Cumaru, also known as "Brazilian teak", is an exotic hardwood that naturally resists rot, decay and insect attack. Cumaru is the second hardest decking wood as well. Cumaru has a 50+ year lifespan without preservatives. Cumaru has many benefits over genuine teak. Cumaru works especially well with face screws or a plug system.
