Cumaru decking is one of the hardest woods sold and is ideal for exterior construction.  It is strong, hard, long lasting, rot and insect resistant, stands up to extreme weather, does not get hot in the sun, and is all natural. Cumaru is often used for luxury interior flooring, especially to create a seamless indoor-outdoor design.

Alternate Names:

Cuamru is also known as Brazilian Teak, Fabaceae, Dipteryx Odorata, Tonga or Tonquin, Almendrillo, and sometimes Ipe Champagne. Alternate spellings for Cumaru are Coumaru, Kumaru or Kumarú.


As all wood, Cumaru has variations in color and grain pattern. The color of Cumaru varies from tan, golden, and reddish brown.  The color variation can be used to create patterns, or the wood can be sanded and oiled, which will create a more uniform look.  If Cumaru is not sealed or oiled it will change color over time to a silver-gray patina, which is sometimes referred to as sun bleaching.


Cumaru is difficult to work with because of its hardness (Janka Hardness: 3,330 lbf or 14,800 N) and interlocking grain.  It requires pre-drilling before installing screws and will easily blunt drill bits.  It is not advised to use wood glue as the wood is oily and is very dense.


Cumaru is a heavy wood, thanks to its density.  It weighs an average of 68 lbs/ft3 (pounds per cubic foot) or 1095 kg/m3 (kilogram per cubic meter).  This is roughly 6.3 lbs per board foot.
