If the putty is scraped, it is usually scraped three times. During construction, remember to scrape the putty for the second time, and be sure to dry it. We'd better control the thickness of putty at about 2mm, and it's better not to exceed this requirement. When it's cold, just scrape putty and maintain it. If it is not completely dry, you'd better close the window. This is to prevent the dry wind from blowing the putty dry and cracking. For lamp polishing, straightness and levelness are required in the treatment of yin and yang angles. When scraping putty, if raised sand particles or other sundries are found, they should be handled in time.
The ratio of water to putty powder, the putty scraped for the first time, does not require light but leveling. Generally, the putty used to brush the wall surface is required to be scraped three times, but each scraping is required to be dried and then brushed again. When scraping putty, you must prevent the cool wind from blowing directly, so although it seems that the wall can be dry, it turns out that the water is locked in the wall. If the next operation is carried out at this time, compared with the heating in winter, the wall materials that are not dry begin to transpiration and appear "dry crack".
When the absorption ratio of the bottom layer is strong, it should be sealed with primer when scraping the wall putty. This is to prevent the putty glue from being absorbed too much by the bottom layer, thus affecting the adhesion of putty. Scraping putty should grasp the squint point of the wall, and require uniform force to ensure the fullness of putty.
How to deal with internal wall putty scraping and internal angle straightening
1, wall treatment, the basic requirements are the same as those of the white-gray hemp knife cover. The floating ash on the wall, roof and slab joints shall be cleaned up, and the residual sundries and protruding parts shall be removed.

3. For the wall with fast water absorption, it is best to spray 1: 2 or 1: 3 107 glue solution to prevent gypsum putty powder from losing water too quickly and causing pulverization. Gypsum board wall should be wiped with a wet cloth first, and then covered.
4. Use white mortar, cement mortar and mixed mortar to make the wall surface, and cover it when the bottom layer is dry to 60 ~ 70%. If the bottom layer is too dry, it should be watered and wet. Generally, finishing can be carried out 2 ~ 3 days after bottom ash plastering. Top plastering shall be applied vertically and thinly, then leveled horizontally and calendered. The total thickness of two times should not exceed 2mm. Set the angle of yin and yang with a square ruler, and then press it with a small press.
