Pool resurfacing is one of the largest maintenance expenses a pool owner will face — typically $5,000–$18,000 depending on the finish chosen. For pool service professionals, understanding the options helps you advise clients accurately and positions you as a trusted expert when the conversation comes up.
| Surface | Cost (20K gal pool) | Lifespan | Texture | Maintenance |
|---|---|---|---|---|
| White plaster | $4,000–$7,000 | 7–12 years | Smooth | More demanding |
| Colored plaster | $5,000–$8,000 | 8–12 years | Smooth | More demanding |
| Quartz aggregate | $8,000–$14,000 | 12–17 years | Fine texture | Moderate |
| Pebble aggregate | $10,000–$18,000 | 15–25 years | Rough texture | Less demanding |
Standard white plaster (a mixture of white cement and marble dust) has been the pool surface standard for decades. It's the cheapest resurfacing option and produces the classic bright-white pool appearance. The downside: it's porous and calcium-based, which makes it vulnerable to water chemistry imbalances. Low pH causes etching and surface erosion. High calcium causes scale deposits. Proper chemistry maintenance is more critical with plaster than any other surface type.
For service technicians, plaster pools require more attention. Test calcium hardness monthly and keep it in the 200–400 ppm range. Maintain LSI (Langelier Saturation Index) near zero. Document readings so you can demonstrate to clients that chemistry management is preserving their surface investment.
Quartz finishes like Stonescapes Aqua Blue or Hydrazzo blend white cement with crushed quartz crystals. The quartz adds hardness and improves stain resistance compared to plain plaster. The surface is smoother than pebble aggregate but harder and more durable than plain plaster. Many pool professionals recommend quartz as the best value — it costs more upfront but lasts 50–75% longer than standard plaster, reducing the resurfacing frequency.
Quartz surfaces are also more color-stable than colored plaster. The quartz aggregate maintains color more consistently over its lifespan rather than fading as colored plaster does.
Pebble Tec (and competitors like Pebble Fina, Crystal Bead, and SGM Jewelscapes) use small river pebbles embedded in a cement matrix. The pebbles are naturally smooth but the overall surface has more texture than plaster or quartz. The texture provides grip, which is a safety benefit, but some swimmers find it rough on bare feet in shallower areas.
Pebble aggregate is the most durable pool surface available — 15–25 year lifespans are achievable with good water chemistry management. The pebbles are harder and more chemically resistant than marble dust in standard plaster. The cost premium over plaster is significant, but for a client who plans to stay in their home for 20+ years, pebble aggregate is often the economically rational choice.
When a client asks about resurfacing, pull up their chemistry history in SplashLens and show them how their water balance has tracked over time. Clients with a documented history of aggressive water chemistry need a more durable surface — that's an evidence-based recommendation, not a sales pitch.
Note: discoloration alone is not always a resurfacing trigger. Acid washing can restore a pool with surface staining for $400–$800 — a much less expensive intervention. Before recommending resurfacing, assess whether the surface is structurally sound and whether acid washing could extend its life further.
New plaster requires intensive chemistry management for the first 28 days — the cure period. The "startup protocol" typically involves brushing the pool 2–3 times per day for the first week, maintaining low calcium hardness initially to allow proper cure, and gradually adjusting to target levels. If your client is having their pool resurfaced, be involved in the startup protocol or clearly communicate the requirements to whoever will be handling startup.

Signs include visible rough spots, etching, chipping, staining that won't respond to treatment, chalky deposits on walls, or structural cracks in the plaster layer. Smooth plaster that's just discolored may only need acid washing, which is far less expensive.
Standard white plaster lasts 7–12 years with proper water chemistry maintenance. Quartz aggregate finishes last 12–17 years. Pebble aggregate finishes are the most durable at 15–25 years. Aggressive water chemistry dramatically shortens all surface lifespans.
No. Pool resurfacing requires a completely drained pool and significant prep work including chipping, cleaning, and applying new surface material. The pool must be drained and the work performed by a licensed plastering company.
Pebble Tec is an exposed aggregate finish containing small smooth river pebbles — it's visually rich but textured underfoot. Quartz finishes use finer crystalline quartz aggregate for a smoother surface with better stain resistance than plain plaster, but without the pronounced texture of pebble. Quartz is generally the middle-ground option.
