Défauts dus au séchage
Ease of Drying: In Malaysia surian timber is reported to dry rapidly. Boards 25 mm thick take 1 to 3.5 months to air dry. Drying Defects: Slight warping is reported. Kiln Schedules: Boards 25 mm thick can be kiln dried from 50% to 10% moisture content in 3 to 6 days without any degrade.

OUVRABILITÉ
Sciage
Sawing of this species is reported to be rather easy.
Coupe de placage de déroulage
The timber peels readily to smooth, tight veneer of uniform thickness.
Placage tranche
The timber peels readily to smooth, tight veneer of uniform thickness.
Effet d'émoussement
It is considered to have a slight blunting effect on the cutting elements. Occasional white deposits tend to chip the cutting edges.
Usinage
Machining is considered as easy, but results in a woolly surface.
Rabotage
It often exhibits a woolly finish after planing but this can be alleviated by reducing the cutting angle to 20 degrees.
Perçage
Boring is reported to be difficult.
Clouage
It nails moderately well, but screw and nail-holding characteristics are sometimes poor.
Collage
Gluing behavior is reportedly good.
Finissage
It is easy to finish.
Teinture
It is easy to stain.
Polissage
Polishing of this wood is easy.
Cintrage à la vapeur
This species is difficult to bend.
