This wood type is very common to Nicaragua, where it is goes by the name, Nanciton. Its most valuable and common usage is in furniture and home construction.

When using fasteners with Nancitón, pre-boring is recommended. It is a highly workable hardwood either by hand or machine due to minimal dulling effect. Due to the porosity of Nancitón grain, it is recommended to use multiple coats when sealers or finishes are applied. Glue holds up well in interior conditions.
Without experience, Suradan can be difficult to dry. However, when dried properly, defects can be reduced, and drying time moderate. Kiln schedules T5-D3 and T3-D2 are recommended for 4/4 and 8/4 stock, respectively.
Suradan’s durability is rated very high owing to its natural resistance to decay and insect attack in tropical conditions. Treatment is not required, but in exterior uses, a UV protective coating is recommended to preserve the natural color.
