What is a fiberglass reinforced resin pool coating?
The fiberglass reinforced polyester resin pool coating is an innovative waterproofing solution
designed to address the challenges of traditional coatings such as plaster,
paint, and mosaic tiles. It also overcomes the technical limitations
of membranes like vinyl liners and reinforced PVC.
Characteristics and Implementation
This composite pool coating owes its exceptional strength to the process of lamination—
a technique that combines polyester resin with a reinforcement material,
fiberglass.
Applied in successive layers, the liquid resin saturates the fiberglass, bonding together as it hardens in the open air
to form a thick, durable and seamless structure.
The same lamination technique is widely used in the construction of pleasure boat hulls,
showcasing its versatility and proven effectiveness.
The strength of fiberglass-reinforced polyester resin is derived from several key characteristics
inherent to this composite material:
Mechanical Resistance: The unique composition of this approximately 3.5 millimeters thick
shell gives it remarkable resilience against mechanical stresses, including the risks of punctures,
tears, and acts of vandalism to which flexible Vinyl Liners may be exposed.
Chemical Resistance: Polyester resin offers excellent chemical resistance, notably to saltwater and chlorine.
This resistance results in a coating that does not easily degrade over time, unlike flexible PVC materials
that can deform due to a temporary chemical imbalance in the water.
Resistance to Deformation: The sturdy fiberglass shell remains unaffected by repeated foot traffic
from swimmers and withstands temperature variations without deforming.
Aesthetics
The liquid application of resin provides exceptional flexibility, allowing the coating to conform seamlessly
to even the most intricate shapes and fine details. This process ensures a superior aesthetic finish while
maintaining the highest standards of functionality.
From an aesthetic perspective, traditional options like vinyl liners and reinforced PVC membranes
have certain limitations that reinforced resin can effectively overcome:
The Vinyl Liner
A Vinyl Liner is a flexible membrane made from polyvinyl chloride (PVC) that lines the interior of the pool,
providing a waterproof barrier. It is custom-fabricated to fit the shape and dimensions of the pool
and is installed as a single piece that rests against the pool’s walls and floor.
Since the liner is not permanently bonded to the structure, it may develop folds, creases, or wrinkles,
particularly in corners, curves, or areas with steps. These imperfections can become more noticeable
over time and may trap dirt and debris.
While vinyl liners offer a budget-friendly waterproofing solution, they are more susceptible
to punctures, tears, and fading compared to more durable options like fiberglass-reinforced resin coatings.
Reinforced PVC
Reinforced PVC is thicker than a traditional vinyl liner and is installed using pre-cut strips
that are welded together through thermal fusion.
However, this process creates a unique challenge: the seams.
Over time, impurities can accumulate along these welds, causing the seams to become more prominent
and creating visible lines. Although arranging the welds thoughtfully during installation can
help to reduce the visibility of these lines, it does not completely eliminate the issue.
Suitable for Freeform Pools
The unique properties of reinforced resin enable a high-end coating that smoothly adapts
to the fluid shapes of freeform pools, avoiding the need for traditional joints found between tiles
or seams seen in reinforced PVC membranes.
The absence of these potential weak points results in a seamless,
wrinkle-free appearance and enhances the durability of the pool surface.
This coating excels in its ability to seamlessly conform to intricate features such as fittings,
gutters, and stairs. The Gelcoat finish provides a smooth, uniform surface that minimizes the risk of algae
and dirt buildup, even in hard-to-clean corners.
Its adaptability ensures that maintenance remains easy, regardless of the pool's complex shapes or elaborate contours.
Enhancing Old Pools
The polyester resin coating gives pool owners the flexibility to implement structural upgrades easily.
Adding corner stairs is achievable without creating vulnerable seams that could compromise aesthetics and waterproofing.
Constructed from concrete blocks, the stairs are integrated into the pool's structure and encapsulated within
a fiberglass-reinforced resin shell.
This rigid, non-deformable shell conforms precisely to the shape of the stairs, providing a
smooth and uniform finish.
It adapts to any shape, filling and covering the roughness of concrete surfaces, making it an ideal choice
for renovations and projects with complex or custom designs.
The resin coating effectively seals the junction between the pool's structure and its fittings,
ensuring that main drains, skimmers, return inlets, and light fixtures are seamlessly integrated.
For rigid flanges designed for liners, the polyester resin lamination overlaps the fitting’s seat,
with the styrene in the resin providing an excellent bond.
The rigid flange is then replaced and securely fixed over the polyester coating.
The reinforced resin is compatible with all types of fittings, including skimmers and return inlets,
even those without flanges for mosaic pools. In such cases, a specialized resin-based adhesive ensures
a reliable and durable seal between the fittings and the coating, guaranteeing long-lasting integration.
Water Quality of your Pool
The quality of your pool water relies not only on the filtration system and the correct use of maintenance
products but also on the surface of the pool itself. The type of coating used for waterproofing significantly
influences how impurities adhere to the pool walls.
