About Cumaru

Cumaru, often marketed as "Brazilian Teak," is one of the best-value exotic hardwoods available. With a Janka hardness of 3,330 lbf — nearly as hard as Ipe — Cumaru delivers outstanding durability and natural decay resistance at a significantly lower price point. Its warm golden-brown to reddish-brown color and pleasant vanilla-like aroma (when freshly cut) make it a beautiful and practical choice for decking, flooring, and outdoor construction. Cumaru's natural oils provide excellent weather resistance without chemical treatment, and it carries a Class A fire rating similar to Ipe.
