  1. 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.

  2. Step 2

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

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

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

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

    Remove any final dust or debris from the finished repair.
