The Pool Resurfacing Process, Step by Step

How long does pool resurfacing take? The short answer

Swimply's 2026 guide puts most resurfacing jobs at about 5 to 14 days of active work. The pool is then refilled right away, and the first weeks after the fill are part of the job too.

Published figures from the sources named. Weather, repairs, tile work and the contractor's schedule can stretch any step.

A full remodel with new tile, coping, decking or equipment takes longer. An Arizona builder reports remodel timelines of about 3 to 6 weeks in winter and up to 5 to 9 weeks in summer. See pool remodeling for that bigger job.

Step 1: Inspection and quote

The contractor looks at the surface, the tile line and the equipment, and asks about leaks. One trick the trade uses is listening for hollow spots: Pool & Spa News describes dragging a chain or rod across the surface, where a hollow area sounds like tapping a bucket. Hollow, or delaminated, plaster has to come off.

This visit decides the scope: which finish, which color, how the old surface will be prepared, whether tile or coping is included and who handles the drain and startup. Get all of it in writing. Our pool resurfacing cost guide has a checklist for comparing what a quote includes.

Step 3: Prep the surface: chip-out or bond coat?

Prep is where good and bad resurfacing jobs part ways, because a new finish is only as good as what it sticks to. There are two main approaches, and the condition of the old surface decides which one fits.

Summarized from Pool & Spa News trade coverage (2013 and 2016). Your contractor decides after inspecting your pool.

Crews typically cut a clean line just below the tile, tape over the tile to protect it and work carefully around fittings so the new finish meets them neatly. With a bond coat, the old surface is first roughened, by acid washing, sandblasting or water jetting, then cleaned so nothing loose is left behind. Pool & Spa News reports that crews let a bond coat sit at least a day but no more than about three before the finish goes on.

Contractors don't all agree on the cutoff. The same trade coverage notes that some crews do a full chip-out once more than 10 percent of the surface has come loose, while others wait until about 25 percent. Ask which method your contractor plans and why.

Step 5: Apply the new finish

Most finishes go on in about 1 to 2 days, according to Swimply. Plaster and quartz are troweled smooth. Pebble finishes are applied, then washed so the tops of the stones show. A crew works fast, because cement-based finishes start setting as soon as they're mixed.

The finish you choose changes the look, feel and lifespan more than the schedule. Compare them in our plaster vs. pebble vs. quartz comparison, or read about pool replastering and pebble pool finishes.

Step 7: Startup: brushing and balancing the water

Startup is the step homeowners most often handle themselves, and it matters. New cement-based finishes release fine dust, and the water chemistry swings while the surface settles. The NPC start-up procedure (revised March 2021) lays out a day-by-day plan. In plain terms:

1. Days 1–3: start the pump and brush

   Start the filter as soon as the pool is full. The NPC says to run it nonstop for seven days, or until the dust is gone and the water is clear, and never less than 72 hours. Brush the whole surface at least twice a day. Balance alkalinity first, then pH, then calcium, in small steps. The NPC says not to add chlorine for the first 48 hours.

2. Day 3: add chlorine

   Once the water is in range, the NPC plan brings chlorine to about 1.5 to 3 ppm.

3. Days 4–7: keep brushing daily

   Keep brushing every day to help prevent scale. Calcium is raised slowly and stabilizer (cyanuric acid) is added over several days.

4. After day 7: brush as needed

   Once the dust is gone, brushing can drop back to normal cleaning. Any leftover dust comes out with a brush-type vacuum.

5. Through day 28: extra care

   The NPC says a new finish is most prone to staining, scaling and discoloration in the first 28 days. Skip wheeled cleaners until then, and wait 30 days before adding salt for a salt system.

Pebble Technology's own startup sheet is stricter on brushing: three times a day for the first 3 days, then twice a day for the next 10. It also says not to use heaters for 14 days or wheeled automatic cleaners for 28 days, and that the finish develops most of its durability in the first 28 days. Your contractor's written plan for your exact product wins over any general guide, including this one.

What Phoenix heat changes

The steps are the same everywhere. In the Valley, heat changes when they happen and how carefully they're done.

Scheduling

An Arizona builder calls winter the best time to remodel a pool here, with fall a close second and July and August the hardest months. Rosie on the House advises against draining a pool in an Arizona summer unless it's necessary. Arizona's monsoon season runs June 15 to September 30, and storms can bring dust into a freshly filled pool or rain that raises groundwater around an empty shell.

Application and cure

Heat speeds up drying. The same Arizona builder warns that plaster applied above 90°F in low humidity can dry too fast and end up weaker. An NPC technical bulletin covered by Aqua Magazine says heat raises the risk of shrinkage cracking and uneven color, and suggests starting early in the morning, cooling the materials, using a set retardant per the maker's directions, and shading hoses and materials or tenting the pool. For bond coats, Pool & Spa News reports advice to finish the work before the air or the pool surface reaches 90°F.

Heat also affects startup. Water temperature is one of the inputs to the saturation index the NPC uses to balance new-pool water, so the right chemistry in a hot month isn't the same as in winter. That's one more reason to test often and follow the startup plan closely.

• Ask what time of day the crew will apply the finish in warm months.
• Ask how they'll keep materials and the shell cool, and whether they use a retardant.
• Ask how long the pool will sit empty, and what happens if a storm hits.
• Plan startup for a stretch when someone can brush daily.
