Fiberglass pools are known for their sleek look, durability, and low-maintenance lifestyle—but behind that beautiful surface lies an unsung hero: the gelcoat. While it may not get much attention at first glance, gelcoat plays a major role in both the performance and appearance of your fiberglass pool. Let’s explore what gelcoat is, how it’s applied, and why it matters when considering a fiberglass pool installation.
What is Gelcoat?
Gelcoat is a smooth, high-performance resin that forms the outermost layer of a fiberglass pool. Think of it as both the protective shield and the polished face of the pool shell. It gives fiberglass pools their signature glossy surface, vibrant color, and soft-to-the-touch feel.
But gelcoat isn’t just about aesthetics. It’s specially formulated to resist UV rays, chemicals, algae buildup, and minor abrasions. That means your pool not only looks good—it stays that way with minimal effort.
How Is Gelcoat Applied?
The process of applying gelcoat begins early in the pool manufacturing process. After a perfectly prepared mold is cleaned and treated, the gelcoat is sprayed evenly across its surface. This must be done in a climate-controlled environment to ensure flawless application and optimal curing conditions.
Once applied, the gelcoat is allowed to cure before additional layers of resin and fiberglass reinforcement are added. This layered process creates a smooth, strong, and waterproof shell that’s built to last.
The result is a beautifully finished pool surface that resists staining, fading, and wear—ready to be installed in your backyard oasis.
Benefits of a Gelcoat Surface
When it comes to pool ownership, gelcoat offers a host of benefits that go beyond first impressions:
- Low Maintenance: Unlike concrete or vinyl liners, gel-coated surfaces are non-porous. That means they naturally resist algae growth, making your pool easier to clean and requiring fewer chemicals.
- Color Longevity: The gelcoat finish is engineered to resist fading from the sun and pool chemicals, so your pool’s color stays true season after season.
- Comfortable Texture: No rough concrete or sharp edges here—gelcoat creates a silky-smooth finish that’s gentle on feet, hands, and swimsuits. Better yet, gelcoat is naturally slip-resistant for enhanced grip even when wet.
- Visual Appeal: Available in a wide range of colors and shimmer effects, gelcoat lets you personalize the look of your pool. Whether you’re drawn to a deep, dramatic blue or a light, beachy teal, gelcoat makes your vision possible.
- Durability: With proper care, the gelcoat surface can last for decades without the need for resurfacing, making it a smart, long-term investment.
Caring for a Pool with Gelcoat
While a gelcoat surface is easy to care for, it still needs to be cared for and isn’t a “set it and forget it”.
Essentials for caring for a gelcoat pool surface:
- Balance the water using LSI to prevent damage
- Keep chlorine levels at 1-3 ppm (parts per million)
- Avoid calcium hypochlorite and instead use liquid chlorine
- Follow best practices and recommendations from the installation team
Finally, test the water regularly. This is the best way to notice changes early and prevent major damage before it happens.
