AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- The grey patina and surface checking suggest the wood has been exposed to the elements for 2 to 5 years.
Common Uses
Outdoor furniture, decking, boat building, flooring, cabinetry, and heavy construction.
Geographic Origin
Tropical Africa (West and East Africa)
Workability
Generally good, though interlocked grain can cause tearout during planing. High silica content can dull blades quickly. Glues and finishes well once surface oils are cleaned.
Finish Recommendations
Penetrating oils or teak oils are recommended for maintenance. If the silver-grey look is desired, it can be left unfinished. Sanding is required to restore original golden tones.
Notable Features
Often referred to as "African Teak." Known for high oil content and exceptional stability in humid environments. Dust can be a potent sensitizer/irritant.
