The latest method of whitewashing (there are several methods of whitewashing)

1. Wall quality inspection: Before painting the wall, first check the wall quality. If there are big cracks or holes in the wall, it is best to ask the developer to redo it. If there are some small holes, they can be filled with plaster.

2. Wall treatment before putty scraping: Before putty scraping, the wall must be cleaned to ensure that there is no dust and impurities on the wall, and then the concrete interface agent is rolled on the wall to avoid the wall being loose and dry when putty powder is brushed again. After the interface agent is dried, putty can be scraped.

3. Blow putty: Before blowing putty on the wall, it is necessary to measure the flatness of the wall with a measuring ruler to determine which method to blow putty. Usually, the wall can be scraped with putty on both sides, which can not only level, but also cover the background color. If the smoothness of putty is too poor, it needs to be scraped several times. It should be noted that the water-resistant putty should not be scraped too thick, otherwise it will crack easily when it is dry.

4. Painting: After scraping the putty on the wall, you can start painting the wall. Paint needs to be primed, mainly for those walls that don't need special treatment. If there is a problem with the wall, choose a special primer for this problem. After the primer is applied, the top coat is applied, and the wall painting is completed after the top coat is applied.
