Appearance and project fit

Cumaru decking boards showing warm tan to reddish-brown color

Cumaru boards showing warm tan to reddish-brown color variation.

Cumaru is commonly called Brazilian Teak. Its visible color can run from warm tan and gold through reddish-brown. Natural boards vary, so mixing boards during installation can create a more balanced finished look.

Compare color, profiles, and project fit with Ipe and Garapa on the Ipe vs Cumaru vs Garapa guide. The right choice depends on the look, profile, budget, and site conditions.

Installation and hardware

Finish, fastening, and technical requirements follow the selected product, manufacturer, and installer documentation. Hardware is sold separately from the lumber.

  • Pre-Grooved boards are typically installed with hidden clips matched to the groove.
  • S4S square-edge boards are typically face-screwed, with an optional plug system.
  • Confirm clip or screw packages with the selected product rather than relying on a universal coverage rule.
