Name a common finish used for wood flooring?

Polyurethane is a popular finish used for wood flooring due to its durability and resistance to scratches, moisture, and wear. This finish forms a protective layer over the wood, making it ideal for high-traffic areas where flooring is subject to significant use. Polyurethane finishes can be found in both oil-based and water-based formulations, allowing for flexibility depending on the desired drying time, appearance, and application method. The versatility offered by polyurethane makes it a preferred choice among homeowners and contractors for achieving long-lasting and visually appealing wood floors.
