Défauts dus au séchage
Ease of Drying: Drying is slow and rather difficult. Boards of 15 mm thick take about 3 months to air dry. Drying Defects: Resin exudation is reported to be common, especially when drying at high temperatures. It is prone to cupping, bowing, springing and end checking. Usually there is little splitting, surface checking, staining and insect attack during drying. Kiln Schedules: Schedule proposed for Apitong.
