Seven Signs Your Pool Needs Resurfacing

Most homeowners can tell something’s wrong with their pool’s surface. What’s harder is knowing what it means, how soon it needs attention, and whether it’s the finish failing or something underneath. This guide walks through the signs your pool needs resurfacing one at a time: how each one looks on white plaster, quartz and pebble finishes, what usually causes it, what usually fixes it, and how urgent it is. It finishes with exactly what to photograph before you call a contractor.

How to read the signs your pool needs resurfacing

Each sign below has the same five parts: how it shows up on each type of finish, the likely cause, the likely fix, what to photograph, and how urgent it is. Urgency uses three levels:

  • Act now. A safety issue, water loss or a possible structural problem. Call someone this month.
  • Plan this season. The finish is failing and won’t improve. Get quotes in the next few months.
  • Budget for later. Cosmetic or early-stage. Watch it and start setting money aside.

One sign on its own rarely means a full resurface. Several signs together, especially across different parts of the pool, usually do.

1. The surface feels rough

  • On white plaster: a sandpaper feel that shows up first on steps, benches and the shallow-end floor, where feet and sun hit hardest.
  • On quartz: roughens more slowly. As the cement between the quartz wears away, the grains stand proud and the surface turns gritty.
  • On pebble: always textured, so roughness alone isn’t the warning. Watch instead for sharp edges where stones have lost the cement around them.
  • Likely cause: years of etching from water that was too aggressive, low in calcium, alkalinity or pH, slowly dissolving the surface.
  • Likely fix: on plaster, an acid wash or light sanding can sometimes buy time, but each acid wash removes a layer of finish. Widespread roughness means resurfacing.
  • Photograph: close-ups of the roughest areas, taken at a low angle so the texture shows, with a coin in the frame for scale.
  • How urgent: plan this season if it’s scraping skin or snagging swimsuits; otherwise budget for later.

2. Stains that won’t clear

  • On white plaster: shows everything. Brown or rust tones, green or black spots, gray blotches and mottling are all obvious.
  • On quartz: the color variation hides light staining, so what you notice tends to be larger patches or white crusty scale.
  • On pebble: staining usually shows in the cement between the stones rather than on the stones themselves.
  • Likely cause: metals in the water (iron from well water, or copper from corroded heater parts or copper-based algaecides), organic debris like leaves, or etching from years of unbalanced water. A rust spot that keeps coming back in the same place can mean reinforcing steel close to the surface.
  • Likely fix: stains from the water can often be treated. Stains that are part of the surface only go away with a new finish. Rust coming through from steel needs a repair before any resurfacing.
  • Photograph: a wide shot showing where the stains are, plus close-ups. If you’ve tried a treatment, take before-and-after photos of the same spot.
  • How urgent: usually budget for later, since most staining is cosmetic. A recurring rust spot moves up to plan this season.

3. Chalky residue or cloudy water

  • On white plaster: run your hand along the wall. If it comes away coated in white powder, the surface is breaking down. The filter may also clog with fine white material.
  • On quartz: less common, but the same hand test applies. Chalking comes from the cement, not the quartz.
  • On pebble: the cement between the stones can chalk the same way, and it’s easiest to feel in the smoother areas.
  • Likely cause: either the surface is dissolving into aggressive water, or minerals are coming out of water that’s too high in calcium and settling as a film. The same symptom can have opposite causes, so a water test comes first.
  • Likely fix: correct the water chemistry and see whether it stops. If chalking continues with balanced water, the finish itself is failing.
  • Photograph: your hand or a white cloth after wiping the wall, and a note of your most recent water test results.
  • How urgent: fix the chemistry right away; the resurfacing decision can be planned this season if chalking continues.

4. Hollow spots and flaking

  • On any finish: the surface sounds hollow when tapped, then eventually cracks open and flakes away, leaving a crater with sharp edges.
  • On pebble: often shows up as a patch where several stones come loose together, rather than single stones.
  • Likely cause: the finish has lost its bond with the shell, from a poor bond when it was applied, water working in behind it, or age.
  • Likely fix: one or two small areas can be cut out and patched. Several areas mean the bond is failing across the pool, and the answer is usually a full chip-out and resurface. See pool repair for when patching makes sense.
  • Photograph: hollow spots are hard to photograph, so record a short video of yourself tapping the area. The sound tells a contractor a lot. Photograph any flaked areas close-up.
  • How urgent: act now once flaking starts, because the sharp edges can cut feet and the loose area keeps growing.

