Grain Pattern

Generally straight to slightly wavy grain, with coarse texture and faint interlocked areas; no distinctive figure is visible. The image appears to show a flat-sawn, weathered face rather than end grain.

Color & Appearance

Aged medium brown to gray-brown surface with subdued luster and possible darker streaking; fresh teak heartwood is golden to medium brown and typically darkens, then silvers outdoors.

Hardness (Janka)

Approximately 1,070 lbf Janka — Medium.

Durability & Decay Resistance

Very Durable; heartwood has strong resistance to decay, insects, and weathering.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $15–$35 per board foot for ordinary dry stock; premium clear or plantation material may cost more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Not reliably estimable from this photograph; gray patina and surface wear suggest prolonged exposure or aging, not necessarily old wood.

Common Uses

Outdoor furniture, decking, boatbuilding, architectural trim, flooring, cabinetry, and turned goods.

Geographic Origin

Native to South and Southeast Asia; widely plantation-grown in Indonesia, India, Myanmar, Thailand, and parts of Africa and Latin America.

Workability

Machines and sands reasonably well, though silica and natural oils can dull tools; predrilling is advisable, and gluing may require freshly prepared surfaces and careful adhesive selection.

Finish Recommendations

Clean and sand thoroughly; use penetrating teak oil for color retention or exterior-rated film finishes with careful maintenance. Unfinished outdoor exposure produces gray silvering.

Notable Features

Naturally oily, stable, coarse-textured wood with characteristic leather-like or resinous scent when freshly cut; often develops an attractive silver-gray outdoor patina.
