Workable

Merbau is strong and durable enough to provide years of service, but it is extremely workable. This is why it has so many different applications.

As mentioned above, you can easily work it with hand tools. You will want to pre-bore all holes for fasteners, though.

Merbau is very easy to finish. It can be stained, painted or polished.

Most people like to allow the dark red or dark brown colour show through to fully appreciate the beauty of this variety of timber.

Durable

In the ground, Merbau is only rated for 5-10 years. But when used above the ground as planks and boards, it is rated to provide 25 or more years of service.

It is resistant to termites and marine borers, though it may be susceptible to lyctid borers. It is only slightly combustible and allowed in bushfire prone areas.

Aesthetics

Merbau is a beautiful timber for decking.

Its natural grain and colour are stunning when presented correctly which is why it is so popular as a decking solution in Queensland.
