Rot Resistance: 
Cumaru has excellent durability and weathering properties. The wood is rated as very durable regarding decay resistance, though it may be susceptible to some insect attacks.

Working Qualities:
Tends to be difficult to work on account of its density and interlocked grain. If the grain is not too interlocked, Cumaru can be surface-planed to a smooth finish. However, the wood contains silica and will have a moderate blunting effect on tool cutters. Due to its high oil content and density, Cumaru can present difficulties in gluing, and pre-boring is necessary when screwing or nailing the wood.
