Cumaru Decking: Built for Strength, Value & Long-Term Performance
The Cumaru 1×6 Decking Board (Solid) (actual ¾″ × 5½″) offers the rugged durability and dense, high-performance structure Cumaru is known for. Often called Ipe’s little brother, Cumaru shares many of the same advantages—rot resistance, insect resistance, and excellent outdoor longevity—while providing a more cost-efficient path to premium Brazilian hardwood construction. This solid (non-grooved) profile is suitable for 12″ or 16″ joist spacing and pairs perfectly with installation methods such as face-screwing, the Pro Plug System, the CAMO Edge fastening method, and the DeckMaster Undermount system for a clean finish and long-term stability.
Premium Cumaru Color & Natural Slip Resistance
Cumaru displays a distinctive red-gold palette with occasional brown undertones, giving every deck a warm, dynamic appearance. Its interlocked grain and naturally textured surface provide excellent slip resistance, making it ideal for residential decks, boardwalks, walkways, and high-traffic commercial spaces. Many boards show rich character and variation—one of the defining aesthetic benefits of Cumaru hardwood.
Durability Backed by Real-World Performance
Cumaru is exceptionally dense, delivering outstanding weather resistance and long-term value. Used in South America for generations in fence posts and ground-contact timbers known to last nearly a century, Cumaru excels in demanding climates with heavy rainfall, intense sunlight, or coastal conditions. When installed correctly, Cumaru decking routinely provides decades of reliable service with minimal upkeep.

Sustainability & Responsible Sourcing
Cumaru is selectively harvested under strict forestry management practices that prioritize long-term forest health. By sourcing from operations aligned with sustainable guidelines, Brazilian Wood Depot helps ensure that tropical forests maintain their ecological value rather than being converted for agriculture or other high-impact uses.
