Wall drums can seriously affect the beauty of your home. There are different fixes for different causes of wall cavities, otherwise painting won't work.
Two,What is the impact of wall drums on the decorationWe know, then wall drums how to solve?
1. Treatment of cement before the substrate layer of unclean: said wall is fly ash, floating grounding, or even oil or the like, or water is not pre-wetted, making the surface layer of putty lose water too quickly, the grassroots level and the paste layer is not adhered to. Drive to
Repair/Solution: Before applying putty powder, check if there is any ash or oil on the wall. If so, clean it on time. And before spraying putty powder, water is pre-moistened (after the surface is dry, then putty) to prevent moisture loss putty too quickly. Of course, the first step to avoid problems is to choose qualified putty materials and apply them in the right way.
2. The method of structural basic layer or the quality of the raw materials of the plaster layer does not meet the requirements: if the mortar is not uniformly mixed, the sand is too fine, the sludge content is large, then the ratio of cement sand and water is incorrect, and the disposable gypsum is too thick, then the results of the cement stability and so on can not be satisfied in the low-resistance mortar plastering, i.e., the bottom wall is easy to remove the dust. From the point of view of the mass of data often they overlook problems such as low resistance mortar plastering and easy removal of dust. It cannot be easily detected by the naked eye without personal evidence. If you do not fix it in time, it will be placed directly on the putty. After use, it will be air-blown.
Repair: with loose structure, low resistance and easy to remove dust from the wall delaminating putty powder after scraping or setting for brick wall. Then, before using putty, check whether the wall is easy to remove dust? Is the resistance of the sand too low? (Draw with a twig, if you can easily draw grooves, it means that the resistance of the sand is not enough). If so, spray sand removal wall repair sand to repair the wall first, with low resistance and easy removal of dust. The problem is that you can follow the normal procedure to build post-craft putty or wall tiles.
3. Sand wall surface is too soft. Wall surface is too smooth, reduce dust adhesion mortar mastic and putty layer can not form a normal uniform structure with the wall, thus making the layering of empty cylinder. Powder cement and wall need some friction, which means that the rough surface of the wall is more favorable to the combination of powder filler and wall. In actual renovation, such walls are usually too strong and have too smooth a surface (smoothness and flatness are two concepts, so be careful to distinguish between them). Why is the resistance of mortar-plastered walls too high, which can lead to problems, such as empty four walls? I will analyze it in a future article, so stay tuned.
Fix/Solution: big data suggests that the probability of this type of wall having an actual renovation is very low. If there is a problem of this type, the surface of the wall is usually brushed with a sander wall and coarse sandpaper. Then, other processes are usually constructed.
That's it for today's content on What are the effects of wall cavities on remodeling. What is the impact of wall drums on the decoration of your heart must have a number.
