You have got a bare patch of yard, a few free weekends and a picture in your head of the perfect deck. But the big question is. Do you go for classic merbau, or a modern composite board?

It is a fair one, because the two couldn’t be more different. One is dense, red-brown hardwood with natural grain that changes from board to board. The other is manufactured board that asks very little of you once it is down.

So let’s put WPC decking vs merbau decking side by side and see which one suits your budget, your backyard and the way you actually live. 

What is WPC Decking?

WPC stands for wood-plastic composite. The boards are made from wood fibre and polymer and shaped in a factory. So every board comes out with the same colour and finish.

At Titan Trade Centre, our main WPC range is Terra Deck. These are co-extrusion boards, which means a solid polymer shell is bonded around the composite core. Terra Deck comes in Teak Wood, Ancient Wood, Red Merbau, Steel Grey and Vanta Black. We also stock 3D Embossed WPC boards, which add a textured surface and available in different colours.

The main WPC decking pros and cons come down to look, upkeep and cost, and we’ll get to each of those below.

What is Merbau Decking?

Merbau is a dense tropical hardwood native to Southeast Asia and the Pacific. It is one of the most familiar decking materials in Australia. It has a warm red-brown colour and natural durability for above-ground outdoor use. Our Merbau decking comes in 140 x 19 mm boards.  

One thing to know before you buy: fresh merbau can bleed tannins when it is new. Early rain can leave brown streaks on nearby paving or concrete. So it’s worth planning for.

Comparing WPC and Merbau Decking

Before you decide which option is right for you, compare the two. Here’s a simple comparison between the two:

	WPC	Merbau
Look	Even colour and finish on every board	Natural grain and colour that vary board to board
Made from	Wood fibre and polymer with a protective outer polymer shell.	Natural tropical hardwood
Upkeep	Wash as needed	Regular oiling
Rot and pests	Doesn’t rot	Naturally resistant to decay and termites
Ongoing costs	Cleaning supplies	Oil, applicator and your time.

Merbau Decking Maintenance vs WPC: What Upkeep Really Looks Like

Merbau needs regular cleaning and re-oiling to hold its colour. Set aside a day or a weekend each time, depending on the size of your deck. You will need decking oil, an applicator and a stretch of dry weather.

WPC is much simpler. A sweep and a wash with mild soapy water keeps most boards looking fresh, with no oiling, sealing or staining. It is low maintenance, not no maintenance. Leaves and dirt still collect in the gaps, so a regular clean pays off.

So ask yourself how you’d rather spend a free Saturday.

WPC vs Timber Decking Cost: What You’ll Really Pay?

It’s tempting to compare price tags and call it done. Don’t. A board price isn’t a deck price.

Start with the boards, but compare them per metre or per square metre covered, since the widths and lengths differ. Then add the extras: framing, clips or fixings, fascia boards for hollow WPC, and wastage. On the timber side, add oil, applicators and your time on an ongoing basis.

Upfront, the gap isn’t fixed. Our WPC ranges sit at different price points, so depending on the board you pick, the difference can be smaller than you’d expect. Over the years, the oil and labour of merbau need to tip the balance for many people. It’s worth pricing both options over ten years, not just on day one.

How Do They Handle Melbourne’s Weather?

Melbourne can go from a 40-degree afternoon in January to a cold, wet week in July. But your deck copes with all of it. 

Merbau is a dense hardwood and holds up well outside. But the sun is what gets it. UV bleaches the colour and dries out the surface. If you stop oiling it, the boards fade to a silvery grey.

Both materials expand and contract a little as the temperature changes, so leave the recommended gaps between the boards when you lay them. 

So which is the best for a Melbourne backyard? It comes down to your budget, how much shade you get and how much upkeep you’re happy to take on.

Which Suits Your Backyard?

At its heart, composite decking vs hardwood is a question of time versus texture.

WPC is worth a look if:

• Your deck is a busy family space, and you’d rather not schedule upkeep.
• You want a dark, modern look, like Vanta Black or Steel Grey.
• You’d like every board to match.

Merbau is worth a look if:

• You enjoy working with real timber and don’t mind an oiling routine.
• You like the idea of finishing the deck yourself.
• You want the character that only a natural hardwood has.

Love the merbau colour but not the oiling? Terra Deck Red Merbau gives you that deep red-brown tone in a composite board. And stand back from your house for a minute: warm timber against brick, or slate-grey boards against render? Sometimes the house makes the call for you.
