Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Typically straight grain, occasionally wavy or interlocked; coarse, uneven texture with a dull surface luster and an oily feel. Displays some cathedral patterns in flat-sawn sections and visible growth rings.
Color Description
Heartwood starts as a golden or medium brown, darkening with age. Due to outdoor exposure, this sample has weathered to a silvery-gray patina with dark streaks of surface mold/mildew typical of untreated teak.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; renowned for exceptional decay resistance, high silica content, and natural oils that provide termite and moisture resistance indoors and outdoors.
Common Uses
Outdoor furniture, boat building (especially decks), flooring, paneling, and high-end cabinetry.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in tropical regions across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot for high-quality Burmese teak; plantation-grown varieties are slightly less.
Wood Age Estimate
Outdoor exposure of 5–10 years. Extensive silvery-gray weathering and surface checking suggest at least several seasons of UV and rain exposure.
Sustainability Status
Listed on the IUCN Red List as Endangered due to a population decline of over 50% in native habitats. FSC-certified plantation teak is commonly available and more sustainable.
Workability
Generally easy to work but contains high silica, which rapidly dulls cutting edges. Glues well only on freshly surfaced areas due to high oil content. Finishes well with oils but can be difficult for lacquers to adhere.
Notable Features
Characteristic leather-like scent when freshly cut. High natural oil content makes it unique for barefoot comfort on decks. Dust can cause skin and respiratory irritation.
Finish Recommendations
Teak oil or penetrating sealers are recommended to maintain the golden-brown color. If the gray patina is desired, it can be left unfinished but should be cleaned periodically with a mild detergent.
Identification Confidence
High. The weathering pattern into a silvery-gray color, the coarse grain texture, and its application as a heavy outdoor tabletop are definitive characteristics of Tectona grandis.
