Lesson 1Edge treatment and finishing materials: solid wood edging, edge banding, veneers, paint-grade vs. stain-grade surfacesLearn options for treating exposed edges and finishing bench surfaces. Compare solid wood edging, edge banding, and veneers, and decide when to use paint-grade or stain-grade materials for durable, attractive results in local climates.
