Small cracks suddenly appeared on the newly renovated snow-white walls, and the dark cracks looked particularly glaring on the white walls, which would annoy everyone. So why are there small cracks on the wall? Next, the editor will bring you information about how cracks on the wall are produced, let’s take a look together.
1. If there are cracks in a large area, chisel the base of the wall at the crack into a “U” shape, the distance between the “U” grooves is greater than 20CM, and roughen the chiseled base, and then hang the steel wire mesh.
2. After cleaning the base of the wall surface, first paste a layer of Dacron cloth, kraft paper or newspaper on the wall surface, and use the tension of the fiber to ensure the integrity of the latex paint film. This method is relatively simple and easy to implement, but the effect is average.
3. Remove the insulation board on the surface of the wall, or remove the cement wall, install a layer of gypsum board or “five-centiboard” on the outside of the insulation layer, and then apply latex paint on it. This method can remove all the irregular cracks, and the cracks are generally the joints between the plates, which are easier to deal with. However, this method is expensive and difficult to construct.
4. Use flexible decorative materials. At present, there is a kind of “elastic putty” that can make up for the problem of wall cracks to a certain extent. Some kind of wall paint can also play the role of covering small cracks on the wall. However, these materials themselves have less “elasticity” and will not work on walls with severe cracks.
5. Some consumers simply remove the insulation layer of the wall. Although this method can be done once and for all, it will reduce the thermal insulation and heat insulation performance of the wall, so it is not recommended for you to use it.
6. The wall of the construction hole in the civil engineering is post-built. If it cannot be naturally connected with the original wall, cracks will occur. Therefore, the bricklayer must plaster the joints in the wrong way, otherwise the painter will not be able to completely fit the cloth. Solve the problem of cracks.
7. After the decoration of the living room is completed, a basin of clear water can be placed in each room to maintain the humidity of the indoor air, which can effectively prevent the cracking of the wall.
The above is the relevant information about how the wall cracks are brought about by the editor, I hope it can be helpful to everyone.
