Mondio is pinkish brown to red brown, sometimes olive brown. The wood contains a white substance in the pores. It has clearly demarcated sapwood. The grain is straight or interlocked and the texture is medium. The grain is sometimes wavy. It has an unpleasant odour when green. Density at 12 % moisture content: 0.74 g/cm3.The wood is relatively easy to machine. Pre-drilling is recommended and finishing and gluing are reported to be good. The blunting effect is normal and peeling and slicing is reported to be good. Some species can be siliceous and present an important blunting effect. In this case, it is necessary to use adequate tools. It dries normal to quickly with a (small) tendency to warp or check. There are variable risks of distortion according to the species. High humidity recommended during the first stages of drying in order to reduce defects. Initial surface drying prior to kiln drying is recommended in order to reduce defects.

Mandio is moderately durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood).

Mandio can be used for several applications such as:
• interior: e.g. panelling, furniture, veneer, flooring, seats, boxes and crates, tool handles (resilient woods), joinery, sliced veneer, moulding, formwork
• exterior: e.g. panelling, ship building, wood frame house, park benches, cladding, boardwalks, heavy carpentry, joinery, vehicle or container flooring, open boats.
