The steps to put the putty are introduced:
Different wall bases have different construction requirements when performing basic treatment.
For cast-in-place concrete walls, because the wall often has some pores and bulging, it is necessary to repair the wall surface, the bulge should be smoothed, and the depression should be filled.
For precast concrete slabs, there are often some gravel, concrete, etc. on the surface. Therefore, professional construction workers need to brush the entire wall with a wire brush to remove these debris.
For cement mortar paper ash surface layer, the wall surface is required to be dry, solid, clean and free of oil.
Step 2: Repairing the base layer of the wall
After the treatment of the base layer of the wall, there will still be some large wall depressions. Therefore, it is necessary to use gypsum putty to initially fill the depressions. When the gypsum putty is prepared, the weight ratio of the gypsum, the emulsion and the aqueous cellulose solution (concentration is 5) is about 100:5:60, and the gypsum putty is compacted by the steel scraper on the wall depression, and the batch is erected horizontally. Scrape again to ensure that the wall is flat.
Step 3: Brushing the aqueous alkali solution
The main purpose of the brushing aqueous solution is to clean the oil on the concrete wall. When painting, it needs to be brushed while cleaning with water. If you are using a 5% aqueous solution of caustic soda, you need to apply it twice. If you are applying a 10% solution, you can apply it once.
Step 4: Brush the binder
Before the official putty putty, it is also necessary to spray the adhesive once, and the ratio of the weight of the water to the binder is about 100:15.
Step 5: Scratch the white putty
When the putty is formulated, the weight ratio of the white powder, the talc powder, the aqueous cellulose solution (concentration of 5), and the emulsion is generally about 60:40:75:3. When scraping putty, it is necessary to use the steel scraper to scrape the wrong plate on the upper and lower sides. It is necessary to avoid leaving the floating putty on the wall and scratches on the wall. At the same time, pay attention to prevent the putty from being dusty, gravel and other debris. .
After the first time the putty batch is scraped, it is necessary to check whether the previously repaired position is still in question. If there is no problem, after the putty is dry, it is necessary to polish the whole wall with fine sandpaper. After polishing, clean the wall. If there are still depressions in these places on the wall, then it is necessary to repair the leveling work again with putty.
Step 7: Finishing the putty
The putty of the putty generally needs to be carried out two to three times. After the putty, the putty must be waited until the last time the putty is completely dried before the construction operation. After the putty is scraped, the whole wall surface is required to be smooth and smooth, the texture is uniform, and the surface is free from scratches. Otherwise, when the latex paint is applied later, the overall decoration effect will be seriously affected.
The steps to put out the putty are here, and it's all over. I don't know if you have seen the process of making putty after reading the decoration of the decoration house.
