How to deal with scraping white If we only want to scrape white on the wall, then we should deal with the grassroots. That is, all grass-roots units should have strength, and those with unqualified strength, such as sanding, hollowing and cracking, should be reprocessed. Remove the original unqualified parts, plaster them again, and then brush the wall firmly. If the smoothness of the wall is good, then putty can be directly approved. If the flatness of the wall is poor, it needs to be leveled with gypsum plaster. After the basic treatment, it will be scraped white, because we will move in after scraping white, so I suggest you scrape water-resistant putty in batches at this time. Because ordinary putty, after scraping, if we live in it, there will be powder on the wall. If our clothes or bodies touch this common putty, it will stick to our bodies and clothes, so we really can't live. So I suggest you use water-resistant putty. After scraping the latex paint with water-resistant putty, the wall will be polluted to some extent after staying for several years. At this time, we are not allowed to brush latex paint directly on the wall. Because pollution pollutants will cause the following problems: first, it is easy to cause latex paint to fall off in the later stage, and second, it is easy to cause the underlying pollutants to stand out; Finally, the latex paint wall you brush will be ugly, with uneven color and various spots. In fact, the treatment of water-resistant putty was very simple before, because we were the first batch of water-resistant putty scraped, so there was no problem in strength after several years of use. However, what we need to do is to polish the original putty wall. We can completely smooth the putty wall with sandpaper, and then blow the surface up and down. In this way, after the original putty is treated, you can brush latex paint. When you brush latex paint, you should follow the standard operation process, that is, you must have one bottom and two sides. This is the most basic practice. No, it can be violated. You can't just brush it once, so the final effect will be poor, there will be color difference, and more seriously, there will be various plaques. Therefore, latex paint should be painted in strict accordance with the requirements and operating procedures. According to this requirement, even after the second renovation, there will be a brand-new and beautiful wedding room.
