QUALITY EPOXY POOL PAINT

 

Product Description of our 4-Layer epoxy system
specially designed and tested for swimming pools

The Latest Technology

Pool Solutions' four-layer epoxy pool paint system is offered in two-part epoxy resin and curing agents.  The chemical reaction makes it much more effective, tougher and long-lasting than normal paint or cement-based coatings. The special qualities of a refined epoxy are developed by the chemical reaction during the curing stage and provide thickness, abrasive resistance, chemical resistance and a hard, solid, porcelain-like finish unequaled by any other product.  

For these submerged and chemical-rich environments, some pool paint products will not last very long due to the lack of bonding strength and rapid weakening due the penetration of chemicals and water into the layer structure.  The chemical reaction of a two-part epoxy creates strong  "honeycomb-type"  molecular structures that cannot easily be penetrated and weakened by other substances.  The special qualities of our epoxy swimming pool paint are achieved by the specially selected resin and pigment compounds, further strengthened by the latest technology available in curing agents and additives.

Chemical resistance

From 2004 we took the lead by offering a newly developed and upgraded pool paint system that is immune to acid and chlorine staining. 

We tested our product by spot-wetting with undiluted acid and chlorine on dry surface with no sign of staining, even after constant surface wetting over a period of 72 hours. 

In submerged environments, any chemicals added to the swimming pool are further diluted and dispersed which further reduces the risk of staining.

 

Our latest technology takes the hassle out of pool maintenance and swimming pool repair has become a task that any handyman can undertake with our DIY Pool Paint option. Normal HTH chemicals and swimming pool acid can be added directly into the swimming pool without the risk of staining or discolouring over time.

Four Layers of Protection

Our specially developed industrial concrete primer epoxy ensures proper penetration of the surface to which it is applied and excellent adhesion to the surface up to 400psi, even penetration to a depth of 2-3 mm. The product adheres exceptionally well to marbelite, gunnite, concrete and even fibreglass shells or plastic moulds when properly sanded.

80% of the success of the product depends on the preparation of the pool surface and the bonding strength of our specialised pool paint primer.

This primer layer is left for 30min to an hour to become wet/sticky. This is important for the application of the first top-coat, which will then chemically bind or "fuse" with the primer layer. This combination layer, over the next few hours, will form a solid, hard and glossy surface.

The final two top layers are applied to ensure that a tough, gloss porcelain-like finish is achieved that will last for mnay years. This is unlike most other pool paints available, where the top layer is applied on a dry surface or on a dry primer to form a separate top layer, still leaving the risk of inter-layer de-lamination.

Bond-strength Test and Coating Thickness

Research on in-ground dams, reservoirs and pools has proven that the only way to overcome the risk of blistering due to reverse osmosis (water -pressure from outside the structure) , is to ensure that the highest bonding strength is achieved and that the the complete coating itself is thick enough to withstand moist migration through the structure. For this reason we do not formulate our product with a high content of water dilution or solvent dilution. The problem with solvents (or water dilution) is that it evaporates during the drying time, leaving only the pigment and binder elements of the paint behind. The more solvents are used in the formulation, the thinner the layer will be after drying. It is also a well-known fact in the coating industry that solvents reduce the inherent qualities of an epoxy e.g. hardness, bonding strength, chemical resistance, UV-resistance etc. (In water-based epoxies the water is used as a solvent and will also evaporates.)

Our swimming pool primer (first coat) epoxy is not diluted by any solvents and is a 100% pure combination of binding elements. Our Topcoat layers utilizes only a 6-10% solvent content to aid towards easier application. The product is rolled on by hand, using Mohair rollers, leaving a thick resilient epoxy layer that will last for many years.

Like the primer layer, the top-coat layers are also two-part resin and catalytic hardener combinations that are smooth, tough, resistant to UV radiation and stain-resistant. Algae cannot adhere to the glossy surface. The protective coating is available in white, shades of blue, charcoal and black.

UV-Resistance and weather-ability

Our formulation utilizes the highest UV resistant Rutile Titanium Dioxide white base pigments, high quality liquid colourants and a specialised curing agent to ensures that chalking of the swimming pool paint due to chemical and UV-exposure is effectively minimized. This will prolong the life-expectancy of the product more than three times compared to conventional additives we have found in many commercially available swimming pool paints. In fact, investigating the formulations of three different commercially available swimming pool epoxies, we have found them all to be using a common white base pigment intended for indoor use and no UV-resistant additives!

