How to repair scratches on wooden floors

Scratches on wooden floors are bound to appear over time, even with careful upkeep. The majority of scratches are caused by moving furniture, pet paw prints, and small sand particles that make their way inside the house. Restoring the appearance of a wooden floor can be relatively easy, depending on the severity of the scratches. With just a few simple steps, you can repair and cover up scratches to keep your wooden floors looking beautiful and durable.

Clean the scratched area. Use a soft cloth dampened with water to gently wipe off dirt and debris from the surface of the wooden floor. Ensure there is no dust or sand on the scratched area before proceeding.

Test the color first. Before using a scratch repair pen on wood, it’s recommended to test it in an inconspicuous area of the floor to see if the color matches. If the color of the pen is close to the wood’s original shade, you can proceed with using it to repair the scratch.

• This type of pen comes in various colors and can be found in supermarkets, household goods stores, and paint shops.

Use the scratch repair pen to cover the scratched area. Once you’re sure the pen matches the wood color, you can apply it to the scratched surface several times. Don’t worry if the newly applied color looks slightly lighter than the wood tone. You can touch it up after wiping off any excess color.

Rub the area to let the color soak into the scratch. Use a clean cloth soaked in white gasoline to rub the wood floor, focusing on the scratched area. Rub over the colored area to clean off excess color, making sure to follow the wood grain.

• This method is the most effective (more so than using the pen directly on the scratch), as the color gradually soaks into the scratch little by little.
• If you use the scratch repair pen directly on the scratch, the scratch may become saturated with color, and eventually, it will appear darker than the surrounding wood. This method may make the scratch even more noticeable.

Clean the scratched area. If the protective coating of the wooden surface is scratched, use a soft cloth (such as a microfiber cloth) and a little wood floor cleaner to clean the scratched area.

• Make sure to remove any dust particles to prevent them from sticking to the floor when applying the covering product.

Clean the floor cleaner solution. The next step is to dampen another cloth with water and wipe the area again to remove the floor cleaner solution.

• Allow the floor to dry before proceeding to the next step.

Apply a surface coating. Once the scratched area is completely dry, use a fine-tipped brush to apply a thin protective coating over the scratched floor. This coating could be a sealant, polyurethane, or resin. Ideally, the material should match the existing finish of the floor.

• Ask staff at the home improvement store for recommendations on the best material for your wood floor.
• If you're inexperienced or if your floor has been treated specially (e.g., a glossy PU finish), consider hiring a professional service for the repair and refinishing.
• Hiring professionals can be more costly, so it may be best to wait until there are multiple scratches before calling them, rather than for a single minor scratch.

Clean the scratched surface. Use a soft cloth and some floor cleaner to wipe the scratched area. This step will help remove dust and ensure the surface is clean for further treatment.

Wipe the scratched area again. Use a dampened cloth to wipe the scratched surface once more. This will help remove any remaining floor cleaner and ensure the surface is thoroughly cleaned.

• Wait for the floor to dry completely.

Fill the scratch. Use a wood polishing wax stick to rub over the scratched area to fill in the scratch. If necessary, you should use a putty knife to smooth the wax into the scratch. The wood polish wax may be colorless or available in common wood shades like honey and brown with various hues. Wait at least 10 minutes for the wax to dry and harden.

• You can find wood polish wax sticks at supermarkets, paint stores, or building material shops.

Let the wax bond and dry. Wait one or two days before polishing or applying an additional finish layer to the wooden surface.

Polish the scratch. Use a soft, clean cloth to rub the scratched area and polish the wax. The polishing step will smooth the scratched surface, remove excess wax, and restore the floor’s shine.

Clean the scratched surface. Use a soft cloth dampened with floor cleaner to clean the scratched area.

Clean the floor cleaner solution. Dampen a clean cloth with water and wipe it over the scratched area on the floor. This step ensures that the surface you're working on is free of dirt and debris.

• Allow the scratched area to completely dry before proceeding to the next step.

Rub mineral spirits on the scratch. If the wood surface is coated with a PU finish, you’ll need to remove the coating before addressing the scratch. If there is no finish layer, you don't need to worry about removing the surface coating. Moisten a cleaning pad with mineral spirits and gently rub it over the scratched area. Use a clean cloth to wipe off any excess and let it dry completely.

• If you lack experience working with wood and fillers, it’s recommended to hire a professional service for the job.

Fill the scratch. Use your index finger to apply a small amount of wood filler that matches the floor color, then fill the crack or scratch. Smooth the filler in all directions to remove air bubbles. You may need to apply more filler, as excess will be cleaned off later.

• Ensure you use wood filler instead of wood putty. These materials are different, and using wood putty can affect the blending with the wood, leading to a mismatch in color.
• Wait for the filler to dry for a day.

Remove excess filler. Once the filler has dried, use a putty knife to smooth the surface and press the filler into the scratch. Smooth in all directions to ensure the edges of the filled area are even and smooth.

Sand the excess filler around the scratch. Use fine sandpaper (around 220 to 300 grit) and gently sand the wood surface around the scratch, especially where the filler remains.

• You can sand along the wood grain or make small circular motions. Regardless of your method, remember to be gentle.

Wipe off excess filler. Dampen a cloth with water and wring it out completely. The cloth should be slightly damp, not wet. Use your finger to carefully wipe around the scratched area.

• Remember to only clean around the scratch, where the filler has spilled over, and avoid wiping over the filled scratch itself.

Apply a finish coat to the patched area. Brush a thin layer of the same material that was previously used on the floor over the repaired area. Use a natural bristle brush or a lambswool roller to apply PU, varnish, or other finishes. Allow the coating to dry completely for about 24 hours before walking on the floor.

• If you use a foam roller, it may cause air bubbles to form on the finish.
• It may be necessary to apply at least two coats for the best results.
