Description
Blackbutt is one of Australia’s most widely used hardwood timbers, and it’s not hard to see why. Native to the eastern seaboard, it’s naturally adapted to Australian conditions — handling everything from coastal humidity to dry inland heat — and brings genuine natural durability to any project without needing chemical treatment to get there. The S&B grade ensures the boards you’re working with have fewer natural characteristics like knots and gum veins than Select grade, giving a more refined and consistent appearance across the finished deck.
Key Features of Blackbutt Decking S&B
- S&B grade decking means fewer natural flaws (knots, borer holes, etc) than Select grade
- Use blackbutt decking in fire-prone areas due to it’s good fire resistance
- Suitable for decking, cladding, joinery & flooring

Why choose Blackbutt Decking S&B?
Blackbutt is an Australian hardwood that’s naturally durable and fire resistant. It has a clean, light aesthetic that suits contemporary Australian backyards particularly well. Unlike darker species like Merbau, Blackbutt’s pale golden tone won’t dominate a space, making it an easy timber to build a design around. The S&B grade gives you a consistently high-quality board with fewer knots and natural features to work around, making installation cleaner and the finished result more uniform.

FAQs
What does S&B grade mean for Blackbutt decking?
S&B stands for 'standard and better', which is the premium grade of timber decking in Australia. S&B boards are held to a higher appearance standard than Select grade, meaning fewer natural characteristics like knots, gum veins and borer holes. The result is a cleaner, more consistent look across the finished deck. Both grades share the same structural integrity and natural durability, the difference is purely in appearance.
Is Blackbutt suitable for fire-prone areas?
Blackbutt has good natural fire resistance, which makes it one of the more suitable timber species for use in bushfire-prone areas compared to many other hardwoods. If your project is in a designated Bushfire Attack Level zone (BAL), check the specific BAL requirements for your area and confirm with your building certifier that Blackbutt meets the requirements for your rating.
How does Blackbutt compare to other hardwood decking species like Spotted Gum or Merbau?
Both are popular hardwood decking species, but they each have a distinct character. Blackbutt is lighter in colour with a clean, subtle grain that suits modern and contemporary aesthetics. Spotted Gum has more colour variation, ranging from light coffee to deep chocolate. Merbau is the darkest of the three with rich red-brown tones. In terms of durability, all three perform well outdoors, with Blackbutt differing from the others due to it's fire-resistance.
Can Blackbutt be used for projects other than decking?
Yes. Blackbutt is suited to decking, external cladding, joinery and general DIY projects. Its clean appearance and workability make it a popular choice across a wide range of residential building applications. Using the same species for both indoor projects and outdoor decking creates a cohesive look between spaces.
What oil or stain should I use on Blackbutt decking?
A penetrating timber oil is the recommended finish for Blackbutt decking. Oil nourishes the timber and protects it from UV fading without forming a surface film that can peel or crack over time. Left without oil, Blackbutt will gradually weather to a silver-grey colour and can be easily damaged from moisture and weather.
How often does Blackbutt decking need to be oiled or washed?
This depends on how much sun and foot traffic the deck receives. As a general guide, oiling twice a year keeps Blackbutt looking its best. Before re-oiling, clean the deck with a purpose-made timber deck wash to remove weathered oil and surface oxidation, then apply fresh oil to the dry surface.
What fixings should I use with Blackbutt decking?
Stainless steel fixings are recommended for all hardwood decking, including Blackbutt. Pre-drilling is recommended given Blackbutt's hardwood density. Driving screws without pre-drilling risks splitting the boards, particularly towards the ends.
Is Blackbutt a sustainably sourced timber?
Blackbutt is native to eastern Australia and is harvested from both native forests and plantation sources. Our Blackbutt decking is proudly PEFC and FSC certified.
