How well does it work?

  • Difficult to work with, especially when sawing. Ipe can have a severe blunting effect on cutters.Reducing the cutting angle 15° is recommended for planing and moulding. Pre-drilling is necessary for nailing, but the lumber will hold screws well. Lumber will generally finish smooth, but there is potential of tear out in interlocked areas. Surface preparation for Ipe is required for gluing. Ipe finishes and polishes well, but the yellow powdery deposits can interfere.

Seasoning and Durability

  • Heartwood is very resistant to attack by decay fungi and termites. Ipe is considered to be one of the most durable lumbers on earth.

Other notes on Ipe

  • Ipe can be referred to as Brazilian Walnut, mostly based on the brownish look of the lumber . Ipe has no relation to species known as Walnut. The wood can be similar in looks to Cumaru to the point where it is hard to distinguish between the two, but Ipe will have a darker color and will lack a vanilla-cinnamon like scent while being worked.


  • Ipe has been reported to cause skin, eye, and respiratory irritation. Other effects, such as headaches or disturbance of vision may occur, but overall severe reactions are uncommon. The yellowish powder in Ipe may cause dermatitis in some people.
