Cumaru Lumber

Cumaru, also known as Brazilian Teak, is one of the hardest and most durable South American hardwoods, with deep golden-brown to reddish tones that grow richer over time. Naturally resistant to insects, decay, and heavy wear, it’s perfect for decking, flooring, and architectural millwork. Indoors, Cumaru adds elegance to cabinets and furniture while lasting a lifetime. Its density makes it challenging but rewarding to work. Compare with Ipe Lumber or Purpleheart Lumber for other dense exotics.
