Steps

1
Thoroughly clean the affected area of the hardwood floor to remove all dust, dirt, and debris using a vacuum with a hardwood brush attachment or a soft-bristled broom.
2
For deep gouges, apply a generous amount of color-matched wood filler or pre-colored latex filler into the scratch using your finger, ensuring no air bubbles are trapped and the filler is slightly above the floor level.

3
Use a putty knife or scraper to gently scrape off the excess filler. Press down lightly to avoid creating new scratches on the surrounding hardwood floor.

4
Allow the filler to dry completely. Once dry, use 180-grit sandpaper to lightly rub the area in a circular motion until the surface is smooth and flush with the rest of the floor.

5
Wipe the sanded area with a barely damp cloth to remove remaining dust. Ensure you do not over-wet the area to avoid reactivating the filler.
6
Apply wood stain to the repaired area using an applicator to match the surrounding wood color. Rub off any excess stain with a rag and allow it to dry completely.
7
Apply a thin, even coat of polyurethane sealer over the repair using a high-density foam roller or brush to protect the finish.
8
If the sealer requires it, lightly sand the area with 320-grit abrasive once dry, clean the dust, and apply a final coat of polyurethane for a glassy finish.
9
Allow the floor to dry for at least 24 hours before walking on it. If the damage was widespread or structural, call a hardwood floor professional to sand and refinish the entire floor.

Pro Tips

  • For very superficial scratches, you can rub a walnut meat vigorously over the scratch and buff with a soft cloth to hide the mark with natural oils.
