What are Fiberglass Swimming Pools benefits compare to Concrete or Vinyl liner Pools

Fiberglass swimming pools come in pre-assembled forms complete with stairs, ledges and in-built ladders. They are also available in many sizes and shapes. Fiberglass swimming pools are very popular as both domestic as well as commercial swimming pools. A fiberglass swimming pool is a little more expensive than a concrete pool or vinyl liner pool but it has several advantages and requires much less maintenance which makes it a good investment.

Advantages of fiberglass swimming pools

Some of the advantages of fiberglass swimming pools over concrete and vinyl liner pools have been listed here.

1. Fiberglass swimming pool requires less maintenance. This is because the inner surface finishing of the pool called gel coat is nonporous in nature and does not allow water penetration of the shell of the swimming pool. The gel coat also prevents algae growth and reduces the amount of purifying chemicals needed to be added to the pool water. Not more than half hours a week of maintenance work is required for fiberglass swimming pools.

2. Fiberglass swimming pools are built-off site and not at the location. This ensures that they can be installed much more swiftly as compared to concrete or vinyl liner pools and are ready to be used within 3-4 weeks.

3. The fiberglass shell does not require resurfacing or replacement of vinyl liner as is the case with concrete and vinyl liner swimming pools. Thus, the cost of upkeep of the fiberglass shell is negligible.

4. The gel coat of a fiberglass swimming pool is smooth and non-abrasive. Thus, the inner surface of the swimming pool is not harsh on the bodies of the swimmers.

5. Ladders, steps and seating are in-built into the shell of a fiberglass swimming pool. Thus, there is no additional cost to install them as is the case with concrete and vinyl liner swimming pools.

Reasons for water penetration in a fiberglass swimming pool

Even though there are many benefits associated with fiberglass swimming pools, problems can arise when the gel coat wears out or is damaged after a period of time which is usually 10-25 years. The gel coat can suffer algae growth, develop osmosis spots, develop black spots and other problems which compromise its integrity. In such a state, the gel coat is no longer able to protect the fiberglass shell of the pool from water invasion.

Results of water invasion

The fiberglass shell is made of strands glass fibres reinforced by resin. Water invading the shell through the damaged and porous gel coat causes rotting of the fiberglass fibers. This ultimately results in the fiberglass shell losing its structural integrity and eventually collapsing. Therefore, waterproofing becomes critical in case of a compromised gel coat in a fiberglass swimming pool.

How to waterproof the gel coat?

Epotec is a high-grade epoxy pool paint which has been specifically designed for swimming pool waterproofing. It is no ordinary epoxy paint but a pool grade epoxy paint which can remain immersed in water for years on end. Epotec forms a hard wearing coating over the gel coat which prevents both liquid and gaseous water molecules from gaining entry into the shell of the fiberglass swimming pool. The epotec coating remains unaffected by UV rays of the sun, purifying chemicals such as chlorine, body fats, body lotions, etc.

Prior to upgrading the gel coat, it is necessary to go for fiberglass swimming pool repair. The worn out or damaged gel coat must be repaired. Re-fiberglassing may also be required for fiberglass pool repair if the glass fibers have started to rot due to water invasion. Necessary repairs to the structure may also be required to be carried out.

Surface preparation is also essential before applying epotec. Un-reacted styrene may be present on the surface. It needs to be eliminated to avoid reaction with the epoxy coating. Epotec is applied in two coats. The curing time is 5-7 days. The result is a hard wearing coat which lasts 7-14 years.

Beneficial features of epotec

Some of the beneficial features of epotec pool paint which makes it highly suitable for fiberglass as well as concrete swimming pool waterproofing have been mentioned here.

1. Epotec is a 100% solid pool paint. This means that the paint has no thinners or solvents in its chemical
composition. As a result, the paint forms a solid coating which does not shrink as it cures. A conventional
paint has just 30-40% solids.

2. Epotec is chemically inert. Therefore, the coating cannot be removed by chemicals. The chemicals present in the pool water also have no effect on the coating. The coating can only be removed by mechanical wear and tear.

3. The thickness of the coating is same as the applied thickness since there is no shrinkage after curing. This is the reason one should make the coating as much thick as possible.

4. The life of the coating depends upon the thickness of the coating. The coating usually lasts for 7-14 years without the need for recoating.

5. Epotec comes in the form of 2-pack paint. It is easy to apply using brushes or rollers. You can apply it yourself or hire a professional for the job.

6. Epotec comes in a multitude of colours such as slate grey, chamois, opal, whisper grey, royal blue, sky blue, white, etc.

Swimming pools of all sizes and types whether in domestic households or commercial establishments require waterproofing to maintain their structural integrity. A strong and durable waterproofing solution is required for swimming pools for long term protection against pool water. Epotec epoxy paint Sydney is such a waterproofing solution developed for swimming pools. This is a solid paint with zero solvent content which provides flawless waterproofing for as much as 14 years. The paint coating remains unaffected by chemical content of the pool water and the UV rays of the sun.

