Protect and preserve your timber with Sikkens BL Natural Decking Oil - Natural 10L, a premium, low-build coating engineered for New Zealand’s climate. This Cetol® BL Natural Decking Oil delivers a natural-looking, matt translucent finish that enhances timber grain while forming a protective, breathable barrier against the elements.

Key advantages you’ll notice on your deck

• Deep, minimal film build—the oil penetrates the wood for lasting protection without forming a heavy surface layer. This keeps the natural feel and texture of the wood intact.
• Microporous, breathable finish—the coating allows the timber to breathe while repelling unwanted moisture, helping to prevent swelling, warping and moisture-driven damage.
• Natural matt translucence—experience a durable, Low-Gloss finish that enhances the timber’s natural beauty without hiding grain or character.
• Quick dry and easy re-coats—optimised for faster turnaround so you can enjoy your deck sooner and schedule timely maintenance.
• Long-lasting protection—formulated to resist mould, UV exposure, and weathering, preserving colour and integrity over time.
• Easy maintenance—designed for straightforward cleaning and re-application, making upkeep simple rather than a chore.
• Eco-conscious and non-toxic—developed with care for the environment and for households, without compromising performance.
• Versatile application—suitable for bare timber or existing intact finishes, making it ideal for upgrades and new builds alike.

What this means in real-world use

• Outdoor decks exposed to NZ’s sun, rain, and humidity stay protected without the finish cracking or peeling as the year wears on.
• The timber’s natural warmth and texture are preserved, giving you a timeless, authentic look that customers notice and guests compliment.
• With its quick-dry profile, you can plan faster maintenance windows and get back to enjoying your outdoor living space sooner.
