What happened when the tiles on the wall fell off?

A few days ago, a few tiles suddenly fell from my home, but fortunately I didn't hit anyone. I was scared to death! When it was accepted, it looked flat and there was no problem, but when the wall tiles were demolished, there was simply no shovel. I can't find the person in charge of the decoration. Where can I argue?

Look at this large area of white wall skin and tiles. It won't take long at all! So be sure to remember to shovel the wall brick, otherwise you will be trapped and no one will be reasonable.

I also asked a decorator to have a look. They said that it would be reinstalled because the area is too large, but it is not convenient to reinstall now, so I temporarily fixed it with expansion screws.

The following are some reasons why wall tiles are easy to fall off after a short service time:

1, quality problems of wall tiles

The water absorption of wall tiles is directly related to the adhesion, but the higher the water absorption, the better. If the water content is not enough, it will be inconsistent with the shrinkage of cement, resulting in the tile falling off.

2, grassroots work is not done well.

Basic problems are often the most common. When we decorate a new house, we will shovel the wall, but most people just shovel the wall or paint it. However, no matter how the wall is fixed and the wall skin is not shoveled clean, it will greatly affect the friction and adhesion of the wall.

There is not enough water on the wall, and the tiles are not cleaned in place, which will leave hidden dangers.

3. The tiles will bump when they are not dry.

When the cement mortar is not completely bonded to the wall and dry, it is best not to let it collide, which will cause cracks in the mortar, make the paste unstable and may fall off in the future.

4. Gap between tiles

Gaps need to be reserved between wall tiles, because they will squeeze each other under the action of thermal expansion and cold contraction, leading to fracture or fall off. Don't use too thick cement mortar behind the wall tiles, which will not only affect the overall effect of the space, but also be unstable when it expands with heat and contracts with cold, which will accelerate the falling off of the tiles.
