Merbau
Intsia bijuga
Imported HardwoodSoutheast Asia, Papua New Guinea, Pacific Islands, North Queensland
Also known as: Kwila, Ipil, Johnstone River Teak
Appearance
Merbau heartwood is yellow-brown to orange-brown when freshly cut, darkening to a rich reddish-brown with age. The grain is typically interlocked or wavy, producing a ribbon figure on radial surfaces. The texture is coarse but even, and freshly cut timber has a characteristic oily scent.
Workability
Merbau dries well with minimal shrinkage. It finishes effectively with paint, stain, and polish, and responds well to hand and machine tools. Be aware of potential gum bleed which can stain surrounding surfaces — particularly on new decking installations during the first few months.
