It’s a good time to decorate in the fall. However, as the temperature turns cold, the rain is less, and the air dryness is increased. In the autumn, various materials are prone to dry cracking, which affects the decoration effect and quality. Therefore, anti-drying is a problem that cannot be ignored in autumn decoration. Wall decoration occupies a very important position in the home decoration. Below the top ten brands of Chinese plate|Yuansenyuan, we share the method of anti-cracking of the wall paint on the autumn wall. The autumn wall is easy to crack and recognize the enemy's situation. The autumn wall is easy to crack. It refers to the dry climate in autumn, which tends to cause the wall material to shrink and cause the wall to crack. It should be noted that it is not that the wall painting in the autumn decoration will definitely have cracking problems, but the cracking problem can also be avoided, but this needs to be from the selection of materials, preparation, construction to maintenance, and every step is to prevent cracking measures. . 1. Cracking of the wall surface The cracking of the wall surface refers to the formation of linear, multi-angle or irregular cracks or cracks on the paint film on the wall surface. Many owners' new homes will be more or less cracked on the wall after a period of renovation, even in a very short period of time. The cracking of the paint film on the wall surface will seriously affect the visual effect of the decoration of the wall surface, and even cause the cracking of the paint film to expand and affect the life of the wall surface. 2. There are many reasons for the cracking of the wall surface caused by the classification of wall surface cracking, but it can be summarized into five aspects. They are cracking of the paint layer, cracking of the putty layer, cracking of the plastering wall, cracking of the joint and structural cracking of the wall itself. First, the cracking of the paint layer: cracks on the wall surface caused by cracking on the wall paint layer, mainly due to the quality of the wall paint product and the improper operation during the construction of the wall paint. Treatment method: If it is only the crack of the surface paint film, grind the crack with fine sandpaper, choose the same wall paint, and repaint it. Second, the putty layer cracking: wall scraping putty can make the wall surface more smooth and delicate, flatness is much higher than the cement wall surface, so that the wall surface paint effect is better, but also save paint. If the putty layer is cracked, it will easily lead to cracking of the surface layer. Therefore, care should be taken to avoid cracking of the putty layer during construction. Treatment method: If the crack has penetrated into the putty layer, first use a sharp tool to enlarge the crack to a size of a screwdriver, fill the caulking gypsum and polish it, level it with a mesh cloth or kraft paper, and level it with putty. Finally, follow the normal process. Paint or paste wallpapers. 3. Plastering of plastering layer: Cracks in plastering wall are divided into normal cracking and abnormal cracking. Normal cracking mainly refers to cracks in the plaster layer caused by shrinkage of cement mortar; abnormal cracking is mainly due to material or construction. Crack caused by improper process. Normal cracking is difficult to avoid, but abnormal cracking can be avoided. Treatment method: If there is a large area of ​​empty plaster in the plastering layer, the original plastering layer should be knocked out, and the plastering layer of the cement mortar should be re-worked, and then the paint should be painted according to the normal process. However, after this treatment, the cost will increase relatively. If there is only a small area cracking, no sanding, empty drums, and falling off, you can stick the wall with a good cloth, and then paint according to the normal process. 4. Cracking at the joint: Cracking at the base of the wall joint will cause cracks on the surface of the wall. The joint cracking mainly occurs at the joint between the reinforced concrete shear wall and the ceramsite brick, the joint between the reinforced concrete beam and the ceramsite brick, the rear gated door, the gypsum board partition and the original wall joint. At the office. The crack at the joint is mainly due to the surrounding environment or external force. The gypsum board, prefabricated partition wall board and prefabricated floor slab will shrink and change position, resulting in cracks at the joint, generally vertical or horizontal. Treatment method: It is recommended to repair the whole building after the deformation tends to be stable, and the repair within a short time is prone to repeated. 5. The structural layer of the wall itself is cracked: the cracking of the structural layer of the wall itself may also cause cracks on the surface of the wall. Including two cases, first, the original wall surface itself has cracks, and no appropriate treatment measures were taken during the later decoration process; second, the original wall surface was not cracked in the decoration fashion, and the ground settlement was uneven and temperature change in the later stage. Cracks occur for a large number of reasons. Treatment method: The ordinary decoration method cannot be repaired. It is necessary to find professional building structure personnel to take corresponding measures according to the actual situation. The above several types of cracking may cause cracks in the final wall paint wall surface, and the degree of complexity and damage gradually increase in the above order. With this knowledge in mind, we can take steps to mitigate or even avoid wall cracking. The table lists the methods for judging the causes of cracks on the surface of the wall. You can find out the cause of the cracking of the wall and use the right medicine. Http:// http:// http://
