Heartwood and sapwood distinct by color; golden-yellow heartwood, darkening to yellow-brown; moderate brightness; imperceptible smell and taste; medium density; moderately hard to cut; reverse grain; medium texture.
The heartwood is resistant to attack of fungi of white and brown rot. In field trials carried out by EMBRAPA in the Amazon, Tatajuba wood has shown to have a natural durability of more than seven years. Considered moderately resistant to attack by marine pin hole. In contact with the soil, it can have a useful life superior to 25 years. Tatajuba wood is difficult to treat with preservative solutions, even under pressure. It presents low permeability to creosote (oleo soluble) preserving solutions, even under pressure.
The wood of tatajuba is easy to be worked, both with manual or mechanical tools, producing great finishing. It does not accept nails with ease. Pre-drilling of brads is recommended. Air-drying is slow without defects. When drying in oven it presents a slight tendency to warpage, twisting and recessing. Careful process control is recommended to avoid defects.
