Fiberglass Pool Refinishing: Restore the Look and Feel of Your Pool
A fiberglass pool is a great investment for homeowners who want a sleek, low-maintenance option that’s both durable and beautiful. But like anything exposed to the elements year after year, even fiberglass pools eventually show signs of wear. Fading, surface cracks, discoloration, or a chalky texture are all common issues that can develop over time.
When that happens, fiberglass pool refinishing becomes an essential solution—not only to restore the look of your pool, but to improve its safety, longevity, and comfort. In this guide, we’ll walk you through what fiberglass pool refinishing is, how to know when it’s needed, and why partnering with a professional is the key to long-term results.
Why Fiberglass Pools Deteriorate Over Time
Fiberglass pools are built using a smooth, protective gel coat that creates a vibrant, glossy finish. While this surface is strong and easy to clean, it isn’t immune to wear and tear. Over time, environmental exposure, improper chemical balances, and heavy use can begin to break down the gel coat, leading to visible and structural issues such as:
- Fading or discoloration from prolonged UV exposure
- Surface blistering (osmotic blisters) or bubbling
- Rough, chalky textures that feel unpleasant underfoot
- Hairline cracks or spider cracks in the surface
These issues can reduce the pool’s aesthetic appeal, make cleaning more difficult, and potentially compromise the pool’s structure if left unaddressed.
Top Signs Your Fiberglass Pool Needs Refinishing
Not sure whether it’s time to refinish? Here are some of the most common indicators:
- Dull Appearance or Discoloration
Has your pool lost its shine? Faded or stained surfaces are often the first sign the gel coat is wearing down. - Chalky Surface Texture
If the surface feels gritty or leaves a powdery residue on your hand, the topcoat is deteriorating. - Blistering or Bubbling
Surface bubbles or blisters can form due to water penetrating the fiberglass layer—this should be addressed promptly. - Visible Cracks
Cracks not only affect aesthetics but could also lead to more serious leaks or damage over time. - Water Loss or Difficulty Maintaining Chemicals
Unexplained drops in water level or frequent chemical imbalances can be signs the pool’s surface is compromised.
How the Fiberglass Pool Refinishing Process Works
Refinishing a fiberglass pool is more than a cosmetic upgrade—it’s a structural restoration that requires proper preparation and application for lasting results. Here’s what the process typically involves:
- Draining and Inspection
The pool is drained completely to expose the interior surface. Technicians then assess the current condition and identify any needed repairs. - Surface Preparation
The old gel coat or damaged top layer is sanded or chemically etched to create a rough surface for optimal bonding. Any loose or damaged areas are removed. - Repairing Cracks and Blisters
Cracks, pits, and blisters are filled with fiberglass resin or putty and smoothed out to restore the pool’s shape and integrity. - Priming and Coating
A primer or bonding agent is applied, followed by a new gel coat or resurfacing layer. This new finish restores the pool’s color, texture, and water resistance. - Curing and Refilling
Once the coating cures (usuallyover several days), the pool is cleaned, refilled with water, and ready for swimming again.
The result? A smooth, vibrant, and durable pool surface that looks brand new.
Why You Should Leave Refinishing to the Pros
While DIY refinishing kits are available, this is not a project we recommend for homeowners. Refinishing fiberglass pools requires technical knowledge, professional-grade materials, and careful surface preparation. Any errors—like poor bonding or uneven application—can lead to peeling, bubbling, or re-damage within a short time.
