Clean the wall
Before you start to remove putty, you need to clean the wall to make sure there is no dust and debris on it. You can clean the wall with clean water or detergent, and then dry it with a clean cloth.
Grind the wall
Sand the wall surface with sandpaper to remove the old putty and protruding parts of the wall surface. It can be polished with 200-400 sandpaper until the wall becomes smooth and flat.
Scrape off the putty
Scrape off the old putty with a putty knife or putty spatula. Be careful not to scratch the wall when scraping, and the direction of scraping should be consistent with the wall. If the putty is difficult to scrape off, you can soak it in water for a while before scraping.
Grind the wall
After scraping off the putty, it is necessary to polish the wall again with sandpaper to remove the residual putty and protruding parts. It can be sanded with 600-800 sandpaper until the wall becomes smooth and flat.

These are the steps to quickly remove putty from old walls.
It should be noted that care should be taken in the process of removing putty to avoid scratching the wall or damaging other items. At the same time, we should also pay attention to safety and wear protective equipment when decorating.
