“Wall†is something that everyone, every day, will see. If the wall is not doing well, it will not only affect the overall environment of the home, but will also make the residents feel bad.
Strictly speaking, the renovation of the wall has already included "decoration" and "decoration". The grassroots treatment can be counted as a "decoration" (basic nature, long-term benefit of a construction), paint, wallpaper, etc. Counted as "decoration" (decorative, regular replacement).
"Rubber Room Brush Latex Paint" is a typical case. I divided the construction process into eight steps, hoping to help us master some principles and essentials.
Step a big check.
Case 1: Cement wall. 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. If the wall surface roughness is poor (error greater than plus or minus 5mm), you should consider to do plaster leveling.
Situation 2: putty wall. Be sure to check whether the wall putty is a qualified waterproof putty. If not, you must shovel off the red water-repellent putty. The other items in the same situation are the same.
Step two 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 Prepare the scraper/gypsum. 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 roller (individual walls may need to be patched), as far as possible, wait until it is dry (usually more than 2 hours), you can scrape putty / plaster.
Step 4 Putty (please choose water 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 scraping of the wall can be done 2 times. It can both level and cover the background. Poor flatness requires a few more scrapes in the area. If the flatness is extremely poor or the wall is tilted, consider leveling the gypsum first to level it, and then scrape it. The scraping time should be more than 2 hours (after surface drying).
Step five polish 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 light bulb of more than 200 watts to illuminate the wall (evening during the day needs to be levelled with a light bulb), and check the flatness while grinding.
Step six 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 seven 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 eight 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.
Although the above is just a case of various wall decorations, it is very representative. Various other wall decorations can be evolved from these steps. Examples are as follows:
The old wall was refurbished , but the steps were slightly different. A few changes can be as follows:
Refurbishment of the old wall Step 1: Check the strength of the existing wall. If it is solid, directly remove the paint film from the surface layer, and step 2 can be skipped into step 6; if it is not solid, all the existing wall skins will be shoveled out and the process will proceed to step 2.
For the wallpaper , the first five steps are the same (decoration section), starting from step 6 and changing to the brush base film, etc., which will not be described here.
