Why Sand Your Wood Floorboards?

There are several reasons why you may want to sand your wood floorboards:
  1. Reviving Old Floors: Over time, wooden floors can become dull, damaged, or stained. Sanding can remove these imperfections and restore the original beauty of the flooring.
  2. Preparing for New Finishes: Sanding is an essential step in preparing your floor for refinishing, as it creates a smooth, even surface for the new finish to adhere to.
  3. Smoothing Uneven Surfaces: Sanding can level out uneven floorboards, removing high spots and filling in low spots for a consistent, level surface.
  4. Removing Old Finishes: If you want to change the finish on your floor, sanding is necessary to remove the old finish and prepare the surface for the new one.
  5. Increasing Durability: Properly sanded and refinished floors can last for decades, making them a cost-effective and eco-friendly choice for homeowners.

  1. Drum or orbital sander (rent or purchase)
  2. Sandpaper in various grits (coarse, medium, and fine)
  3. Edge sander or hand sander
  4. Vacuum cleaner or shop vacuum
  5. Dust mask and safety goggles
  6. Ear protection
  7. Plastic sheeting or drop cloths
  8. Painters’ tape

A Step-by-Step Guide to Sanding Wood Floorboards

Step 1: Prepare Your Work Area
  1. Clear the room of all furniture, rugs, and other items.
  2. Inspect the floor for any protruding nails or staples, and either remove them or hammer them down.
  3. Use plastic sheeting or drop cloths to cover any vents, doorways, or windows to prevent dust from spreading throughout your home.
  4. Use painters’ tape to secure the plastic sheeting or drop cloths in place.
Prepare Your Work Area Step 2: Choose the Right Sander and Sandpaper
  1. Select a drum or orbital sander for the main floor area. Drum sanders are more aggressive and work faster, but they can also be more difficult to control. Orbital sanders are less aggressive and provide a smoother finish, but they may require more passes to remove the old finish.
  2. Choose sandpaper grits for your project. Start with a coarse grit (36–60) to remove old finishes and level the floor. Move to a medium grit (80–100) to smooth out the surface, and finish with a fine grit (120–150) for a polished look.
Choose the Right Sander and Sandpaper Step 3: Sand the floor
  1. Put on your dust mask, safety goggles, and ear protection.
  2. Install the coarse sandpaper on your sander and start in a corner of the room, working with the grain of the wood.
  3. Move the sander slowly and evenly across the floor, overlapping each pass by about one-third of the sander’s width. Keep the sander moving to prevent gouging the floor.
  4. As you complete the first pass with the coarse grit, inspect the floor for any remaining imperfections, high spots, or stubborn finishes. Repeat the process with the coarse grit, if necessary.
  5. Once you’re satisfied with the results, switch to medium-grit sandpaper and sand the entire floor again. This will smooth out any rough spots and further level the surface.
  6. Finally, use the fine-grit sandpaper for the last pass, creating a smooth, polished surface that’s ready for finishing.

Step 4: Sand the edges and corners.
  1. Use an edge sander or hand sander with the same progression of sandpaper grits to sand the edges and corners of the floor. Make sure to blend the edges with the main floor area to create a consistent appearance.
  2. Be cautious when sanding near baseboards or moulding to avoid damaging them. You can also use painters’ tape to protect these areas.
Sand the edges and corners. Step 5: Clean Up and Fill Gaps
  1. Thoroughly vacuum the entire floor with a shop vacuum or vacuum cleaner, making sure to remove all dust and debris.
  2. Inspect the floor for any gaps, cracks, or holes. Use a putty knife to fill these areas with wood filler, ensuring a smooth, even surface.
  3. Allow the wood filler to dry according to the manufacturer’s instructions, then lightly sand the filled areas with fine-grit sandpaper.
  4. Vacuum the floor again to remove any dust from the sanding and filling process.
  5. Wipe the floor with a tack cloth or microfiber cloth to ensure it’s completely clean and dust-free before applying the finish.
Clean Up and Fill Gaps Step 6: Apply Your Finish
  1. Choose a polyurethane finish or another preferred floor finish to protect and enhance the appearance of your sanded wood floorboards.
  2. Follow the manufacturer’s instructions for application, typically using a paintbrush or floor finish applicator.
  3. Apply the finish in thin, even coats, working with the grain of the wood and ensuring full coverage.
  4. Allow the finish to dry according to the manufacturer’s instructions before applying additional coats. Most floors will require two to three coats for optimal durability and appearance.
  5. Once the final coat is dry, carefully remove the plastic sheeting or drop cloths and painters’ tape, and reinstall any removed baseboards or moulding.
  6. Allow the finish to cure completely (usually 24–48 hours) before moving furniture back into the room and resuming normal use.
