Waterlox Vs. Polyurethane

Uncover the Hidden Beauty of Your Wood Surfaces

If you are a woodworker or someone who wants to protect and enhance the natural beauty of wood surfaces, you might have encountered the debate between using Waterlox or polyurethane as a finish. Although both options have their advantages and disadvantages, Waterlox emerges as the top choice for several reasons.

First and foremost, Waterlox, a tung oil-based finish, penetrates deep into the wood grain, providing a protective layer that resists water and moisture. In contrast, polyurethane forms a plastic film on the wood surface, potentially detracting from its natural beauty. Waterlox actually enhances the natural patina and color of the wood, revealing its true beauty.

Waterlox also boasts the advantage of not requiring sanding between coats. As a hardening oil, Waterlox adheres to itself, creating a durable, seamless finish. This means that if you use Waterlox as the initial choice for wood floors in a new home, those floors will never need sanding again. Consequently, Waterlox is a cost-effective and time-saving option for homeowners.

Preserve Your Flooring Investment: Waterlox Offers Unmatched Protection Against Scratches and Damage

Dog owners favor Waterlox, as it resists scratches and damage from pets better than polyurethane. Waterlox’s hardening tung oil is more durable than traditional finishes, withstanding everyday wear and tear while retaining its beautiful finish for years.

While you can use polyurethane on exotic woods like Brazilian cherry and IPE, Waterlox remains the preferred option. Waterlox can function as a pre-sealer on these wood types, ensuring proper adhesion of polyurethane to the surface. As a polymerized resin finish, Waterlox adheres to wood like no other finish.


Save Time and Money on Your Next Project. Waterlox is Safer and More Durable.

Customer reviews and industry experts provide ample evidence supporting Waterlox as a safer and more durable option for specific applications, such as in horse barns. The Material Safety Data Sheet for polyurethane highlights potential hazards harmful to animals, while Waterlox is a natural oil-based finish that offers excellent moisture resistance and a long-lasting protective layer. Many customers have also shared positive experiences using Waterlox on various surfaces, including wood floors and countertops. Although further research is always valuable, the available evidence suggests that Waterlox is a superior choice regarding safety and durability for numerous applications.
