Refinishing hardwood floors involves sanding down the existing finish to bare wood, repairing any damages, and applying a new finish. This process can be time-consuming and requires careful attention to detail, but it is a great DIY project that can save you money in the long run.

A Guide to Refinishing Hardwood Floors is prepared, we will walk you through the steps to refinish hardwood floors, from sanding and preparing to selecting and applying the floor finish.

Step 1: Prepare the Room

Before you begin sanding, you need to prepare the room. Remove all furniture, rugs, and curtains from the room. Cover any vents or openings with plastic sheeting to prevent dust from entering other parts of your home.


Step 2: Remove the Existing Finish

The first step in refinishing your hardwood floors is to remove the existing finish. Start by renting a floor sander from your local hardware store. You will need to choose the appropriate grit sandpaper for your sander. Typically, you will need to use three different grits of sandpaper, starting with a coarse grit and finishing with a fine grit.

For the first pass, use 36- or 40-grit sandpaper. This will remove the existing finish and any deep scratches or stains. Be sure to wear a dust mask and eye protection during this step, as the dust can be harmful.

After you have completed the first pass, vacuum and sweep the floor thoroughly to remove any dust or debris. Then, move on to the next grit sandpaper. For the second pass, use 60- or 80-grit sandpaper. This will smooth out any rough patches left by the first pass. Finally, for the third pass, use 100- or 120-grit sandpaper to create a smooth surface.

Step 3: Repair Any Damages

After sanding hardwood floor, inspect the floor for any damages, such as cracks, holes, or gaps. Fill any gaps or cracks with wood filler and sand them down until they are flush with the surrounding wood. If there are any deep scratches or gouges, you may need to use a wood patching product to fill them in.

Step 4: Clean the Floor

Once you have repaired any damages, clean the floor thoroughly. Vacuum and sweep the floor to remove any dust or debris. Then, wipe the floor with a damp cloth to remove any remaining dust or residue.


Step 5: Apply the Finish

Now that the floor is sanded and cleaned, it’s time to apply the finish. There are several types of finishes available, including oil-based, water-based, and wax-based. Each type of finish has its own pros and cons, so it’s important to choose the one that best suits your needs.

Oil-based finishes are the most durable and long-lasting, but they can take longer to dry and emit strong fumes. Water-based finishes are eco-friendly and dry quickly, but they are less durable than oil-based finishes. Wax-based finishes provide a natural and warm look to the floor, but they require regular maintenance to keep them looking their best.

To apply the finish, start by applying a coat of sealer to the floor. This will help to protect the wood and prevent the finish from soaking into the wood too quickly. Then, apply the first coat of finish using a brush or roller, following the grain of the wood. Be sure to use long strokes and avoid going over areas that have already been coated.

After the first coat has dried, lightly sand the floor with fine grit sandpaper to remove any imperfections or bubbles in the finish. Vacuum and sweep the floor again to remove any dust or debris. Then, apply a second coat of finish, following the same process as the first coat.

Repeat this process for a third coat, if desired. Be sure to allow each coat of finish to dry completely before applying the next one. This can take anywhere from 2-4 hours, depending on the type of finish you are using.


Step 6: Allow the Finish to Cure

After applying the final coat of finish, allow the floor to dry completely. This can take up to 24-48 hours, depending on the type of finish you are using. Be sure to keep foot traffic to a minimum during this time, and avoid placing furniture or rugs on the floor until the finish has cured completely.


Step 7: Maintain the Finish

To keep your newly refinished hardwood floors looking their best, it’s important to maintain the finish. This includes regular cleaning and maintenance, such as sweeping or vacuuming the floor regularly to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaners on the floor, as this can damage the finish.

It’s also important to avoid dragging heavy furniture or sharp objects across the floor, as this can scratch or dent the wood. Use furniture pads or felt pads under the legs of furniture to protect the floor from scratches.

In addition, consider using area rugs or runners in high-traffic areas to help protect the floor from wear and tear. Be sure to choose rugs with non-slip backings to prevent them from sliding around on the floor.
