Is tile hollowing a common problem when home improvement acceptance?

Yes, tile hollowing is a common problem when home improvement acceptance, because tile hollowing is a relatively common phenomenon, which will also cause the effect of home improvement to be affected.

Yes, so when checking for renovation problems, be sure to pay attention to these things, and be sure to knock on the wall with relevant things.

Yes, because such an architectural style is not up to standard at all, such a home decoration effect is particularly poor, and it is a cutting corner.

Summary. Hello, tile hollowing is a construction problem, and the tile itself is not necessarily related. The reasons for this problem are:

1. The wall is too dry, and the moisture is absorbed too quickly. 2. The time for the tile to soak in water is not enough, or after taking it out of the water, the water control time is too short, and there is too much moisture in the tile. 3. The cement slurry is not evenly scraped in batches, and the compactness is not enough.

4. There are problems with cement or tile adhesives.

Hello, tile hollowing is a construction problem, and the tile itself is not necessarily related. The reasons for this problem are generally: 1. The wall is too dry and the moisture is absorbed too quickly.

2. The time for the tile to soak in water is not enough, or after taking it out of the water, the water control time is too short, and the water in the tile is too much. 3. The cement slurry is not evenly scraped and the compactness is not enough. 4. The cement or tile adhesive itself is cracked.

Hello, 1.The expansion gap between the floor tiles and the walls around the floor tiles and the walls around the floor tiles is too narrow, and when the room temperature changes drastically, the floor, cement layer and tiles will appear to expand and contract. If the gap is too thin and there is not enough space for the tile to "stretch", the tile is easy to arch, which is generally easy to appear in the northern region, while the south is not easy to appear due to the high humidity and small temperature difference.

2.It is that the tiles are not mixed with cement and yellow sand in the correct proportion. If the cement grade is low, the yellow sand is put too much, and after a long time, the cement in the lower layer will not be bonded to the floor tiles by the bridge front method, resulting in the upturned floor tiles.

3.Another relatively rare reason is that if the original cement floor is very smooth, it is easy to arch the tiles when there is no haired potato to lay tiles.

There are many reasons for tile hollowing, such as construction errors, no gaps in tiles, poor ground quality, material problems, and low cement markings, etc. 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 tile adhesive layer and the tile surface are hollow, or there is no timely protection after the tile is paved and trousers. 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 in terms of water absorption performance will be relatively strong, if the use of dry tile to pave, then it will absorb the moisture in the cement to dry, so that its fit is reduced, resulting in tile hollowing and missing and falling off. 2. Before laying floor tiles, the ground should be treated, and the level measurement is an essential item, 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 according to the area of the ground and the size of the floor tiles, the number of tiles that need to be used in each row of each volt row is determined. 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.

There is a danger that the wall hollow drum is not handled. If the wall hollow drum is not dealt with in time, the hollow drum area will become larger and larger after a long time, and then cracking, peeling and other phenomena, and may fall off at any time, and even smash items and even hurt people, which has great potential safety hazards, and the price of repairing the wall hollow drum is higher, because the adhesive and the substrate wall are very firm, not easy, usually use special adhesive resin glue, the cost is very large, if there is a brick damage, it needs to be replaced, the cost is greater.

The hollow drum of the wall also has an impact on the later decoration, the hollow drum place will first appear cracked, and then after a long time due to the force, the stucco layer at the crack will begin to fall off, if it appears in the sub-balcony or window sill and other places, it will even cause water seepage, which will not only affect the protective effect of the wall, but also affect the overall decoration effect.

How to deal with hollow walls1. The mortar wall is hollowClean the hollow drum first, moisten the wall with water, and then repair the wall with cement mortar.

2. The concrete wall is hollowUse a blade to remove the hollow drum directly, and then apply a layer of concrete interface agent to the wall.

3. Paint the wall hollowRemove all the dust and then patch the walls with putty powder. Shovel off the foam part, look at the cement wall, if it is serious, shovel off the cement wall, rinse with waterproof paint, then scrape the cement mortar, seal the bottom with waterproof paint or interface agent with waterproof and moisture-proof function, scrape the putty after drying, and then polish and brush the primer and topcoat.

1.The thin slurry method has high requirements for the leveling of the wall foundation. If the base layer of the wall is uneven, the undulation will make the tile contact with the wall incomplete, resulting in hollowing.

