First, the cause of wall cracking
1. The settlement of the house is mostly caused by uneven settlement of the foundation, which is common in old-fashioned multi-storey houses. Specifically, the surface of the wall exhibits a 45° direction crack. The top surface is mostly through the ends of the east and west. In addition, if it is old-fashioned as a slab structure, cracks often occur at the junction of two floors. Generally, the cracking conditions are different, and different treatment measures are needed to repair the cracks to prevent cracking of the wall paint in the future.
2. In order to make the wall surface more smooth and fine, the painting effect is better, we need to carry out the operation of batching putty on the wall surface. If cracks appear in the putty layer, it will cause cracks on the surface of the wall. The reason for this may be that the quality of the putty is not up to standard, or the putty is too thick, or the construction operation is not standardized. When the putty is scraped after the scraping, the putty is not completely dried out.
3. The problem of the original wall quality is a major cause of cracking of the wall paint after the decoration. There are two common problems of the original wall: one is the crack of the plaster layer and the hollow drum; the other is the empty layer of the putty layer. Most of the cracks or empty drums in the plastering layer and the putty layer are caused by the developer's poor quality of raw materials, mismatched proportions, and carelessness in construction. Therefore, consumers must carefully check the quality of the wall when collecting the house. Once the problem is found, the decoration must be handled in a targeted manner.
Second, the wall putty cracking solution
1. Usually, the base layer should be completely removed during maintenance, the cracks should be cleaned out, and then filled into the gap with epoxy resin injection until the gap is filled. Fix the carbon fiber anti-cracking cloth on the surface of the gap. After all this is done, you can fix the putty to make the latex paint.
2. 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 caulk and grind it, level it with a mesh cloth or kraft paper, and level it with putty, and paint according to normal procedures. Or you can paste wallpapers.
3. If there is a large area of ​​empty plaster on 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 leveled and then painted according to the normal process. However, after this treatment, the cost will increase relatively. If there is only a small area of ​​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.
The most common problem on the wall of the house is the cracking of the putty. This is the problem that most wall faces will appear.
