Working notes

In the shop, generally hard to work with on account of its irregular grain and high density. Cebil also has a pronounced blunting effect on cutters.

Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with curupay.

Curupay should be sold by project fit: colour, workability, durability, and the format the customer actually needs.

Use caution

Avoid specifying it by name alone; confirm board size, moisture, colour, figure, and the project environment before buying.

Finish strategy

Test finishes on offcuts first, especially when colour, blotching, outdoor exposure, or grain filling matters.

Buying note

Choose boards, slabs, plywood, blanks, or posts based on the project rather than species name alone.
