Workability

Guajavira wood is moderately difficult to work with both hand and machine tools due to its high density. It has good nailing and screwing properties, but pre-drilling is recommended. It can be stained, polished, and finished to enhance its natural beauty. The wood is known for its excellent dimensional stability and resistance to warping.
