The reason for the cracking of the bathroom wall tiles soon after the renovation

1. If there is a burst and protrusion on the surface of the tile, it must be a problem with the quality of the tile.

2. The overall protrusion of the ceramic tile is that there is a problem with the bonding or the base layer, the reason may be that the base is not well textured, the adhesion is not enough, or there is a problem with the bonding mortar and construction technology (the brick is not soaked in water in advance, and the later maintenance is not enough), and it will fall off after a long time;

3. If the crack is not accompanied by the phenomenon of falling rock dry and protruding, it should be caused by the deformation of the wall, there are two reasons, one is that the construction speed is fast, and the plastering and tiling work is completed before the wall does not reach stability, and the crack is generally irregular; The second is that the sealing quality of the wall is not good after slotting, and after a period of time, the plugging mortar shrinks at the slotting place to produce cracks, which are generally in the slotted part, and are more in line with the slotting route.

4. The problem of waterproof height of jujube search: if the base layer is handled well when tiling, whether there is waterproof should be consistent, so this problem is still the problem of Article 2.

If the tile cracks, another reason: artificial, water absorption There are two reasons There is no other exclusion of artificial, that is, the cracking caused by the water absorption of the tile, the general tile surface is made of porcelain will not absorb water, and the water vapor will only penetrate through the joints between the bricks and bricks, and the probability of cracks in the bricks of a few dollars is the largest, because the soil used when it is fired will not have this problem.

If there is a burst and protrusion on the surface of the tile, then it is a problem with the quality of the tile; If the crack is not accompanied by the phenomenon of falling off and protruding, it should be caused by the deformation of the wall, there are two reasons, one is the construction speed is fast, and the work of plastering and tiling is completed before the wall does not reach stability, and this crack is generally irregular; The second is that the sealing quality of the wall is not good after slotting, and after a period of time, the plugging mortar shrinks at the slotting place to produce cracks, which are generally in the slotted part, and are more in line with the slotting route.

1. The ratio of cement and yellow sand is wrong, and the tile will crack after shrinking more cement; 2. The quality of the tiles is problematic or there is no sufficient water invasion!
