What is pool replastering?
Plaster is the classic interior finish for concrete (gunite) pools. It's a cement-based coat, traditionally made with white cement and marble dust, troweled over the pool shell to make it smooth and watertight. Over time, sun, water chemistry and wear break it down.
It's a type of pool resurfacing. If you're weighing plaster against tougher options, compare it with a quartz pool finish or a pebble pool finish. Our plaster vs. pebble vs. quartz comparison puts cost, lifespan and feel side by side.

Signs your pool needs replastering
- Rough or sandpaper-like surface that scrapes feet
- Flaking, chipping or peeling patches
- Stains or dark blotches that don't come out with brushing
- Hollow-sounding spots when tapped (the plaster has separated)
- Fine cracks or crazing across the surface
- Chemical use creeping up, or algae that keeps coming back
That last one matters more than people think. Rosie on the House notes that worn, porous plaster can soak up chemicals, and some pool service companies may even decline to keep servicing a pool that uses so much. Fixing the surface can make routine care easier and less expensive.
A white or gray crust at the waterline isn't always a plaster problem. It's often mineral scale on the tile from hard water. That can sometimes be cleaned rather than replaced. See pool tile and coping.
Do you need a full replaster, or something less?
Not every tired-looking pool needs new plaster. A licensed pro can tell you which of these fits:
| Problem | Often fixed by | Notes |
|---|---|---|
| A few chips or a small crack on sound plaster | Spot repair | Patches can stand out against older plaster. |
| Heavy calcium or stains on otherwise solid plaster | Drain, acid wash and polish | Rosie on the House describes this for heavy calcium buildup. It removes a thin layer of plaster, so it isn't endless. |
| White ring only at the waterline | Tile cleaning or new tile | See pool tile and coping. |
| Rough, flaking, hollow or widely stained plaster | Full replaster or an upgraded finish | The worn coat comes off and a new one goes on. |
General guidance only. The contractor who inspects your pool can tell you what it needs.
How long does pool plaster last in Arizona?
Pool plaster typically lasts about 5 to 10 years in Arizona, compared with 10 to 15 years in milder climates, according to an Arizona pool builder. Rosie on the House also cites 5 to 10 years. Strong sun, heat, hard water and heavy chemical use wear it down faster here.
Intense UV, long hot summers and heavy chemical demand speed up etching and staining. Hard water adds calcium buildup. Water that's out of balance, either too acidic or too scale-forming, damages plaster quickly.
| Finish | Reported lifespan in Arizona | Arizona builder cost range |
|---|---|---|
| White plaster | 5 – 10 years | $3,500 – $6,500 |
| Quartz | 7 – 18 years (by source) | $7,000 – $10,000 |
| Pebble | 15 – 30 years | $6,000 – $15,000 |

How much does it cost to replaster a pool?
Replastering a pool in Arizona typically costs about $3,500 to $6,500, or roughly $3 to $6 per square foot, based on an Arizona builder's early 2026 figures. National 2026 guides put it at $5,000 to $10,000. Larger pools, spas, repairs and tile work raise the price.
Rosie on the House notes that larger pools cost noticeably more than average-size ones, since size drives how much material and labor the job takes.
Other things that move the price include repairs, how much old plaster has to come off, an attached spa, tinted colors, tile work and startup care. Our pool resurfacing cost guide breaks down each one.

