What Is Hardwood Floor Refinishing?

Updated 03/18/2025

Hardwood floor refinishing restores the beauty of your hardwood floors by removing old finishes, sanding the surface to smooth out imperfections, and applying a fresh protective finish. Refinishing hardwood floor revitalizes the floor's shine, durability, and overall appearance without the need to replace the entire floor.

The Steps of Hardwood Floor Refinishing

Step One: Preparation

Clear the room by moving all furniture and items out. Remove fabrics, such as drapes and lamp shades, and anything that can trap dust, like pictures or register covers. Be sure to remove any nails from the floor and take off any shoe molding. Cover vents, doorways, and light fixtures to prevent dust buildup. This is also the time to inspect the floor for any holes or gouges, which can be filled with wood filler.

Step Two: Sanding

Rent a sanding machine and wear the appropriate safety gear. You'll need three types of sandpaper: coarse (30-40 grit), medium (50-60 grit), and fine (80-100 grit). Sand the floor with each grit, starting with the coarse and finishing with the fine, and don't forget to sand the edges and corners with smaller sanders. Once done, vacuum the room and wipe the floor with a damp mop.

Step Three: Buffing

Buffing is typically used to remove an old coating and apply a new one. If the floor feels rough after sanding, you can use 120-grit paper, but this step is usually unnecessary.

Step Four: Cleaning

After sanding, thoroughly vacuum the room to remove dust. Wipe down the walls, windows, and any uncovered surfaces. Finally, wipe the floor with mineral spirits to remove any remaining stains and prepare it for staining or finishing.

Step Five: Staining (Optional)

If you want to change the color of the wood, you'll need to apply stain. Follow the manufacturer's instructions for proper application.

Step Six: Finishing/Sealer

Apply a protective finish, typically polyurethane, to seal the floor and protect it from wear and tear. There are different types of wood finishes to choose from, such as oil-based or water-based polyurethane. Depending on the type, you may need to apply multiple coats. Be sure to allow each coat to dry and cure before applying the next.

Always start at the farthest point from the door and work your way back to avoid getting stuck in a corner.
