Cracks in the walls of new homes are a common decoration problem. There are many reasons. It may be that the wall is too thin, it may be that the cement paint was applied before the wall was completely dry, it may be a structural problem with the original building, or it may be too stuffy in the top-floor residence, etc. It’s best to work with the decoration company or construction personnel to find out the cause. Of course, if there are too many cracks that cannot be repaired one by one, there is a better remedy. You can go to the market to buy linen cloth specially designed for paint, stick the linen cloth to the wall with white glue, and then apply cement after it is dry. Paint, in this case, can generally ensure that the wall will no longer have cracks and play a role in strengthening the wall.
Wall cracks are mostly caused by cracks in the cement of the wall, cracking of the joints of the wall’s “insulation boards”, or the cracking of old and new walls. Cracks appear at the joints, or cracks occur at the connection between the trunking and the original wall after the plumbers opened the grooves. Most of them are not quality problems of the decoration, but insurmountable defects in the construction. In order to pursue the decorative effect, decoration can be used to make up for construction defects:
1. If cracks appear in a large area, cut the base of the cracked wall into a “U” shape shape, the “U” groove spacing is greater than 20CM, and the chiseled base is roughened, and then the steel wire mesh is hung.
2. After cleaning the wall base, first paste a layer of solid cloth, kraft paper or newspaper on the wall, using 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 from the wall surface, or remove the cement wall surface, and install a layer of gypsum board or “five-centimeter board” outside the insulation layer. , and then do latex paint on top. This method can remove all irregular cracks. The cracks are usually the joints between the boards, which are easier to deal with. However, this method is more expensive and difficult to construct.
4. Use elastic decorative materials. Currently, there is a kind of “elastic putty” that can make up for the problem of wall cracks to a certain extent. Certain types of wall paint can also cover small cracks in the wall. However, these materials themselves are less “elastic” 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 used once and for all, it will reduce the thermal insulation and thermal insulation performance of the wall, so it is not recommended that you use it.
6. The wall of the construction hole in the civil construction is built at the back. If it cannot be naturally connected to the original wall, cracks will occur, so the bricklayer Be sure to stagger the plastering seams, otherwise the painter will not be able to completely solve the problem of cracks even if it is a fitting cloth.
7. After the room decoration is completed, a basin of water can be placed in each room to maintain the humidity of the indoor air, which can effectively prevent wall cracking. If you can figure out what is causing the wall cracks, it would be best to prescribe the right remedy. </p
