Common Uses
Exterior joinery, boat building, flooring, furniture, cabinetry, decking, and heavy construction.
Geographic Origin
Tropical Africa (West and East Coast regions)
Workability
Generally works well, though interlocked grain can cause tear-out during surfacing. Contains calcium carbonate deposits which can dull cutting edges quickly.
Finish Recommendations
Takes stains and finishes well; however, due to natural oils, a solvent-based sealer or wiping with acetone is recommended before applying polyurethane or lacquers.
Notable Features
Often lacks a distinct odor when dry; dust can be a potent sensitizer causing respiratory issues or skin irritation. Known for its high strength-to-weight ratio.
