Wood putty is meant only for very small imperfections in already stained wood. Putty comes in many shades to match the piece being repaired. It is a better option for furniture and small items that don’t see a lot of wear and tear. Wood filler is more durable than putty and provides a tight bond with the wood. It hardens so it can be treated like wood, accepting nails and other attachment devices. Wood filler is ideal for surfaces that have not been stained or are going to be refinished to provide a perfect match to the other wood surface.
Before applying wood filler to the floor, sand the area surrounding the damage lightly to provide a surface free of stains, oils and other materials. Spray an oil-free cleaner over the wood and wipe with a soft cloth. Once dry, clean the area again with a microfiber cloth to remove any dust left behind.
Apply a generous amount of wood filler to the damaged area of the floor. Press the filler into the hole with a putty knife. Continue to apply filler until the entire area has been filled and there is a slight raised mound of filler over the hole. Swipe the putty knife over the area to remove any excess wood filler from the floor. Allow the wood filler to dry for 2 to 6 hours, depending on the depth of the damaged area. Sand the surface of the wood filler with fine grit sandpaper to make it smooth with the remainder of the floor.
Wipe away sanding dust with cheesecloth or microfiber cloth. Apply a wood stain to the floor to match the existing floor. Feather the stain into the existing stain to create an even match and flow to the color. Allow the stain to dry, and apply a second coat if necessary to achieve the desired color. Protect the floor with a coat of polyurethane after the stain has dried. Keep the floors looking great with a weekly mopping to erase any dirt and shoe marks. Protect the floor from future scratches and imperfections with a monthly coat of wood floor wax.
