Tools & supplies

  • 5-in-1 Tool
  • Vinyl Gloves
  • Ladder
  • Patching Material
  • Protective Apparel
  • Putty Knife
  • Rags
  • Sandpaper (100, 220 Grit)
  • Scraper
  • Ceiling/Wall Patch

Step-by-step process

Step 1

Using 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 old caulking, paint, and other debris from the cracks and will allow the patching material to bond tightly to the damaged area.

Step 2

Again using 100-grit sandpaper, lightly sand any raised or rough areas. Remove any dust or debris from the area with a 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.

Tip:

If retexturing of the surface is necessary, choose a finish that will match the existing surface. Textured ceiling/wall patch kits are available in aerosol and powder forms. Follow the manufacturer's recommendations for application.
