A knowledgeable friend talks about brushing glue on the wall before scraping putty? What effect will it have?

Then you have to adjust the paint color at the paint shop first, and then go home to brush it. Don't help yourself. After all, you have no experience.

1, inspection: comprehensively check whether the cement wall to be painted in the blank room is solid and flat. If the plastering layer on the wall is not firm enough or there are big cracks and holes, it is suggested to complain to the developer or property and ask them to redo it. If individual holes are repaired by themselves, they can be filled with gypsum.

2. Finished product protection: There will be dust when the wall surface is treated, and it is inevitable that putty, paint or other glue will drip. It is necessary to do a good job of finished product protection in the room in advance.

3. Preparation before putty scraping: Ensure that the wall surface is solid and flat, and clean the wall surface with a steel brush or other tools to make the cement wall surface as free of floating soil as possible. Roll the concrete interface agent evenly on the wall as far as possible, and after it is dried (generally more than 2 hours), you can blow putty.

4. Before blowing putty, measure the flatness of the wall (with a measuring ruler of more than 2m) to determine the method of blowing putty. Generally, putty can be scraped on both sides of the wall, which can both level and cover the background color. Putty with poor flatness needs to be scraped several times locally. If the flatness is extremely poor and the wall is seriously inclined, you can consider scraping gypsum for leveling first, and then scraping putty. The interval between each batch scraping of putty should be more than 2 hours (after the surface is dry).

5. Polish putty: Polish putty 0-2 days after scraping putty 1. Polishing can be carried out at night. Bulbs with a power of more than 200W are close to the wall. Check the flatness while polishing.
