The Benefits of Merbau Timber Decking

Merbau timber decking delivers that classic Aussie backyard feel. It isn’t just about looks, it’s about long-term performance. From building poolside decks to alfresco dining areas, our team is here to bring your full backyard transformation to life.

Rich and Warm Aesthetics
Merbau adds warmth and character to any outdoor area with deep reddish-brown hues and unique grain patterns. It weathers gracefully if left untreated or you can oil it to keep that rich colour shining.

Durable and Long-lasting
Naturally dense and resistant to wear, merbau timber handles knocks, spills, and heavy foot traffic with ease. It’s perfect for families or anyone who loves entertaining guests outdoors.

Weather-resistant
Merbau decking performs well in Sydney’s climate. It resists shrinking, cracking, and warping whether it’s baking in the sun or soaking in the rain during a storm.

Bushfire and Termite Resistance
Merbau is one of the few timbers rated for use in bushfire-prone areas (BAL 29 compliant), plus it’s naturally resistant to termites, so there are no nasty surprises down the road.

Low Maintenance
A quick clean and occasional oiling is all it takes to keep a Merbau deck looking sharp — ideal for homeowners who want long-term performance without constant upkeep.

Versatile Design Appeal
Merbau decking fits in traditional and modern spaces alike. It lends well to a sleek and minimalist layout or a classic hardwood look.

Common Questions About Merbau Decking

With regular maintenance, like cleaning, oiling, and checking for signs of wear, Merbau decking can easily last between 25 and 40 years in Sydney’s climate.
Freshly installed Merbau decking can bleed tannins — the natural oils in the timber. They can stain nearby walls, paving, or concrete. You can minimise tannin bleed by pre-washing or leaching the boards before installation, and applying good-quality sealing oil after installation.
Merbau is one of the few hardwoods that meet the Bushfire Attack Level (BAL) 29 rating, meaning it’s suitable for use in many bushfire-prone areas across NSW. Our team can assist with this during your consultation.
Apply the first coat of oil after installation and re-oil every 6-12 months, depending on how much sun and weather exposure your deck receives. Use a penetrating decking oil designed for hardwoods, and make sure the deck is clean and dry before application.
Yes, absolutely! Merbau timber is versatile and easy to work with. You have the freedom to choose board widths and lengths to suit your layout, feature inlays or steps, and different finishes that range from a natural matte to a deeper stained look.

Yes, we do! Merbau is a fantastic choice for privacy screens, feature fences, and garden dividers thanks to its strength, stability, and good looks. You can match your decking and screening for a consistent outdoor look. Check out our fencing and screening services or contact us to discuss how our team can add this to your decking project.

Yes, but do it with care. When using a pressure washer, use a low to medium pressure setting (under 1,500 PSI), keep the nozzle at least 30cm from the surface to avoid gouging the timber, and spray in the direction of the grain. Overuse or high pressure can strip the protective oils and damage the timber surface, so we recommend pressure washing only when needed.
