For large scratches or chips in your hardwood flooring, you are likely to need a sustainable wood filler, a stain pen, or stain matching your floor. You can use a small painters tool or putty knife and a sanding sponge or sandpaper. The first step is to apply some painters tape around the scratched area and then add the wood filler into the scratch while taking care to keep the surface as smooth as possible. Once dry you will want to lightly sand the area and attempt to feather the edges with the surrounding floor to blend it in. Next, apply stain to the repaired area. It’s always a great idea to test the look of the stain on the wood filler in an inconspicuous area or on a piece of scrap wood to make sure the stain turns out well on the wood filler.
These are just a few ideas on the ways that you could fix a scratch on a hardwood floor. For heavier damage, you will want to replace or refinish the damaged area. However, this can be time consuming and expensive, so if you can use one of the methods above for smaller scratches, you can definitely increase the life and usefulness of your hardwood floor.
