AKA Brazilian Teak
Cumaru is a South American hardwood that is excellent for decking. Its extremely hard, rot resistant and one can expect at least a 25 year lifespan when used for your deck. Cumaru lumber is similar to Ipe in color but has a slightly coarser grain to it. Since it is primarily used for decking it is supplied as a surfaced on 4 sides and eased edge (S4S, E4E) product that can be grooved for hidden fasteners if desired. The standard decking sizes are 1×4 and 1×6 though it should be noted that Cumaru is sold in slightly thicker, true 1″ or 5/4 thickness to provide greater stability. Rough sawn lumber and larger timbers are also available but only on a special order basis.
