the requirements of pasting tiles. However, cement mortar may not have enough compressive strength due to a variety of reasons.

For example, one of the most common conditions is that there is sand falling off the wall. In this case, the tiles that you have pasted will immediately fall off the wall and bring cement mortar. This is the compressive strength of the bottom layer can not reach the pasting of tiles.

The wall is hollow. The hollow drum of the wall is the separation of the plastering layer of the wall and the middle of the wall. Since the plastering is all achieved on the bottom layer of the wall.

For example, plastering concrete walls, or plastering walls. Plastering is used to level the walls and then to apply tiles. However, if there is a wall hollowing between the plastering layer and the wall, then after everyone pastes the tiles, because of the external force added by the bricks, the plastering layer will fall off from the wall immediately.

At this time, you will notice that the concrete wall or wall inside is immediately exposed, so this is also very easy to distinguish.

The first step is to solve the problem that the compressive strength of the plastering mortar on the wall is not enough or that the wall is hollow. Remove all the plasters that have any problems and clean them, and pour the walls with dampness to meet the plastering standards. Hanging label plastering.

In this kind of area, I propose that everyone immediately hang the steel mesh, use the fixed nails of the special steel mesh to fix with the wall, stick to the wall, and carry out plastering in the future. After the plastering has achieved compressive strength, everyone comes to paste the tiles again. Then you can fix the tiles in those places again.

Tile detachment may be due to the unclean treatment of the wall base or due to the quality of the tile. We apply tile adhesive to the tiles.

Because the inside of the bathroom is too damp, the durability of the tiles is not so strong, and the solution is to re-apply the tiles.

In terms of tile quality: the water absorption rate of ceramic tiles is too low, resulting in weak viscosity with cement, causing falling off, and insufficient water soaking before the tile is on the wall, resulting in weak viscosity with cement and falling off. Find a good craftsman to take a look at it, repair it, and if it is large, you will have to start all over again.

If the wall mortar is not loose, only the ceramic is falling off, then the residual mortar on the back of the tile must be cleaned first, and then the tile is glued with a new mortar. If the wall mortar is also loose, water it with water before repairing, cut the mortar into raw embryos, and after the wall is completely dry, paste the tiles with ceramic glue. If only the tiles have fallen and the cement remains on the walls and floors without releasing them, the solution is to scrape off the remaining mortar on the back and sides of the tiles, then apply an even layer of mortar on the back of the tiles and press it back into place.

If the mortar that falls off the bathroom tiles is not loose, only the tiles have fallen, then you can scrape all the mortar on the bricks, and then add an appropriate amount of cement to 107 glue and stir it into a slurry. Then apply a thin layer on the back of the tile. We often find this happening.

The tiles on the bathroom wall began to fall off. When most people find out about this situation, they will be overwhelmed and very painful, if the tile falls due to the collision of a hard object, before repairing, water the wall first, fill the mortar behind the tile, and then slowly clean the cement with a tool until you see a blank wall. Finally, when the walls are completely dry, the tiles are glued with ceramic glue and glass glue is used, which is the silicone we commonly use in our decoration. It's easy to do it yourself with a glue gun.

Drill some coarse wells first, and then re-mount them with mortar with 107 glue. Press the tiles firmly against the wall. After some time, when the mortar is basically hardened, remove the hand.

It is stipulated that the water absorption rate of ceramic tiles shall not exceed 18%, but the water absorption rate of many tiles has reached 20%, and the maximum value exceeds 25%. When the tile absorbs water, the brick expands. If the weather is cold again, there will be peeling, cracking, and even bursting and falling.

Buy tiles that don't absorb water so that there won't be too much moisture in the bathroom, because if it rains, there won't be water droplets in the tiles. Buy tiles with non-slip materials on the surface, and now there are many types of non-slip tiles, among which my personal better is glazed tiles, because of its good anti-slip properties, and it is also quite affordable.
