What is Merbau and why is it used for outdoor picnic tables?

Merbau (Intsia bijuga / Intsia palembanica) is a tropical hardwood from Southeast Asia and the Pacific that is widely used for outdoor furniture and decking in Australia. It carries an AS 5604 Durability Class 2 above-ground rating, a Janka hardness of approximately 8.6 kN, and contains natural oils that repel moisture and resist fungal decay. Its chocolate-brown colour with golden interlocked grain is highly regarded for its visual warmth -- making it a popular choice for hospitality and lifestyle-focused installations.

How does Merbau compare to Ironbark and Spotted Gum for picnic tables?

Merbau sits below Ironbark (14 kN Janka, Class 1) and Spotted Gum (11 kN Janka, Class 1) in terms of hardness and durability rating, but it outperforms both on dimensional stability -- Merbau has very low shrinkage and movement coefficients, making it less prone to surface checking in dry climates. It is also slightly lighter than Ironbark, making assembly and transport easier. For a 25 to 30-year service life in above-ground applications, Merbau is a cost-effective and aesthetically distinctive choice.

Does Merbau bleed or stain surrounding surfaces?

Freshly milled Merbau contains water-soluble tannins that can leach as a reddish-brown liquid in the first few rain events after installation. This is a normal characteristic of the species and diminishes significantly within 3 to 6 months as the tannins exhaust. Auscraft recommends applying a penetrating oil finish before delivery and placing Merbau tables on surfaces where initial tannin bleed can be tolerated -- concrete, pavers or bare soil. Avoid installation on light-coloured decking or premium stone within the first season.

Where Merbau Picnic Tables Work Best

Merbau's AS 5604 Class 2 durability rating and warm colour make it the preferred choice for settings where visual appeal is a priority alongside practical outdoor performance.

Residential Gardens and Backyards

Homeowners frequently choose merbau for backyard picnic tables because the reddish-brown tone complements Australian garden landscaping, timber decking and brick or sandstone paving. Merbau ages gracefully — it weathers to a darker brown and eventually silver-grey if left unoiled, or holds its warm reddish tone with annual oiling. For a residential setting without the commercial maintenance demands, merbau provides excellent value and a premium aesthetic.

Cafes, Restaurants and Bar Courtyards

Hospitality venues consistently choose merbau for outdoor seating areas where the furniture needs to contribute to atmosphere, not just function. The warm colour pairs well with both modern industrial and traditional pub aesthetics. Merbau tables can be specified with smooth-sanded, oiled finishes that are ready for immediate hospitality use. Auscraft builds to custom dimensions to fit specific courtyard layouts and table-to-seat ratios.

Wedding Venues and Event Spaces

Wedding venues and function facilities require outdoor furniture that photographs well and creates a cohesive setting for events. Merbau's natural lustre and warm tones make it one of the most photographed timber species in outdoor event settings. Custom lengths from 1800mm to 3000mm allow event-style placement for long communal tables.

Boutique Hotels and Glamping

Boutique accommodation operators — glamping sites, eco retreats, luxury holiday parks — specify merbau for outdoor dining and relaxation areas where design quality signals the brand's positioning. Merbau's appearance justifies a premium to guests in a way that pine or generic hardwood alternatives cannot.

Merbau Maintenance Guide

Merbau requires modest maintenance to retain its colour and extend its service life. Key care steps:

Before installation: Apply a penetrating hardwood oil (such as Feast Watson Decking Oil) to all surfaces. Merbau's tannins can produce reddish runoff on initial exposure to rain — allow the first coat to cure before placing on sealed surfaces.
Annual oiling: Clean the table surface and apply one coat of hardwood oil per year. This preserves the reddish-brown colour and protects against surface drying and cracking.
Colour note: If left unoiled, merbau weathers progressively to silver-grey over 3 to 5 years — a natural process that does not affect structural integrity but changes appearance significantly.
Tannin staining: New merbau can bleed reddish-brown tannin in rain runoff. Position the table where initial runoff will not stain paving or concrete, or pre-seal the surface before installation.

Merbau vs Spotted Gum and Ironbark

Choosing between merbau, spotted gum and ironbark depends on your priorities:

Merbau (8.6 kN, Class 2, 25–40 yr) — warm reddish-brown colour, best for residential, hospitality and design-led projects. Requires annual oiling for colour retention. Most aesthetic of the three species.
Spotted Gum (11.0 kN, Class 1, 40+ yr) — golden-tan colour with natural figuring. Harder and longer-lasting than merbau. Good mid-point between aesthetics and commercial durability. See Spotted Gum picnic tables.
Ironbark (14.0 kN, Class 1, 40+ yr) — maximum hardness and longevity. Dark grey-brown, weathers to silver-grey. Best for councils, schools and high-traffic commercial. See Ironbark picnic tables.
