Why do the tiles in my friend s house warp?

1.The reserved expansion joints are too narrow.

The ceramic tile and cement layer are greatly affected by temperature, and once the indoor temperature changes sharply, the ceramic tile and cement layer will change due to thermal expansion and cold contraction. If the expansion joints reserved between the tiles are too small, there will not be enough room to stretch when the tiles expand due to heat, which will cause the tiles to expand due to extrusion. Usually this situation tends to occur in the north when it is dry and has a large temperature difference.

2.The cement layer is too smooth.

Tiles are usually laid on top of the cement layer, and if the cement layer is too smooth and not haired, it can cause the tiles to warp.

3.The ratio error of the adhesive is large.

The tile and the cement layer are bonded by a cement, which refers to a mixture of cement and yellow sand that is blended in a certain proportion. If the ratio of the adhesive is very incorrect, such as the strength of the cement is too low and the yellow sand is too much, it may affect the adhesion of the tile and the cement layer, resulting in the tile warping.

4.Cement or adhesive is not evenly filled.

If the construction personnel do not fill the cement or adhesive evenly when laying the tiles, a lot of bubbles and gaps are left between the cement layer and the tiles, and these bubbles and gaps are due to the thermal expansion and contraction of the air, so that the tiles are bulged by the action of air tension when the weather changes, so there is a situation that the tiles are warped.

It should be that the process is not handled well when paving the floor tiles, and the cement or tile adhesive is not filled when paving, leaving more bubbles and hollow drums between the bricks and the ground cement, and the tiles are hollow and warped due to the thermal expansion and contraction of the air. It is recommended to choose a suitable tile adhesive and pave the tiles according to the correct construction process to avoid falling hollow drums.

Analysis of the reasons for the warping of floor tiles:

The paved ceramic tiles, made of clay firing, have the properties of thermal expansion and contraction, and may be the cement used in construction, which is a three-no product and is not within the qualified range. Let the tile not stick to the ground, there are gaps and hollows, and under the thermal expansion and contraction of the tile, it will be warped.

1. In the cold winter, the floor tiles shrink, or in a humid environment, the tiles are very easy to warp. In the process of laying tiles, the cement mortar is not mixed according to strict proportions, resulting in imbalance of proportions. If one of the cement and sand is put in more, after using it for a long time, the cement mortar loses its viscosity and produces a certain gap with the tile, which is easy to upturn.

2. Caused by poor quality of ceramic tiles, when we buy ceramic tiles, we can buy them in the large building materials market and consider first-line brands to buy. The quality is more guaranteed, and at the same time, it also reduces the occurrence of after-sales problems.

3. During the laying process, the gap reserved between the tiles is relatively small, and the temperature is relatively high when the indoor temperature changes, especially when the floor heating is turned on. If the gap between the tiles is too small, the tiles are heated or cold, and there is no space to expand and contract, and the tiles are easy to warp. In particular, the temperature difference in the north is relatively large, which is very easy to occur, and the south is relatively rare, due to the relatively large humidity.

Solutions for Cocking Floor Tiles:

1. The general arching solution is only part of the arching of the floor tiles in the general home, if it is not particularly serious, then you can find a suitable time to take it down for replacement, if you can't take it off directly, you can intercept it by using a cutting machine, pay attention to the fact that there will be a lot of dust when cutting, you can add a certain amount of water to the cutting machine.

2. All arching solutions: If all the floor tiles at home are arched, we must take them down one by one, and then write the logo on the floor tiles in each space, and deal with the flatness of the ground directly with tile adhesive.

There are two reasons for the hollowing of tiles: one is the settlement of the house, and the other is the change of temperature, thermal expansion and contraction.

Floor tile arching is divided into two categories: general arching and full arching. If all the arches can be taken down by hand, then write the number of each brick, so that it is convenient to remember the original position, keep the original direction of the floor tiles unchanged, and then scrape off all the cement mortar stuck to the side of the tiles. Wipe the cement mortar on the original bottom surface with a dry rag, and then coat the bottom surface with white glue for carpentry, and then arrange it up and compact it according to the number.

To repair a square meter of floor tiles, it is about a pound of white glue.

If only part of the arch up, some floor tiles can be taken down directly, and some can not be taken down, and the floor tiles that cannot be taken can not be pryed, and the hard pry floor tiles are broken, which is more troublesome and requires a cutting machine. The cutting machine cuts along the floor tile joint, a brick has four sides, and several need to be cut depending on the specific situation, some are afraid that all four sides will be cut, and some can cut two sides. After cutting, it usually takes an hour or two for the arched floor tiles to collapse naturally.

There is a lot of dust when cutting, and you need to constantly add water to the cutter.

The gap between the tiles is too small, the tiles appear hollow, and there are heating pipes under the tiles. With the change of cold and warm in the four seasons, the tile will produce a slight deformation with the temperature, if the gap between the tiles is small when laying the tile, it will cause the phenomenon of tile warping. When laying tiles, the cement slurry of the base layer is uneven, so that the force of the mud on the tile will be different, causing the phenomenon of tile hollowing, which will cause the tile to warp.

Another possibility is that there are heating pipes under the tiles, and the cement layer above the heating pipes is very easy to crack, causing the tiles to bulge.

I have only lived in a finely decorated house for 2 years, and the tiles have been warped, what is the problem?

See if the hollow drum is not good, and the quality of the tile itself is not good.

The tile is not good, and then it will warp.

