Many friends will encounter such a problem after the renovation: wall cracks ! Cracks in the wall of new houses are a common problem, but what should we do in the face of this problem? Renovation home decoration network Xiaobian suggestion: find the reason to do the key, it is more convenient to handle!
1. a crack in the crack of the gap between the wall insulation board and the board;
2. The wall is slotted, and the shrinkage crack occurs in the wire groove ash;
3. Plastering putty uneven stress cracks appear.
1. If there is insulation board on the wall, remove the insulation board on the wall surface, or remove the cement wall surface. Install a layer of gypsum board or “five PCT board†on the outside of the insulation layer, and then make latex paint on it. This method can remove all the irregular cracks, and the cracks are generally the joints between the plates, which is better to handle.
2, the wall cracks mainly bring the problem of rain and rain, but when it is really leaking, it is very difficult to completely decorate the wall surface, so it is necessary to do a good job of defense. The water-repellent powder is a light dry powder, which can be easily lost by wind and rain. Therefore, the protective layer must be made of reinforced concrete to prevent its outflow for a long time.
3. The reason for the crack after the ash filling is that the drying speed and shrinkage rate of the cement mortar are different from the putty powder. After the putty on the surface of the wall has dried out, the cement mortar inside has not dried up, so cracks appear. Therefore, the effect of using gypsum powder in the line groove is better.
4. If the wall putty is too thick at a time, or the thickness of the entire wall is too wide, cracks may occur. Serious will also fall off. If necessary, you should scrape it a few more times. Each time it is thinner, the interval should be longer. But pay attention to the number of putty putty, and it is easy to fall off.
The above is the knowledge about the wall cracks introduced by the decoration house Xiaobian. The different wall cracks are treated differently, so the prevention of wall surface treatment is the most important. For more related knowledge, please pay attention to our decoration encyclopedia!
