Our wall repair paste contains silica and methyl cellulose. It can reduce the usage cost. It can respond quickly to emergency repair needs. The usage method is very simple: Please use a scraper to clean the peeling parts of the wall surface to ensure that the surface is clean and dry. Use the scraper to apply the wall repair glue evenly on the damaged area. If the thickness exceeds 2 millimeters， it is necessary to scrape in batches. After the wall repair glue dries (for no less than 2 hours)， use sandpaper to polish the surface and remove the dust. Use a roller or brush to apply the wall paint evenly， and after 2 hours， perform another application operation to complete the repair work. Moreover， once it is applied， it becomes flat and the surface is smooth and fine.