The tiles that have been laid in the house suddenly warped, you can do the following:

First, the floor tiles are bulging

Reason 1, decoration paving floor tiles, fashionable atmosphere on the grade, a more popular ground decoration. There are so many advantages of floor tiles, but there are also some drawbacks in the construction quality, a small detail is not done well, or it is not done, it is easy to have some common quality problems. As if the questioner asked a question, the floor tiles bulge, and in this case, one tile arches up, squeezes against each other, and gradually the bulge appears.

Reason two, confirm the number of hollow drum tiles, the floor tile hollow drum stepped on the sound, some floor tiles hollow drum, step on the sound can not be felt, like this case, please professional, to test the number of hollow drum tiles, metal rod test hollow drum floor tiles, accuracy 100%, metal rod knock on the floor tiles, make an empty sound, indicating that the floor tiles are hollow, such as the sound of knocking on the floor tiles is more crisp, proving that there is no problem, confirm the number of hollow tiles.

Second, the floor tiles are hollow

Reason one, paving tile construction technology master, the process operation is not standardized, not in accordance with the order of paving the floor tiles, before paving the tiles, there is no trial paving, there is no expansion joint in the middle of the tile, the paste material is not suitable for the floor tile material, it is possible to cause the floor tile hollow, according to the actual situation, the floor tile hollow drum area, decide the back maintenance paving, there are two kinds of floor tile hollow drum, one tile back is very clean, the other mortar and floor tile fall off together.

Reason 2, according to the back of the tile, you can find out the reason for the hollowing of the floor tile, such as the hollow drum floor tile shovel down, the back of the floor tile is very clean, it should be the paving material, not suitable for the reason for the material of the floor tile, such as part of the adhesive mortar, and the floor tile together with the hollow drum off, should be paved when the floor tiles are paved, there is no corresponding gap, commonly known as "expansion joint", in the event of thermal expansion and cold contraction, the floor tiles squeeze each other, gradually supplied, and then a large area of hollow drum falls off.

3. Re-pave hollow floor tiles

Reason 1, confirm the reason for the hollow drum floor tiles, and then shovel off the hollow floor tiles, in the re-paving, cement mortar is not suitable for paving floor tiles, with tile binders, paving hollow floor tiles, clean the front and back of the floor tiles, or newly purchased floor tiles, the back of the release agent, must be cleaned, the release agent is particularly smooth, affecting the quality of ground paving, after cleaning, paving and sticking, paving the floor tiles in order, leaving the corresponding gaps.

Reason two, there is another situation, that is, the floor tile hollow drum area is very small, that is, the hollow drum of a few floor tiles, like this case, do not use tile adhesive paving, if the back of the tile is very clean, the adhesive mortar does not fall off with the tile, the back of the tile is cleaned, confirm that there is no moisture on the back of the tile, paste with the back of the tile, so it is relatively simple, the paving effect is very good, according to the situation to decide.

If the tiles are warped, we can buy some tile adhesive from the Internet to repair it, but we also need to use some cement before repairing, so that it can stick firmly.

I had to re-lay it, pry the tiles up again, and re-lay it, which was very troublesome.

You should find a professional decorator to re-repair or re-apply the tiles, observe the reasons for the tiles to warp, and then make appropriate adjustments.

It can be that the craftsmanship of the tile master is not good, or it may be that the flatness of the tile is not good. Like the Rongwang tiles in my home, there will be no such problem, and the flatness of his tiles is very good. If you don't understand, ask it.

The interior ground, floor tiles and the mortar bond of the base layer are not firm, and the outdoor road is mostly related to the design.

The process was not handled well when laying the floor tiles, leaving a gap after the floor tiles were laid. That is to say, when the cement or adhesive is not filled, there are more bubbles and hollows left between the floor tiles and the ground cement, which is the so-called void, in these voids, due to the thermal expansion and contraction of the air, the floor tiles are affected by the extrusion tension of the air when the weather changes.

Indoor floor, floor tiles and the mortar of the base layer are not firmly bonded. Outdoor roads are mostly related to design, because the space of the planted trees is smaller, the roots are shallow, and the rhizomes become thicker with the growth of the plums over the years, which promotes the change of the ground surface and the floor tiles will be warped; On the other hand, the ground foundation is not solid, or the phenomenon of fingering back will occur due to the poor bond between the mortar and the base layer and the tile.

Bathroom tile warping treatment method

1. First of all, you need to check the situation of the tiles, whether the tiles are several or large areas, and then use the hammer to knock one by one, if the sound is relatively empty, it indicates that the tiles have been separated from the cement layer, and the hollowing has occurred. At this point, pressing the tile down hard will cause damage. If a small tile can be picked up and re-laid, but if there are a large number of empty bricks, it can only be re-laid.

2. Then use the cutter to cut the warped tile, a lot of dust will be generated during the cutting process, remember to add a certain amount of water to the cutter, and then gently lift the tile, otherwise the tile will be broken.

3. Then scrape off all the cement mortar stuck to the edge of the tile, and then remove the cement layer under the tile, about 1-2 cm thick, and clean it.

4. Apply a layer of cement mortar, and be sure to apply it evenly. Cement yellow sand is mixed in a ratio of 1:3. If white cement is used, 108 glue can be used to glue the cement and floor tiles more tightly.

5. After the tile is laid, the cement can be reinforced, and the tile can be effectively avoided from being warped and cracked again.
