1. Prepare tools: prepare a scraper or scraper with appropriate size, and select the appropriate tools according to the wall area. At the same time, make sure that the blade of the tool is sharp, so as to scrape off the paint better.
2. Protect the surroundings: Before scraping, cover the surrounding floor, furniture or other decorations with plastic film or cloth to prevent the scraped paint from being polluted or damaged.
3. Wet treatment: Before scraping, you can wet the paint surface to be scraped with a wet cloth. This will soften the paint and make it easier to scrape off.
4. Paint scraping: Put the scraper or scraper on the wall, and scrape the paint evenly and forcefully at an appropriate angle. One-way or cross scraping can be used until the white on the wall is completely scraped off. Pay attention to avoid overexertion, so as not to scratch the wall.
5. Cleaning: After scraping the paint, clean the paint and dust left on the wall with a cleaning cloth or vacuum cleaner. Ensure that the wall is clean and tidy, which is convenient for subsequent decoration work.
Please note that scraping white is a time-consuming and laborious work, which needs to be handled carefully to avoid damaging the wall. If you are not familiar with scraping or are not sure about the operation method, it is recommended to consult professional decoration workers or paint suppliers for more accurate guidance.