If the strength of the foundation wall is not enough, there are oil stains, loose base layer, etc. It will also directly affect the adhesion of tile adhesive, resulting in hollowing or even falling off of the tile. Do not fully contact with the tile wall, if the flatness is not enough after pasting, the tile surface will be cracked, porcelain, hollow, and falling off.

Bricks of different sizes should be scraped flat with different types of tooth trowels, and the flatness should be adjusted by rubbing in place when paving, and the joints should be hooked after 24 hours of paving.

2.The acceptance of home improvement tiles is to check whether there is a hollow drum. The inspection method is usually to use a special small steel hammer or hammer to strike the corners and middle of the floor tiles around the room to check whether the floor tiles are empty.

If the sound is crisp, it is normal; The void is hollow. If a hollow drum is found, it must be removed and replaced. The hollowing of the tiles is largely caused by improper construction.

When paving ceramic tiles, the cement mortar in the cement mortar bonding layer is too thin, the cement mortar is dry during paving, and the pollutants on the back of the board are not removed. It may cause the tiles to hollow. Therefore, in the construction, it is necessary to prevent the occurrence of hollowing, and the mortar of the adhesive layer should be dry and easy to fall to the ground.

3.The slope of the surface of the floor tile should meet the design requirements, and should not be soaked or stagnant, and the connection with the floor drain and the pipeline should be tight and firm, and ensure that there is no leakage. The floor tiles of the bathroom should have a certain slope, and the floor drain in the middle must be at the lowest point of the bathroom floor.

During acceptance, it can be determined whether the floor drain is at a low point by measuring whether the distance from the horizontal baseline of the floor drain position to the floor tile is the largest. It is necessary to pay attention to whether the floor tiles are empty. The floor tiles must not be hollowed, which will shorten the service life of the floor tiles.

4.Always, simply hit each tile with a wooden or rubber hammer. If the sound is dull, it means that the floor tiles are relatively firm and firm, and there are no hollow drums.

However, if there is a crisp knocking sound, it means that the floor tiles are not paved and there is a certain hollowing phenomenon. The acceptance standard of floor tiles is that the hollow drum of the floor tiles should be within 3%, and the hollowing phenomenon of the main passage is absolutely not allowed. The construction of floor tiles is actually very simple, especially for some skilled renovation workers, and the efficiency is very high.

However, in order to catch up with the construction period, there may be unqualified quality, so it will be found that the floor tiles may be empty later.

If the sound of percussion is relatively dull, it means that the paste is more firm, if it is a crisp sound, it means that the paste is not firm, and there may be a hollow drum phenomenon.

You can find a professional surveyor to take measurements, so that you will have a clear judgment. A 5-point percussion test is also available.

It can be judged by the sound of percussion, if the sound of percussion is relatively empty, then it means that the tile has a hollow drum.

First, how to deal with the problem of tile acceptance hollow?

2. Conclusion.

In such a situation, I think we must communicate with the decoration team in a timely manner, and then we should also re-lay the tiles, choose some better quality tiles, and then we should also pay attention to the use of some beauty sewing agents, so as to better deal with this problem.

Choose to re-tile, or you can add some cement to the hollow place, or you can apply some beauty cream on it, or you can use direct sunlight to tile back and forth to alleviate it.

Let the renovation company redecorate, or let the decoration company compensate, and then find a new worker to carry out the construction, and remove the hollow tiles and reinstall them.

Under normal circumstances, after the tile is paved, the brick and the wall should be completely filled by adhesive materials such as cement mortar or tile adhesive. However, sometimes due to material or construction problems, the back of the tile and the wall are not completely filled, and there is a hollow or empty shell, which is called "tile hollowing".

1. What are the dangers of tile hollowing?

A small number of hollow tiles may not be harmful, but if the hollow area is large, it will cause the tiles to not stick firmly to the ground or wall, and it is easy to warp from the ground or fall off the wall. In actual cases, the tile hollowing drum often has a joint effect, after a brick hollow drum is loose, the surrounding tiles will gradually become hollow, and finally the tiles of the entire floor or wall will be warped or fall off. Tile hollow drum falling off not only affects the appearance and use, but also causes potential safety hazards, high hollow drum tile falling off is easy to smash people, the consequences are very serious.

Second, what is the cause of tile hollowing?

