Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to slightly wavy; narrow grain lines suggests a tropical growth pattern with regular seasonal cycles. Shows typical flat-sawn cathedral patterns in some areas.
Color Description
Heartwood is a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It has a dull to medium luster and an oily feel.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, fungal decay, and termites due to high natural oil content.
Common Uses
Boat building (decks, trim), outdoor furniture, flooring, veneer, cabinetry, and exterior construction.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for high-quality Burmese Teak; Plantation Teak is lower at $15.00 - $25.00.
Wood Age Estimate
Recently processed or refinished. The lack of significant graying (patina) suggests it has been protected from UV or is a newer production.
Sustainability Status
Natural-grown Teak from Myanmar is under trade restrictions; Plantation-grown is widely available and FSC certified.
Workability
Generally easy to work but high silica content will dull tools quickly. Glues and finishes can be difficult due to natural oils; surface wiping with solvent is recommended before bonding.
Notable Features
Distinctive leather-like scent when freshly cut. Naturally high oil content makes it uniquely resistant to moisture and water damage.
Finish Recommendations
Teak oil or tung oil to maintain the natural look; if film-finishing, specialized primers or dewaxed shellac are needed to prevent adhesion failure.
Identification Confidence
High; the golden-brown hue, tight linear grain with darker streaks, and the characteristic oily surface sheen are hallmark traits of Tectona grandis.
