Suggested Tools & Supplies
  • Vinyl Gloves
  • Ladder
  • Patching Material
  • Protective Apparel
  • Putty Knife
  • Rags
  • Sandpaper
  • Scraper
  • Wire Brush
  • 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.

    TIP: 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.

    TIP: 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.
