Natural durability: Maçaranduba wood is resistant to attack by rotting fungi and subterranean termites. It presents moderate resistance to wood-dry termites and low resistance to marine xylophages. The specie was described as very resistant to fungus and termite attack, but susceptible to marine pin hole, was considered highly durable in contact with the soil, presenting a useful life of over 8 years.
Treatability: the heartwood is impermeable to water-soluble preservative solutions (CCA-A), even under pressure treatment.
Workability: Maçaranduba wood is moderately difficult to cut and flatten, but is easy to turn and glue. It tends to crack if nailed or screwed without previous drilling. It receives good finish, paint and varnish.
Drying: Air-drying is difficult, presenting cracks, warping and severe hardening. Drying in oven should be slow and carefully controlled.
