What causes cracked bathroom tiles?

There are three causes of floor tile cracking. The first is that the floor tiles were originally damaged, and people walked with weight after paving, resulting in the damage expanding and cracking. The second is that there is a hollow drum in the paving itself, and then under the action of people's inadvertent external force, such as the impact of hard objects, resulting in cracking.

The third cause of cracking is that the floor slab has cracked and the tiles have been pulled apart. However, the cracking of the floor slab will be relatively long, and only one floor tile will crack, which is obviously not the cracking of the floor slab, which can be ruled out, and can only be one of the first two reasons.

This phenomenon is very common, and I think the causes of tile cracking are:

The deformation of the floor of the new house (the prefabricated slab is stressed) causes the tile to crack, the cement prefabricated slab is not flattened and causes the tile to crack, and the cement below is not evenly paved when the tile is laid. The solution is to discard the broken tiles and replace them with them.

There are many causes of cracking, materials, processes, temperatures, etc., which are all possible and need to be analyzed and solved. The reasons for tile cracking are as follows:

Tile cracking caused by deformation of the wall can show regular cracks in the horizontal, vertical or diagonal directions.

Unqualified adhesive will also lead to problems such as hollowing and falling off after tile paving.

If the tile with a certain water absorption rate is not soaked in water before paving, the tile will absorb its moisture in the process of cement mortar coagulation and strength rise after paving, resulting in cement water loss and no adhesion, and the strength is reduced, and the adhesion of brick to cement or cement to the original wall is reduced, resulting in hollowing and falling off.

If there is no proper gap during paving, it will also cause the tile to be crushed, cracked, hollowed out or fall off.

Some inferior tiles are not hard enough, and if the load-bearing is too high during use, they are easy to crack (mainly referring to floor tiles).

Solution: You can use toothpaste to repair these cracks, gently squeeze out some toothpaste, and use your fingers to evenly apply the toothpaste to the cracks. Gently wipe off any excess toothpaste around you with a cloth or paper towel.

When it dries, the tiled walls look like new. If the tiles are colored, buy toothpaste of the corresponding color, or mix gouache paint in white toothpaste, and the effect of applying the gaps in the tiles is just as good. Cracks and scratches on the surface of the tile can also be repaired with white toothpaste, and the scratches on the surface of the tile will disappear after applying it a few more times.

Most of them are the following three points.

1. Wall deformation.

Tile cracking caused by deformation of the wall can show regular cracks in the horizontal, vertical or diagonal directions.

Precautionary measures: Before laying bricks on the light wall, ask the construction personnel to test the wall to see if the wall is installed firmly; Secondly, it is recommended to make a layer of steel wire mesh on the side of the wall tiles to improve the strength and load-bearing capacity of the wall. For the insulation wall, the insulation layer is usually made of polystyrene board material, and the original insulation wall can be removed and replaced by bricks (commonly known as foam bricks).

Due to the strong adhesion of the bricks, it can effectively reduce the cracking and falling off of the tiles, but the insulation effect will be slightly worse. It is also possible to hang a layer of steel wire mesh on the polystyrene board, and then use a cement pressure plate or a wave magnesium board to lay tiles on it.

2. There are no seams between the tiles.

If there is no proper gap during paving, it will also cause the tile to be crushed, cracked, hollowed out or fall off.

Precautionary measures: ceramic tiles and caulks will have thermal expansion and cold contraction, and appropriate gaps should be reserved when paving; Caulk is a flexible product with toughness and low strength, which makes up for the expansion coefficient of thermal expansion and cold contraction of ceramic tiles, and can avoid hollowing and cracking to a certain extent.

3. Poor quality tiles.

Some inferior tiles are not hard enough, and if the load-bearing is too high during use, they are easy to crack (mainly referring to floor tiles).

