140x19 Merbau Decking

140x19 Merbau Decking Select Grade KD is a premium hardwood decking solution designed for Australian outdoor conditions. Known for its durability, stability, and rich reddish-brown colour, Merbau is naturally resistant to termites, decay, and harsh weather.

The wider 140mm profile creates a modern, seamless deck appearance with fewer joins, making it ideal for large decks, alfresco areas, and commercial projects. Kiln-dried (KD) for enhanced stability, this decking minimises movement and ensures long-term performance.

Perfect for builders and homeowners alike, Select Grade Merbau offers a cleaner finish with minimal knots and defects. Easy to install and maintain with regular oiling, it delivers a long-lasting, high-end outdoor living space.

Frequently Asked Questions

Why choose 140mm decking over 90mm?

The wider 140mm board covers your deck area with fewer joins and fixing points, giving a more modern, seamless look — popular for larger decks and alfresco areas.

What's the difference between Merbau and Pacific Jarrah decking?

Both are durable imported hardwoods with similar performance; Pacific Jarrah (Manilkara) offers a slightly different grain and colour as an alternative to Merbau's classic reddish-brown tone.

What's the Reeded profile used for?

Reeded boards have a grooved surface texture for extra grip and a different visual finish compared to smooth-faced decking.

Do I need to oil this decking before or after installation?

We recommend oiling within the first few weeks of installation to lock in the colour and reduce tannin bleed during early rain exposure, then re-coating periodically to maintain the finish.

How much decking do I need for my project?

Measure your deck area and add roughly 5-10% for wastage and cuts — get in touch if you'd like help estimating quantities.
