When a pool needs resurfacing
- The surface feels rough, chalky, or scratches feet and swimsuits
- Stains and mottling return within weeks of an acid wash
- Plaster is delaminating, popping off in sheets, or exposing gunite
- You can see rebar shadowing or rust spots bleeding through
- The pool loses water faster than evaporation explains
- The finish is simply past its expected service life