Precaution: Choose branded products. The hardness of the tile is directly related to the density, when purchasing, turn the brick over to see the back, the more delicate the particle of the tile density, the higher the hardness, the better the quality; You can sprinkle water on the back of the tile, if the water does not seep down and flows downward, it means that the tile is denser and harder; If water seeps down, it means that the tile is less dense and less hard.

Bathroom tiles, cracked because the quality of the tiles is not good, the longer the less durable.

First, the thermal expansion and contraction of ceramic tiles will lead to hollow cracking.

Second, uneven application of tile adhesive or poor quality will also lead to cracking.

Third, the quality of the tiles is not very good.

It is best to have tiled walls below the ceiling.

First, it looks good, especially the tiles with patterns, which work very well;

Second, waterproof, the bathroom is a place with more water, and tiles are easy to have a waterproof effect.

Thermal expansion and cold contraction, water absorption expansion, dry cracking, all may crack, the main thing is that the expansion joint is too small.

1. Unqualified adhesive: Unqualified adhesive will lead to problems such as hollowing, falling off and resistant, etc. after tile paving. Usually cement with mortar is in accordance with 1:

1 ratio to the ratio, if the ratio is uneven, the cement mortar can not achieve the required bonding effect; In addition, the use of inferior or expired cement will lead to problems such as poor adhesion and cracking of tiles.

2. Wall deformation: The cracking of tiles caused by the deformation of the wall will present regular cracks in the horizontal, vertical or oblique directions.

3. The tile is not soaked in water: if the tile with a certain water absorption rate is not soaked in water before paving, the tile will absorb its moisture in the process of cement mortar coagulation and strength rise after paving, resulting in cement water loss and no adhesion, and the strength is reduced, and the adhesion of the tile to the water mu celery mud or cement to the original wall is reduced, resulting in cracking and other phenomena.

4. There is no gap between the tiles: if there is no appropriate gap reserved during paving, it will also lead to the tiles being squeezed and cracked, hollowed out or falling off.

The above is the introduction of what is the cause of bathroom tile cracking, I hope Xingchang will help you.

Ceramic tile is the most common decoration material in our home decoration, and many people will find that the bathroom tile at home will crack after a period of use, which seriously affects the aesthetics. So, what is the cause of bathroom tile cracking? What are the tips for buying bathroom tiles?

Reasons for the cracking of bathroom tiles: 1. Unqualified paste: Unqualified tile adhesive will also cause cracking, hollowing and falling off of ceramic tiles, so it is necessary to strictly follow the proportion when proportioning.

2. Wall deformation: wall deformation will also cause the tile to crack, so it is best to make a layer of steel wire mesh on the first side before paving the wall tiles, so as to improve the strength and bearing weight of the wall.

Bathroom tile purchase skills.

1. When purchasing bathroom tiles, you can start from its surface, take out a tile at will to see whether its surface is smooth and intact, and whether the glaze is uniform and bright, whether there are spots or lack of glaze, if there are these phenomena, it means that there are quality problems in the tile.

2. When buying tiles, you can take one of them to knock on the other, if the sound of knocking is crisp and loud, it means that the quality of the tile is good, but if there is an abnormal sound after knocking, it means that there is a heavy skin or crack inside the tile.

3. When purchasing ceramic tiles, you can also use the method of dripping water to verify its texture, and drop water on the back of the porcelain closed bricks, if the water absorption is relatively slow, it means that the density of the tile is relatively large, and the quality is good. However, if the water absorption is fast, it means that the density is sparse and the quality is not very good.

Article summary: The above is about what is the cause of bathroom tile cracking and what are the skills for bathroom tile purchase, I hope to help you. In addition, it is necessary to remind everyone that in the decoration, the tiles used in each area are different from time to time, so it is best to determine the use area before purchasing.

Many owners will find that the new house has just been renovated, and the bathroom tiles suddenly crack, which not only seriously affects the owner's living experience, but also affects the overall aesthetics of the bathroom. So, what is the cause of bathroom tile cracking?
