Popular hardwoods include Blackbutt, Jarrah, Merbau and Spotted Gum. All are highly resilient, extremely durable, and have a natural fire resistance, so they are safe in bushfire-prone areas or for use under an outdoor kitchen or barbecue. Blackbutt is pale brown in colour, Jarrah is rich brown, Merbau warm red-brown and Spotted Gum can range from light browns through to deep red-brown hues. However, you can change the colour of your deck by staining it or oiling it, which will also help protect it from UV rays. Maintenance is as simple as washing it regularly with a bristle brush and a suitable cleaning agent.
