There was no hollow drum when the floor tiles on the floor of my house were accepted, and there was

1. What is the reason for the hollowing of the drum?

When laying cement or adhesive is not filled well, in the floor tiles.

There are more bubbles and hollows left between the cement and the ground, and these voids are due to the thermal expansion and contraction of the air.

As a result, the air squeezing of the floor tiles in the weather changes and the hollowing of the bulge.

Partial hollowing. 2. How to deal with it?

Two situations: 1. The tiles are completely loose.

In this case, the treatment method is relatively simple, first of all, the bulging tile is carefully removed, and then the dust and impurities on the back of the tile and the base part of the ground are cleaned up, and a special tile adhesive is used.

Just paste it. Because it is a floor tile, there will be certain requirements for its compressive resistance, and the tile adhesive on the back of the tile can be evenly applied to the back of the tile when pasting, so as to avoid the hollowing of the tile as much as possible.

2. The tiles are not completely loose.

The difficulty of dealing with this problem lies in the fact that when taking out the tiles, it may cause damage to the tiles, which may involve the replacement of damaged tiles, if there is no spare tile, then it is necessary to implement with the ceramic tile seller at that time whether it can find the same color number (the same model of product, if it is not the same batch of production, its color may be different) products, and re-fill some tiles of the same color number.

There are many reasons for hollow floor tiles, such as construction errors, no gaps left in the floor tiles, poor floor quality, material problems, and low cement grades. Among them, the hollowing caused by construction errors refers to the fact that the cement of the adhesive layer is not full enough during the construction process, so that the floor tile adhesive layer and the floor tile surface are hollow, or the floor tile is not protected in time after being paved.

The materials used are unqualified, and the raw material will explode for a long time.

Usually the tile paving is completed, and so the mortar solidifies about 1 day, with a fist or a hammer or the like to knock on the surface of the tile, hear a relatively hollow sound is a hollow drum phenomenon, then deal with it in time, try to avoid strong direct sunlight within 3 days after construction, and sprinkle water on the construction of the caulking material every day within a week.

If it is found that there is a large area of hollowing, it means that the quality of the decoration is very problematic, and it can only be reworked, because after a long time, the floor tiles will crack and crack in a large area, and the sooner the rework, the better, because the decoration has a certain shelf life, and the decoration company will repave it for free.

Because the tiles are usually not checked when they are just pasted, and the hollowing drum often occurs in the process of sticking and drying, it must be checked on the second or third day after pasting.

The common way to repair the hollow drum is to shovel the sand ash, refill it with quick ash, and re-batch the putty after drying.

However, some hollow drums, due to the location and other reasons, it is difficult to chisel out, such as the hollow drum between the concrete protective layer and the base layer is more difficult, some more expensive stones, the hollow drum between the ceramic tile and the base layer, and the stone damage economic loss is greater after chiseling. This type of hollowing can be solved by the method of perfusion repair.

The AB resin grouting repair of some engineering crack treatment centers can inject high-strength adhesive into the hollow drum, and the empty position can be filled with full adhesion and compression resistance. This kind of grouting method to repair hollow drum is fast and does not damage the base layer.

Causes of formation:

When the tile is paved, the mortar is not full or the tile is not gently knocked and squeezed compact. It's a case of either cutting corners or cutting corners: to save cement mortar, or to save time.

There is another situation that mostly occurs when contracting labor and materials, that is, the quality of the tiles is too poor, and I am afraid that the tiles will be broken when tamping.

Not soaked in water or not soaked enough before paving. Tiles (especially glazed tiles) should be soaked in water for more than 2 hours before paving, so that the tiles can fully absorb water, and then take out the shade to dry or wipe the clear water. If the brick is not saturated with water, it will absorb the water in the mortar prematurely, resulting in the mortar shrinkage and hollowing, and it will also affect the strength of the paste.

Reason: If the tile is hollow, it is generally caused by improper construction, and when the tile is paved, the mortar of the cement mortar is relatively thin; Or when the floor tiles are paved, the cement slurry has dried; Or there are contaminants on the back of the floor tiles that are not cleaned, etc.

Measures: We need to ensure that the mortar of the adhesive layer is dry during construction, and it shall be scattered on the ground. When paving floor tiles, the water-cement ratio of cement slurry is 1:

2 (volume ratio between them), cement flour can not be used for direct paving. During the curing period, the board should be shelved, and it is not allowed to walk on the surface.

If there is a hollow drum now, it is best to pry open the tile of the hollow drum and re-pave it to avoid trouble in the later stage.

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.

After three years of floor tiles, it was found that the hollow drum attack was caused by what caused you hello, 1. Human reasons: the workers of the decoration company made mistakes when paving the 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 cavity is not enough, and the tile is hollow, cracked, and falling off after the tile cavity. 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:

Now there are many kinds of wall tiles in the decoration market, for the 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, "thermal expansion and cold contraction" caused by wall tiles hollow. Second, how to solve the problem of tile hollowing?

