Posted on April 27, 2023


Comprehensive Guide to Wood Floor Sanding and Finishing – Restore Your Floors Like a Pro

Wooden floors are a popular choice for homeowners due to their natural beauty, durability, and ability to add warmth and character to any living space. However, over time, these floors can lose their lustre, become scratched, or develop uneven surfaces due to wear and tear. Wood floor sanding and finishing are essential processes to restore and maintain your wooden floors, giving them a fresh and pristine appearance. In this blog post, we will discuss some helpful advice on wood floor sanding and finishing, from preparation to final touches, ensuring a flawless result. Wood Floor Sanding and Finishing
  1. Preparing for Wood Floor Sanding

A crucial first step in the process is preparing the area for sanding. Here are a few tips to ensure that your workspace is ready:
  • Remove all furniture, rugs, and other items from the room.
  • Inspect the floor for any protruding nails, staples, or other debris and remove or hammer them down to avoid damaging your sanding equipment.
  • Fill any significant gaps or cracks in the floor with a suitable wood filler.
  • Thoroughly clean the floor using a vacuum cleaner or a broom to remove any dust or dirt.
  • Seal doors, windows, and vents with plastic sheeting or tape to prevent dust from spreading throughout your home.

  1. Choosing the right sanding equipment

Selecting the appropriate sanding equipment is essential for a successful wood floor restoration. There are several types of sanders available for rent or purchase:
  • Drum sander: A powerful machine used for the initial sanding of larger areas
  • Orbital sander: a more gentle sander, suitable for delicate or intricate surfaces.
  • Edge sander: designed for sanding the edges and corners of the floor where a drum or orbital sander cannot reach.
  • Handheld sanding blocks or pads are ideal for touch-ups and detail work.
When selecting the appropriate sander, consider the size of the room, the type and condition of the wooden floor, and your level of experience. For most projects, a combination of a drum or orbital sander and an edge sander will be sufficient.
  1. Selecting the Right Sandpaper Grit

Using the correct sandpaper grit is vital to achieving a smooth and even finish. Begin with a coarse grit (24–36 grit) to remove any old finish or deep scratches, and then progress to a medium grit (60–80 grit) to remove any remaining imperfections. Finish with a fine grit (100–120 grit) to create a smooth surface, ready for staining or sealing. Sandpaper Grit
  1. Sanding Techniques

Proper sanding techniques will prevent gouging or uneven surfaces.
  • Sand with the grain of the wood, moving in straight, overlapping passes.
  • Keep the sander moving at all times to avoid creating divots or uneven patches.
  • Maintain even pressure on the sander, allowing the weight of the machine to do most of the work.
  • Use a dust mask and ear protection, as sanding can be loud and create a significant amount of dust.

  1. Cleaning and Preparing for Finishing

Once the sanding is complete, vacuum the floor thoroughly to remove any dust and debris. Next, use a microfiber or tack cloth to remove any remaining dust, ensuring the floor is spotless before applying a finish.
  1. Choosing a Wood Floor Finish

There are several types of wood floor finishes available, each with its advantages and disadvantages:
  • Oil-based polyurethane: Durable and easy to apply, this finish provides a warm, amber tone.
  • Water-based polyurethane is a low-odour, quick-drying option that offers a clear finish.
  • Hardwax oil: a natural, eco-friendly choicethat penetrates the wood and provides a matte, natural appearance.
  • Shellac: A traditional finish with a warm, amber tone that is easily repairable but less durable than other options.
  • Lacquer: A durable, high-gloss finish that provides a luxurious, reflective appearance.
Consider factors such as your desired aesthetic, the type of wood, and the room’s purpose when selecting a finish. If you’re unsure which finish to choose, consult a professional or test a small, inconspicuous area of the floor. hardwood floor finishes colors
  1. Applying the Wood Floor Finish

Applying the finish correctly is crucial to achieving a professional, long-lasting result. Follow these steps for a successful application:
  • Ensure the room is well-ventilated and dust-free.
  • If staining the floor, apply the wood stain with a brush or rag, following the wood grain. Allow the stain to dry for the recommended time before applying the finish.
  • Stir the chosen finish thoroughly but gently to avoid creating bubbles. Do not shake the container.
  • Apply the first coat of finish using a high-quality brush or applicator, following the wood grain. Work in small, manageable sections to ensure an even application.
  • Allow the first coat to dry according to the manufacturer’s instructions. Drying times can vary from a few hours to a full day, depending on the finish.
  • Lightly sand the floor with a fine-grit sandpaper (220-240 grit) or a sanding screen to remove any imperfections or raised grain. Vacuum and wipe down the floor with a tack cloth to remove dust.
  • Apply additional coats of finish as needed, following the same process. Most finishes require at least two to three coats for optimum durability and appearance.

  1. Curing and Post-Finishing Care

Allow the finish to cure for the recommended time before replacing furniture or walking on the floor. Curing times can range from a few days to several weeks, depending on the type of finish used. Once the floor is fully cured, follow these tips for ongoing maintenance:
  • Regularly clean the floor with a soft broom, vacuum, or microfiber mop to remove dust and dirt.
  • Avoid using harsh chemicals or abrasive cleaning tools that can damage the finish.
  • Place felt pads or furniture coasters under heavy items to prevent scratches or dents.
  • Use area rugs or runners in high-traffic areas to protect the floor from wear.
  • Recoat the floor every few years, as needed, to maintain its appearance and durability.
