How should the wall be scraped and how much should it be scraped?
You can sprinkle water on the wall first. If the putty falls off with a light scrape, it means ordinary putty. On the contrary, if it cannot be scraped, it means water-resistant putty. Water-resistant putty is firm and solid, so there is no need to scrape it on a large scale. If there is bulging and hollowing, refuse to scrape it. Compared with water-resistant putty, ordinary putty is not as firm and solid. You should scrape directly to the scraping place of the plaster to observe whether the bottom plaster is firm. If you find that the plaster layer is hollow, scattered, and loose, you should continue to scrape until the wall base.