Inspection
The contractor checks the surface, looks for hollow spots, cracks and leaks, and confirms the scope and color.
Drain the pool
Water is pumped out following your city's rules, usually to landscaping or the home's sewer cleanout at a slow rate.
Prep the shell
The old plaster is chipped out, ground or acid-washed so the new coat bonds well. Loose material is removed.
Repairs
Cracks, damaged steps and fittings are repaired. Tile work is done now if it's part of the job.
Apply plaster
The crew trowels on the new coat. National guides put finish application at about 1 to 2 days.
Refill and start up
Refilling begins right away and usually takes 24 to 48 hours. Then comes a startup period of careful brushing and water balancing.
For the full timeline, including chip-out versus bond coat prep, the nonstop fill and the National Plasterers Council's day-by-day startup plan, see our pool resurfacing process guide.
How to care for new pool plaster
The first few weeks decide a lot about how long new plaster lasts. New plaster is very alkaline and releases fine dust as it cures. Typical guidance includes:
- Brush the whole surface at least twice a day for the first two weeks.
- Test the water often and keep pH in the range your contractor gives you, commonly about 7.2 to 7.8.
- Avoid harsh chemicals and cleaners during the first weeks.
- Hold off on heating the pool until the plaster has cured, which some guides say can take up to 28 days.
- Follow your contractor's specific startup plan. It may differ by product.
How soon can you swim after replastering?
Plan on about one to two weeks. PoolResearch says to wait at least five days after the pool is filled and recommends two weeks. Orenda, a pool chemical maker, says at least seven days. Swimming too early can scuff or mark the soft new surface.
- First 24 hours: no swimming at all. PoolResearch calls this the most important curing window.
- Days 1 to 5: keep brushing and test the water daily. New plaster pushes pH around, and pH that's far off can irritate eyes and skin.
- After about two weeks: most owners swim normally once the water is clear and balanced, while still brushing and testing.
- Heating: guidance varies, from day five (Orenda) to up to 28 days (PoolResearch). Use your contractor's date.
PoolResearch notes plaster keeps curing for months, so gentle use and balanced water still matter after you're back in.
When is the best time to replaster in Arizona?
The best time to replaster a pool in Arizona is late fall through early spring. Plaster applied above 90°F in low humidity can dry too fast and end up weaker, and dry summer heat can crack an empty pool's plaster. Demand is lower in winter, too, so scheduling is easier.
| Months | Conditions | What it means for a resurface |
|---|---|---|
| November – February | Cool, slower season for builders | Best window for curing; easier scheduling. Phoenix names Jan – Mar billing cycles as its cheaper refill time; in Scottsdale, a Dec – Feb refill affects sewer charges. |
| March – May | Warming; demand and prices tend to peak | Still workable, but book early. Plan around 3 – 6 months ahead. |
| June – September | Triple-digit heat; monsoon season (June 15 – Sept. 30) | Hardest time. Fresh plaster can dry too fast, and storms can bring dust, debris and delays. |
| October | Cooling, fall season | A strong second choice; finishes before Scottsdale's December – February sewer window. |

Monsoon storms add two risks for a resurface. Dust and debris can blow into a freshly filled pool during startup, when the surface is still soft. And heavy rain can raise groundwater around an empty shell, which PoolResearch warns can push it up. A good contractor watches the forecast and keeps the pool empty as briefly as possible.

Who can legally replaster a pool in Arizona?
In Arizona, a full replaster should be done by a company with a B-5 or B-6 swimming pool contractor license or the R-36 plastering classification. The R-6 pool service and repair license does not allow complete replacement of plaster or pebble interiors. Verify any license with the Registrar of Contractors.
The Arizona Administrative Code lists an R-36 Plastering classification that covers pool interiors (excluding tile), and B-5 and B-6 swimming pool contractor licenses that cover building and repairing pools. Some companies hold a dual license instead, such as KA-5 or KA-6, which combine the commercial pool classes with residential B-5 or B-6 under Arizona's dual license rules.
Before you hire anyone, look them up on the Arizona Registrar of Contractors website to confirm the license is active and fits the work. Our pool resurfacing FAQ covers more hiring questions.

Frequently asked questions
How long does pool replastering take?
Most replastering jobs take about one to two weeks from draining to refill, depending on prep and repairs. National guides list 4 to 5 days for drain and prep and 1 to 2 days to apply the finish. Refilling takes another day or two, then you'll spend roughly two weeks brushing and balancing water during startup.
How often should you replaster a pool?
Nationally, Bob Vila puts resurfacing at about every 10 to 12 years. In Arizona, plain plaster often needs it sooner, around 5 to 10 years, because of heat, UV and hard water. Let the surface guide you more than the calendar: roughness, flaking, stains and rising chemical use are the real signals. Tougher finishes stretch the interval.
Can I replaster over old plaster?
Sometimes a contractor can apply new plaster over the old coat after thorough prep, but loose, hollow or delaminated plaster has to come off first or the new layer may fail. That's a judgment call for a licensed pro after inspecting your pool. Ask each contractor exactly how they'll prepare the surface.
Is white plaster still a good choice in Arizona?
It can be, especially on a budget or if you'll sell soon. It's the least expensive finish, and Rosie on the House calls replastering one of the most common pool renovation jobs, with most owners choosing plaster again. The trade-off is a shorter life here, often 5 to 10 years, so compare cost per year against quartz or pebble.
Why is my new plaster dusty?
New plaster releases fine cement dust as it cures, which is normal during the first weeks. Brushing twice a day sends that dust toward the filter and helps prevent it from setting as blotches. If dust or discoloration continues well past startup, contact the company that did the work about their startup and warranty process.
What color plaster should I choose?
White gives the classic light-blue water look. Tinted and darker plasters change the water color and can hide some debris, but Rosie on the House notes darker finishes hold more heat and make it harder to see someone on the bottom. Ask to see a wet sample, since color looks different under water.
Will replastering fix a leaking pool?
Not by itself. A new finish can seal minor surface problems, but leaks from cracks, plumbing or fittings must be found and fixed before plastering. National cost guides stress that repairs come first. If your water level keeps dropping, ask the contractor about leak detection as part of the inspection.
