How To Fix Deep Scratches In Wood Floor

If you have a wooden floor, it is inevitable that it will get scratched over time. And while some scratches can be easily fixed with a touch-up pen or wax stick, deep scratches require a little more effort. In this article, we will guide you through the process of fixing deep scratches in wood floor.

What You Will Need

Before you begin, gather the following materials:

  • Sanding paper
  • Wood filler
  • Putty knife
  • Polyurethane sealant
  • Paintbrush
  • Clean cloth

Step 1: Sand the Scratched Area

The first step is to sand the scratched area to remove any loose wood fibers and smooth out the surface. Use sandpaper with a fine grit, and sand in the direction of the grain. Be careful not to sand too much, as this can create an uneven surface.

Step 2: Fill the Scratches

Next, use a putty knife to apply wood filler to the scratched area. Make sure the filler is level with the surrounding wood surface. Allow the filler to dry completely before sanding again.

Step 3: Sand Again

Once the filler has dried, sand the area again with a fine grit sandpaper until it is smooth and level with the surrounding wood surface.

Step 4: Apply Sealant

Apply a coat of polyurethane sealant to the repaired area using a paintbrush. This will protect the wood and give it a glossy finish. Allow the sealant to dry completely before walking on the floor.


Q: Can I use wood stain to cover up the scratches?

A: Wood stain is not recommended for covering up deep scratches, as it will not fill in the gaps and may make the scratches more noticeable.

Q: Can I use wood filler for large scratches?

A: Yes, wood filler can be used for large scratches, but it may take longer to dry and require more sanding.

Q: How long should I wait before walking on the repaired area?

A: You should wait at least 24 hours before walking on the repaired area to allow the sealant to dry completely.


Fixing deep scratches in wood floor may seem daunting, but with the right materials and techniques, it can be done easily. Remember to sand the area, fill the scratches with wood filler, sand again, and apply a coat of polyurethane sealant. With these steps, your wood floor will look as good as new.