5. Chipping at edges, steps and fittings

  • On white plaster and quartz: chips along step edges, the waterline and around returns, lights and the skimmer, often showing the darker shell underneath.
  • On pebble: individual stones popping out, leaving small pits, especially on steps and benches.
  • Likely cause: edges and fittings are where the finish is thinnest and takes the most wear. Chipping along the tile line can also come from movement where the deck meets the pool.
  • Likely fix: isolated chips can be patched. Chipping in many places points to a worn-out finish. Damage along the tile line calls for checking the joint between the coping and the deck before anything else.
  • Photograph: each chipped area close-up, plus a photo of the tile line and coping all the way around the pool.
  • How urgent: act now for sharp chips on steps and benches, where people put their feet; otherwise plan this season.

6. Cracks in the surface

  • On white plaster: fine spiderweb patterns (crazing) are easy to see, especially on the floor. Line cracks stand out clearly.
  • On quartz: crazing is harder to spot, but line cracks still show, often with dirt collecting in them.
  • On pebble: fine cracks hide between the stones. Look for a line of stones that seem shifted or a crack running across several stones.
  • Likely cause: crazing is shrinkage in the finish layer. A line crack may be surface-only or may run through the shell from settling or ground movement.
  • Likely fix: crazing is normally dealt with at the next resurface. A structural crack has to be repaired before any new finish goes on, or it will crack straight through.
  • Photograph: the full length of the crack with a tape measure alongside, and the date. Mark its ends so you can see whether it grows.
  • How urgent: budget for later for crazing; act now for a line crack alongside water loss, or one that’s growing.

7. Gray or dark worn-through spots

  • On white plaster: gray or darker patches, usually on steps, benches and high-traffic floor areas, where the finish has worn thin enough for the shell to show through.
  • On quartz: areas where the color looks washed out or uneven compared with the rest of the pool.
  • On pebble: bald patches where stones have come out and the bare base shows.
  • Likely cause: age and cumulative wear, often sped up by years of etching and repeated acid washes, each of which removes a little more of the surface.
  • Likely fix: resurfacing. There’s nothing left to restore, and patching a finish this thin doesn’t hold.
  • Photograph: a wide shot on a sunny day with the water still, plus close-ups of the worst areas.
  • How urgent: plan this season. A finish this far gone will only deteriorate.

What to do next

Sort your signs by urgency

If anything you’ve found is in the act now group, such as flaking, sharp chips on steps, or a crack alongside water loss, deal with that first, and look at what pool repair involves. If your signs are mostly plan this season, it’s time to get quotes for pool resurfacing, ideally before contractors’ calendars fill up ahead of the busiest swimming months. If everything is budget for later, keep an eye on it and recheck every few months.

If you’re heading toward a new finish, it helps to think about which one before the first quote. Our plaster vs. pebble vs. quartz comparison and our guide to how long plaster lasts cover the choice, and replastering explains the technical side, including why the first month after the pool is refilled matters so much.

What to photograph before you call a contractor

Any contractor will need to see the pool in person before quoting, but a good set of photos makes the first conversation faster and helps you compare what different contractors tell you. Take them around midday on a sunny day, with the pump and any jets off so the water is still.

  • Wide shots of the whole pool from each end.
  • Close-ups of every problem area, with a coin or tape measure for scale.
  • The tile line and coping all the way around.
  • Steps, benches and the area around fittings, where wear shows first.
  • A short video of you tapping any spots that sound hollow.
  • The equipment pad, including any damp ground around it.

Along with the photos, jot down what you know: roughly how old the pool is, when it was last resurfaced and with what finish, any past repairs, your recent water test results, and whether the water level has been dropping. If you’ve done a bucket test, include the result.
