What is the most durable outdoor wood finish?

Epoxy finishes are a popular choice for boat builders due to their ability to create a thick, water-impermeable barrier on wood surfaces. However, they lack UV protection, which can cause the epoxy to yellow and crack. To prevent this, it is necessary to overcoat the finish with a spar varnish or polyurethane with UV inhibitors. This makes epoxy the most expensive and labor-intensive choice. Some epoxy manufacturers offer spar varnishes that work with their products, eliminating concerns about compatibility.

Epoxy finishes are best on flat surfaces easily accessible from all sides, but avoid projects with complex moldings, crevices, or closely spaced slats. To bond with epoxy, sandpaper or a round-over bit in the router should be used, and smooth surfaces should be sanded.

What is better than polyurethane?

On the other hand, polyurethane is more expensive, difficult to work with, more flexible, and more durable.

Which polyurethane is best for outdoor use?

Polyurethane is suitable for both interior and exterior use, with oil-based and water-based options suitable for interior projects.

Oil-based polyurethanes are typically more durable, while some water-based formulas are designed for outdoor use. Polyurethane finishes come in various gloss levels: high-gloss, semi-gloss, satin, and matte. High-gloss finishes are shiny and reflective, enhancing wood’s grain and color but displaying scratches and imperfections.

Semi-gloss finishes have a slightly less reflective surface, offering a balance between shine and practicality, commonly used for furniture and cabinetry. Satin finishes have a soft sheen, hiding imperfections better than glossier finishes, and are ideal for projects with a subtle, rustic appearance.

A good polyurethane coating can outlast furniture, potentially lasting 20 or more years in cold and snowy areas. For areas with less severe winters, a coating that remains durable is still valuable. Regular maintenance is simple and inexpensive, as long as it is done every few years. Regular maintenance extends the furniture’s life and ensures it remains looking great.
