DIY steps
- Before starting, ensure the room is well-ventilated, and wear a dust mask, safety glasses, and gloves to protect yourself from dust and chemicals. Clear the room of furniture, and cover the walls, baseboards, and any remaining furniture with plastic or drop cloths.
- Begin by inspecting the floor for any nails or staples that need to be countersunk, and fill any gaps or holes with wood filler. Allow the filler to dry according to the manufacturer's instructions.
- Use a drum sander to sand the entire floor, working in sections to maintain even coverage. Start with coarse-grit sandpaper (about 80-100) and progress to finer grits (120-150) for a smoother finish.
- Use an edger sander to sand along the edges and in corners where the drum sander cannot reach. Be careful not to gouge the wood.
- Vacuum and tack-clean the floor after final sanding and before applying polyurethane. Apply polyurethane with a paint roller in sections, following the manufacturer's instructions for application, drying, and between-coat preparation.
- Allow the polyurethane to dry, then inspect the floor for any imperfections. Apply additional coats as needed, following the manufacturer's instructions.
- After the final coat has fully cured according to the manufacturer's instructions, inspect the finish and replace the furniture and fixtures.
