Master the Art of Wood Floor Sanding and Finishing with Our Top 9 Expert Tips

Wooden floors have been a popular choice for homeowners for centuries, and for good reason. They are durable, aesthetically pleasing, and timeless. However, even the most well-maintained wooden floors will eventually require refinishing to restore their original beauty. In this blog post, we’ll explore the top seven wood floor sanding and finishing tips to help you achieve a flawless look.

1. Choose the right type of sandpaper.

The first step in any floor sanding project is selecting the appropriate sandpaper. Sandpaper is available in various grits, with lower numbers indicating a coarser texture and higher numbers a finer one. Start with coarse-grit sandpaper (such as 36-grit) to remove the old finish and level out any imperfections in the wood. Gradually work your way up to finer grits (60-grit, 80-grit, and finally 100-grit) for a smooth and even surface.

2. Prepare your space.

Before you begin the sanding process, it’s essential to prepare your space adequately. Remove all furniture, rugs, and other items from the room, and cover any vents, outlets, or switches with plastic to prevent dust from entering. Seal off the room with plastic sheeting to minimise dust migration to other areas of your home. Finally, wear a dust mask, ear protection, and safety goggles to protect yourself from dust and noise during the sanding process.

3. Properly use a floor sander

Using a floor sander can be intimidating for first-time users, but with proper technique and practise, you’ll quickly become comfortable. Hold the sander with both hands, applying even pressure as you move it back and forth across the floor. Keep the sander in motion at all times to avoid creating divots or uneven spots. Work in a consistent pattern, overlapping each pass by a few inches to ensure even coverage.

4. Don’t forget the edges.

While a floor sander is excellent for covering large areas, it often can’t reach the edges of your room. For these areas, use an edge sander or a random orbital sander with the same grit progression as the main floor. Be sure to blend the edges with the rest of the floor so there are no visible transitions.

5. Vacuum and tack

After sanding, it’s crucial to thoroughly remove all dust and debris from the floor. Vacuum the entire area using a shop vacuum with a soft brush attachment, taking care to get into corners and crevices. Then, use a slightly damp microfiber cloth or tack cloth to wipe down the entire floor. This step will ensure a clean surface for the new finish to adhere to.

6. Choose the right finish.

There are several types of finishes available for wood floors, including polyurethane, varnish, and penetrating oil. Each type has its advantages and disadvantages, so it’s essential to research and select the best finish for your specific needs. Polyurethane is the most common and durable finish, providing a protective layer that resists wear and tear. Varnish offers a high-gloss appearance but may be more prone to scratches. Penetrating oil finishes enhance the wood’s natural beauty and offer some protection, but they require more frequent maintenance.

7. Apply the finish.

Applying the finish is the final step in your wood floor refinishing project. Ensure the room is well-ventilated, and wear a respirator mask to protect yourself from fumes. Use a high-quality natural bristle brush or a lambswool applicator to apply the finish, working in the direction of the wood grain. Apply thin, even coats, allowing each
