Color:

Cumaru varies in grain pattern and color, as all wood. The color of Cumaru varies from golden, tan and reddish brown. You can use its color variation to create patterns or you can oil and sand the wood to create a more uniform appearance. If you don’t oil or seal Cumaru, over time, it will change color to a silver-gray patina; also called sun bleaching sometimes.

Workability:

Because of its hardness and interlocking grain, Cumaru is hard to work with (Janka Hardness: 3,330 lbf or 14,800 N). Before you install screws, it requires pre-drilling and easily blunts drill bits. It’s not recommended to use wood glue since the wood is very dense and oily.

Weight:

Cumaru, thanks to its density, is a heavy wood. It weighs 68 lbs./ft3 (pounds per cubic ft.) on average or 1095 kg/m3 (kilogram per cubic meter). Roughly, this is 5.7lbs per board ft.
