DRYING

Merbau wood can be dried satisfactorily without incurring significant defect.

   
Air Seasoning Seasoning of 2.5 cm thick I. palembanica boards up to air-dry condition and humidity 15% takes 82 days respectively.
Kiln Drying Recommended drying temperature and relative humidity are 43-71C and 83-38%.
   
WORKING PROPERTIES

Sawing/Machining; Sawing is difficult as wood clogs saw teeth and dulls cutting edges; carbide tooling recommended. Sanding: Sands satisfactorily.
Nailing: Good holding ability.
Finishing: Wood stains black in contact with ferrous metals or moisture.
