What is the reason for the wall tiles in the bathroom to burst out?

The tiles pasted with broken corners, warped edges, and fractures are related to the wall, brick and process.

1. The reason for the wall.

If there is self-cracking in the wall itself, the stress is transmitted outward to the tile, which will cause the tile to deform.

A similar problem arises when the deformation of the tile itself cannot withstand it.

Problematic walls are usually marked before tiling, such as cracks, joints of two different wall materials, etc.

2. The reason for tiles.

Many inferior tiles do not guarantee that each tile is uniform, and there is a problem of distortion in itself.

Because China's walls are generally uneven, they are generally used to stick bricks by the back paste method, and there will be a lot of stress in order to be able to twist and flatten these bricks that have problems when pasting.

These stresses will gradually be released, causing similar problems.

3. Process problems.

The cement and sand used to paste the tiles and the ratio are also very important. The cement shrinks as it dries, and if the force of the shrinkage is too great (too high a grade chosen), the resulting stress is released onto the tile, causing damage to the tile.

In addition, there are problems such as hollowing on the back, which can also lead to excessive local stress strength, but this generally appears on the corners.

For the tiles that have already had problems, they need to be knocked off as a whole, and then by observing the wall under the tiles to determine what kind of situation it belongs to, and then carry out targeted rectification.

The reason for this is that there may be a problem with the quality of the tiles and the shrinkage rate is large. Second, the wall may be deformed due to foundation factors, resulting in damage to the tiles. The third is the sand ash used for pasting tiles, and the sand is too muddy.

The difference between the expansion and contraction rate of bricks and walls is too great, because the bricks expand and squeeze each other due to temperature or moisture.

1. Is it the time of paving, and the bricks are not soaked in water?

2. When paving, the ash joints are left small, and the cement will heat up and crack after the bricks are paved, 3. The foundation will fall and crack.

There may be problems with both bricks and walls, so it is recommended to find a master to take a look.
