Step-by-Step Refinishing Process

Step 1: Preparation

1. Clear the Area: Remove all furniture, rugs, and obstacles from the room. This will give you ample space to work and prevent damage to your belongings.
2. Safety First: Put on your safety gear – dust mask, safety goggles, and ear protection – to safeguard yourself from dust and noise.

Step 2: Sanding

1. Start with Coarse Grit: Begin sanding with the coarsest grit sandpaper on the drum sander. Work in the direction of the wood grain, moving slowly and evenly across the floor. Avoid lingering in one spot to prevent uneven sanding.
2. Edge Sanding: Use the edge sander to sand corners, edges, and areas the drum sander couldn’t reach. Be careful not to tilt the sander, as it can leave grooves in the wood.
3. Medium Grit Sanding: Repeat the sanding process with medium grit sandpaper using both the drum and edge sanders. This step will remove the scratches left by the coarse grit sandpaper.
4. Fine Grit Sanding: For a smooth finish, use fine grit sandpaper to sand the entire floor once again. This will prepare the wood for staining and sealing.
5. Vacuum and Tack Cloth: Thoroughly vacuum the floor to remove all dust and debris. Then, use a tack cloth to wipe the surface and ensure it’s clean.

Step 3: Staining (Optional)

1. Choose a Stain: If you wish to change the color of your hardwood floors, select a wood stain that complements your desired look.
2. Apply the Stain: Using a brush or rag, apply the wood stain in the direction of the grain. Wipe off excess stain with a clean rag after a few minutes to achieve your desired color intensity.
3. Allow to Dry: Let the stain dry according to the manufacturer’s instructions. This usually takes around 24 hours.

Step 4: Sealing

1. Choose a Sealer: Decide between water-based or oil-based polyurethane sealer. Water-based is faster drying and emits fewer fumes, while oil-based offers a richer finish.
2. Apply the Sealer: Stir the sealer gently to avoid bubbles. Using a brush, roller, or lambswool applicator, apply a thin, even coat of sealer, working in the direction of the wood grain. Allow the sealer to dry as per the manufacturer’s guidelines.
3. Buffing (Optional): Between coats, you can lightly sand the surface with fine grit sandpaper and then vacuum and tack cloth before applying the next coat. This step helps achieve a smoother finish.
4. Multiple Coats: Apply at least two to three coats of sealer for optimal protection and sheen. Allow each coat to dry before applying the next.

Step 5: Final Touches

1. Cure Time: Allow the final coat of sealer to cure according to the manufacturer’s instructions. This can take several days to a week.
2. Replace Furniture: Once the floor is fully cured, you can move your furniture back into the room.
