Corner molding is intended to provide a finished edge to paneled walls and to protect the edges of your walls from bumps and scrapes. Corner molding usually takes the brunt of any damage, often acquiring scratches and chips. If your corner molding has chips, you don't have to replace it, you can patch it to look almost new. Follow these steps to repair corner molding.
Step 1 - Prepare the Surface
Use a small piece of sandpaper to clear the chipped area of loose wood and splinters. There's no need to go too deep, just enough to smooth the area to ensure good adhesion of the wood filler.
Step 2 - Apply Wood Filler
Purchase an epoxy wood filler in a shade to match your corner molding. Knead the epoxy until the color is uniform. Use your fingers to press it into the chip until it is slightly mounded. Use a putty knife to smooth the surface level with surrounding area.
Step 3 - Finish Up
Let epoxy wood fill dry completely, then sand it until smooth. Test with your fingertip to make sure the patch is smooth and level with the surrounding area.
Step 4 - Shine the Surface
Apply liquid wax to the patched area to restore shine and your corner molding will look almost as good as new.