1. The corners of the tiles are hollow. You can lift the tiles a little bit by hollowing out the corners, and then pour cement mortar into the gaps again to fill the hollow drum with the Ho Ki shirt. 2. If a tile in the middle is hollow, but it does not affect the use of the overall space, it can be ignored.

3. The whole tile is hollow, it is recommended to remove it again and then pave, so that the repaired tile is more firm.

Summary. Hello, the materials are unqualified, and the raw material will explode for a long time.

Hello, the materials are unqualified, and the raw material will explode for a long time.

The Dongpeng tiles I use here, the wall, and the ground are more than 10,000 square meters, and now there is a large area of hollow.

The Dongpeng tiles I use here, the wall, and the ground are more than 10,000 square meters, and now there is a large area of hollow.

Cement and tiles are non-stick.

The cement is very strong, leaving a millimeter of seams.

What is the relationship between tiles and cement, it will be hollow.

It's been three years since I got it done.

The phenomenon of large-scale hollowing is generally caused by the noise of the cover because of the construction quality problems, so once it is found that the wall tiles have a large-area hollowing phenomenon, the construction base lead carrier should be responsible for maintenance and compensation for losses.

You're a wall brick, right?

1. The base layer is dry and the watering and wetting are not enough, so that the cement mortar loses water quickly, and the adhesion between the brick and the mortar is reduced; If the cement mortar or adhesive is paved or painted for too long, the mud will dry and will not have a bonding effect. 2. If you don't add too much mortar, the binding layer will not work. 3. The base treatment is not clean or the facing brick is not soaked in water before construction or the floating soil on the back of the brick is not removed, and the dry brick will quickly absorb the moisture in the cement mortar, resulting in the dehydration of the mortar and affecting the coagulation and hardening.

4. During construction, the mortar is not full to form a hollow drum, or the mortar is too thick, and the beating is too heavy during operation, so that the mortar sinks downward, the moisture floats, and weakens the cohesion of the mortar to return to the party. 5. After the mortar is solidified, the bricks are moved and corrected. The hollowing of the wall tiles and floor tiles means that the back of the bricks is not completely filled with cement mortar, and there is a hollow phenomenon; Or there is an empty shell phenomenon between the base layer and the mortar.

When the wooden hammer is struck to inspect, it makes a sound like a drum, and the hollow drum is one of the most common quality problems when tiling and porcelain tiles, and its main manifestations and prevention methods are as follows: (1) The hollow drum produced by the poor bond between the base layer and the dry hard mortar. produces the main hollow drum.

1. Before laying tiles, the base layer must be treated first. There should be sand, dust, etc. on the base layer without limbs. If there is, then it will have some effect on the adhesion effect later.

2. Improper coordination of newly renovated 1-year-old floor tiles hollow.

Cement mortar should be used in conjunction with water according to strict regulations. Usually, it is 1: 3, but it is also necessary to look at the specific instructions for use.

In addition, low-quality cement mortar can also affect the fit of tiles, so you must be careful when buying. It is necessary to pay attention to the use of expired cement, if the cement is expired, the adhesion effect may not be good. When you buy cement, try to choose cement for up to 3 months.

3. The newly renovated 1-year-old floor tiles are not properly placed.

When laying tiles, it is necessary to leave a certain gap to avoid expansion between the tiles after thermal expansion. In addition, a lot of people have mentioned the problem of soaking in water. In fact, most floor tiles are tiles, and the tiles themselves have a very low water absorption rate, so basically they don't need to be soaked in water; For wall tiles, many are pottery, so they usually need to be soaked in water.

Why is there no hollow drum in the tile at the time of acceptance, only after 1 year.

The main reasons for the hollowing of ceramic tiles are: when the tiles are paved, the mortar is not full or the tiles are not gently beaten and squeezed densely; The tile is not soaked in water before laying or soaked is not early enough; The plastering of the base layer of the wall is not treated as required or the garbage of the base layer is not cleaned up. 2) The tiles should be soaked in water for more than 2 hours before paving, so that the tiles can fully absorb water, and then take out the shade to dry or wipe and clear water; Check whether the plastering of the wall base meets the requirements, and the dirt and dust of the wall base must be removed; When paving, the back of the tile is covered with cement mixed mortar or 107 cement slurry and the wooden handle of a small shovel is tapped on the tile, so that the cement grout is crowded with the back of the tile, and then pressed hard to make the tile firmly combined with the wall base.

3) Special attention should be paid to the fact that when the back of the tile is full of mortar, it should be plastered into a hypotenuse on the four periphery of the tile, leaving some gaps in the middle, so that when pressing and tapping the tile, it will not cause the mortar to overflow everywhere, but also make the mortar full, and the tile and the wall are firmly combined. 4) After the mortar is solidified after the tile paving, you can use a small hammer to tap the surface of the tile to check whether the tile is hollow.

At this time, a rubber hammer should be used to knock it, so that the air under the tile can also be discharged, which can well avoid the phenomenon of hollowing. In the process of checking with a rubber hammer, it is best to knock on the four corners and the center of the tile, through which you can judge whether the tile is hollow, and you should also pay attention to your own percussion method.