There are many cases of tile hollowing, but it can be boiled down to two categories: after using inferior tiles, cement, back-coated adhesive or tile adhesive and other materials, the tiles are likely to slowly appear hollow and fall off in the later stage. Most of the tile hollowing is caused by bricklayer construction problems, and the 4 most common are:

One is that the tiles are not soaked sufficiently. If the wall is covered with porcelain tiles, it should be soaked for 12 hours, and it must be soaked in clean water, not dirty water; If it is a glazed tile, it should be soaked for at least 2 hours to allow the tile to absorb enough water to avoid the problem of hollowing.

The second is that the ceramic tile base is not clean. When the tile leaves the factory, there is usually a layer of white release agent on the back, which must be cleaned; In addition, if all kinds of dust on the construction site are contaminated on the tile base and paved without cleaning, it is easy to cause the hollow drum to fall off in the later stage.

The third is that the mortar ratio is wrong. The ratio of cement, water and sand in cement mortar is standardized, if the bricklayer does not come according to the requirements, the sand is more and the cement is less, the adhesion is low, and the probability of hollowing is high; In addition, if the mortar is stirred too thin, a large amount of sinking after being put on the wall is also easy to cause the problem of hollowing.

Find an experienced bricklayer. Since most of the hollow drums are caused by non-standard construction, it is too important to find an experienced bricklayer master to apply tiles. A good bricklayer can paste ordinary tiles very standard and high-end, but a bad bricklayer will paste the tiles you bought **.

Do a good job of supervision. When paving tiles, the owner must be present in a link, but all experienced bricklayer masters, know how to avoid the generation of hollow drums, but they are afraid of encountering the kind of irresponsible workers, bent on saving trouble and trying to do the work of your home as soon as possible to the next house, so in the paving does not comply with the norms, and eventually causes the tile hollow.

In the process of tile acceptance, if the tile is found to be hollow, the whole tile needs to be re-pasted to prevent the tile from cracking and deformation in the future.

Then you should report such a problem to the master, it is best to let them deal with it as soon as possible, and the tiles should be removed, and then the tiles should be re-applied.

Use a small iron rod to tap each tile, and judge whether the tile is hollow by the sound of the tapping. If the sound of percussion is dull, it means that the paving is more solid and firmer. On the contrary, if there is a crisp sound of "dong dong", it means that the wall and floor tiles are not firmly paved and there is a hollow drum.

If there is a hollow drum in the corner of the wall, we need to shovel the gaps around the tiles, and then pour them with relatively thin cement and knock the tiles while pouring, so that the cement slurry can penetrate completely. This treatment saves time and effort, and is not easy to cause damage to the tiles. If there is a hollow in the middle of the tile, it is necessary to pry the tile off and re-lay it.

Specifically, it is necessary to smash from the middle part of the tile, but not directly from the middle, you can use a small rhinestone to open a hole first, and then use a tool to slowly spread to the surrounding way to pry open the tile, to avoid damage to the surrounding tiles.

1. The hollow drum of each brick cannot exceed 20%, and there can be no hollow drum in the middle position. When laying on the ground, the total hollowing ratio should be ensured to be less than 5%, and the hollowing phenomenon is not allowed, otherwise it must be rebuilt.

2. We can use a small rubber hammer to knock on each floor tile on the ground, and we can know whether there is a dent through the sound, if the sound is muffled, then the degree of adhesion of the floor tile is very high, and the sound of "knock, knock" means that the floor tile is not laid well, and there is a hole.

3. After the floor tiles are laid, whether there are any cavities can not be checked immediately, and the acceptance should be completed within 24 hours. We can use a small hammer to strike on the tile surface to make it make a sound, indicating that it is empty. In addition, pay attention to whether there are scratches and damages on the surface of the floor tiles, and use tools such as rulers and two-meter rulers to observe whether the corners and surfaces of the floor tiles are flat.

Experts said that in the production process, we need to soak the tile first, wait for it to completely absorb the water, and then dry it, and then paste it after it dries for half an hour, otherwise the pasted tile will absorb the moisture in the adhesive, resulting in a decrease in viscosity and a hollowing phenomenon. Some tiles on the market are seamless tiles, but because the tiles are stones, its thermal expansion and contraction are inevitable. Most construction workers soak the tiles in water and then stick the tiles to the wall, so that the tiles will be covered with dust and easily produce bubbles, in order to prevent this phenomenon, they need to be rinsed with clean water and then attached to the wall.

Many floor tiles have a mesh pattern behind them, and the function of this pattern is to strengthen the combination of floor tiles and walls, so when buying floor tiles, you must choose a well-textured floor tile, so as to reduce the probability of a hail base hole.
