To finish a hardwood floor, remove the old finish, fill in gouges and choose a finish. Apply the sealer, buff the floor, and add the finish. You need a floor sander, an edge sander, sandpaper and wood putty. Obtain a putty knife, sealer, steel wool, a vacuum and a finish.
- Remove the old finish
Sand the floor in order to remove the old finish. Use a walk-behind floor sander for the bulk of the floor, then sand the edges with the edge sander.
- Fill in the gouges
Use wood putty and a putty knife to fill in any gouges or nicks. Wait for the putty to dry before sanding those particular areas again.
- Clean the floor
Vacuum and wipe up any dust from the sanding.
- Choose a finish
Choose between polyurethane, varnish and penetrating sealer to use as your finish.
- Apply the sealer
Apply the sealer using a sheepskin applicator. Remove any excess sealer. Allow the surface to dry.
- Buff the floor
Use fine steel wool to buff the floor.
- Vacuum the floor
Vacuum the floor after buffing it.
- Add the finish
Add the finish to the floor, applying as many coats as necessary. Do not walk on the floor for at least 24 hours.