Chalking occurs on all paints and epoxies, especially on outside structures over long periods of time due to the combination of chemicals, and UV-radiation. Chalking is the process whereby the pigments in the coating will reflect the light rays into the adjacent binding elements of the layer. The heat and energy released into these particles will slowly break down the bonding structure, loosening the pigment particles which are then released into the water. Water balance (Alkalinity, pH and Total Hardness) also plays an important role determining the lifespan of the product. This can be seen when the swimming pool has not been used for a long time and wiping with the hand on the surface, a milky substance is released. Chalking occurs mostly on the steps and the top 500mm area of the walls.

UV Tests on pool paint

In this photo, the difference between the two top panels and the two bottom panels clearly shows the difference in colour stability performance between two different types of curing agents used in the same formulation. These results were obtained after these four panels were subjected to 500 hours of laboratory UV exposure and moist simulation tests.

 

It is therefore essential that UV-absorbing pigments, UV-resistive ingredients and specialized curing agents be used in these type of swimming pool paint formulations. With our latest upgrade during 2017 we have reduced the effect of UV radiation even further to the level where our coatings will not form visible chalking under correctly-maintained swimming pool conditions.

Epoxy Formulations

Our Primer formulation was specially developed for submerged concrete, marble plaster and cement type surfaces, but is also very effective on fiberglass and most other materials. Together with our chemical resistant top layer, the system consists of two different epoxy resin and hardener combinations. (Unlike many available pool paint systems consisting of thinned-down versions of their top-coat as a penetrating primer, or not utilizing a primer at all). Many pool paints and epoxy systems are advertised as a self-priming top-coat product. The fact is; any top-coat epoxy naturally offers good bond strength. The problem with tjis approach is:

1. You require a low-viscosity liquid to deeply penetrate the large variety of possible substrates.

2. You require a high viscosity and thicker top-coat that will result in a thicker coating to offer a long lifespan.

Both of these atributes cannot be achieved in a "one-coating-for-all type solution". A compromise between penetratiion depth and lifespan of the top-coat must be made.

Our primer was specially formulated using selected industrial-grade products that are specifically developed to offer maximum bonding strength and penetration into cement, concrete and marble plaster, as well as it's resistance to water (to be able to seal the pool from outside moist and prevent blistering).

Our formulations are high-solid formulations that are not diluted by high levels of solvents (which will reduce the special qualities of any epoxy).

The Top-coat epoxy provides qualities like chemical resistance, gloss, water resistance and colour stability. Of course there are several ingredients added to the basic resin and curing agent combinations to enhance or add certain qualities e.g. anti-sagging agents to prevent that the epoxy layer becomes thin at the top of the wall and thick at the bottom, also products that will enhance flexibility, self-leveling products for smoothness, enhancers for chemical resistance and a large quantity of quarts to provide abrasive resistance and long-lasting gloss etc.

Note that these Epoxy formulations are not the same as normal paint products which are single component systems (not resin and curing agent combinations). Normal paints rely on the evaporation of solvents into the air to dry. Normal paints does not offer the bonding, toughness, chemical resistance etc. to the level that epoxies can offer.

Most of an epoxy's qualities (80%) are resident in the curing agent part being used. The main feature is that the curing process is a chemical-reaction-driven process where very strong and impenetrable honeycomb-type molecular structures are formed.

Key benefits

Algae resistant - no algae that can cause stains and pitting, will grow on the pool surface anymore.

Chemical resistant to acid, salts, chlorine and UV-radiation, your pool will look new and sparkling clean for many years to come.

Less maintenance due to the elimination of algae growing into the marble plaster, you don't need to scrub with strong chemicals anymore, also reducing the need for shock treatments. The application of an epoxy coat can reduced the use of chemicals by as much as 60%.

Less expensive than to re-marble plaster and much less expensive than fiberglass linings.

Excellent bonding to marble plaster, cement plaster and concrete.  Our specially developed epoxy undercoat will penetrate the marble plaster or cement surface to a depth of up to 2 to 3 millimeters.

