How do you know a pool needs resurfacing?
The surface tells you first. Plaster that used to feel smooth starts to feel like fine sandpaper, which usually means the top layer has worn away. Stains that will not scrub out, especially dark blotches, often mean the finish can no longer resist minerals in the water.
Delamination is the sign to act on fastest. Once a patch of plaster starts to separate from the shell, water gets behind it and the flaking spreads on its own. A pool losing more water than a bucket test explains may have a shell or plumbing crack rather than a surface problem.
Many pools in Mandarin, Orange Park, and Ponte Vedra date to the 1980s and 1990s and are on a second or third finish, often pairing a worn surface with electrical that predates current code.
