The timber seasons slowly with medium shrinkage rates between 3 to 6 %, but once dry works fairly well, although some silica is often present and may blunt some tools. There is a distinct odour of camphor when freshly sawn or worked, however the timber is not a true camphor and is not moth repellent

The heartwood is a uniform yellowish, pinkish or deep reddish brown with the sapwood yellow-brown or pinkish, easy to distinguish and is lyctid borer susceptible. The texture is medium to coarse and very even and finishes cleanly, but if the timber is wet the wood will

blacken when worked with iron tools or coated with ferrous based products.

In Malaysia and Indonesia, Kapur is used as general construction timber, as well as for both internal and external finishing materials particularly exposed beams, door and window joinery, staircase material and furniture.

In Australia large quantities have been imported and used for similar applications over the years with the timber highly prized for external joinery and in particular door and window

sills and more recently decking, as the timber in a non-ground contact situation exhibits a Durability Class 2 characteristic.
