What are the differences between water-based polyurethane and oil-based polyurethane, and which one is better for my project?

Water-based polyurethane and oil-based polyurethane are both types of finishes used to protect and enhance wood surfaces.

Water-based polyurethane dries faster, has a lower odor, and is easier to clean up with water. It also has a clear finish that does not yellow over time.

Oil-based polyurethane takes longer to dry, has a stronger odor, and requires mineral spirits for cleanup. It has an amber hue that can deepen over time.

The choice between the two depends on your project needs. Water-based polyurethane is better for indoor projects where a clear finish is desired and quick drying time is important. Oil-based polyurethane is better for outdoor projects or those that require a deeper, amber finish.
