Causes of wall cracks

There are many causes of wall cracks, but they can be divided into two categories. One is caused by the structural problems of the building itself. Wall cracks caused by this cause are generally straight and relatively deep. Usually, construction workers will deal with the cracks in the building wall, but it cannot guarantee that there will be no cracks in the future.

The other type is caused by using inferior materials or adopting a non-standard construction process. The wall cracks generated in this case are generally cracked and their depth is slightly shallower than the former. In the construction process, the strict control of the quality of building materials and the tight control of the construction process can be used to minimize the occurrence of such wall cracks and kill them in the “cradle”.

How to avoid cracks

1. Use high quality materials:

Experts suggest that when selecting materials, they must be purchased through formal sales channels, use quality-qualified building materials, and strictly follow the product instructions.

2. Reasonably deal with the original wall surface

At present, the general practice of decorating companies on the market is: for the decoration of old houses, the decoration company will propose that the owners first remove the walls before proceeding with the follow-up construction; considering the renovation of the new houses, considering that the developers have already done a good job for the walls, If the owner does not have special requirements, the decoration company generally adopts a local treatment method, that is, the repair treatment is only performed at the cracks in the existing primary layer.

There are also insiders pointed out that in order to minimize the future cracking of the wall, whether new homes, old houses, it is best to fully eradicate the original wall. Because, if the quality of building materials used in the original basement of a new house is not good or shoddy products, it will cause the follow-up coating and the grass-roots layer to bond loosely, resulting in wall cracks.

However, the large amount of construction work required to remove walls is expensive, and the owners of many new houses are generally reluctant to choose such construction methods in order to reduce their decoration expenses, thereby increasing the possibility of cracks in the renovation of new houses.

3. Strictly control the construction process

The standard steps of blank wall brushing are: brush the interface agent → wall crack treatment → gypsum leveling → applicator → scrape 2-3 times putty → sanding → brush primer → repair and polish → brush twice.

The interface agent is an adhesive that acts as a curing and bonding agent. When applying, a small amount of water may be added according to the manufacturer's instructions. However, if water is added excessively, it will cause cracks in the wall surface in the future, and in severe cases, wall peeling and even peeling may occur.

In the process of leveling, it cannot be leveled once, but it should be divided into multiple times. Where there is a large error, it is generally leveled with gypsum and then leveled with putty 2-3 times. The leveling layer is not firm or smeared unevenly, which can easily cause cracks in the wall surface in the future.

For non-load-bearing walls, it must be wall-wide. Try to choose good quality wall coverings and white latex so that the crack prevention effect will be better.

4. Note the details of processing:

Cracks are easily generated at the joints of different bases, so special treatment is required during the construction process. For example, the joints between a wooden frame and a wall in a closet, if not treated, are likely to crack after four seasons. In the construction process, the method of inlaying the wood is generally used to mask the cracks that may be generated.

Improper repair of walls after slotting can also cause cracks in the walls. Theoretically, the cement mortar used for repairing and grooving should be the same as the proportion of building wall cement. This is difficult to achieve in actual operation. Therefore, cement mortar with a ratio of 1:3 is generally used for backfilling during construction and is used for slotting. Apply cloth or kraft paper to avoid wall cracks caused by shrinkage of cement.

Experts said that if every worker is in strict accordance with the standard process of construction, it will be able to minimize the occurrence of cracks in the later period.

Matters needing attention after construction

Sudden changes in temperature and humidity will be the cause of wall cracking. Therefore, experts suggest that after the renovation is completed, proper ventilation should be provided to the living room. If the room is kept in a closed state, the moisture in the decoration materials cannot be volatilized, resulting in a high ambient temperature and high humidity. After occupancy, the air is suddenly ventilated, and the water in the living room is rapidly reduced, which easily results in cracking of the wall. Of course, ventilation should not be excessive.

Maintaining normal indoor temperature and humidity, combined with high-quality finishing materials and standard construction techniques, will minimize cracks.
