Step-by-Step Instructions
Clean the area
5-10 minutes
Clean the scratched area with wood floor cleaner. Remove all dirt, wax buildup, and debris. Let dry completely. A clean surface is essential for repairs to adhere.
Assess the scratch depth
2 minutes
Run your fingernail across the scratch. Surface scratches (in the finish only) are easier to fix. Deep scratches that penetrate to the wood require more work.
Pro Tip
If you can feel a groove with your nail, it's a deep scratch.
Fix surface scratches
5-10 minutes
For scratches in the finish only: apply a wood floor repair marker that matches your floor color. Work along the scratch, filling it in. Wipe off excess with a clean cloth. Let dry.
Pro Tip
Test the marker color in an inconspicuous spot first.
Fix deeper scratches (wood damage)
10-15 minutes
For deeper scratches: use a color-matched wax stick or wood filler. Press the material into the scratch, overfilling slightly. Use a plastic putty knife to scrape off excess, level with the floor.
Pro Tip
Wax sticks work well for minor gouges. Wood filler is better for larger damage.

5-10 minutes
Once filler is dry (if using wood filler), lightly sand with 220 grit sandpaper to level and smooth. Wipe away dust.
Pro Tip
Sand gently and only the repaired area - you don't want to damage surrounding finish.
Seal the repair
10 minutes plus dry time
Apply a thin coat of polyurethane over the repair using a small brush or applicator. Feather the edges to blend with surrounding finish. Let dry completely.
Pro Tip
Match the sheen of your existing floor (satin, semi-gloss, etc.).
Multiple scratches or large area
1+ days for full project
For many scratches, consider a screen and recoat: lightly sand (screen) the entire floor and apply a fresh coat of finish. This requires more time but gives uniform results.
Pro Tip
This is a bigger project but can transform a scratched floor.
Common Mistakes to Avoid
- Not cleaning the area first (repairs won't adhere)
- Using wrong color filler (very noticeable)
- Over-sanding and damaging surrounding finish
- Not sealing the repair (won't last)
- Using wax products on polyurethane floors (causes adhesion problems)
Safety Warnings
- Ensure good ventilation when using polyurethane
- Keep rags with finish products in water-filled container (fire hazard otherwise)
When to Call a Professional
For deep gouges that go through the veneer, for wide areas of damage, for full floor refinishing, or for engineered floors that can only be sanded once.
