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 clean 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
Epoxy wood filler makes an excellent solution to repairing woodwork as it goes on as a paste and can be drilled, chiseled, machined, sanded, and accepts paint and other finishes. Purchase an epoxy wood filler in a shade to match your corner molding.
Knead the epoxy until the color is uniform. The mixed compound can then be applied and pressed into the chips and cracks with a spatula, a putty knife, or even syringes or brushes until it is slightly mounded. Use a putty knife to finally smooth the surface level with the 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.
