Grain Pattern

Mostly straight to gently interlocked, with prominent cathedral/chevron figure consistent with flat-sawn or book-matched boards; coarse texture and small knots.

Color & Appearance

Golden honey-brown to medium brown heartwood with darker streaking; little visible sapwood. Teak typically develops a deeper brown-gray patina outdoors and has moderate natural luster.

Hardness (Janka)

1,070 lbf Janka — Medium; values vary by origin and age.

Durability & Decay Resistance

Very Durable; strong resistance to decay, moisture, and insects, especially in heartwood.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$12–30 per board foot for ordinary surfaced teak; premium old-growth or wide clear stock may exceed this.

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

Wood Age Estimate
The board appears weathered and previously installed, but visible surface wear cannot reliably establish its calendar age; likely years to decades old.

Common Uses

Exterior joinery, doors, decking, furniture, boatbuilding, cabinetry, flooring, and architectural trim.

Geographic Origin

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

Workability

Machines and sands reasonably well, though silica and natural oils can dull tools and complicate gluing; predrilling is advisable.

Finish Recommendations

Clean and sand evenly; use a teak-compatible exterior oil for color retention or marine varnish/polyurethane after thorough degreasing. Leaving it unfinished permits silver-gray weathering.

Notable Features

Naturally oily, dimensionally stable, coarse-textured, and often faintly aromatic; dark pin knots and weathered margins are visible.
