That wall of cryptic numbers and colors in the sandpaper aisle doesn't have to be a guessing game. This episode breaks down the three engineering decisions baked into every sheet: grit grading systems (CAMI vs. FEPA), backing materials (paper, cloth, film, mesh), and abrasive minerals (aluminum oxide, silicon carbide, ceramic, garnet). We walk through the exact grit progression for building a white oak desk, explain why open-coat paper is essential for pine, and reveal when stearate coating helps versus hurts. Plus: the real cost of cheap sandpaper isn't the price per sheet—it's the ruined finishes and wasted time.
