Fibreglass swimming pools are popular among homeowners for their low maintenance and quick installation. However, like any pool, they can develop cracks over time. Here are some essential tips and tricks for repairing your fibreglass swimming pool to ensure it remains in top condition.
What is a Fibreglass Pool?
Fibreglass pools are large, moulded structures made from resins and fibreglass, coated with a non-porous gel layer. They offer a variety of shapes and sizes to suit different backyard spaces and aesthetic preferences.
Unlike concrete pools, which can take months to construct, fibreglass pools can be installed relatively quickly, often within a few weeks. Once installed, they are surrounded by concrete for stability, ensuring they stay in place and maintain their shape.
A fibreglass pool is renowned for their smooth, non-abrasive surface, which is gentle on the skin and resistant to algae growth, making routine pool maintenance much easier. This makes them an attractive option for many homeowners seeking a hassle-free swimming pool experience.
Signs Your Fibreglass Pool Needs Repair
Hairline Cracks
Hairline cracks, also known as spider cracking, are small, superficial cracks that appear in the gel coating of the fibreglass pool. These cracks are typically cosmetic and do not affect the structural integrity of the fibreglass pool repair itself. However, they can detract from the pool’s appearance, making it look older and less well-maintained than it actually is.
Larger Cracks
While hairline cracks are mainly an aesthetic issue, larger cracks can signal more significant problems. Cracks that are more than 1/8 inch wide or over a foot long might indicate a structural issue, such as a problem with the pool’s foundation.
These larger cracks can lead to leaks, which, if left unaddressed, can cause further damage to the whole pool structure and surrounding area.
If you notice substantial cracks in your fibreglass pool, it is essential to act quickly. Contacting a professional pool repair company for service can help prevent the problem from worsening and save you from costly repairs down the line.
Importance of Fibreglass Pool Repair
Ignoring minor cracks in your fibreglass pool can lead to more extensive damage over time. Small cracks can expand and deepen, eventually requiring more complex and expensive repairs.
Additionally, larger cracks can cause water to leak out of the front pool walls, leading to several issues:
- Water Loss: Persistent leaks can result in significant water loss, increasing your water bills and the environmental impact of refilling the pool frequently.
- Structural Damage: Water that leaks through cracks can seep into the ground beneath the pool, potentially eroding the foundation. This can cause the pool to shift or settle unevenly, leading to further structural damage.
- Chemical Imbalance: Leaks can disrupt the balance of chemicals in your pool, making it harder to maintain safe and clean water. This can lead to additional maintenance costs and effort.
By addressing cracks promptly, you can prevent these problems and ensure your pool remains safe, functional, and visually appealing.

6 Essential Tips for Fibreglass Pool Repairs
1. Drain and Dry the Pool
The first step in any pool repair process is to first dry completely drain the pool completely. Ensure it is dry before starting any repairs.
This allows for a thorough inspection before fixing cracks and ensures that the repair materials adhere properly to the surface. Repairing a dry pool also helps to avoid complications from working underwater, which can be challenging and less effective.
2. Sand the Damaged Area
Using an electric sander, sand down the area around the crack to remove any loose debris residual dust and paint. This step is crucial as it creates a clean, smooth surface for the repair materials to adhere to. After sanding, clean the area with a cloth and acetone to remove any remaining dust and debris. Avoid using manual sandpaper, as it won’t provide the same smooth and even result.
3. Mark and Cut Out the Damaged Area
Using a marker, draw a 10cm border around the crack. Attach a diamond-edge cutting wheel to your sander and cut out the marked area to the depth of the crack. This step removes the damaged material and prepares the area for the repair.
Cutting out a slightly larger area ensures that you address any underlying issues and provide a more secure surface layer for repair.
4. Apply the Bond Coat
Mix the bond coat according to the instructions provided in your pool repair kit. Using a putty knife, apply the bond coat to the pool filled cut-out area, making sure it is smooth and level with the pool’s surface. The bond coat acts as a base layer, filling the crack and providing a strong foundation for the subsequent layers.
5. Apply the Putty
Mix the epoxy with the polyester putty as per the instructions in your repair kit. Apply the putty over the bond coat with a putty knife, ensuring it is evenly spread and smooth. Once the putty is dry, sand it down to create a seamless surface. Clean the area again with acetone to remove any sanding debris.
6. Apply Gel Coat and Fibreglass Cloth
Mask off a 10cm area around the repair with masking tape. Using a paint roller, apply the gel coat to the masked-off area. While the gel coat is still wet, place the fibreglass cloth on top and use a ribbed roller to remove any air bubbles.
Apply another layer of gel coat over the fibreglass cloth and let it dry. Once the gel coat issue the fibreglass product is dry, sand the area lightly and clean with acetone. Finally, apply a sealant to the repaired area and let it dry for 2-3 days before refilling the swimming pool.
How ecoFINISH® Improves the Process

Unlike traditional cementitious finishes, which can be difficult and often require a complete remodel or resurfacing for even minor damages, ecoFINISH® coatings provide an easy and efficient repair solution. Minor cosmetic damage can be addressed simply by reheating and melting the material to heal gouges and cuts, restoring the glossy finish.
For more extensive repairs, the ecoFINISH® surface can be cut back around the damaged area, and after the structural repair, the coating is reapplied and blended seamlessly.
