Oil-Based Vs. Water-Based Polyurethane Finishes

There are several aspects to consider when deciding between an oil-based polyurethane or a water-based polyurethane. 

Appearance:

Oil-based poly will darken with an orange/yellow tint over time, while water-based poly will remain clear through its lifetime. This amber tint produced by oil-based poly is subtle when applied to a hardwood floor. However, it will still darken over time. Many prefer the “ambering” of oil-based polyurethane as it adds a rich depth charm. However, this is a personal preference.

Smells:

Fumes emitted during the curing time of oil-based poly are much more pungent than those of its water-based alternative that has little to no smell while used. When using and curing oil-based poly, proper breathing equipment is recommended until the area is dry and adequately ventilated. Vacating the site is recommended during the application of oil-based poly.

Durability:

The preferred poly is a much-debated subject when it comes to durability. Oil-based poly, generally preferred for its longevity, is thicker and provides more protection to your hardwood floors. The water-based poly is applied in thinner coats however is a more complex finish. The thickness of the water-based poly can be resolved by adding an additional coat. You can discuss this with your hardwood flooring professional in most instances.

Timeline:

Water-based poly wins the race regarding drying time with an average “walk-on” time of 4 hours. Oil-based poly generally takes 10-12 hours of drying time. With any project, this may vary depending on many environmental factors. 

With many differences between the two finishes, you can always break the tie by contacting a local floor professional to assess the area you are looking to refinish. They can help you determine the best product for your space.
