What is the situation of tile hollowing? What are the effects of tile hollowing

There are many reasons for the hollowing of tiles, generally including the following aspects:

1. Caused by construction technology.

Wet-laid tiles are prone to hollowing. When wet paving, due to the high moisture in the cement mortar, in the natural drying process, the moisture penetrates into the base layer, and large and small cavities are formed after drying, and the floor tiles can not be fully bonded with the base layer, and there will be hollowing.

2. Construction technical problems.

Tile laying is the most common construction method in decoration construction, and the requirements for workers' skills are very high. Unskilled workers will also form hollow drums due to improper operation and other human reasons during the construction process. It is mainly manifested in the following aspects:

1) The grassroots is not clean. The base layer has not been thoroughly cleaned, and there are floating soil or sand particles left on it, and the cement mortar is actually stuck with the floating soil and sand particles after being paved, and it is not integrated with the base layer, and it is easy to appear drum phenomenon over time.

2) The watering of the base layer is not moist enough. Water is indispensable in the solidification process of cement, so if the base layer is not wet, it is difficult to solidify firmly with the cement mortar.

3) The cushion mortar is laid too thick or added too much water, or it is not fully compacted.

4) The floating ash on the back of the tile is not brushed, or it is not moistened enough with water, which affects the bonding.

5) After paving, the tile and the base layer are not completely dry (generally it takes 1 2 days) to receive external force, such as walking on it, knocking, etc., so that the tile loosens and falls off.

3. Cut corners.

In order to save time and materials, the general decoration team often only plasters sand plaster on the four corners of the tiles, and then paves the tiles. Just laid, because the four corners are fixed, so the tile looks very firm, but there is no sand and dust in the middle under the tile, and it will cause bulging due to the different expansion coefficients over time.

4. Environmental and seasonal reasons.

Due to the change of seasons, if the temperature drops suddenly, the moisture in the mortar cannot be completely dried when the cement mortar is not completely dry. When the temperature rises, due to thermal expansion and contraction, there will be a void between the tile and the base layer, and then loosen and fall off, forming a hollow drum.

When the material is unqualified or the construction is improper, there will be hollowing between the tile and the structural layer due to the pasting and combination of the unstable combination. Tile hollowing is also divided into local hollowing, corner hollowing, hollowing between the cement layer and the wall, and hollowing the wall itself.

As a novice decorator, it is not very clear what the impact of tile hollowing will be. But don't worry, I'll give you a brief introduction to the question of what will be the impact of tile hollowing.

1. Because the tile at the hollow drum is not forced, it is easy to crack when it is subjected to external force in the future.

2. The hollow drum may also cause the tile to gradually expand the scope of the hollow drum in the future use process, and finally cause the tile to warp or fall off.

3. In addition, hollowing will also lead to difficulty in drilling holes in the wall in the future, and it is easy to break tiles (such as: installing water heaters, mirrors, pendants, cabinets and bathroom cabinets, etc.).

4. The hollow drum will also cause water accumulation in the bathroom floor, and it will rot and stink (the reason why the bathroom in many people's homes smells is this).

5. The hollow drum reflects not only the appearance, but also reflects that there may be serious problems in the construction process (for example: there is no hair before laying bricks).

What to do if the tiles are hollow.

1.Shouhu first used the hollow drum hammer pants pin to knock on the wall, so as to further confirm the scope of the hollow drum. If the sound of percussion is dull, it means that the paving is firmer. On the contrary, if there is a crisp sound of "dong dong", it means that the tile has a hollow phenomenon.

2.Divide and mix the two components of tile hollow drum repair glue AB, and stir well, and then use a clean syringe to inhale.

3.Above the wall in the hollow area, open the ceiling close to the wall.

4.Inject tile hollow drum repair glue into the ceiling, and inject it into the gap between the tile and the wall, so that it can naturally flow into the hollow position.

