What should I do if the tiles are hollow and fall off? Is there a remedy?

In the case of tile hollowing and falling off, we can apply 107 glue mixed with cement and other materials on it until the mortar inside is completely hardened, if it is a large area falling off, there is no remedy, it must be re-laid。If the tiles are laid at the wrong time, it will not only lead to a longer setting time, but also tend to cause the tiles to hollow and fall off during use, which is very troublesome to remedy, and we need to decide how to deal with them according to the situation of falling off.

If the number of tiles that fall off is not too much, and the mortar inside is not loose, we only need to scrape the mortar around the back of the peeling tile first, mix 107 glue into the cement paste, and evenly apply it on the back of the tile, press the painted tile, and wait for the complete introduction. If the cement under the tile will loosen with the wall, it will be relatively troublesome to deal with, because it is necessary to find some small pits on the original foundation to facilitate subsequent bonding.

The same is to scrape all the sand corners on the back of the tile, mix 107 glue into the mortar, and re-paste the falling tile. We can also use cement, acetone and other materials to mix together in proportion, first use a brush to gently brush a layer on it, paste the peeling tiles on it and wait for a while, until the paste material inside is all hardened. We need to pay attention to not to hit the mortar too hard during the operation, which will cause the tiles that were originally firmly pasted to be shaken loose.

If the tiles at home are hollow and falling off very seriously, we must remove all the tiles that have problems, remove the original cement slurry layer, and reapply the cement, which is equivalent to reworking from beginning to end, which greatly increases the amount of labor. And when cleaning, you should also pay attention not to break like tiles, so as not to be able to use it twice. In order to prevent similar things from happening, we must buy more tiles at one time when decorating, and we should also paint waterproof materials and do closed water experiments during the laying process.

1. If the mortar is not loosened, only the tile falls off, and the tile is not damaged, clean the back of the tile and all around, mix a little cement into the 107 glue into a paste, evenly coat a thin layer on the back of the tile, and then press the tile to stick firmly. In addition, you can go to the supermarket to buy a special tile adhesive and paste directly, if it is a non-humid place, you can also use silicone.

2. If the mortar falls together with the tiles, first gently chisel some pits with a chisel on the original foundation surface, and then re-inlay them with mortar mixed with 107 glue. If the tiles are only partially detached, do not hit the mortar on the foundation surface to prevent the original solid tiles from being loosened.

In this case, you need to re-pave it, so as to avoid the problem from appearing again, and it is best to find a professional master to operate.

In such a situation, you should first clean up these hollow or falling tiles, and then paste them with some more suitable tiles.

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.

1. Choose a tile with a deep texture on the back.

Ceramic tiles will be designed on the back of the design into a grain shape, this is to make the tile and the wall can be better close contact, easy will not fall off, it is worth noting that the deeper texture can ensure that the tile and the cement mortar layer are partially detached but will not fall off, so you should pay attention to it when purchasing, try not to choose the back of the tile with too shallow texture.

2. Choose tiles with low water absorption.

If you want to avoid the hollowing of the tile, a good way is to avoid the purchase of tiles with too high water absorption, when the tile is purchased to understand its water absorption, the main detection method is to drop water on the back of the tile, to see the speed of infiltration after the water is dispersed to judge, the slower the water absorption, the greater the density of the tile, on the contrary, it means that the density of the tile is relatively sparse, the water absorption rate is relatively high, so the tile should try not to choose, because the water absorption rate is too high, it will be easy for the tile to absorb water and expand and the hollow drum falls off.

3. The effect of choosing Zhongsha is good.

Another way to avoid tile hollowing is to choose good sand, generally sand can be divided into extra-fine sand, fine sand, medium sand and coarse sand according to the thickness of the four kinds, the coarser the sand out of the cement mortar strength will be higher, but you know, not the higher the strength of the representative of the better, too fine sand is not a good choice, because the adsorption capacity is relatively poor and difficult to paste the tile, so it is recommended to choose the sand in the home decoration, because its particle thickness is more moderate and suitable for use in the cement mortar as an auxiliary material for pasting tiles.

4. The ratio of cement and sand should be moderate.

In home decoration, the general floor tiles are dry paved, and the cement and sand are mixed with a small amount of water in a ratio of 1:3. The general wall tiles are wet paving, and the ratio of cement and sand is according to 1:

The ratio of 2 is more suitable after mixing with water. Too high a cement mortar ratio will lead to excessive water loss after drying, which will lead to the hollowing of tiles.

