Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Usually straight, though occasionally wavy or interlocked. The texture is coarse and uneven with a distinct oily or greasy feel.
Color Description
Heartwood is a golden or medium brown, darkening with age. Weathered samples like this one develop a signature silver-gray patina due to UV exposure and leaching of surface oils.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Highly resistant to rot, termites, and fungal decay. Excellent weathering properties for outdoor use.
Common Uses
Outdoor furniture, boat building (especially decks), flooring, veneer, and exterior joinery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot (Premium pricing due to demand and import restrictions).
Wood Age Estimate
5 to 10 years of outdoor exposure; the significant 'silvering' or graying and surface grain raising indicate several seasons of sun and rain without recent oil treatment.
Sustainability Status
IUCN Red List: Endangered (wild populations). However, it is widely available from FSC-certified plantations.
Workability
Generally easy to work, though high silica content can dull cutting edges rapidly. High oil content can make gluing and finishing difficult without proper surface preparation (wiping with solvent).
Notable Features
Distinctive leather-like scent when freshly cut. Heavy natural oils make it uniquely water-resistant and stable.
Finish Recommendations
Teak oil or tung oil to restore color. Can be left unfinished to maintain silver patina. Avoid film-building finishes like thick polyurethane which may peel due to natural oils.
Identification Confidence
High; the slat construction, typical outdoor weathering patina (silver-gray), and coarse visible grain are classic indicators of Teak garden furniture.
