Is DIY Floor Refinishing Right for You?
Before diving into the project, it's crucial to assess whether DIY floor refinishing is the right choice for you. While it's a rewarding endeavor, it's not without its challenges. Consider the following factors:
- Time Commitment: Refinishing floors is time-consuming, often taking several days or even a week, depending on the size of the area.

Step-by-Step Guide to Refinishing Your Floors
1. Preparation: Clearing the Room and Assessing the Floor
Proper preparation is key to a successful floor refinishing project. Start by completely clearing the room of all furniture, rugs, and other items. Remove baseboards and trim carefully, labeling them for easy reinstallation later.
Next, thoroughly inspect the floor for any damages, such as loose boards, protruding nails, or deep scratches. Use a nail set to countersink any protruding nails. Fill any holes, cracks, or imperfections with wood filler, allowing it to dry completely before sanding. For larger gaps between boards, consider using wood shims and wood glue for a more durable repair.
Tip: Take photos of the room before you begin, especially of the trim and baseboards, to help you remember how they were installed.
2. Sanding: Removing the Old Finish and Leveling the Floor
Sanding is the most crucial and labor-intensive part of the refinishing process. It involves removing the old finish and creating a smooth, even surface for the new finish to adhere to. Always wear your safety gear (dust mask, safety glasses, and ear protection) during sanding.
- Drum Sanding: Start with the drum sander and coarse-grit sandpaper (36-40 grit). Sand in the direction of the wood grain, overlapping each pass by about 50%. Avoid stopping the sander while it's in contact with the floor, as this can create dips or gouges. Work your way systematically across the room.
- Edging: Use the edger sander to sand along the walls, corners, and other areas that the drum sander couldn't reach. Use the same grit sandpaper as you used with the drum sander.
- Second Sanding: Switch to medium-grit sandpaper (60-80 grit) and repeat the sanding process with both the drum sander and the edger. This will remove any remaining imperfections and prepare the floor for the final sanding.
- Final Sanding: Use fine-grit sandpaper (100-120 grit) for the final sanding. This will create a smooth, even surface for the finish.
- Detail Sanding: Use an orbital or detail sander with fine-grit sandpaper to get into any remaining hard-to-reach areas or to smooth out any imperfections.
Tip: Change the sandpaper frequently as it becomes clogged with dust. Using sharp sandpaper will ensure a more efficient and even sanding process. Consider renting a drum sander with a built-in vacuum system to minimize dust.

3. Dust Removal: Preparing for Staining or Finishing
Thorough dust removal is critical for a flawless finish. After sanding, use a vacuum cleaner with a HEPA filter to remove all dust from the floor, walls, and any other surfaces in the room. Pay close attention to corners, cracks, and crevices. Empty the vacuum cleaner frequently during this process.
Next, use a tack cloth to wipe down the entire floor, removing any remaining fine dust particles. Repeat this process several times to ensure the floor is completely clean.
Tip: After vacuuming, let the dust settle for an hour or two and then vacuum again. This will help remove any dust that was stirred up during the initial vacuuming.
4. Staining (Optional): Adding Color to Your Floors
If you want to change the color of your floors, staining is the next step. Choose a stain color that complements your home's décor and test it in an inconspicuous area to ensure you like the result. Always stir the stain thoroughly before and during application.
- Apply the Stain: Use a paint brush, applicator pad, or rag to apply the stain evenly to the floor, working in the direction of the wood grain.
- Wipe Off Excess Stain: After a few minutes (refer to the stain manufacturer's instructions for specific timing), use clean rags to wipe off any excess stain. This will prevent the stain from becoming blotchy or uneven.
- Allow to Dry: Allow the stain to dry completely according to the manufacturer's instructions. This may take several hours or even overnight.
Tip: Apply stain in a well-ventilated area and wear gloves to protect your hands. Consider using a stain conditioner before staining to help ensure even stain absorption, especially on woods like pine or maple.

5. Finishing: Protecting and Enhancing Your Floors
Applying a finish is the final step in the floor refinishing process. The finish protects the wood from scratches, wear, and moisture, while also enhancing its natural beauty. There are several types of finishes available, including:
- Polyurethane: A durable and popular choice, available in oil-based and water-based formulas. Oil-based polyurethane provides a warmer tone but has a stronger odor and longer drying time. Water-based polyurethane is low-VOC, dries quickly, and is more environmentally friendly.
- Varnish: Offers good protection and is available in various sheens.
- Lacquer: Dries quickly but is less durable than polyurethane.
Choose a finish that is appropriate for your needs and follow the manufacturer's instructions carefully.
- Apply the First Coat: Use a paint brush or applicator pad to apply a thin, even coat of finish to the floor, working in the direction of the wood grain. Avoid applying too much finish, as this can lead to drips and runs.
- Allow to Dry: Allow the finish to dry completely according to the manufacturer's instructions. This may take several hours or even overnight.
- Sand Lightly (Optional): After the first coat has dried, lightly sand the floor with extra-fine-grit sandpaper (150-180 grit) to remove any imperfections and create a smooth surface for the next coat. Be sure to remove all dust before applying the next coat.
- Apply Additional Coats: Apply two or three additional coats of finish, following the same procedure as the first coat. Allow each coat to dry completely before applying the next.
Tip: Maintain a "wet edge" while applying finish to prevent lap marks. Work in small sections and overlap each pass slightly. Consider using a lambswool applicator for smoother application of polyurethane.
6. Curing and Maintenance
After applying the final coat of finish, allow the floor to cure completely before moving furniture back into the room. Curing can take several days or even a week, depending on the type of finish used. Follow the manufacturer's instructions for specific curing times.
Once the floor is cured, reinstall the baseboards and trim. Clean the floor regularly with a damp mop and a mild cleaning solution specifically designed for hardwood floors. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.
Tip: Place felt pads under furniture legs to protect the floor from scratches. Use rugs in high-traffic areas to reduce wear and tear.
