During the process of applying putty, there are the following points to note

1. Choose the appropriate putty that has good adhesion to the primer, good alkali resistance and mechanical strength, as well as good construction performance, including good scraping and filling properties, suitable dryness, minimal shrinkage, and resistance to polishing.

2. In floor coating, when preparing putty, directly add a certain proportion of fillers such as calcium carbonate, quartz powder, etc. to the primer and mix well. When dry, it must be completely dried. Two component putty should be prepared as needed and mixed evenly.

3. The procedure for scraping putty is: the primer is actually dried → scraping putty with a scraper → drying → scraping the second putty → polishing → removing dust → scraping the third putty.
