The National Plasterers Council says resurfacing becomes necessary "when problems like cracks and deterioration of the finish can no longer be patched or repaired and/or the pool's appearance is no longer acceptable"[14].
Common signs
Angi lists these signs that a pool needs resurfacing[13]:
- Plaster that flakes or peels
- Surface stains
- A rough plaster surface
- Discoloration
- Cracks
- Rust stains
- Rebound cracks in the pool steps
- On fiberglass pools, a failing fiberglass surface
Terms you will hear
- Delamination: "the separation of a material from itself or from the substrate" (NPC glossary)[17].
- Etching: visible pitting or removal of material from the surface (NPC glossary)[17]. The NPC ties it to aggressive water: low calcium hardness, low pH or low alkalinity[16].
What is usually not a defect
- The NPC's finish disclosure says mottling and color variation are normal for plaster-type finishes, not defects[18].
- It says crazing (fine hairline "check" cracks) is also normal and not a defect[18].
- It says to judge the finish with the pool full of water, in natural light[18].
High water table: don't drain casually
- Pool Pros Construction cites a USGS study finding the shallow (surficial) aquifer under most of Pinellas County is more than 30 feet thick, and the Florida Building Code rule (R4501.21.4) requiring an approved hydrostatic relief device in pools in areas of anticipated water table[6].
- An empty pool on high groundwater can float, crack or tilt. The article says draining for resurfacing should be a planned operation, using the relief device, timed around recent rain and sometimes with active dewatering. It says groundwater rises through the wet season and after heavy rain[6].
- Ask your contractor how they will check the hydrostatic relief valve and control groundwater while the pool is empty.
