Active work: 5 to 10 business days from drain to refill for most residential St. George pools.
Full cure: 28 additional days of careful brushing and water-chemistry management before the new surface is fully hardened. You can swim during this period.
The short answer by finish type
| Finish | Active days | Total to full cure |
|---|---|---|
| Standard plaster | 5–7 days | ~5 weeks |
| Quartz | 6–8 days | ~5 weeks |
| PebbleTec / pebble | 7–10 days | ~5 weeks |
| Fiberglass gelcoat re-coat | 5–9 days | 3–4 weeks |
The bigger differentiator than finish type is condition of the existing pool. A pool with hollow spots, structural cracks, or plumbing issues adds days regardless of which finish you're picking.
Active work timeline (days 1–10)
Day 1: Drain and disposal
Pool is drained to permitted disposal point (sewer cleanout or other approved location). Takes most of a day with a typical 18,000-gallon residential pool.
Day 2: Surface removal
Old plaster is chipped out (preferred) or sand/bead-blasted off. Loud and dusty. Typically a one-day operation.
Days 3–4: Repairs and prep
Hollow spots cut out and patched, cracks v-cut and stitched, plumbing addressed if needed. Bond coat applied. This is where a quote can stretch — extra repairs add a day or two.
Day 5: Finish application
The new surface goes on. Plaster, quartz, or pebble is mixed and troweled. Once started it can't be paused — the entire pool surface has to be completed in one window so it cures uniformly.
Day 5 (afternoon, pebble only): Acid wash
For pebble finishes, an acid wash exposes the pebble aggregate. Done within hours of application.
Days 5–7: Refill
Refill starts immediately after application (or after acid wash for pebble). 18,000–25,000 gallons takes 24–48 hours from a residential water line.
Days 7–10: Initial chemistry and brush
First chemistry set, initial pool-wide brush, equipment startup. Pool returns to roughly normal appearance and use.
The 28-day cure window
Most homeowners don't know about this part. Even though the pool looks finished after day 10, the new surface is still curing under the water. Full hardness takes 28 days from refill.
- Days 1–14: daily brushing of the entire pool surface to remove plaster dust as it releases. Daily chemistry testing.
- Days 14–28: brushing tapers to every other day. Chemistry stabilizes; calcium hardness gradually brought up to target.
- Day 28+: surface fully cured. Automatic vacuums and standard maintenance resume.
You can swim during the cure window. Rough play and diving should wait until day 14 or so.
What can stretch the timeline
- Mid-summer heat (June–August). Plaster cures too fast in extreme heat. Crews often slow the schedule or shift to early-morning application windows.
- Weather events. A summer monsoon downpour during application is a disaster. Crews postpone if storms are forecast.
- Hidden damage discovered mid-job. Extra repairs add 1–3 days.
- Tile and coping bundled in. Adds 2–4 days to the active window.
- HOA architectural approval. SunRiver, Entrada, and similar communities can add 2–4 weeks before work even starts.
- Booking lead time. The good St. George crews are booked 4–8 weeks out, especially March–November.
Best time of year to schedule
October–November is the gold-standard window in St. George. Temperatures mild for curing, contractor schedules opening up, and the pool is ready for next swim season.
March–April is the second-best window. Same mild temps, but contractors fill up fast as everyone tries to get their pool ready by Memorial Day.
Mid-summer is doable but suboptimal. Heat accelerates plaster cure unevenly, and you'll lose 2–3 weeks of prime swim season.
Winter (December–February) works in mild years but a cold snap during cure can crack plaster. Pebble finishes are more tolerant.

Frequently asked questions
Can I rush a pool resurface to be done before a party?
Not really. The active work can sometimes be compressed to 5 days, but you can't compress the 28-day cure window. Plan backward from your deadline — for a Memorial Day pool, schedule start by early April.
Will it really take 5 weeks total?
Yes if you measure to full cure. But the pool is usable from about day 10 onward — you just have to follow the cure-period chemistry plan during the remaining time.
Can I be home during the noisy work?
Yes, but the chip-out phase (day 2) is genuinely loud — pneumatic chippers running for hours. If you work from home, plan to be elsewhere that day.
How far in advance should I book?
4–8 weeks for spring/fall windows in St. George; 2–4 weeks for winter; same-week is sometimes possible for mid-summer (but you may not want to schedule mid-summer anyway).