5.Of course, you can also open holes in the tile caulking above the scope of the wall hollow, which can be hit at the "ten" or "one" to avoid damaging the tiles.

6.Then inject tile hollowing repair glue into the opening. If there is any spilled glue, try to wipe it off with a damp cloth before drying. If there is glue oozing out of the caulk, it is because the original caulk is not dense enough, and a layer of dense caulk can be reapplied.

7.If there is external expansion and loosening of wall tiles, it is recommended to use external force to push back the wall tiles, such as wooden sticks.

8.Finally, the hole is filled with caulk. And wipe off the excess caulk, and then check the wall after drying, you will find that the wall is not hollow.

Summary: After reading the above introduction, I believe you have a further understanding of the impact of tile hollowing. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.

Tile hollowing will affect the service life and aesthetics of the tile. Hollow tiles are prone to cracks and damage, and will also affect the qualitative and load-bearing capacity of the tiles. In addition, hollow tiles are prone to accumulate dust and dirt, which is difficult to clean and affects aesthetics.

If left untreated, hollow tiles can also lead to water leakage and dampness on the walls, affecting the indoor environment and health. Therefore, Ming Du found that the tile stool hollow drum should be repaired or replaced in time.

Hollowing is an occasional phenomenon in tile paving. There are ways to avoid it.

1) The backfill in the center of the atrial is strictly layered and evenly firm.

2) The base concrete should be vibrated compacted and leveled, and the uneven places should be leveled with sand and mud, and the height difference should be controlled within 10mm.

3) Sweep the base layer and water it one day in advance.

4) The water-cement ratio of the cement slurry of the binding layer is controlled at about 0 4, and it is evenly swept with pouring, so that there is no water accumulation, slurry accumulation and no dry spots.

5) Winter maintenance to avoid local temperature too low.

The repair method for the hollow drum that has appeared: for the corner of the room or the hollow drum (no crack) with an area of no more than 0 2 square meters, it is generally not repaired. For the hollow drum of frequent personnel activities, the hollow drum part is chiseled off first, cleaned up, watered and moistened one day in advance, and the cement slurry mixed with 107 glue is brushed on the bottom surface and around the repair first, and then repaired with the same cement mortar as the original ground according to the construction points.

If there is a large area of hollowing, the entire surface layer should be chiseled off and re-paved. Lesman tiles have a high degree of flatness, which effectively prevents hollowing.

1.Construction Issues:

During the construction process, the cement oil of the adhesive layer is not full, resulting in a void between the adhesive layer and the tile surface. After the tile paving is completed, the finished product is not protected in time. The construction site is chaotic, and the construction personnel carry out construction or trampling when the tile adhesive layer is not hardened, which loosens the adhesive layer and the base layer and produces hollow drums.

When paving, not enough shrinkage expansion joints are reserved, because there are not enough expansion joints, under the action of thermal shock expansion or wet expansion, stress squeezing and warping occurs between adjacent ceramic tiles, resulting in the phenomenon of hollowing and falling off.

2.Grassroots issues:

Before sticking to the wall and floor tiles, the dust and garbage on the surface of the base layer are not cleaned or there are many loose sand particles on the surface of the base layer, forming an isolation layer between the base layer and the adhesive layer. The base layer is too dry, and it is not watered and moistened before construction, which causes the base brother banquet layer to absorb the water in the bonding layer, and also causes the bonding between the bonding layer and the base layer to be not firm. The strength of the base mortar is low, and the strength of the base is not enough.

The concrete wall is too smooth, the adhesive layer has no adhesion point with the base wall, and the friction is not enough, resulting in the formation of a hollow drum between the adhesive layer and the base layer. The adhesive layer mortar itself is too thick, and after the mortar is mixed, once it is in a static state, it will produce water leakage. After the floor tiles are pasted, the adhesive mortar will produce water leakage, which will form a water barrier film between the mortar and the floor tiles.

