How to Sand a Wood Floor in 6 Steps: A Comprehensive Guide

Hardwood floors are prized for their natural beauty, durability, and the character they bring to a space. However, over time, these floors can lose their luster due to wear and tear. Fortunately, sanding can restore their former glory, providing a fresh, clean surface ready for refinishing. This blog post will guide you through the process of sanding a wood floor in six steps.

Introduction to Wood Floor Sanding

Wood floor sanding is the process of removing the top layer of a wooden floor using sanding equipment. It’s an essential step in wood floor restoration, capable of removing scratches, stains, and worn-out finishes, leaving a smooth surface ready for a new finish. Remember that sanding is a major undertaking that requires time, effort, and the right equipment. If you’re prepared for a bit of hard work, follow these steps to revitalize your wooden floor.

Step 1: Preparation

Proper preparation is critical for a successful sanding job. First, you’ll need to clear the room entirely. This means removing all furniture, rugs, curtains, and any other items that might get in the way or collect dust. Don’t forget to take down wall hangings and light fixtures that could vibrate off their hooks during the sanding process. Next, inspect your floor for any protruding nails or staples that could potentially damage your sanding equipment. Hammer them down below the surface or remove them entirely. Finally, clean your floor thoroughly to eliminate dust and debris. This can be done using a broom or a vacuum cleaner. Effective Wood Floor Repair

Step 2: Select the Right Sanding Equipment

To sand your wooden floor, you’ll need a drum sander for the main areas and an edge sander for corners and edges that the drum sander can’t reach. Both types of sanders can be rented from a local tool rental store. You’ll also need sandpaper in various grits. Start with coarse-grit sandpaper (about 36 grit) to remove the old finish and major imperfections. Then, you’ll progressively move to finer grits (like 60-grit and 100-grit) to smooth the surface and prepare it for the finish. Safety gear is equally important. Sanding produces a lot of dust, so make sure to have a dust mask, safety goggles, and ear protection. Wood Floor Sanding Machines

Step 3: Coarse Sanding

Start sanding with the drum sander and coarse-grit sandpaper. Remember to sand with the grain of the wood, not against it, to prevent cross-grain scratches that are hard to remove. Move the sander steadily and gradually, ensuring it remains in contact with the floor. Don’t let it sit in one spot while it’s running, or it might dig a hole in the floor. Also, remember to slightly lift the drum before stopping the machine to avoid creating divots. Coarse sanding removes the old finish and levels the floor, but it also leaves visible scratches. These will be smoothed out in the next stages. Efficient herringbone floor sanding by Mr Sander® using Bona belt sander (Effect 2200, Voltage 230, Frequency 50/60) and HEPA-filtered dust extraction.

Step 4: Edge Sanding

After sanding the main areas of the floor, you’ll need to sand the edges and corners using an edge sander. This machine is smaller and lighter than the drum sander, making it suitable for hard-to-reach areas. Just like with the drum sander, start with coarse-grit sandpaper to remove the old finish and then move to finer grits to smooth out the surface. Be careful not to press too hard or move too fast, as the edge sander can leave circular scratches that are difficult to remove.

Step 5: Medium and Fine Sanding

After completing the coarse sanding, you’ll need to move on to medium and fine sanding. This process involves sanding the floor again, first with medium-grit sandpaper (60 grit) and then with fine-grit sandpaper (100 grit). This will remove any scratches left by the coarse-grit sandpaper and create a smooth, even surface ready for the new finish. For medium and fine sanding, you’ll use both the drum sander and the edge sander, just as you did in the previous steps. Remember to keep the sanders moving at a steady pace to avoid creating divots or sanding too much off in one area.

Step 6: Final Touches and Cleanup

After sanding the floor to a smooth finish, the final step is to clean up and prepare the floor for the new finish. Use a vacuum cleaner to remove dust from the floor. Next, wipe the floor with a damp (not wet) cloth or mop to pick up any remaining dust. This step is crucial because any dust left on the floor will get trapped in the finish, creating a rough texture. Once the floor is completely clean and dry, it’s ready for the new finish. You can choose from various finishes, including polyurethane, varnish, and oil, depending on your preferences and the type of wood.

Safety Considerations

Throughout the sanding process, it’s important to ensure your safety. Always wear protective gear, including safety goggles, a dust mask, and ear protection, when operating the sanders. Additionally, ensure the room is well ventilated to reduce the concentration of dust in the air.


Sanding a wooden floor is a labor-intensive process, but it’s also a rewarding one. By following these six steps, you can bring back the natural beauty of your wooden floor, making it look as good as new. Whether you’re planning to restore an old wooden floor or simply want to refresh the look of your existing floor, knowing how to sand a wood floor is a valuable skill. So roll up your sleeves and prepare for some hard work; the results will be well worth it. Remember, though, that sanding is a major project that requires a significant investment of time and effort. If you’re unsure about any step in the process, don’t hesitate to seek professional help. The goal is to ensure your wooden floor is beautifully restored, whether you do it yourself or with the help of a professional. Happy sanding, and here’s to a beautiful wooden floor!