The combination of primer and topcoat will harden to a tough and durable gloss finish over the next 3 days. Further hardening occurs after water is added to the pool for a long-lasting, quality finish. The product can be used on fiberglass. In fact the swimming pool that we have coated in 1997 is a fiberglass pool and was still in use with the original epoxy coat when we revisited in 2008 .

QUALITY

Quality is one of the most important aspects in this market known for its pitfalls, watered-down products and fly-by-nights. We reference you to our previous customers on our home page, some with contact details listed by permission. Our track record can be verified by independent ratings and testimonies published on Hellopeter.com

We have tested a number of available epoxies advertised for swimming pools, just to find that very few of these epoxies can survive the harsh chemical and damp conditions of submerged pool surfaces. Therefore we have developed product combinations and methods that are unique and specially designed for swimming pools.

The main problems we found with some epoxies are:

Weak bonding with and/or penetration into the base materials due to inferior primer coat qualities, resulting in peeling, blistering, cracks etc.

Discoloring (yellowing) due to pigment ionization, UV radiation or untested/inferior ingredients.

Blistering due to dampness from high water tables building up pressure from outside the pool and behind the coating.

Staining due to weak resistance to water and chemical penetration.

Contamination and damage due to long drying times and weak water-spot resistance especially during the rainy season.

Chalking, the process whereby the coating is releasing its binder elements and powders into the swimming pool water, effectively loosing thickness, bond-strength and overall deteriorating the coating due to chemical wash and UV exposure.

 

How did we overcome these challenges?

First, we made sure our tough and durable primer is specially developed and can be applied under adverse conditions.

Secondly we ensured that this primer penetrates and pentrates into the substrate material up to a depth of 2 - 3mm. The result is a durable, tough, plastic-like bottom layer. 90% Of problems with paint or epoxy coatings are due to improper preparation of the surface and cheap (or no) primers.

We apply a strong epoxy concrete Primer and three Topcoat layers to strengthen the coating against reverse-osmotic pressure. In 90% of cases, the problem can be overcome by proper pre-inspection for the presence of water behind the marblite plaster and if detected, the implementation of an additional water barrier treatment (PCT56) if necessary. Reverse osmotic pressure is a condition that can occur on underground structures due to underground water tables and water accumulation against the pool sides. Water may penetrate through the concrete layer from the outside of the pool. On most older marblite plastered pools this is not a common problem except where the pool is situated against a hill side, flower boxes against and around the pool and or heavily soaked garden soil due to heavy irrigation. Evaluation of the surroundings and pre-inspection as described in our installation instructions is a must on all swimming pools.

On newly built structures we strongly advise the use of a proper bonding liquid in the plaster cement (for cement plastered swimming pools e.g. Sika WM200) as well as the use of a water barrier treatment (PCT56) as a precaution against moist penetration from the outside. See our installation instructions and DIY videos for more details regarding pre-inspection and the use of PCT56 Water Barrier where reverse osmotic water flow might pose a ris

We have also developed our epoxy products to offer as low as three-hour water-spot resistance during summer time conditions. We have selected ingredients that improves water-spot resistance. Visit our section on tests to see how we tested our products against chemicals and also water-spot resistance.

Our tested, durable and tough top-coat epoxy comes in gloss white, light blue, coral blue, midnight blue, charcoal or black. The topcoat is applied on the primer coat while the primer is still sticky, ensuring complete bonding and chemical reaction between the layers. A final decorative gloss top-coat is finally applied. Once set, this combined four-layer epoxy coat forms a solid and durable covering that has penetrated the pool surface.

We are constantly testing new technology in raw materials and will continually replace older technology with newer technology as per manufacturer's specifications and extensive test results. We will then test new formulations by our own methods unique to this market with sunlight, chlorine and acid to prove the higher expected quality.

New Developments and Tests

At Pool Solutions we are constantly developing and researching new technology. The chemical industry is constantly developing new and better epoxy resins, additives and curing agents. That is why during 2004 we have again upgraded and vigorously tested our formulations to profit form these latest developments. In Nov 2007 we have again upgraded our product to utilize the latest in UV-resistant Titanium Dioxide white pigment and liquid colourants. During 2017 we introduced new curing agent technology for imporved UV- and chalking resistance. Our initial main goals for developing our product were the following:

To develop a primer-coat that is capable to adhere better to new concrete and cement-plastered structures as well as existing marble plaster surfaces. We also tested its bonding on sanded fiberglass with excellent results.

