How to Paint Old Dry Windowsills
- 1). Use sandpaper to sand away all of the windowsill's old paint and smooth out the wooden surface.
- 2). Use a sharp object like a screwdriver to dig out any loose, dry wood in the windowsill. Loose, dry wood is too far gone to repair. Remove it so it doesn't affect the aesthetic appeal of your paint job.
- 3). Fill holes or cracks with an epoxy filling. Layer it on with a putty knife. Wipe away any excess epoxy with the knife.
- 4). Sand the epoxy filling when it has dried. The windowsill must have a completely smooth surface.
- 5). Use a damp rag to clean up the windowsill. Any dirt or debris may keep the paint from adhering to the wood properly and create a rough surface.
- 6). Dry off the windowsill with another rag or dry towel.
- 7). Add a layer of primer ti the windowsill with a paint brush. This helps protect the windowsill from the elements.
- 8). Paint the windowsill with your color of choice and a paint brush. Keep strokes even and in the same direction. Allow the paint to dry.
