Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly interlocked grain with a coarse, uneven texture and visible long vessel streaks
Color Description
Golden to medium brown heartwood that darkens with age; sapwood is pale yellowish white. Features a natural dull luster and oily feel
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and weathering due to high natural oil content
Common Uses
Boat building (decks and trim), outdoor furniture, high-end flooring, veneer, and exterior joinery
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations globally
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on source and grade
Wood Age Estimate
Relatively fresh milled stock (less than 1 year) based on the bright golden hue and lack of silver-gray weathering
Sustainability Status
IUCN Red List: Endangered (Wild populations). Not CITES listed but widespread availability of plantation-grown FSC certified stock
Workability
Generally easy to work but high silica content causes rapid dulling of cutting edges. Glues well if surfaces are wiped with solvent to remove natural oils
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil and rubber content; feels greasy to the touch
Finish Recommendations
Teak oil or tung oil to replenish natural resins; lacquer and varnish can be problematic due to oil interference unless dewaxed shellac is used as a sealer
Identification Confidence
High; the combination of large open pores, golden-brown color, and characteristic oily texture is diagnostic of Tectona grandis
