Value & Age

Estimated Market ValueNot an official valuation

Approximately US$15–35 per board foot for ordinary kiln-dried stock; premium old-growth or clear material can 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 single finished face; it appears relatively clean and recently worked, without clearly diagnostic patina.

Common Uses

Outdoor furniture, decking, boatbuilding, flooring, cabinetry, architectural joinery, and turned objects.

Geographic Origin

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

Workability

Cuts and sands reasonably well, but its silica and natural oils can dull tools and complicate gluing; wipe surfaces with solvent and use fresh, sharp cutters.

Finish Recommendations

Leave unfinished for weathered silvering, or use teak oil, exterior oil, varnish, or polyurethane after thorough surface cleaning and preparation.

Notable Features

Distinctive oily feel, moderate weight, excellent dimensional stability, and characteristic teak aroma when freshly cut.
