Workability

Sanding: Clogs abrasives; frequent sandpaper changes are required.
Nailing: Good holding ability.
Finishing: Natural oils may interfere with adhesion and drying of some finishes. To reduce the wood’s tendency to repel finish coats, surface resins may be removed with a solvent that is compatible with the finish to be used.
