Indicators of a healthy hardwood finish include a uniform sheen and the absence of bare wood visibility in high-traffic walkways. A reliable test for finish integrity is the 'bead test,' where small drops of water should sit on the surface rather than soaking into the wood fiber. If the wood darkens quickly upon contact with moisture, it indicates a compromised finish. Furthermore, the finish should be free of significant surface haze, deep gouges, or peeling, which suggest that the protective layer requires professional screening or refinishing.
