Tools and Materials Needed

  • Orbital sander
  • 80, 120, and 200 grit sandpaper
  • Staining sponge
  • Goggles
  • Respirator
  • Gloves
  • Paint roller
  • Polyurethane sealer
  • Vacuum
  • Hammer
  • Wood stain
  • Painter’s tape

Step 1 – Check for Loose Nails

Before sanding the floor, inspect the entire surface for any loose nails. Pull out loose, bent or damaged nails and replace them. Ensure that the heads of the nails are flush or slightly lower than the floor surface to avoid any interference when sanding.

Step 2 – Clean and Sand the Floor

Remove anything on top of the floor surface and clean dirt and other debris. Use an orbital sander to sand the floor since other types of sanders are heavy and more difficult to use. An orbital sander can be rented if it is only to be used for this specific project, although it may also be a good investment for homeowners who look forward to using it again in other projects.

Use 80-grit sandpaper during the first sanding application to remove the dull surface layer. Move the sander in a circular motion until every square inch of the floor has been sanded. Sand the entire floor once again using 120-grit sandpaper, and finally with a 200-grit sandpaper to smooth the floor. Clean the dust off the surface with a vacuum cleaner.

Step 3 – Tape All Surfaces that should not be Stained or Sealed

Apply painter’s tape on all surfaces touching or near the floor, such as the stair risers, the door, and the walls. Ensure that the bottom edge of the tape just about touches the floor.

Step 4 – Stain the Floor

Polyurethane sealer is best applied after staining. When staining, always check the manufacturer’s recommended preparation, mixing, and application instructions. Plan an exit path so you never have to walk over the stained floor afterwards. Use a staining sponge or a dry rag to apply the stain evenly onto the pine flooring. Wipe the stain in the direction of the grain always Exit the room and allow the stain to dry for about 24 hours.

Step 5 – Apply the Sealer

Polyurethane sealer looks really good on wooden floors. It also last longer than any other sealers. Wear safety gear to protect the skin and eyes from direct chemical contact, and the lungs from fumes that the sealer emits. The sealer can be applied easily using a paint roller.

Apply the sealer thinly the first time on the entire floor surface. Let it dry for an hour before applying the next coat. Apply several coats until the desired gloss is achieved. Use a paintbrush to seal areas that are hard to reach. Always go with the direction of the grain during application. Do plan an exit path as well. Leave the room and allow the sealer to dry for about 48 hours before walking on it.
