How to Select Cumaru Decking Material that is Right for You
Navigating your options for decking materials can at times be an overwhelming feat, especially when
you have limited knowledge on wood types that are suitable for outdoor installations. With an ever-
expanding market for wood decking choices, certain wood types stand out. Like Ipe wood decking,
Cumaru is gaining popularity because of its long-lasting strength, extreme durability, and innate
beauty—all at affordable price points. Cumaru is a highly sustainable wood source derived from a
high-density species of hardwood that commonly occurs in northern areas of South America.
Cumaru is notable for its varied appearance and unique graining. Often called “Brazilian Teak,”
Cumaru closely resembles teak. This makes it suitable for a variety of interior and outdoor uses,
ranging from decking to indoor/outdoor furniture, gazebos, pergolas, boardwalks, and so much more.
Known for its longevity, Cumaru lumber is also notable for its high resistance to insects and decay.
Thanks to its remarkable strength and toughness, Cumaru makes for an exceptional decking choice
across different settings, ranging from residential applications to commercial settings, boardwalks,
and even public decks.
When choosing Cumaru decking materials, it is critical that you know your options. This hardwood
can range in color from reddish and yellowy browns to nearly purplish cordovan colors. While its
coarse graining resembles that of red oak, its exotic color range makes Cumaru a more versatile
choice. Its grain variations also add drama and beauty to any deck installation. This exceptional
variation also means that no two pieces of Cumaru wood will ever have the exact same appearance,
thus reflecting the untamed beauty of the exotic hardwood. Cumaru likewise reflects somewhat of a
tropical character with its color and striping variation. Natural weathering also leads to the
development of a silvery gray patina as time goes.
Your Cumaru deck will last an exceptionally long time and it can get better with age, with the right
maintenance. Known for strength and durability, Cumaru may perform or behave differently under
various (extreme) weather conditions. When choosing this decking option, make sure that you
protect it with the right finish. Left unfinished, you allow the wood to be acclimated on site, but if
you live or are building in an area where extreme sunlight can be an issue, a UV inhibiting finish is
advisable. A low maintenance option where you let the wood fade before refinishing is also possible.
This gives Cumaru wood a silvery gray finish over time.
