That's an excellent question! Protecting your wooden outdoor bench is crucial for its longevity and beauty. While there's no single "best" brand for everyone, I highly recommend a few top performers based on durability, ease of application, and value.
For a clear, penetrating oil finish that enhances wood grain, Ready Seal is a favorite among professionals. It's incredibly user-friendly—no priming needed, and it's forgiving to apply without lap marks. For robust waterproofing and mildew resistance, Thompson's WaterSeal is a classic, trusted name. Their clear waterproofing sealants are excellent for repelling water on benches.
If your bench sees intense sun, consider a sealant with UV blockers. Cabot Australian Timber Oil offers rich, natural tones and superior protection against sun and rain. For a durable, film-forming finish that sits on the wood surface, Helmsman Spar Urethane by Minwax provides a tough, glossy shield, ideal for high-wear areas.
My top tip? Always start with a clean, dry, and sanded surface. Reapply your chosen sealant every 1-2 years for continuous protection. Your bench will thank you for seasons to come!
