Common Uses
Heavy construction, exterior decking, flooring, furniture, joinery, and turning.
Geographic Origin
Southwest of Western Australia
Workability
Difficult to work due to extreme hardness and interlocked grain which can cause tearout during planing. Pre-drilling is required for nailing and screwing.
Finish Recommendations
Takes oils, varnishes, and marine-grade polyurethane exceptionally well after proper surface preparation and sanding.
Notable Features
High density, rich natural pigmentation, excellent dimensional stability once dry, and high natural oil content.
