Brushbox is an Australian species of hardwood that goes by the botanical name of Lophostemon confertus. Brush Box is a
medium to large tree, attaining a height of 35 – 40m and grows in Australia and Indonesia. It has a Janka rating of
2135 on the hardness scale.
Brushbox sapwood is pale grey–brown. The heartwood sometimes has reddish or pink tones with the brown. But there is
considerable color variation from tree to tree. Over time, brushbox encounters a color change with exposure to sunlight when
the color starts assuming reddish tones.
Brushbox hardwood has a naturally glossy appearance with a close, even texture, with the grain often being curly and
interlocking. Because of its hardness, the wood is difficult to saw and nail. For nailing, pre–boring is recommended.
Like most Australian hardwoods, Brushbox is durable and strong enough to be suitable for a variety of building products
including flooring. Brushbox hardwood floors have over twice the hardness of teak, 47% harder than hard maple, 24% harder
than African padauk and just over 17% harder than pecan or hickory. It falls just short of Santos Mahogany’s 2200 on the
Janka hardness scale.
Drying the brush box wood is a slow process that should be carefully monitored to prevent warping and damage which is
inevitable if this is rushed. Brushbox hardwood floor are highly termite resistant and have no odor.