Rougher coatings tend to trap more deposits on their surface, while wrinkles can create
spaces where dirt accumulates, promoting the growth of algae.
Structurally Independent
When a pool's structure undergoes changes, such as the development of micro-cracks,
it can directly affect coatings that rely on the stability of the underlying surface,
such as paint, plaster, and tile finishes.
Plaster, for example, is closely tied to the condition of the substrate on which it has been applied.
As the surface deteriorates or cracks, the plaster inevitably follows suit, leading to further cracking
and potential crumbling. This compromises the pool's waterproofing and often results in frequent and costly repairs.
In contrast, a reinforced resin shell offers a more resilient solution.
Similar to a boat hull, it forms a solid, uniform barrier that adheres to the pool's interior
while maintaining structural independence. Unlike plaster and tile coatings, the composite nature
of reinforced resin often allows it to retain its integrity regardless of changes in the substrate.
As a result, it is a more reliable choice for pools where the underlying structure may be prone
to weakening over time.

What is Gelcoat Finish?
Gelcoat is commonly used to cover fiberglass-reinforced structures, such as laminated pool coatings
and boat hulls.
It can be applied using a brush, roller, or spray gun, depending on the scale of the project
and the desired outcome.
Typically, Gelcoat is applied in two layers: The first layer remains tacky and does not dry when exposed to open air.
The second layer, known as the Topcoat, contains paraffin, allowing it to dry in the open
air and create the glossy, smooth finish with reflective
qualities that are characteristic of pools coated with polyester resin.
The Qualities of Gelcoat
Gelcoat has many advantages:
Pleasant to the touch
Easy maintenance
Wide choice of colors
UV resistant, preserves its color over time
Excellent resistance to scratches, impacts, and chemicals
Minimizes the buildup of algae and other impurities

Epoxy Resin Pool Coating
High Temperature Resistance
Epoxy resin is highly resistant to elevated temperatures, making it an excellent choice for pools where
the water is heated above 30°C. This is particularly relevant for balneotherapy pools,
where maintaining high water temperatures is essential.
Odorless Application
Unlike polyester resin, which can emit strong odors during application, epoxy resin is virtually odorless.
This makes it a preferred option for locations such as public facilities that remain operational during
waterproofing work, where minimizing disruption is important.
Longer Application and Curing Time
While epoxy resin offers several benefits, it requires a longer application process and curing time
compared to polyester resin. This extended time frame should be considered when planning pool
renovation or waterproofing projects.
A Bit of History on Fiberglass Reinforced Polyester
Introduced in the 1950s, fiberglass reinforced polyester transformed the shipbuilding industry
with its remarkable combination of strength and lightness. This composite material gained significant
popularity, especially in the 1980s, when it became the material of choice for building pleasure boats.
Shipyards around the world embraced polyester and its derivatives due to their superior
durability and resistance to harsh marine environments.
The advantages of reinforced polyester extended beyond shipbuilding. Its excellent corrosion resistance,
durability against wear, and resilience in demanding aquatic conditions led to its widespread
use in other water-related applications, such as manufacturing canoes, kayaks, and surfboards—equipment
that must withstand similar conditions to those found at sea.
The material's success eventually reached the pool industry, where its robustness,
low maintenance requirements, and aesthetic qualities made it a preferred option for pool coatings.
This innovation enabled the industry to meet growing demands for durable,
easy-to-maintain, and visually appealing pools.
Today, fiberglass reinforced polyester remains a material of choice for waterproofing pools and ponds,
maintaining its position as a trusted choice in various aquatic applications.
Implementation of the Fiberglass Reinforced Polyester Pool Coating
Applying a fiberglass reinforced polyester pool coating begins with cutting fiberglass mats to the exact
dimensions of the pool. The substrate is then meticulously prepared through thorough cleaning and mechanical
surface preparation, including grinding to create the ideal texture for adhesion.
Any holes or cracks are repaired to ensure a smooth surface.
An adhesion primer is applied across the entire area, playing a vital role in absorbing residual moisture
and ensuring optimal adhesion for the subsequent layers.
The fiberglass is laid out and impregnated with marine-grade isophthalic anti-electrolysis polyester resin,
applied in successive layers. Two layers of fiberglass, fully saturated with the polyester resin,
are manually applied to achieve the optimal optimal thickness and waterproofing.
Once the fiberglass layers have hardened, the surface is sanded using a grinder to achieve a smooth,
defect-free finish. After grinding, all dust is removed, and the pool is thoroughly cleaned.
Finally, a first layer of Gelcoat resin in the chosen color is applied to the surface.
The final layer of special marine paraffin Topcoat is applied, completing the pool’s waterproofing process.
After a 7-day hardening period (allowing time for the solvents in the resin to fully evaporate),
the pool is thoroughly rinsed and then filled.
Lamination work is frequently carried out under special shelters. Thus, work is possible all year round.
The ambient temperature is maintained at the ideal level using construction heaters.
