Step 1

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.

Step 2

Using a putty knife, apply a thin layer of patching material to the damaged area. Allow it to dry.

To create an even surface, always smooth out (feather) the patching material 1"-2" beyond the repaired area.
Step 3

Use 220-grit sandpaper to smooth the patched area and make it even with the surface.

If shrinking of the patching material occurs, lightly sand and clean the area and apply additional layers of patching material as needed.
Step 4

Remove any final dust or debris from the finished repair.
