The integrity of a finish is typically indicated by its sheen and its ability to repel liquids. A worn finish will show visible dullness or scuffing in areas of high activity. The 'bead test'—placing a drop of water on the surface—is a simple diagnostic tool; if the water beads, the finish is intact, but if it penetrates the wood and causes darkening, the finish is worn through. Deep scratches, color changes, or splintering are severe indicators that the protective layer is no longer shielding the wood fibers.

What signs indicate the finish layer is wearing out?
Visible signs of wear include a dull, hazy appearance in traffic areas, loss of luster, and localized scratches. If water no longer beads on the surface and instead soaks into the wood, or if grey spots appear, the finish layer has likely been compromised and requires attention.