At present, the more common cement on the market is divided into 225 and 525 four types, different types of cement will adapt to different concrete needs, in the home decoration generally use 325 cement will be better, because in the home decoration cement does not need much bearing capacity, so do not have to choose high-grade cement, and in addition, in the purchase of cement to pay special attention to its quality, to avoid the selection of inferior products as much as possible.

Carefully knock off the tiles that are going to fall, and then clean up and re-paste a piece of it, in order to have a better effect, it must be the same type of tile Oh thank you!

Due to the reason of thermal expansion and contraction, the tile will be hollow, it is recommended to knock off and repaste a piece.

If it is a floor tile, you can clear the brick joints, use a vaccine syringe to inject some cement slurry into it, and wait for it to dry completely. The wall tiles can be cleared out of the brick joints, with a glue gun to fill the brick joints with glass glue, and the glue can be dried, if it has fallen off, clear out the fragments of the mortar, hit the back of the brick with curtain wall black glue, directly paste it as it is, press flat, and the glue will be OK!

Use tile adhesive, no bricks, no hollowing. Now home decoration tiles are generally used. You can buy it online, and it's not high. I've bought the Nedford brand before, and it's still very useful.

The hollowing of tiles at home is mostly caused by the uneven application of mortar during construction and the insufficient adhesion of cement and river sand. As for how to deal with it, this depends on the number and severity of the hollow drums. If the area of the hollow drum is relatively small, then it is recommended to knock off the two tiles, and then use the same color tile to repair it, but if the area of the hollow drum is relatively large, it may be recommended to re-paste all of them.

There are two commonly used methods for attaching tiles:

1.One is to use traditional cement river sand to paste, the advantage is that it is relatively cheap, but there are many disadvantages, such as the construction steps are more complex, easy to hollow, fall off, etc., so now it is gradually replaced.

2.The other is to use special ceramic tile bonding materials, such as porcelain stickers to paste tiles, which not only the construction steps are relatively simple, but also save a lot of manpower and material resources; Moreover, the adhesion is strong, not hollow, not falling off, and not slipping; Water-resistant, moisture-proof and environmentally friendly and non-toxic, it is a very suitable tile bonding material.

In fact, everyone knows that floor tiles are hollow and falling off in interior decoration are common phenomena. Why are there so many hollow floor tiles today?

The reverse side is not clean, and there is a layer of dirt and ash. Tap water soaking is insufficient. The quality of cement mortar is unqualified. Unreasonable preparation, unreal engineering construction bonding and other factors caused by hollowing and falling off.

Different types of hollow drums have different correct ways to deal with them.

Treatment: grouting to fill the void.

If the hollow drum is generated on the edges of the four corners of the floor tiles, the method of filling cement slurry can be used. The floor tile joints at the hollow drum at the edge of the slurry are scraped. Concrete is synthesized into a very thin and thin cement slurry.

While hitting the hollow drum with a metal hammer (causing it to vibrate), pour cement slurry into the gap (so that the cement slurry slowly spreads over the hollow drum).

Advantages:

This type of solution saves costs and does not easily lead to damage to the floor tiles.

Treatment: pry brick repaving.

If the floor tile is partially hollow, the hollow drum part is generated in the middle of the floor tile, and the floor tile must be removed how to carry out the paving. After the edge hollow drum passes the grouting, there is still a hollow drum and must also be resurfaced.

It is not easy to cause harm to the surrounding floor tiles.

Defects

Because the floor tiles have been damaged, there must be a reserve floor tile of the same model.

Treatment: revise the bottom layer, pave the floor tiles again, the total area of the hollow drum "1 3 The total area of the floor tiles, all the bricks must be removed, and the bottom layer will be dug up again and then paved with floor tiles. Generally speaking, large-scale hollowing is caused by unreasonable installation.

Treatment: Cement slurry again.

If the hollowing degree is more serious, the floor tiles have been completely loosened, indicating that the cement mortar layer under the floor tiles and the bottom layer of the pavement have also been loosened, and the cement mortar layer can be removed with special tools such as ash knives, and the cement mortar is wiped again and the floor tiles are paved. If the floor tiles are only partially loose, do not hit the cement mortar on the basic surface vigorously to prevent the solid floor tiles from being loosened.

Solution: Able to no longer be resolved.

If there is a slight hollowing of the floor tiles on the wall pavement, such as the baseboard on the fabric sofa, the unloaded floor tiles in the corner of the room, and the bed underneath, it can be considered that there is no need to repair it. Or whether it is harmful to the installation of kitchen cabinets, basin cabinets, shower heads and electric water heaters, or whether the parts are in the kitchen cabinets and hanging cabinets and other furniture, the hollow floor tiles have cabinet boards against the porcelain will not fall, and you can also choose to avoid the solution.
