Blackbutt is another timber that is popular for decking or hardwood flooring in Brisbane. It is native to our area, common in Queensland and New South Wales. It grows quickly and is versatile, making it a perfect plantation timber. It is great for flooring, decking, poles, posts and outdoor framing. Other uses: joinery, furniture, cladding and lining boards.

Know Your Timber: Blackbutt

The heartwood is pale brown and can have a pink tint. The sapwood is a more pale brown. Blackwood has a straight grain with an even, medium texture. Blackbutt isn’t the best timber for painting due to surface checking, but it can still be painted. It takes very well to stain or polish. When it matures, it produces a lot of extractives, making it problematic for gluing.

The sapwood is not susceptible to lyctid borers and the heartwood is resistant to termites. Above ground, Blackbutt has a durability grade of 1, meaning that it has a life expectancy of at least 25 years. In contact with the ground or below it, the durability grade is downgraded to 2, giving it a 15 year life expectancy.

Blackbutt is fire-resistant. It is one of seven hardwoods that the Victorian Building Commission has pronounced suitable for construction in bushfire areas without being treated. Blackbutt can grow up to 50 metres in height with a diameter of 4.1 metres at the trunk. In a natural habitat, Blackbutt protects other trees with its height and its canopy.

Blackbutt is strong, durable and versatile. It is a solid choice for many applications.
