What are the key differences between water-based polyurethane and oil-based polyurethane for wood finishing?

Water-based polyurethane and oil-based polyurethane are two common types of finishes used for wood. The key differences between them are in their drying time, odor, and durability. Water-based polyurethane dries faster, has a lower odor, and is more environmentally friendly. Oil-based polyurethane takes longer to dry, has a stronger odor, and is generally more durable. Ultimately, the choice between the two depends on personal preference and the specific needs of the project.
