A beautiful hardwood timber species deriving from a few locations around the world, merbau comes from the Kwila tree. The species is found in tropical climates in locations such as Queensland, Australia and Indo Pacific islands like Fiji, and Samoa, as well as Tanzania, India, and Madagascar. Merbau is used mainly for flooring, decking, marine construction, outdoor furniture, music instruments, and more.

This hardwood is popular for its unique beauty, often compared to that of jarrah. It’s known for its unparalleled resilience and usability, along with the resistance to termites and weathering that comes with some merbau timber varieties. The best way to decide on deck boards is by weighing the pros and cons; here is a list of the good, the bad and the ugly that come when decking with merbau.

Advantages of Merbau Timber

Decking experts and carpenters choose merbau for a variety of reasons; the main reasons being its unique beauty, resilience compared to other timber decking, and the variety of uses of merbau, along with its comparatively high resistance to termites and weathering.

More advantages include:

Appearance

Merbau timber is known for its enticing orange golden-brown colour and contrasting sapwood in a soft yellow to ivory white, which can be lightened or darkened with oils based on user preference.

Pro-tip: It’s important to seal and protect your deck; decking oil will increase the merbau deck’s life. There are 2 types of oils in the market: water-based and oil-based. Since merbau contains natural oils, it is recommended to use a water-based oil to protect the function and aesthetics of your timber deck.

If you’re using water-based oil, the deck oiling process will take a day to complete. Oil-based decking products are traditionally used for their penetrative qualities, as they seep into the wood and give it a polished look. These oils are best used on naturally dry wood.

The colour selection for the oils can depend on the colour of your merbau and your desired look; merbau is very easy to lighten or darken based on your preference.

Workability

Merbau is perfect for a range of uses; it’s a versatile timber that can be used for outdoor decking, flooring, cladding, and furniture. Merbau is durable, easy to work with and resistant to insect infestations.

Disadvantages of Merbau Timber

It’s important to not be swayed by only the positives of merbau decking and to consider the whole picture. Once you look past merbau’s attractive qualities, you’ll see that it falls short in a number of areas.

Oily and Messy

Merbau grows in the rainforest and has a high tannin or oil content. The tannin is an oily compound that causes the timber’s colours to bleed when wet. This is something to consider when choosing a decking timber– any materials (paving, walls, concrete) near your deck might be stained if (or when!) your merbau deck bleeds.

Environmental impact

The ugly truth about Merbau timber, like other timbers, is that it causes deforestation of rainforests. This becomes especially problematic when the wood is imported from Asia and continents where the priority for sustainable logging practices is lower. Unsustainable logging practices over the years have made Merbau and other timbers expensive, on your wallet and on the environment.

Pro-tip: If you care about minimising your impact on the earth’s forests, composite decking may be a good option for you. Most composite decks are made of recyclable materials and do not destroy rainforests. This is made easy with brands like Trex, who are committed to sustainability, without sacrificing aesthetics or durability.

Cost

The cost of merbau decking, like all quality timbers, isn’t just a one-off. When decking with timber, you’ll pay the upfront materials cost, the installation cost and the cost of ongoing maintenance.

The hidden costs for merbau come from the maintenance cost; merbau requires staining on a 3 to 6-month basis forever.

What’s Next?

Merbau may be a great decking option for you with natural durability and a beautiful appearance.

We couldn't be more pleased with the result of our new decking built by Dean and his team from Allstyle Build using composite decking sourced from Decking Perth. Dean's customer service and attention to detail was really appreciated and his pricing was value for money given the excellent result. Wouldn't hesitate recommending both Allstyle Build and Decking Perth's products for any decking project.

I had no idea where to start when it came to getting decking installed. I was so pleased when I found Decking Perth because they did all the tricky stuff for me - all I had to do was tell them what I was after and what colour and they did the rest. The contractor I ended up choosing to do the instal was fantastic. Couldn't be happier with my new deck! So thank you!

Decking Perth provide great advice for novice deck buyers by showing you a wide range of products underpinned by knowledge and a conduit to deck builders. A couple of days after we visited Decking Perth one of their preferred contractors provided a very competitive quotation and we engaged AllStyle Carpentry. Decking Perth supplied all materials as they are a One Stop Shop for the contractor. The Modwood Xtteme deck looks fantastic and we could not be happier with it. Thank you Decking Perth as your business supported our thinking and your advice saw the planning come together and we now have a lovely deck.Phill Cribb

Could not recommend Deck Perth more. I had a small area at the front of my house which needed Composite decking supplied and installed. Visited their shop for ideas, then they organised a contractor to attend for a quote to install. All done within 2.5 weeks and over the moon with the end result at a reasonable price, thanks again

I contacted Decking Perth regarding an extension to our current Trex Deck. They took my details and within 4 hours I had been contacted by 2 decking installers and both had attended and quoted within 3 days. Jamie from Elite Decking had the job completed the following week! Lovely team, quiet, clean and tidy workers, on time and on budget, attention to detail exceptional. You cannot tell the difference between the 5 year old deck and the new extension. Highly recommend Elite Decking and Decking Perth.

We were seeking a good quality decking oil for our garden landscaping and out-door shower project. We found the reviews on-line for Cutek Extreme Clear wood preserver were very good and suited us as it is absorbed by the timber thereby ensuring greater life expectancy and a great grain enhancer. In addition re-coating every 18mths to 2yrs appealed as the timber only requires a high pressure wash and a dry off period before re-coating. No sanding required. We chose a New Bronzetone tinter to deepen and enrich the merbau timber grain for an excellent aesthetic finish. Next Project the pool deck!
