Question 1

What makes Merbau decking popular for outdoor decks?

Accepted Answer

Merbau is a hardwood decking timber known for its rich reddish-brown colour, attractive grain pattern, and high durability outdoors, making it well suited to Australian climates.

Question 2

Is Merbau a hardwood or softwood?

Accepted Answer

Merbau is classified as a hardwood, meaning it is dense, strong, and generally more durable than most softwood decking options.

Question 3

How long can Merbau decking last?

Accepted Answer

With proper installation and maintenance, Merbau decking can last 25–40 years or more above ground due to its natural resistance to decay and termites.

Question 4

Does Merbau decking resist rot and insects?

Accepted Answer

Yes. Merbau contains natural oils and compounds that provide resistance to rot, decay, and many wood-boring insects, including termites.

Question 5

How does Merbau decking handle weather and sun exposure?

Accepted Answer

Merbau is weather resistant and performs well under sun, rain, and varying Australian conditions when installed with proper ventilation and drainage.

Question 6

Why do Merbau decking boards change colour over time?

Accepted Answer

When left untreated, Merbau naturally weathers to a silver-grey patina. Regular oiling or sealing helps maintain its original warm reddish-brown colour.

Question 7

What maintenance does Merbau decking require?

Accepted Answer

Maintenance typically involves routine cleaning and periodic oiling or sealing to protect against UV exposure and preserve the timber’s colour.

Question 8

Can Merbau decking stain nearby surfaces?

Accepted Answer

Yes. Merbau contains tannins that can leach when wet and may stain nearby concrete, stone, or tiles if not managed during installation.

Question 9

Is Merbau decking suitable for coastal areas?

Accepted Answer

Yes. Merbau’s density and moisture resistance make it suitable for coastal environments, though corrosion-resistant fixings are recommended.

Question 10

Can Merbau decking be used in bushfire-prone zones?

Accepted Answer

Merbau can meet certain Bushfire Attack Level (BAL) requirements, such as BAL 29, when specified and installed in accordance with regulations.

Question 11

How should I fasten Merbau decking boards?

Accepted Answer

Due to its density, Merbau decking should be pre-drilled and fixed using stainless steel or corrosion-resistant screws to prevent splitting and staining.

Question 12

Does Merbau decking require specialised tools to cut?

Accepted Answer

Merbau can be cut with standard woodworking tools, although its hardness may cause blades to dull faster than when working with softer timbers.

Question 13

Is Merbau decking environmentally sustainable?

Accepted Answer

Merbau’s sustainability depends on responsible sourcing. Choosing FSC-certified or ethically sourced timber supports sustainable forestry practices.

Question 14

Will Merbau decking resist heavy foot traffic?
