Grain Pattern

Straight to wavy grain with a somewhat coarse texture, showing distinct growth rings visible on the end grain.

Color & Appearance

Golden to medium brown, darkening with age, featuring natural oils that give it a slightly waxy feel and good luster.

Hardness (Janka)

1,070 lbf (Medium)

Durability & Decay Resistance

Very Durable, with exceptional resistance to rot, decay, and insect attack due to natural oils.

Value & Sustainability

Estimated Market Value
$15.00 to $30.00+ per board foot depending on grade and origin.
Wood Age Estimate
Estimated to be several decades old based on oxidation, surface dust, and patina.
Sustainability Status
Generally of least concern if harvested from plantations (such as FSC-certified sources in Central/South America or Asia); wild-harvested old growth from certain regions faces trade restrictions.

Common Uses

Boat building, yacht decking, exterior furniture, carving, indoor flooring, and fine cabinetry.

Geographic Origin

South and Southeast Asia, primarily Myanmar, India, Laos, and Thailand; widely planted in tropical regions globally.

Workability

Generally easy to work with both hand and machine tools, though its high silica content can dull cutting edges quickly. Glues and finishes well despite natural oils.

Finish Recommendations

Teak oil or penetrating finishes are traditional. Surface preparation requires wiping down natural oils with a solvent before applying varnishes or glues.

Notable Features

Contains natural teak oil that imparts a leathery scent when fresh, excellent dimensional stability, and high resistance to moisture and weathering.
