1. What are the methods of punching holes in the wall?
1. When drilling, you can choose electric drill, pick, electric hammer, etc. They all need the cooperation of suitable drill bits to complete the drilling task.
2. When drilling, be sure to keep it perpendicular to the drilling surface, hold the electric drill tightly with both hands to ensure the stability of the electric drill, draw the drilling position with a pencil, and select the appropriate expansion screw.
3. The expansion screw is too small and falls directly into the hole, so it can't be fixed.
4. Drive the expansion screw into the drilling hole with a hammer, pay attention to protect the thread of the expansion screw, and finally complete the drilling.
5, special wall punching: sometimes the location of punching is a bit special, for example, punching holes in beams is used to penetrate things, and sometimes it is necessary to cut the wall. These wall holes need professional consultation.
Second, what are the steps of wall painting?
1, wall quality inspection
Before plastering the wall surface, it is necessary to conduct a comprehensive inspection of the wall surface quality, observe whether the wall surface quality is qualified, and whether there is any phenomenon such as falling off and cracking, so as to ensure that the painted wall surface is smooth and solid. If there are big cracks and holes in the wall, the owner can ask the developer or the property to redo it. If there are only a few holes, the owner can fill them with plaster.
2. Wall treatment before putty scraping
When you confirm that the wall surface is smooth and firm, then we can use steel brush or professional tools to remove impurities from the wall surface and ensure that the cement wall surface is as free from floating soil and slurry as possible. Then we will roll the concrete interface agent to the wall as evenly as possible and leave it for about 2 hours. When it's completely dry, we can start scraping putty. Brush a layer of interface agent before scraping putty, which can prevent putty from loosening, floating soil or being too dry due to cement wall.
3, blow be bored with child
In this process, we should master the correct construction method. Generally speaking, the wall should be scraped with putty twice, which can make the wall smooth and cover the background color. If it is putty with poor flatness, we need to scrape it several times in some areas. If the wall with poor flatness is seriously inclined, consider scraping gypsum for leveling first, and then scraping putty. At the same time, it should be noted that the interval between each batch of putty scraping should be more than 2 hours.
4. Pigment
After the putty construction is completed, we will paint it again. At this time, it is necessary to follow the principle of priming first and then painting, so as to ensure the good decoration of the wall, and the top coat is the final effect of the wall.
The above is about the method of wall punching and the steps of wall painting. I hope I can give you some reference. Be careful when decorating, and don't hit the load-bearing wall when punching holes.