To develop a top-coat epoxy that offers excellent waterspot resistance. This was necessary to overcome application problems during rainy seasons when rain could contaminate, discolor and ruin our final coat within three hours after application.

To develop a top-coat epoxy that is immune to acid and chlorine to the extend that normal swimming pool chemicals can be added directly to the pool without special precautions and without the risk of permanently discoloring the top layer. See our recommended chemicals on the FAQ page.

The Results

Our primer coat penetrates the substrate and will form an excellent, tough, plastic type bonding layer that will never laminates from the surface, completely sealing the pool surface. To ensure the highest possible qualities, we have always followed the route of specially developed Primer and Top-coats, each coat uniquely offering the best qualities for the specific application need

Our top-coat offers better gloss and UV-resistance. It offers high colours stability and stain-resistance against water or chemicals. Excellent water-spot resistance offers applicators the ability to apply the top-coat with much less risk, even on rainy days. On warm days (25-30 deg C) water spot resistance is reached within 3 hours. Should it then rain, no damage to the gloss and/or color will occur. The pool in the photograph below was finished at 12H30 on a warm day in Nov 2004.

A thundershower started at 15H30 while the application team was still nearby. Due to past experiences with epoxies from other suppliers, they rushed back to the pool, expecting a ruined top-coat. They cleaned and dried the pool and found that there were no signs of damage to the gloss coat. It rained again heavily at 19H00 that evening, washing dirt and red garden soil into the pool during the night. The next day at 12H00 we arrived to have a look and was shocked by the red muddy pools of water, leaves and dirt that has accumulated in the deep end and on the steps.

Normally, this would have meant staining of the top-coat due to the red muddy water and residue from the leaves before final setting of the compound qualities. We expected ring-mark contamination because of the time the dirty water was left standing on the newly-applied top coat.

We cleaned and dried the pool. Our new topcoat formulation was a winner! We were pleasantly surprised to find that the pool was completely and beautifully protected by the new epoxy formulation. The photograph below shows the steps shortly after cleaning where pools of red muddy water and leaves accumulated overnight.

Some of the problems common to older or cheaper type epoxies are listed below: (please note that most of these problems will also be present if a normal paint product is used to coat submerged and chemically rich surfaces):

  • Poor water absorbtion resistance

  • Long curing times

  • Very weak water spot resistance (when applying the product during rainy seasons or high humidity conditions that could cause staining, discoloring or loss of gloss)

  • Staining by chemicals (acids and chlorine) added directly to the pool

  • Chalking due to low UV resistance causing the breaking-up of the binder elements in the coating structure, causing slow disintegration of the layer

  • Fading and yellowing due to low UV resistance

  • Water absorption weakening the abrasive resistance and bonding strength of the layer, resulting in blistering and/or peeling etc.

MORE TESTS

The photographs below show four different epoxy coatings tested to determine it's resistance against staining by undiluted acid and chlorine. Undiluted Hydrochloric acid and HTH dry-chlorine were used to perform simultaneous tests on all four epoxy coatings as shown below. Cotton balls were used to keep the spots wet over a period of 72 hours. Separate cotton balls were saturated with acid and over-saturated water/chlorine mix.

   

Four panels were coated with different epoxy coatings according to the suppliers instructions and left for seven days to cure before testing.

The test panels were left under test for 72 hours. The photographs below show the results.

Product 1 & 2 (From Competitors)

 

After only 24 hours the products from two manufacturers seem to be stained by the undiluted acid and chlorine tests.  The yellow-brown stains could not be removed without damaging the layer which indicates that the coatings have absorbed the chemicals into the layer itself.  These products also lost it's gloss and yellowing appeared after a few months.  Chlorine tests left a lighter yellow mark than the acid. The products were easily stained by acid and to some degree by chlorine.

Another observation was the high rate of chalking on pools previously coated with these products.   We suspect both these manufacturers use the same basic formulation.  Chalking is the release of high concentration of pigment into the water causing a milky appearance in the pool.  This is especially visible during- or after winter months when the pool wasn't used for a period of time.  The result is that the layer will thin-out very quickly.

