AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Matured lumber sample; shows signs of surface weathering, oxidation, and fine surface checking consistent with several years of outdoor exposure or stored lumber.
Common Uses
Outdoor decking, boardwalks, heavy marine construction, docks, outdoor furniture, flooring, and architectural cladding.
Geographic Origin
Central and South America (principally Brazil, Bolivia, and Peru).
Workability
Difficult to work due to extreme density and blunting effect on cutting tools. Pre-drilling required for fasteners; glues with moderate difficulty due to high density and natural oils.
Finish Recommendations
Penetrating oil finishes with UV inhibitors formulated specifically for dense exotic hardwoods; avoid thick film-forming finishes like varnish which tend to peel.
Notable Features
Contains lapachol powder in wood pores which can cause skin irritation/sensitization; naturally fire-resistant (Class A fire rating); extremely heavy and dense (sinks in water).
