2. Grassroots repair.

After cleaning, we all need to fill the uneven parts with gypsum putty and compact, and we need to scrape them horizontally and vertically. The ratio of gypsum putty is: emulsion:

Cellulose aqueous solution 100:5 6:60.

Brush caustic soda aqueous solution: use 5% concentration of caustic soda solution, brush 2 times, if you use 10% concentration, brush once.

15～20。Scraping putty: It is necessary to use a steel scraper for construction, and the scraper should be kept clean, and no floating putty can appear, so as to avoid sand and other debris and affect the construction quality.
