Choosing the right finish for your wooden garden bench is crucial for battling sun, rain, and frost. For maximum durability, penetrating oils like teak oil offer good moisture resistance but require annual reapplication. For a harder, protective film, exterior-grade varnishes or polyurethanes are superior, with spar urethane being the top choice for its flexibility and UV inhibitors that prevent cracking and yellowing. For ultimate protection, a two-part marine-grade epoxy sealant, followed by a UV-resistant topcoat, creates an almost impervious barrier. Regardless of your choice, proper preparation—sanding and cleaning—is key. The most durable finish is the one you maintain; regular inspection and timely touch-ups will ensure your bench lasts for decades.
