If the flatness is very poor, the wall is severely tilted, you can consider scraping the plaster first for leveling, and then scraping the putty. The interval between each batch of putty scraping should be more than 2 hours (after the surface is dry).

Sanding putty. After 1-2 days of water-resistant putty, the putty will be sanded. Sanding can be done at night, with a light bulb of more than 100 watts close to the wall, and check the flatness while sanding.

Brush the topcoat. The topcoat is usually brushed twice, and each time should be separated by more than 2-4 hours (depending on its surface drying time) to allow it to be basically dry. After the second coat of topcoat brushing, it takes 1-2 days to completely dry, and before the paint is completely dry, attention should be paid to waterproof, drought-proof, and sunscreen to prevent problems with the paint film.
