InstaBidsGunite pool resurfacing options?
Gunite pool resurfacing options differ in texture, appearance and care: NPC lists white plaster at 5–8 years, quartz at 10–15 and pebble at 12–18. Choose smooth plaster or polished aggregate for a smoother feel, or compare quartz and pebble samples for texture; include startup care and substrate preparation in the written scope.

Compare pool finish texture and published life
| Options | Surface feel | Published life description | What resurfacing changes |
|---|---|---|---|
| Traditional white plaster | Hard-troweled smooth finish. | 5–8 years in NPC’s finish description; a published range, not a prediction for your pool. | Cementitious, nonstructural finish. Specify substrate preparation separately. |
| Quartz aggregate | Can range from smooth to textured; name the exposure technique. | 10–15 years in NPC’s finish description; a published range, not a prediction for your pool. | Cementitious, nonstructural finish. Specify substrate preparation separately. |
| Pebble aggregate | Textured finish; compare a physical sample. | 12–18 years in NPC’s finish description; a published range, not a prediction for your pool. | Cementitious, nonstructural finish. Specify substrate preparation separately. |
| Polished aggregate | Smooth surface with exposed-aggregate appearance. | 8–12 years in NPC’s finish description; a published range, not a prediction for your pool. | Cementitious, nonstructural finish. Specify substrate preparation separately. |
Why the life estimates need their source labels
| Options | What the source describes | How to use it |
|---|---|---|
| White plaster in commercial guidance | ADH describes cement and marble dust plaster, gives 7–15 years, and says it becomes rougher with age. | A commercial operator guide’s description; keep it separate from NPC’s finish range. |
| Aggregate in commercial guidance | ADH groups small pebbles or quartz aggregate with cement and gives 15–20 years. | A grouped aggregate row, not a separate prediction for every quartz or pebble finish. |
Separate surface choice from shell condition
A finish is not the structure
ACI describes pool plaster as nonstructural. Compare the finish separately from repairs to the concrete shell.
Installation affects the finished surface
ACI describes typical double-back application in two coats and inherent variations in waviness, levelness, thickness and smoothness. Put preparation and the accepted sample in the scope.
What is the best pool resurfacing material?
Choose a gunite pool finish by its feel, appearance and care requirements. NPC describes pebble as textured and a 12–18 year surface; polished aggregate offers a smooth exposed-aggregate look and an 8–12 year range. Compare samples before choosing the texture you will touch on steps and benches.
White plaster offers a smooth, hard-troweled surface. Quartz can vary from smooth to textured, so a bid should name the finish and exposure method rather than rely on “aggregate” alone.

How long does pool resurfacing last?
NPC lists white plaster at 5–8 years, quartz at 10–15, pebble at 12–18 and polished aggregate at 8–12. Those are finish descriptions rather than warranty terms. Startup care matters: NPC calls for frequent brushing and daily water testing and adjusting after the pool is filled.

Is quartz pool finish smoother than pebble?
Quartz is not automatically smooth: NPC says its finish can vary from smooth to textured, while pebble is described as textured. NPC’s quartz life description is 10–15 years. Request a sample of the exact aggregate and exposure method, especially for shallow steps and seating where finish feel matters.
ACI explains that finishing techniques can produce smooth or textured surfaces. Treat appearance and touch as separate choices from the aggregate’s name.

What is a polished aggregate pool finish?
Polished aggregate combines a smooth surface with an exposed-aggregate appearance. NPC describes an 8–12 year surface, compared with its 12–18 year description for pebble. Choose polished aggregate when that smoother appearance suits the pool; record the exact product and sample rather than treating all aggregate finishes as identical.

What care does a newly resurfaced pool need?
A newly resurfaced cementitious finish needs a written startup plan. NPC calls for frequent brushing and daily testing and adjusting of pool water, and highlights susceptibility to staining, scaling and discoloration during the first 28 days. Specify who handles the startup work and supplies the finish-specific instructions.

Does new pool plaster repair the gunite shell?
Pool plaster is a nonstructural finish in ACI’s description. ACI describes typical placement in two coats, creating the surface that follows the pool’s curves. Separate shell repairs from the finish specification so a resurfacing bid states how existing defects will be assessed before the new interior finish is applied.

What to put in your written pool resurfacing scope
- Name traditional plaster, quartz, pebble or polished aggregate and attach the selected sample.
- Record whether the finish should be smooth or textured, especially on steps and benches.
- Separate structural shell repairs from the nonstructural finish work.
- Describe substrate preparation and the proposed cementitious finish system.
- Describe placement, detailing around curves and the agreed finish tolerances.
- Assign startup brushing and daily water testing and adjusting.
- Include finish-specific instructions for the first 28 days and what to do about staining or scale.
