First, use high-quality materials When selecting materials, they must be purchased through regular sales channels, use qualified building materials and use them in strict accordance with the product instructions. At present, on the market, the general practice of decoration companies is: for the decoration of old houses, the decoration company will recommend that the owners first eradicate the walls before proceeding with subsequent construction; for the renovation of new houses, taking into account the developers have done a good job on the wall surface , If there is no special request from the owner, the decoration company generally adopts a local treatment method, that is, only the cracks in the existing base place are repaired. There are also insiders pointed out that in order to minimize the cracking of the wall in the future, regardless of new houses, old houses, it is best to completely 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. Third, 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 leveling process, 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. Fourth, pay attention to details of processing Cracks are easily generated at the joints of different bases and 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. In addition, 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. Professionals suggest that if every worker performs construction in strict accordance with standard processes, it will be able to minimize the occurrence of cracks in the later period. Fifth, 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.