Used for a variety of pools

The epoxy paint uses Sydney cover a plethora of swimming pool types including concrete and fiberglass swimming pools.

Concrete swimming pools- If you are going for concrete swimming pool construction Sydney, using epotec epoxy paint for waterproofing the inner surfaces is the best choice. Pool water makes its way through the inner surface of a concrete swimming pool in the absence of waterproofing. The water is detrimental to the steel reinforcements present in the structure of the concrete swimming pool and causes corrosion, concrete cancer and other types of damage. This leads to breakdown of the concrete swimming pool structure. By using epotec paint, such a scenario is avoided because water is unable to penetrate the concrete surface due to the presence of epotec coating. Upgrading the inner surfaces with epotec during concrete swimming pool repair Sydney in case of old swimming pools having some other type of waterproof finish is also recommended.

Concrete swimming pools with marblesheen finishing can also be waterproofed using epoxy paint for concrete Sydney. Marblesheen is a mixture of white cement and crushed marble chips which are used to give a finishing of 5-20 mm to concrete swimming pools. Marbelsheen finishing appears white with a smooth surface. This finish can get worn out with time and develop cracks, black stains, rust stains, etc. The marblesheen finish can also become soft or even detach completely from the concrete surface. In such cases, epotec paint is suitable for upgrading the swimming pool.

Pebblecrete is a mixture of selected pebbles and cement. It is also used for concrete swimming pool finishing. Damaged or worn out pebblecrete finishing can also be upgraded using epotec epoxy paint coating.

Thus, epotec is an efficient waterproof concrete swimming pool coating Sydney for all kinds of concrete swimming pools.

Fiberglass swimming pools- Fiberglass swimming pools feature an outer fiberglass shell made of fiberglass strands and resin and an inner surface with a finish called gel coat. Gel coat becomes non functional if it is damaged or worn out. Consequently, water starts leaking into the underlying structures of the swimming pool causing significant damage to the fiberglass shell. Epotec paint coating can be used to upgrade the damaged gel coat and restore the waterproofing function.

Fiberglass lined concrete swimming pools can also be waterproofed using epotec paint when the fiberglass lining breaks away or becomes weak due to a number of causes.



Thus, epotec is available for pool owners for waterproofing irrespective of the type of swimming pool they may own.

All about epotec pool paint for swimming pool waterproofing

Inner walls of a swimming pool should be coated with an agent which not only provides long term waterproofing, but also withstands all types of chemicals commonly added in swimming pool water. Furthermore, the waterproofing agent must also have a smooth surface and should be easy to clean. All these characteristics and more are found in epotec pool paint. This is a pool grade epoxy pool paint which has been specifically manufactured to remain immersed in water without breaking up. Epotec expoxy pool paint is available with specialist epoxy paint suppliers Sydney. Epotec is long lasting and its performance is closely related to the correct method of application.


Epotec firmly attaches chemically with the concrete surface to provide waterproofing. This is crucial in concrete swimming pools since pool water cannot be allowed to reach the steel reinforcements used in the structure of a concrete swimming pool. Thus, epotec epoxy is suitable for waterproofing the inner walls during concrete swimming pool repairs Sydney. A thick coating of the paint ensures that the steel reinforcements remain protected from water at all times thereby eliminating any risk of structural collapse.

Waterproofing action of epotec can also be utilized in fiberglass swimming pools. The gel coat of a fiberglass swimming pool is the finishing on the inner surface. The gel coat can start wearing out with time as evidenced by the appearance of brown areas and black spots. Algae growth and osmosis can also damage the gel coat. As a result, water starts getting absorbed through the gel coat into the underlying structure of the pool causing damage to the fiberglass layers. This condition can be reversed by replacing the gel coat with epoxy paint for fiberglass Sydney. Re-fiberglassing and other kinds of repairs such as gel coat repairs, osmosis repairs, pool bracing and resurfacing may be carried out before applying epotec paint.

Epotec also protects the concrete against hydrostatic water pressure. Hydrostatic pressure is created when concrete comes in direct contact with liquid. Hydrostatic pressure causes the liquid or gas molecules to move through the concrete. This is especially true in case of concretes with imperfections such as cracks, honeycombs, etc. Epotec keeps water away from the concrete mass and prevents the development of hydrostatic pressure.


Greater the applied thickness of the epotec paint more is the strength of the coating. Since there are no solvents in epotec pool paint the thickness of the cured coating is same as the applied thickness. The normal dry film thickness of epotec is 320 microns when applied using the correct methods.

Colour range

The colour of the swimming pool should either contrast or match the colour of the surroundings such as vegetation, tiles, etc. Dark colours warm the water. There are many types of epotec epoxy paint colours Sydney such as various shades of blue, black, chamois, slate grey, white and others. Since epotec tends to get yellowed with time, it is better to opt for lighter shades.
