Workability

Generally machines, sands, glues, and finishes well, though figured grain may tear out during planing. Pre-drilling is advisable for fasteners.

Finish Recommendations

Use a clear oil, wiping varnish, lacquer, shellac, or polyurethane; avoid heavy staining, which can obscure the natural color. Sand evenly and apply a wash coat if blotching occurs.
