Over time, even the most well-built concrete pools show signs of wear. Surface degradation, rough textures, stains, and cracks can make a pool less enjoyable and potentially unsafe. This is where concrete pool resurfacing becomes essential. Whether it’s for aesthetic improvement or structural restoration, resurfacing plays a major role in maintaining a pool’s longevity and usability.
When to Consider Resurfacing
Concrete pools typically require resurfacing every 10 to 20 years, depending on the original finish, maintenance routine, and exposure to chemicals and weather. Common signs that indicate the need for resurfacing include peeling plaster, rust stains, cracks, discolouration, and a rough or pitted surface. In some cases, persistent leaks may also be traced back to surface damage, making resurfacing not just a cosmetic fix but a practical repair solution.
Preparation Process
Concrete pool resurfacing involves more than simply applying a new layer. The process begins with draining the pool and inspecting the surface. Any loose or damaged material must be chipped away, and cracks need to be repaired using appropriate bonding agents or hydraulic cement. Sandblasting or hydroblasting may be used to clean and prepare the surface for the new finish, ensuring proper adhesion and durability.
Types of Resurfacing Finishes
Several material options are available for concrete pool resurfacing. Each comes with its own look, feel, durability, and cost.
Plaster (Marcite): A traditional choice that offers a smooth, clean finish. Though cost-effective, it typically has a shorter lifespan compared to other options and may be more prone to staining.
Pebblecrete or Exposed Aggregate: This finish consists of cement mixed with small pebbles or stones. It provides a textured, natural appearance and is highly durable.
Quartz Aggregate: A blend of plaster and quartz crystals that improves durability and enhances the aesthetic with a speckled, colourful surface.
Glass Beads: These provide a high-end, reflective finish that’s smooth and visually striking. While more expensive, it adds a unique look to the pool.
Tiles: Ceramic or glass tiles are the most long-lasting option but also the most labour-intensive and costly. Tiles offer virtually unlimited design options and superior resistance to chemical wear.
Timeline and Costs
The duration of a resurfacing project varies depending on the size of the pool, the extent of preparation needed, and the chosen finish. Most projects can be completed within one to two weeks. Costs also vary, with basic plaster resurfacing being more affordable and finishes like tiles or glass beads sitting at the higher end of the scale. Additional charges may apply for structural repairs, equipment upgrades, or improvements to the surrounding pool area.
Post-Resurfacing Care
Once resurfaced, the pool should be properly refilled and balanced with appropriate water chemistry. For the first few weeks, careful monitoring of pH, calcium hardness, and chlorine levels is essential to protect the new surface. Some finishes may require a curing period before regular use resumes. Regular maintenance going forward—such as brushing, chemical checks, and avoiding harsh water conditions—can significantly extend the lifespan of the resurfaced pool.
Concrete pool resurfacing is a practical solution to restore both function and appearance. By addressing surface issues promptly and choosing a suitable finish, pool owners can extend the lifespan of their pool and enjoy a refreshed swimming environment for years to come.
