What is Cumaru?

Cumaru is a high density hardwood species that grows throughout the northern portions of South America. The scientific name for Cumaru is Dipteryx odorata. Cumaru is also known as Tonka, Tonka bean and also "Brazilian Teak" due to its beautiful graining and varied appearance. Cumaru is very resistant to decay and insects and is an ideal material for exterior usage as decking, outdoor furniture, pergolas, gazebos, boardwalks and more.

Cumaru decking is quickly becoming a highly sought after species of wood decking.  Cumaru decking's long lasting strength, durability and beauty combined with it's affordable pricing combine to make Cumaru decking a real winner as a decking material. Pronounced "KOO'-mah-roo", Cumaru decking and Cumaru lumber are finally getting the recognition they deserve. Cumaru decking is priced comparatively with (and lower than many) composite decking materials. Like Ipe decking, Cumaru decking also has some naturally slip resistant characteristics.

What does Cumaru look like?

Mataverde® Premium Cumaru Decking is all heartwood and can range in color from yellowy browns to reddish brown to a nearly purplish cordovan color. Although the coarser graining of Cumaru decking and Cumaru wood can appear similar to oak, the exotic color range of Cumaru is nothing like oak.

The grain variation of Cumaru is both dramatic and beautiful. Like a hardwood floor on the inside of a home, no two pieces of Cumaru decking will have exactly the same appearance on a Cumaru deck outside your home. This rich variation of Cumaru decking reflects the untamed beauty of this spectacular, all natural exotic decking species.

Cumaru exhibits lots of character striping and color variation and will develop a soft silvery patina if your decking is left to weather naturally.

How to Install Cumaru Decking

The best way to install Cumaru decking is with stainless steel deck screws. Like other high density hardwood decking materials, Cumaru decking should first be pre-drilled and then screwed to the deck joists.

The Ejector screw allows you to screw the Cumaru decking directly to your deck joists without pre-drilling the Cumaru deck boards.

If you don't like the look of decking screws on the surface of your Cumaru deck, the Eb-Ty hidden fastener system is a beautiful way to install Cumaru decking.  You can use pre-grooved Cumaru decking for fast and beautiful installation of your cumaru deck boards.

Mechanical Properties of Cumaru Wood

Cumaru decking and Cumaru lumber have a bending strength of 22,400 psi. That means it would take over 22,000 pounds of pressure per square inch to break a Cumaru board.

Cumaru decking has very little "bounce" to it.

Cumaru has a hardness of 3,340 lbs (making Cumaru more than double the toughness of Oak).  The only high density hardwood decking product that is harder than Cumaru is Ipe. Mataverde® Cumaru Decking has very good dimensional stability and shows only minor movement after it is kiln dried. Mataverde® Cumaru decking and Cumaru lumber are kiln dried to minimize shrinkage and checking to provide a very stable deck surface that is just right for you.
