A hard and very durable timber with rich reddish-brown color tones, typical uses include heavy construction, general joinery,  boatbuilding and other marine applications. The warm colors and high density make for excellent T&G flooring. Gum veins are common and give natural character.

A large tree producing a light to dark red timber darkening to a uniform red-brown mahogany color. It can have a straight or interlocked grain with an even medium coarse texture.

We do not recommend acrylic coating with Jarrah. Water based coating can change the color from rich redish-brown to a dark orange; a solvent may change the color from natural rich reddish-brown to light reddish/orangy- brown. We only recommend an oil stain, that keeps the natural deep reddish-brown color of Jarrah.
