Commercial Pool Replastering: A Vital Investment for Longevity and Aesthetic Appeal

Commercial pools, whether at hotels, resorts, aquatic centers, or public facilities, endure heavy use and exposure to harsh chemicals and environmental factors.

Commercial pools, whether at hotels, resorts, aquatic centers, or public facilities, endure heavy use and exposure to harsh chemicals and environmental factors. Over time, the pool surface can become worn, damaged, or discolored, impacting both aesthetics and functionality. Replastering a commercial pool is a crucial maintenance step that not only restores the pool's appearance but also ensures its long-term durability and safety. This article explores the importance of commercial pool replastering, signs that indicate it’s time to replaster, the replastering process, and how to maintain a replastered pool.

Why Replaster a Commercial Pool?

Replastering is essential for the following reasons:

  1. Restoring Surface Integrity: The plaster layer in a pool serves as a protective barrier between the water and the https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0151049. Over time, this layer can wear down, leading to cracks, leaks, and rough textures that compromise the pool’s functionality and safety.
  2. Enhancing Aesthetics: A commercial pool is often a key attraction, and its appearance plays a crucial role in maintaining customer satisfaction. Stains, discoloration, and rough surfaces can diminish the visual appeal, making the pool look outdated and uninviting. Replastering revitalizes the pool’s surface, giving it a fresh, clean look.
  3. Ensuring Safety: Worn or rough plaster can be uncomfortable or even dangerous for swimmers. Sharp edges or cracks may lead to cuts and injuries. A smooth, replastered surface ensures a safer environment for guests.
  4. Maintaining Water Quality: Damaged plaster can create spaces where algae and bacteria can grow, making it harder to maintain proper water chemistry. Replastering helps create a smoother surface that’s easier to clean, keeping the water clearer and healthier for swimmers.
  5. Preventing Costly Repairs: Neglecting worn plaster can lead to further damage, such as leaks or structural issues, which can be much more expensive to repair. Replastering extends the life of the pool by addressing these issues before they escalate.

Signs It’s Time to Replaster Your Commercial Pool

Replastering is generally required every 7 to 10 years for commercial pools, depending on usage and maintenance. Some key signs that indicate it’s time to replaster include:

  1. Visible Cracks: If cracks are appearing in the plaster, it’s a clear sign that the surface is deteriorating. Left unaddressed, cracks can lead to water leaks and structural damage.
  2. Stains and Discoloration: Over time, exposure to chemicals, minerals, and organic materials can cause staining and discoloration on the pool surface. If these stains are resistant to cleaning, replastering is the best way to restore the pool’s appearance.
  3. Rough Texture: A smooth surface is essential for swimmer comfort and safety. If the plaster has become rough or pitted, it can be uncomfortable for swimmers and increase the risk of abrasions or injuries.
  4. Chipping or Peeling: If the plaster is chipping or peeling away from the pool’s surface, it’s a sign that the protective layer is failing, and replastering is necessary to prevent further damage.
  5. Water Leaks: A leaking pool is often caused by cracks in the plaster or underlying structure. If you notice that water levels are dropping faster than usual, it may be time to consider replastering.

The Commercial Pool Replastering Process

Replastering a commercial pool is a multi-step process that requires expertise and precision. Here’s an overview of the typical replastering process:

  1. Draining the Pool: The first step is to drain the pool completely. This allows the contractors to access the entire surface area of the pool. Draining should be done carefully to avoid any damage to the pool structure.
  2. Surface Preparation: Once the pool is drained, the old plaster is removed, and the surface is prepared. This involves sanding, chipping away loose plaster, and applying a bond coat to ensure the new plaster adheres properly. Any cracks or imperfections in the pool’s structure are also repaired at this stage.
  3. Applying the New Plaster: After the surface is prepared, the new plaster is applied. Common materials for commercial pool replastering include traditional white plaster, colored plaster, quartz, or pebble finishes. Each material has its own aesthetic and functional benefits, and the choice depends on the pool’s design and usage.
    • White Plaster: The most traditional and affordable option, white plaster provides a clean and classic look. However, it may be more susceptible to staining over time.
    • Colored Plaster: For a more modern and unique look, colored plaster offers various shades that can enhance the pool's visual appeal.
    • Quartz: A durable option, quartz finishes combine plaster with quartz aggregates, providing increased longevity and resistance to stains.
    • Pebble Finishes: Pebble finishes are among the most durable options, offering excellent resistance to chemicals and wear. They also provide a natural, textured appearance.
  4. Curing the Plaster: Once the new plaster is applied, the pool is slowly refilled with water. It’s important to allow the plaster to cure properly to ensure its durability and longevity. This curing process can take several days to weeks, during which time the water chemistry must be carefully monitored and maintained.
  5. Balancing Water Chemistry: The first few weeks after replastering are crucial for maintaining water balance. Proper pH and alkalinity levels must be maintained to avoid scaling or etching of the new plaster. Commercial pool operators should work with a pool service professional to ensure the water chemistry is optimal during this period.

Maintaining a Replastered Commercial Pool

After a commercial pool has been replastered, regular maintenance is essential to protect the new surface and prolong its lifespan. Key maintenance tasks include:

  1. Regular Cleaning: Keeping the pool clean helps prevent staining and the buildup of dirt and debris. Brushing the plaster surface regularly during the first few weeks post-replastering is especially important to remove any loose particles.
  2. Water Chemistry Management: Maintaining balanced water chemistry is critical for the longevity of the new plaster. Monitor pH, alkalinity, calcium hardness, and chlorine levels closely to prevent scaling, etching, and staining.
  3. Preventing Algae Growth: Algae can be a major issue for commercial pools if water chemistry isn’t properly managed. Regular shocking and algaecide treatments help prevent algae from taking hold on the new plaster surface.
  4. Routine Inspections: Regular inspections of the pool’s surface can help detect any early signs of wear or damage. Promptly addressing small issues can prevent more costly repairs in the future.

Conclusion

Replastering is a necessary investment for commercial pool replaster, ensuring both functional longevity and aesthetic appeal. From restoring the pool’s surface integrity to providing a safer and more visually appealing environment for swimmers, replastering is essential for maintaining a high-quality pool experience. By choosing the right plaster material, hiring experienced professionals, and maintaining the new surface, commercial pool operators can extend the life of their pools and avoid more extensive repairs down the line. Regular maintenance and proper water management following the replastering process will ensure the pool remains in excellent condition for years to come.
