Suggested Tools & Supplies
  • 5-in-1 Tool
  • Vinyl Gloves
  • Ladder
  • Patching Material
  • Protective Apparel
  • Putty Knife
  • Rags
  • Sandpaper
  • Step 1

    Using 80 to 100-grit sandpaper, remove any loose debris from the cracked area.

    TIP: Use a 5-in-1 painter's tool to widen cracks that are less than ¼" wide. This will remove the paint and other debris from the cracks and will allow the patching material to bond tightly to the damaged area.

  • Step 2

    Using 100-grit sandpaper, lightly sand any raised or rough areas. Remove any dust or debris from the area with a lightly water-dampened rag.

  • Step 3

    Using a putty knife, spread a thin layer of patching material into the cracked 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 4

    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 5

    Remove any final dust or debris from the finished repair.
