In Wood Species, Floors, Rough sawn


Couratari oblongifolia
Other names:
Estopeiro, imbirema, tauari-amarelo and tauari-morrão.
General features:
Heartwood and sapwood undisturbed by color; yellowish-white to light yellowish-beige; moderate brightness; variable smell from little perceptible to perceptible, in this case unpleasant, slightly bitter taste; medium density; soft to cut; right grain; texture medium.
Durability and Treatment:
Natural durability: It presents low resistance to attack by xylophagous organisms (fungi and termites). Some species show tendency to blue stain, caused by staining fungi, and should be used dry and protected from humidity. In a field test, in contact with the soil, this wood was considered as non-durable, with a life of less than two years. Treatability: tauari wood, in laboratory tests, when submitted under pressure treatment, has been shown to be permeable to preservative solutions. It is very easy to be treated with both creosote (soluble oil) and CCA-A (water soluble), when applied under pressure.
Processing Characteristics:
Workability: Tauari wood is moderately soft to the cut, presenting a good finish, although sometimes the surface looks fluffy. Some species have silica, which contributes to the wearing down of tools. Drying: The air-drying rate is moderate, with a slight tendency to warpage and surface cracking. Drying in oven is fast, without significant defects, but may have cracks and moderated twisting.
