Timber Decking: All You Need to Know About Merbau/Kwila

When it comes to timber decking, a lot of homeowners in the Brisbane area don’t bother with any species of timber except Merbau, also known as Kwila. That’s because Merbau is one of the most popular timber varieties for timber decking, not only in Brisbane, but across Australia.

The short version: Merbau is durable, strong and looks great, whether clear coated, stained or painted. Here’s why.

Merbau is local, but also grows in Papua New Guinea, the Pacific Islands, Southeast Asia and Africa. A mature Merbau tree can be from 40-60m tall with a trunk diameter of 1.2-1.5m. It is known for its strength and durability, making it popular for marine, construction and engineering applications.

When it is freshly cut, Merbau heartwood has an orange-brown colour. Colour can vary greatly from board to board. Most Merbau has small yellow mineral deposits, making it even more distinctive. The grain in Merbau is interlocked with straight elements. The colour deepens as Merbau ages. It is seen as extremely attractive, especially when backsawn.

The sapwood, however, is pale yellow, white or buff coloured. It is susceptible to lyctid borer attack if not treated. Most people like the heartwood. Not only is it resistant to lyctid borers, it is also resistant to termites. When kiln-dried, Merbau seasons well, with minimal shrinkage, movement or degradation.

Merbau is strong and durable, but it is also one of the most workable timbers you will ever use. Not only is it popular for timber decking and timber flooring, it is also popular for joinery and more detailed work such as musical instruments, cabinets, boats and carving.
