Pool Surfaces and Finish Care
Treat plaster, pebble, tile, vinyl, and fiberglass as different maintenance systems with different failure modes.

- Do not acid-wash or sand a finish based on internet advice without confirming the surface type
- Do not apply startup or warranty rules from one surface type to a different finish
- Do not skip water balance and brushing before escalating to destructive surface work
Identify your pool surface type using builder records or visual inspection before choosing any cleaner, acid, or treatment.

pH / TA / CH / CSI
Know which surface you actually have
A lot of bad maintenance starts with calling everything 'plaster' or treating every smooth wall like vinyl.
Calcium and CSI are surface-dependent
Low calcium matters much more to cementitious finishes than it does to vinyl or fiberglass shells.
Use the least aggressive correction first
Surfaces are easier to damage than to restore.
Startup and repairs are their own category
Fresh surfaces and patched areas need documentation and finish-specific care.
