The exterior wall tiles have fallen off in less than a month, and the peeling tiles have been separa

A few days ago, a few tiles suddenly fell from the house, but fortunately they didn't hit anyone, which scared me to death! There is no problem with looking very stable during acceptance, but when the wall tiles are removed, it is simply caused by not shoveling the wall skin. I can't find the person in charge of the renovation, where can I reason?

Look at this large area of white wall skin, how can the tiles be firmly pasted, and they can't be used for a long time! Therefore, you must remember to shovel the wall skin when sticking wall tiles, otherwise you will not be able to find anyone to reason with you.

I looked for a decorator again, and they said that they wanted to reinstall, because the area was too large, but now it was inconvenient to reinstall, so they temporarily used expansion screws to do a simple fix.

Here are a few reasons why wall tiles are used for a short time and are easy to fall off:

1. The quality of wall tiles.

The water absorption rate of wall tiles is directly related to the adhesion force, but it is not that the higher the water absorption, the better, if the moisture is not enough, it will be inconsistent with the cement shrinkage, which will lead to the falling off of the tiles.

2. The grassroots work has not been done well.

Underlying questions are often the most common. When we decorate a new house, we will shovel the wall skin, but most of us simply shovel or paint the wall. However, no matter how much the wall is brushed, if the wall skin is not cleaned, it will greatly affect the friction and adhesion of the wall.

Also, the wall is not watered enough, and the tiles are not cleaned properly, which will leave hidden dangers.

3. The tile is not dry and receives bumps.

When the cement mortar has not been completely bonded to the wall and is dry, it is best not to let it be collided, which will cause gaps in the mortar, resulting in unstable paste, and it may fall off in the future.

4. Gaps between tiles.

Gaps need to be reserved between wall tiles, because the effect of thermal expansion and cold contraction will cause them to squeeze each other, resulting in fracture or falling off. The cement mortar behind the wall tiles should not be too thick, which will not only affect the overall effect of the space, but also the thermal expansion and contraction will be very unstable, which will accelerate the falling off of the tiles.

Because the water absorption rate of ceramic tiles is low, the density of ceramic tiles and cement is different, so the expansion coefficient is also different, and the hollow drum will be formed after a long time.

The tiles and cement fall off together, how to solve it?

Dear, hello, I am glad to answer for you: the tile and cement fall off together, how to solve it? A:

If the tile and cement fall off, if it is a small area falling off, you can not plane the wall, directly paste with structural adhesive, or marble glue to paste, so that the height will not be too obvious. In addition, it can also achieve a strong paste. If a large area is planed off and redecorated, you can choose tile adhesive and the like to visit relatives is also very firm, you can use tile adhesive, its main feature is that it is more viscous and more water-resistant, and during construction, as long as the uniformity is coated with a layer of glue, you can pretend to be blind to fix the tile, and the operation is relatively simple; Compared with the traditional process, the use of tile adhesive will also be more affordable.

The specific operation step is to stir the glue and apply it to the back of the tile, and then apply the reed missing tile to the base surface. This pasting method is more likely to produce the problem of vacancy, which can easily lead to the problem of silver removal and empty fall of the tile in the later use process, so it is not recommended to use it.

Reason 1:

Improper construction process, resulting in tile falling off.

Among them, there are two reasons for improper tile paving:

1. Poor quality of mortar: the mixing ratio of mortar is inaccurate during construction, and the mixing is uneven. As a result, the sticking strength is not enough, which affects the bonding strength of the tile and the wall base, and finally causes the tile to fall off.

Solution: Replace with high-quality mortar.

2. The face brick is not compacted: the master's operation technique is wrong, and the force is uneven, so that the combination between the tile and the wall base is not enough. Or after pasting, in order to correct the deviation, the face tile is repeatedly moved, kneaded, and beaten will also cause the adhesive layer to be seriously damaged, and finally cause the tile to fall off.

Solution: The veneer brick should be firmly pasted.

Reason 2: The quality of the tiles is poor, which causes the tiles to fall off.

1. Quality problems: the water absorption rate of ceramic tiles should not exceed 18%, but the water absorption rate of many tiles has reached 20%, and the most has reached more than 25%.

Solution: Replace high-quality tiles.

2. Improper water immersion of tiles: due to the water immersion of the tiles is not in place, the paved tiles will absorb the moisture of the wall cement. As a result, the tiles and tiles are not firmly pasted and fall off.

Solution: Remove the moisture from the tiles.

