Lesson 1Edge treatment and finishing materials: solid wood edging, edge banding, veneers, paint-grade vs. stain-grade surfacesLearn ways to treat exposed edges and finish bench surfaces. Compare solid wood edging, edge banding, and veneers, and choose paint-grade or stain-grade materials for strong, good-looking results.

Compare zinc-plated and stainless fasteners, when to use better coatings, and how clear coats, paint, and waxes guard metal in busy indoor areas.

Compare pine, poplar, and oak, plus kiln-dried and surfaced stock, focusing on strength, steadiness, straightness, and cost for reliable, creak-free framing.

Compare wood, structural, pocket, and confirmat screws, plus building adhesive, focusing on where each works best, needed pilot holes, and ways to avoid splits.
