How to Repair Wood Trim and Baseboard Dings

Baseboards take a beating. Between vacuum cleaner collisions, moving furniture, and the general traffic of daily life, wood trim inevitably collects dents, dings, and gouges. Left untreated, these breaks in the finish draw the eye and can even lead to moisture absorption in raw wood. Repairing trim is one of the most rewarding small tasks you can take on because the transformation is instantaneous. When done well, the transition between the filler and the wood is invisible to the touch and the eye. It is about patience during the drying phase and precision during the final sanding.

1. Clear the damaged area. Use a damp cloth to wipe away dust and debris from the dent. Inspect the damage to ensure there are no loose wood splinters that need to be trimmed away with a sharp utility knife.
2. Fill the dent completely. Scoop a small amount of wood filler onto a putty knife. Press the filler firmly into the dent, slightly overfilling it to account for shrinkage as it dries.
3. Scrape off the excess. Use the edge of your putty knife to scrape away the excess filler, creating a flat surface. Do not obsess over perfection yet; the final profile is achieved through sanding.
4. Sand until flush. Once the filler is fully dry, wrap a fine-grit sanding sponge around the trim profile. Lightly sand the patch until it is perfectly flush with the surrounding surface.
5. Prime the repair. If you are painting the trim, apply a small dab of primer to the filled area. This prevents the filler from soaking up the topcoat, which would leave a dull, noticeable spot.
6. Blend the final finish. Apply a thin layer of matching paint or stain over the repair. Feather the edges outward to blend the new finish into the old one.
