Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly wavy with a coarse, uneven texture and a naturally oily feel. Presence of dark brown or black mineral streaks and standard flat-sawn cathedral patterns.
Color Description
Heartwood is typically a golden or medium brown that darkens with age. Sapwood is a pale yellowish-white. It exhibits a dull luster and can develop a silver-gray patina if left outdoors untreated.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable. Highly resistant to rot, fungi, and termites due to its high natural oil and silica content. Excellent weathering characteristics.
Common Uses
Marine construction (boat decks and trim), outdoor furniture, high-end cabinetry, veneer, exterior joinery, and flooring.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown in plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot depending on source (FEQ - First European Quality) and grain quality.
Wood Age Estimate
Modern sample, likely less than 5-10 years old; appears to be kiln-dried stock with minimal oxidation or patina development.
Sustainability Status
IUCN Red List: Endangered (wild populations); widely available via FSC-certified plantations. CITES: Not listed.
Workability
Generally easy to work but contains silica which can dull cutting edges rapidly. Glues well following a surface wipe with solvent (to remove oils) and finishes nicely, though its oils can retard drying of some oil-based finishes.
Notable Features
Distinctive leather-like scent when freshly cut. High natural oil content makes it unique for moisture resistance. Silica content contributes to its renowned slip-resistance.
Finish Recommendations
Teak oil or Danish oil to maintain color; clear epoxies for marine use; or left unfinished for a natural silver-gray weathered look.
Identification Confidence
High. The golden-brown hue, characteristic dark streaks, visible vessel lines (coarse texture), and the specific way the grain reflects light are diagnostic of Tectona grandis.