There are many reasons why wall tiles can fall off, and it can be due to the long renovation of the house. It could be a problem with construction: 1

Grassroots treatment problems: the wall and ground base treatment is not clean, the watering moisture is not enough, the floating dust on the back of the tile is not removed, and there are too many water traces before paving, which will lead to the tile and the wall are not tightly bonded, and there will be loosening and falling after a period of use. 2.

Tile quality problem: The quality of the tile is also one of the reasons for loosening, and the water absorption rate of the tile directly affects the firmness of the paste. The state stipulates that the water absorption rate of porcelain tiles is E, and the shrinkage and expansion rate of porcelain tiles is about 4 10-6, when the water absorption rate of ceramic tiles or cement does not reach the standard, after the occurrence of thermal expansion and cold contraction, the shrinkage rate of ceramic tiles and cement is inconsistent and leads to separation and falling.

3.Construction process problems: during the construction process, if the cement mortar of the cushion is too thick or the cement is added too much water, the tiles will fall; In addition, if it is a large-size tile, if the seam is too small, the thermal expansion and cold contraction will squeeze each other, which is easy to cause warping and cracking.

4.Problems in daily use: the water absorption rate of the inner tile is low, if the tile is not fully fitted with the cement, it is subjected to a large impact force, such as trampling or the impact of hard objects, it is easy to cause the separation of the tile and the cement, and the bottom of the brick is hollow.

Generally, the tile falls off and can be repaired in the following ways: 1Corner hollow drums:

If it is found that there is a hollow drum on the edge of the tile after paving, the part of the partially hollow drum can be watered to avoid overall replacement. 2.Local hollowing:

If there is a small amount of partial hollowing of the tiles on the wall and floor, if it does not affect the installation of cabinets, mirror cabinets, showers and water heaters, etc., it can not be treated, but if it affects the installation and daily life, it is recommended to knock off the local tiles and re-pavement. 3.Large area hollowing:

If there are 2 3 tiles in the space, it is recommended to remove them all and re-pave.

Compared with the traditional cement yellow sand tiles, the MS glue tile effect saves the material cost of cement yellow sand, and the labor cost is also reduced a lot, and at the same time improves the construction efficiency, so I can move in early. Greenridge MS modified silane glue, all properties are excellent, sealing and waterproof, high and low temperature construction, the highest adhesion force reaches 30kg square centimeters. Moreover, Greenridge MS glue has zero formaldehyde, zero isocyanate, solvent-free, non-toxic and tasteless, and the VOC emission is far lower than the national standard, which does not damage the environmental performance of the substrate.

It has a wide range of adhesion to substrates, and most inorganic, metal, wood, concrete, ceramics, glass, stone, etc. have good adhesion properties. Good elastic deformation ability: high elastic deformation ability can ensure that the adhesive surface can adapt to various external tensile and compression deformation, absorb and compensate dynamic loads, evenly transmit the force, prevent premature fatigue of the material, and always maintain effective sealing and bonding.

Summary. Dear, the reason for you to find out that the exterior wall tiles fall off is: because the exterior wall tiles have been exposed to the atmosphere for a long time, subjected to wind, sun, rain, cold and heat and other changes, the tiles are sticky and cracked, hollow, peeling, and the wall cracks occur in the joint layer.

Or the ambient temperature is relatively high during the tiling construction, the wall bricks and the base layer are relatively dry, the concrete layer loses water quickly, and the bonded cement is not properly hydrated, resulting in the failure of the adhesive layer in the later stage and falling off.

Exterior wall tiles fall off, dear, for you to inquire about the reason for the exterior wall tiles to fall off: because the exterior wall tiles have been exposed to the atmosphere for a long time, subjected to wind, sun, rain, cold and heat and other changes, the tiles are sticky cracking, hollowing, peeling, and wall cracking occurs in the joint layer. Or the ambient temperature is relatively high during the tiling construction, the wall bricks and the base layer are relatively dry, the concrete layer loses water quickly, and the bonded cement is not properly hydrated, resulting in the failure of the adhesive layer in the later stage and falling off.

The solution is as follows: carry out splicing, surface treatment: remove oil, dust and loose objects from the work surface, clean the tile gaps, and make sure that there is no debris and water. The caulking is made of a flexible waterproof material that absorbs deformation and increases the impermeability of the topcoat.

The walls of the houses in the community have fallen off many times, and the community has only been simply inspected and repaired each time. This year, the wall fell off again, and the property was restored to have passed the warranty period, which required the owner to refer to the way of other owners. Because 60% of the owners need to agree to use the maintenance**, is it reasonable?

Wait a minute, I'll check it for you, because this has already involved the legal aspect.

