DIY Guide – How To Sand Wooden Floors and Floorboards

Sanding wooden floors and floorboards can give your home a refreshed, polished look and can be a cost-effective alternative to replacing old or damaged flooring.

Sanding wooden floors is also a great way to get rid of scratches, dents, and stains, leaving your floorboards looking as good as new.

In this DIY guide, we’ll show you how to sand wooden floors and floorboards to achieve a professional finish.

Before You Start:

  • Prepare the Room: Remove all furniture and cover any areas that cannot be moved with plastic sheeting or dust sheets. Make sure you have adequate ventilation, as sanding produces a lot of dust.
  • Check for Damages: Inspect the floor for any damages or areas that need to be repaired. Fill any cracks or holes with wood filler and sand smooth.
  • Selectthe Right Sandpaper: The type of sandpaper you use will depend on the type of wood and the finish you are looking to achieve. A rough sandpaper (such as 40-grit) is used for removing old finishes, while finer sandpaper (such as 80-grit) are used for smoothing out rough areas.

Steps to use sandpaper to sand wooden floors:

  1. Start Sanding: Start by sanding along the length of the floorboards with a rough sandpaper (such as 40-grit). Move slowly and use gentle pressure to avoid sanding through the wood. Once you have removed the old finish, switch to a finer sandpaper (such as 80-grit) and repeat the process until you have a smooth surface.
  2. Change Directions: Once you have finished sanding in one direction, change the direction and repeat the process. This helps to ensure an even sanding and removes any visible sanding marks.
  3. Sand Edges and Corners: Use a sanding block to sand the edgesand corners, as these areas are often difficult to reach with a floor sander.

  1. Vacuum and Clean: Vacuum the floor to remove any sawdust, then use a damp cloth to wipe away any remaining dust.
  2. Apply a Finish: Once you have finished sanding, you can choose to apply a finish such as varnish, wax, or oil to protect the wood and enhance its natural beauty. Follow the manufacturer’s instructions for application and drying time.
