Your swimming pool is more than just a place to cool off; it’s the centerpiece of your backyard oasis. Over time, however, the surface that makes it sparkle can begin to show its age. The plaster finish, which keeps your pool sealed and gives it that smooth, inviting look, eventually wears down. When that happens, a pool plaster renovation becomes essential. This guide will walk you through everything you need to know about bringing your pool’s surface back to life, from spotting the warning signs to choosing the perfect new finish.
Why Pool Plaster Health is Crucial
The plaster in your pool serves two primary functions. First, it creates a watertight seal, preventing water from seeping into the concrete shell and the ground beneath. This barrier is critical for the structural integrity of your pool. Second, it provides a smooth, comfortable, and aesthetically pleasing surface for swimmers. A deteriorating plaster finish not only looks bad but can also feel rough on your feet and skin. Maintaining your plaster is not just about looks; it’s about protecting your investment and ensuring a safe, enjoyable swimming experience.
Signs It’s Time for a Pool Plaster Renovation
How do you know when your pool is crying out for a renovation? The signs are often visible and can progress from minor issues to significant problems. Keep an eye out for these common indicators.
1. Stains and Discoloration
Are there stubborn stains on your pool’s surface that regular cleaning and chemicals can’t remove? These are often caused by minerals, metals like iron and copper, or organic debris. While some surface stains are normal, widespread or deep-set discoloration can mean the plaster is becoming porous and absorbent, signaling that its protective qualities are fading.
2. Rough Texture (Pool Rash)
Run your hand along the pool surface. Does it feel rough, sandy, or like sandpaper? This condition, often called “pool rash,” is a clear sign of etching and erosion. The plaster is breaking down, becoming abrasive and uncomfortable for swimmers. This roughness can easily scrape skin and snag swimsuits.
3. Cracks and Crazing
Visible cracks are a major red flag. Small, web-like “craze cracks” might just be in the surface layer, but larger structural cracks can indicate a more serious problem with the pool’s shell. Any crack allows water to penetrate the plaster, which can lead to further damage. It’s crucial to have these inspected by a professional immediately.
4. Plaster Flaking or Peeling (Spalling)
If you see pieces of plaster chipping off or settling at the bottom of your pool, this is a condition known as spalling. It happens when the plaster loses its bond with the concrete shell underneath. This is a definitive sign that the plaster has reached the end of its lifespan and needs a complete replacement.
The Pool Plaster Renovation Process: What to Expect
Replastering a pool is an intensive process that should be handled by experienced professionals. While specifics can vary, the general steps remain consistent.
- Draining the Pool: The first step is to completely drain the pool. This is done carefully to prevent hydrostatic pressure from damaging the pool shell.
- Preparation and Undercutting: The crew will prepare the surface by undercutting the tile line and around fittings like lights and jets. This ensures the new plaster has a clean edge to bond to.
- Chipping or Sandblasting: The old, damaged plaster is removed. This is typically done by chipping it away with specialized tools or by sandblasting the surface. The goal is to create a rough, clean canvas for the new layer to adhere to.
- Washing and Inspection: After the old plaster is gone, the shell is acid-washed to remove any remaining debris and neutralize the pH. The crew will inspect the bare shell for any structural cracks that need to be repaired before proceeding.
- Applying the New Plaster: This is where the magic happens. The plaster mixture is prepared and skillfully troweled onto the pool’s surface by a team of applicators. They work quickly and precisely to create a smooth, consistent finish.
- Initial Filling and Curing: Immediately after the plaster is applied, the pool must be filled with water without interruption. The water helps the plaster cure properly. This initial curing period is critical for the long-term durability of the new surface.
Choosing Your New Plaster Finish
When it’s time to replaster, you have several options beyond the standard white plaster. Each comes with its own look, feel, and price point.
Standard White Plaster
This is the classic, most affordable choice. It’s a simple mixture of white cement, marble dust, and water. It creates the traditional light blue water color and has a typical lifespan of 7-10 years with proper care.
Aggregate Finishes
These have become increasingly popular due to their durability and beauty. Small pieces of quartz, pebbles, or glass beads are mixed into the plaster.
- Polished Aggregate: These finishes contain finely crushed stone (like marble or quartz) and are polished smooth, creating a durable and stain-resistant surface.
- Exposed Aggregate: This type uses small river pebbles or glass beads. After application, the top layer of cement is washed away to expose the aggregate, resulting in a slightly textured, natural look. These finishes are extremely durable, often lasting 15-20 years or more.
Tile Finishes
For the ultimate in luxury and longevity, a full tile finish is an option. Glass or ceramic tiles cover the entire pool surface. While this is the most expensive route, a tile finish can last for decades and offers endless design possibilities.
Understanding the Costs and Maintenance
The cost of a pool plaster renovation varies widely based on your pool’s size, the type of finish you choose, and your geographic location. A standard plaster job can start around a few thousand dollars, while high-end aggregate or tile finishes can cost significantly more.
After your pool is replastered, proper maintenance during the first month is crucial. Your pool professional will provide specific instructions for this “startup” period, which usually involves:
- Brushing the entire pool surface twice daily for the first few weeks to remove plaster dust.
- Maintaining strict chemical balance to help the plaster cure correctly.
- Avoiding automated pool cleaners, which can damage the soft new surface.
Don’t Wait—Restore Your Pool’s Beauty and Function
A pool plaster renovation is a significant undertaking, but it’s one of the best investments you can make for your home. It restores your pool’s beauty, ensures its structural safety, and enhances your family’s swimming experience for years to come. If you’re noticing stains, cracks, or a rough surface, it’s time to take action.