Dear and dear for you, we will find out that the developer will repair or compensate the owner's house during the warranty period; However, if it is not within the warranty period, the funds for the repair of the exterior wall still have to be borne by the owners of the entire building.

You can consult a legal professional for details, because I am not a professional after all, sorry.

Exterior wall tiles will inevitably appear after a long period of wind and rainExterior wall tiles peel offphenomenon. When encountering the phenomenon of exterior wall tiles falling off, we must take remedial measures in time. Let's talk about the solutions to the falling off of exterior wall tiles, as well as the skills of maintaining exterior wall tiles, let's learn about it together.

1. What should I do if the exterior wall tiles fall off?

1. Remove the broken wall tiles.

If the wall tiles do not fall off completely, first use a cutter to cut a 5-6mm groove around the broken wall tiles, and then use a cutter to scrape off the cement on the wall tiles. Then paint a glaze on the surface of the wall tiles, which makes it easier to break the wall tiles. If the cement sticks too hard, broken wall tiles can be removed with hammers and other tools.

2. Only the tiles fall off, and the mortar does not fall off.

If the tile comes off, but the mortar does not come off, first clean the mortar on the tile, then use 107 glue and an appropriate amount of cement to stir until it is paste, then use it to apply a thin layer on the film. The back of the tile. Finally, paste the tiles back to their original position, and the strength should be moderate when pasting.

3. The tile and mortar fall off at the same time.

It is also common for tiles and mortar to fall off at the same time. In this case, first cut some small pits in the area where they fell, and then reattach the tiles with 107 mortar. During the pasting process, it must first be pressed and waited until the mortar hardens before it can be removed.

4. Paste the new wall tiles with the sail height.

If the tiles are peeling, you can buy new tiles and stick them. First of all, buy tile adhesive, mix it evenly in proportion, use a tool to wipe off the glue, then align the colors with wall tiles, and gently tap the tiles with a hammer. In this way, the internal air can be knocked out, allowing the tile and glue to bond better, but this method is suitable for small areas of tile shedding.

Secondly, glass tile adhesives cannot be chosen when choosing a tile adhesive because they are more suitable for use on a single flat surface.

Second, what to do if the exterior wall tiles fall off - how to maintain the exterior wall tiles.

First, when cleaning exterior wall tiles, you can use a broom to clean fine sand and gravel dust from the surface, and then wipe and wipe the exterior wall tiles with a clean cloth.

Second, if there is a residual protective agent on the surface of the exterior wall tiles, it can be removed with talcum powder on the brick surface, and then wiped back and forth with a cotton cloth. After construction, it should not be cleaned with high pH or corrosive cleaning solvents, because the chemical properties will damage the protective layer on the surface of the bricks, and the anti-fouling performance will be reduced.

Thirdly, if the exterior wall tiles are coated with coffee, tea, etc., they should be treated immediately, otherwise it is easy to penetrate. After treatment, you can apply bleach to the dirt, cover it with plastic wrap the next day, and wipe it off with water.

Fourth, for stubborn stains on exterior wall tiles, you can use stain remover, stain remover or car wax, etc., and wipe it back and forth with a clean cotton cloth until it is dry.

Don't panic when encountering exterior wall tiles falling off, refer to the above solutions to introduce to you, there is to regularly maintain the exterior wall tiles, regular maintenance and cleaning, which can effectively prevent the exterior wall tiles from falling off, increase the service life of the exterior wall, I hope it can really help you.

This is related to many factors, such as the quality of construction, the local climatic conditions, the type of cement selected for construction, or the quality of the adhesive, etc., which cannot be generalized. It may be a problem with the quality of construction, and the exterior wall tiles are not covered with mortar or adhesive during construction, and they may fall off after a long time. It is also possible that the quality of the exterior wall is not well controlled when painting, and the stucco layer is hollow, cracked, and has no adhesion, causing the outer layer of the surface brick and the stucco layer to fall off together.

At the same time, it is also related to the local climate, the quality of the adhesive or mortar used in the construction. However, it is generally the case, if the exterior wall is constructed with exterior wall bricks, try to design a canopy or an outward podium on the first floor or upstairs to minimize the serious consequences caused by the falling off of the exterior wall tiles. As for the prohibition of the use of surface tiles on exterior walls, I have not heard of it, because any kind of construction process is nothing more than a problem of quality control, as long as the quality control is controlled, many problems will not happen.

As long as the quality control is lived, the problem of the brick falling off can also be controlled, and the brick is also very beneficial to the leakage of the wall, and the exterior wall paint is easy to seep. So it's impossible to say that the high-rise is not allowed to use exterior tiles, as the guy upstairs said. At least at this stage, the Chinese authorities will not make such a request.
