Whoever is responsible for the new house sticking bricks after falling off from the plastering layer

A few days ago, a few tiles suddenly fell from the house, but fortunately they didn't hit anyone, which scared me to death! There is no problem with looking very stable during acceptance, but when the wall tiles are removed, it is simply caused by not shoveling the wall skin. I can't find the person in charge of the renovation, where can I reason?

Look at this large area of white wall skin, how can the tiles be firmly pasted, and they can't be used for a long time! Therefore, you must remember to shovel the wall skin when sticking wall tiles, otherwise you will not be able to find anyone to reason with you.

I looked for a decorator again, and they said that they wanted to reinstall, because the area was too large, but now it was inconvenient to reinstall, so they temporarily used expansion screws to do a simple fix.

Here are a few reasons why wall tiles are used for a short time and are easy to fall off:

1. The quality of wall tiles.

The water absorption rate of wall tiles is directly related to the adhesion force, but it is not that the higher the water absorption, the better, if the moisture is not enough, it will be inconsistent with the cement shrinkage, which will lead to the falling off of the tiles.

2. The grassroots work has not been done well.

Underlying questions are often the most common. When we decorate a new house, we will shovel the wall skin, but most of us simply shovel or paint the wall. However, no matter how much the wall is brushed, if the wall skin is not cleaned, it will greatly affect the friction and adhesion of the wall.

Also, the wall is not watered enough, and the tiles are not cleaned properly, which will leave hidden dangers.

3. The tile is not dry and receives bumps.

When the cement mortar has not been completely bonded to the wall and is dry, it is best not to let it be collided, which will cause gaps in the mortar, resulting in unstable paste, and it may fall off in the future.

4. Gaps between tiles.

Gaps need to be reserved between wall tiles, because the effect of thermal expansion and cold contraction will cause them to squeeze each other, resulting in fracture or falling off. The cement mortar behind the wall tiles should not be too thick, which will not only affect the overall effect of the space, but also the thermal expansion and contraction will be very unstable, which will accelerate the falling off of the tiles.

Hollow drum: refers to the hollowing phenomenon between the floor, wall, ceiling decoration layer (plastering or pasting surface bricks) and the structural layer (concrete or brick wall) due to the unstable pasting and combination, commonly known as "two-layer skin". Hazards:

After a not-so-long period of time, the hollow drum part will fall off (or fall off) on its own.

Inspection method: plastering layer: with the naked eye**, the hollow drum part will generally be slightly higher than the overall plane around, and often accompanied by cracks, you can find that the inside is empty when you press it with your fingers.

Face bricks: Gently tap them one by one with a small hammer, and you can hear a hollow sound that is different from the sound of other parts, which is called "hollow drum" here

Tip: If the new house is hollow, it means that it is a quality problem, and you can ask the developer to rework it, or refund part of your purchase price. If the developer does not rework, you can file a complaint with the construction department.

The construction department will assign another company to rework, or deduct the project payment from the project deposit to compensate you for your losses.
