Apply Protective Sealer

What happens in this clip

After the stain has completely dried, apply the protective sealer. The video recommends a semi-gloss finish for a balanced shine and good durability. Use a T-bar applicator with a clean lambswool pad to apply thin, even coats of sealer. Work systematically across the room, ensuring full coverage without creating puddles or missed spots. Typically, two to three coats are recommended for durability, with light sanding (e.g., with 220-grit sandpaper) between coats after they have dried, followed by thorough cleaning to remove dust. Allow the final coat to cure fully before placing furniture back on the floor, which can take several days to a week.

Goal: Protect the wood and provide the desired sheen

About the full video

This project provides a comprehensive guide on how to refinish old hardwood floors, specifically addressing the challenges of removing old carpet adhesive, filling gaps, and applying stain and protective sealer. It covers the process from initial aggressive sanding to the final application of a semi-gloss finish, ensuring a durable and aesthetically pleasing result.

Step 4 of 5: Apply a Protective Coating or Sealant

For hard flooring materials like tile or sealed wood, apply a clear, durable floor sealant according to the manufacturer's instructions. This typically involves applying thin, even coats using a brush or roller. Allow adequate drying time between coats and before allowing foot traffic. Ensure good ventilation during application and drying.
