Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly wavy grain with a coarse, uneven texture. Occasional interlocked grain and a distinct oily feel.
Color Description
Heartwood starts a golden or medium brown and darkens with age; sapwood is pale yellowish-white. This sample shows weathering with a matte, silver-brown patina and visible oxidation from outdoor exposure.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable. Highly resistant to rot, fungi, and termites due to high natural oil and rubber content.
Common Uses
Outdoor furniture, boat building (especially decks), exterior construction, veneer, and high-end cabinetry.
Geographic Origin
Native to South and Southeast 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 FEQ (First European Quality) lumber.
Wood Age Estimate
Approximately 20-50 years based on the deep oxidation, surface check marks, and silvering of the grain indicative of long-term outdoor exposure.
Sustainability Status
IUCN status: Endangered (for wild populations). Burmese teak is heavily restricted (CITES-like sanctions); FSC-certified plantation teak is preferred.
Workability
Generally easy to work but contains high silica content which dulls steel tools quickly. Glue can be difficult due to natural oils; surface wiping with solvent is required.
Notable Features
Distinctive leather-like scent when freshly cut. High oil and rubber content make it naturally water-resistant and grippy even when wet.
Finish Recommendations
Teak oil or tung oil to maintain color; alternatively, left unfinished to gray naturally. For film finishes, dewaxed shellac is needed as a sealer.
Identification Confidence
High. The characteristic coarse grain, visible 'oily' sheen despite weathering, and specific checking pattern on the radial surface are hallmark indicators of Tectona grandis.
