Every number below comes from a named source listed at the bottom of this page. National figures are labeled as national; they are not Las Vegas quotes. Checked October 23, 2026.
Typical life by finish (national)
- National Plasterers Council: white plaster 5–8 years, quartz 10–15, pebble 12–18, polished finishes 8–12[15].
- Angi (national): plaster about 10 years, aggregate 20+ years; paint has to be reapplied every 2–7 years[14]. Angi's FAQ also says a well-applied plaster finish lasts 5–10 years on average, depending on water chemistry[14].
- Concrete pools: Angi says a concrete pool lasts 50+ years and needs resurfacing every 10–15 years[16].
Water chemistry is the big variable
- The NPC says "aggressive" water, with low calcium hardness, low pH or low alkalinity, etches and deteriorates the finish[17].
- It recommends testing pH, alkalinity and chlorine 1–2 times a week, and calcium hardness, cyanuric acid and total dissolved solids monthly; its ideal saturation index is 0.0 to +0.3[17].
How long each finish lasts in Las Vegas
| Finish | Lifespan claims (Paragon Pools[2]) |
|---|---|
| White plaster | 5–7 years; replaster "every 5–8 years for standard plaster". |
| Quartz aggregate | 10–12 years. |
| Pebble (Pebble Tec, Pebble Sheen) | 15–20 years. |
Paragon says most Las Vegas pools show etching, staining or roughness "within 5–8 years of the last plaster job" and recommends upgraded finishes because of the hard water and sun[2]. PoolPad's Las Vegas page gives longer figures, 10–15 years for white plaster and 15–20+ for pebble[1]. Treat all of these as company and directory claims.
Hard water and calcium
- The Southern Nevada Water Authority says the valley's water hardness is "280 parts per million or 16 grains per gallon, categorized as 'very hard,'" mostly calcium and magnesium from the Colorado River supply[5].
- Paragon calls hard water "the #1 enemy of pool plaster" in the valley. It says it causes etching, staining and roughness, and that calcium buildup on waterline tile is commonly removed by bead blasting every 1–3 years[2].
- Paragon also says start-up chemistry matters more here because "an improper startup can lead to premature calcium scaling on the new surface"[2]. Cali Pool Plastering recommends a professional start-up service for chemical introduction, brushing and water balancing while the finish cures[3]. Get your contractor's start-up instructions in writing, because they usually govern the warranty.
How long the job takes
Angi: 5–7 days for most resurfacing jobs, 1–2 days for paint, up to 14 with bad weather or a remote location[14].

How often should a pool be resurfaced?
Angi says concrete pools need resurfacing every 10–15 years[16]. The NPC's typical surface life runs from 5–8 years for white plaster to 12–18 for pebble[15].
What makes a finish wear out early?
The NPC points to aggressive water (low calcium hardness, low pH or low alkalinity), which etches the surface[17].
