Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to wavy grain; typically very coarse and uneven texture with a dull surface luster due to high oil content.
Color Description
Heartwood is typically golden or medium brown, darkening with age. Sapwood is pale yellowish-white. This sample shows a weathered silvery-gray patina typical of unfinished teak exposed to UV rays and rain.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptionally resistant to rot, decay, and termites due to high natural oil and rubber content.
Common Uses
Outdoor furniture, boat building (especially decking), exterior joinery, flooring, and veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Approximately $25.00 - $45.00 per board foot depending on source and grade.
Wood Age Estimate
5 to 10 years of outdoor exposure; the deep graying and slight surface checking indicate significant weathering and oxidation.
Sustainability Status
Vulnerable (IUCN Red List); plantation-grown wood is widely available with FSC certification, but old-growth Burmese teak is heavily restricted and CITES listed in certain regions.
Workability
Generally easy to work but high silica content causes severe blunting of tool edges. Glues well only after surface oils are wiped with a solvent like acetone.
Notable Features
Distinctive leather-like scent when freshly cut; oily feel to the touch; exceptional dimensional stability and weather resistance.
Finish Recommendations
Teak oil or tung oil to restore color; can be left unfinished to maintain the silver patina. Requires thorough cleaning/sanding before application.
Identification Confidence
High; the combination of outdoor furniture application, coarse texture, and the specific silvery oxidation pattern is characteristic of weathered Teak.
