Using a scraper, wire brush, or 80 to 100-grit sandpaper, remove any loose or peeling paint from the damaged area. Remove any dust or debris from the area with a lightly water-dampened rag. Using a putty knife, apply a thin layer of patching material to the damaged area. Allow it to dry.
Use a scraper with rounded corners so you are less likely to gouge the wall and try not to push too hard on the scraper. Some people suggest using a hairdryer or heat gun to loosen peeling paint, but that is generally not a safe option. You could burn down your house.