When the water is dissipated, the mortar is already in the final setting state, so it cannot form an effective bond with the floor tiles, resulting in hollowing.

3.Material Issues:

Different tiles have different water absorption. According to the requirements of the construction specifications, the tiles need to be soaked and moistened. However, the wetting is not sufficient or the wetting is not carried out by soaking water, which causes the tile to absorb water from the adhesive layer, causing the moisture in the adhesive layer to be insufficient, resulting in the adhesive layer and the tile surface not sticking firmly.

The cement grade is too low or the stability is unqualified, the density of the mortar is inconsistent, and the cement mortar settles after the completion of the initial setting period, resulting in hollowing and loosening between the base layer and the adhesive layer or the bonded silver layer and the tile surface.

What are the causes of hollow tiles? How to deal with tile hollowing?

Many people have encountered the problem of "tile hollowing" after decoration, and many decoration novices feel very puzzled about it, and do not understand why there will be problems just after decoration, so what is the reason for the hollow tiles? How to deal with tile hollowing? Let's take a look at the answers we will answer for you one by one.

What are the causes of hollow tiles?

1. When the tile is paved, the mortar is not full or the tile is not gently beaten and squeezed densely;

2. The tile is not soaked in water or soaked enough before paving;

3. 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.

How to deal with tile hollowing?

1. In the case of a large area of tile warping or hollowing, it is necessary to remove the tiles in the original warping or hollowing area, remove the original cement mortar layer, clean the base layer, and reapply the cement mortar.

2. If the tiles can no longer be paved and used, new tiles should be purchased, and it is recommended that the owners buy more tiles when buying tiles for the first time, in case of emergency.

3. If it is within the warranty period, find a decoration company (the base installation is generally 2 years).

Precautions when tiling and plaving:

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 the clear water; Check whether the plastering of the wall base meets the requirements, the stolen goods and dust of the wall base must be cleaned, if the stolen goods on the wall are not cleared, it will affect the paste effect of the tile, and in serious cases, the tile will fall off or the paste can not be excited; When paving, the back of the tile is covered with cement mixed mortar or 108 cement slurry and the wooden handle of a small shovel is tapped on the tile, so that the cement grout crowds the back of the tile, and then pressed hard to make the tile firmly combined with the wall base.

The above is what is the reason for the hollowing of the tiles brought to you? How to deal with tile hollowing? The contents of the mausoleum are all Ming Wangyan Department.

In home decoration, the proportion of ceramic tiles is relatively large, and many owners in the acceptance of ceramic tile paving at this stage, only look at the effect and flatness of its relatives, the most important point is ignored, that is, the tile hollow inspection. So, let's take you together to understand what are the reasons for the hollowing of tiles and what needs to be paid attention to when tiling.

There are many reasons for tile hollowing, such as construction errors, no gaps in the tiles, poor floor quality, material problems, and low cement labeling. Among them, the hollow drum caused by the construction error refers to the fact that the cement of the adhesive layer is not full enough during the construction process, so that the tile adhesive layer and the tile surface appear high and envy hollow, or there is no timely protection after the tile is paved.

Precautions for tiling.

1. In the process of paving tiles, the fit between the tile and the wall must be greater than the gravity generated by itself. Because the tile itself has many small holes, so it will be stronger in terms of water absorption, if the dry tile is used to pave, then it will absorb the moisture in the cement to dry, so that its fit is reduced, resulting in tile hollowing and falling off.

2. Before laying the floor tiles, it is necessary to deal with the ground socks, and the level is indispensable, only in this way can we understand the slope of the ground, so as to better control the paving effect of the floor tiles, and then determine the number of tiles that need to be used in each row and column according to the area of the ground and the size of the floor tiles.

3. If you use the supporting products of combined paving, you need to pay attention to their collocation. For example, the corrugated line is generally paved with dark tiles, but the antique brick also has a special matching corrugated line, which is mainly used around the ground or in the aisle entrance.
