How to brush the wall
Step one: big inspection. Check thoroughly whether the cement wall surface that needs to be painted in the rough house is firm and flat. If the plastering layer of the wall is not strong enough or there are large cracks and holes, it is recommended to complain to the developer or property and ask them to redo. Individual holes are repaired by themselves and can be filled with plaster.
Step 2: Finished product protection. There will be dust when handling the walls, and there will inevitably be putty, paint or other glue dripping, so be sure to do a good job in the protection of the finished decoration of the room in advance.
Step 3: Preparation before scraping putty. Make sure the wall is solid and flat. Use a steel brush or other tool to clean the wall so that the cement wall is free of floating soil and floating. Roll over the concrete interface agent on the wall and try to make it uniform. When it is dry (usually more than 2 hours), it can be putty.
Step 4: Putty (please choose water-resistant putty). The smoothness of the wall surface should be measured before the putty is used (using a measuring rule of 2 m or more) to determine the method for scraping the putty. The general wall scrape 2 putty can, can both level, but also cover the background. Poor flatness requires a few more scrapes in the area. If the flatness is extremely poor and the wall is steeply sloping, consider scraping the plaster first to level it, and then scrape it. The scraping time should be more than 2 hours (after surface drying).
Step 5: Polish the putty. After the water-resistant putty is completely on strength (5-7 days), it becomes extremely solid, and it becomes extremely difficult to perform sanding again. Therefore, it is recommended to start putty grinding 1-2 days after scraping the putty. Polishing Optional At night, use an electric bulb of 200 watts or more close to the wall lighting, while grinding to see the flatness.
Step 6: Brush primer. After cleaning the floating dust on the polished putty surface, you can apply the primer. The primer can be painted once and it must be even. After it has dried (2-4 hours), the next step can be performed.
Step 7: Brush finish. The top coat usually has to be brushed twice, and each pass should be separated by more than 2-4 hours (depending on the dry time of the watch) until it is substantially dry. After the second round of paint brushing, it takes 1-2 days to completely dry. Before the paint is completely dry, it should be waterproof, drought-proof, and sunscreen to prevent the paint film from having problems.
Step 8: Acceptance. The survival wall should be solid, smooth, vertical and horizontal, no cracks, no holes, uniform color, full paint film, but also pay attention to check the protection of finished products.
