Pacific Jarrah

PACIFIC JARRAH Sapotaceae

These trees have a narrow band of sapwood, between 30 and 50mm wide, which is whitish to pale brown. The heartwood ranges in colour from a light red when freshly cut to a dark reddish-brown when dry.

Pacific Jarrah is available in most sizes and good lengths.

The timber is exceptionally hard, heavy, strong and tough. It must be dried slowly and with care to minimise down grade. Moderatly difficult to work, but finishes smoothly. Pre-boring is necessary for nailing and screwing

The timber is very stable once kiln dried and is extremely resistant to moisture absorbsion.

It will take both natural finishes and paints well.