The expected lifetime of these coatings are estimated between 6 months to 2 years. Adding chemicals directly into the pool will stain these layers over a short period of time.  We have experience of this as we have tested it in our own experimental swimming pool.  Both suppliers of these products does however specify in their instructions that chemicals should not be added directly to the pool but should first be diluted in water and then added through the weir while the pump is switched on.  This is an essential factor concerning their guarantees. 

These products are sold at the same price level as our own, but are definitely weakened by larger additions of solvents to the formula as well as lower priced additives, resins and curing agents that are used.   See the tests below on our previous and latest products.

Our aim is not to discredited any opposition as we believe that there are good products like our own in this market, some which we haven't tested yet.  But we must warn that clients should be careful and investigate the supplier or applicator's technical knowledge and the type of primer and at least the type of curing agents that are used in their formulations. Ask questions like: Do they have a specialized primer? Are they using the same type of basic epoxy resin and curing agent for both top coat and primer? This is not good. How do they protect the pool against reverse osmoses (water ciphering through from outside the pool)?  How many layers do they apply? If this is done by one thin primer or no primer at all - you can expect problems.  This is the one major problem coating underground structures.  If dampness is allowed from outside to reach the top layer, blistering bubbles is normally the result.  We apply one very saturated and specially developed epoxy primer coat to stop dampness from the outside.  After the pool is properly sealed, we will apply 3 chemical-resistant top coats.

Test their knowledge about their products, ask them about their developments.  A lack of technical knowledge normally indicates that no development has been done and they could be selling a standard formulation which is bought out from other applicators. It might proof to be very old technology or even diluted.  These products does not offer much improvement above any normal paint product advertised for swimming pools, in which case the objective is not the long term satisfaction of their clients but rather fast profits.

Product 3 (Pool Solutions Product 1)

This older product (before Nov 2004) from Pool Solutions showed only slight discoloring from the direct acid tests and no staining by strong chlorine could be detected.  Adding acid into the swimming pool while filled with water would not stain the product as this slight stain occurred after exposure to direct, undiluted acid over a period of 3 days. However, we have even further improved the formulation by using more expensive curing agents, additives and chemical resistant ingredients in our products.

Product 4 (Pool Solution's Latest Development)

This latest development from Pool Solutions could not be visibly stained by constant exposure to direct undiluted chemicals over a period of even 3 days.  After three days the wet acid and chlorine residue spots could be wiped of with a cloth to leave a clean and shiny white surface.  This latest development allows the user to add chemicals to the pool without special handling or special precaution when used according to manufacturers specification. 

Please note that HTH-dry chlorine was used for these tests. Other products (e.g.Waterwell dry chlorine) might stain the paint.

The hard plastic-like gloss finish proofed to be impenetrable by the chemicals.  Our latest development offers higher gloss and an impenetrable layer against approved chemicals.  Chemicals can now be added directly to the pool even in undiluted form. Follow the manufacturers instructions regarding dosages.

We have achieved the following product quality through constant development and research:

  • Excellent water resistance with no absorption into our product.  This means our product will not be weakened, softened, fading due to water absorption like normal paint products and cheaper and/or older technology epoxies.

  • We have shortened touch-dry curing times of our top-coat  to 2 hours at 25deg Celsius.  The advantage is that rain or other dirt will not damage or discolor the newly applied coat after 4 hours of drying time. Even should dirt be washed into the pool and left overnight it can be washed and cleaned the next day without staining or loss of gloss. 

  • Exceptional water spot resistance means that even if it rains on our newly applied product, even when not fully cured, the product will not be discolored or damaged. 

  • Chemical resistance.  Undiluted hydrochloric acid and chlorine were tested directly on dry surface of our product for 72 hours with no staining or absorption.  This means approved chemicals added directly into the pool will have no effect on the our epoxy coatings.

Starting out in 1997, QUALITY always was one of the most important aspects in this market known for its pitfalls and fly-by-nights.  We can reference you to our previous customers and show you pools that were coated in 1997 and still show no sign of discoloring or deterioration.

We have tested a number of available epoxies advertised for swimming pools, just to find that very few of these epoxies can survive the harsh chemical and damp conditions of some pool surfaces.  Therefore we have developed product combinations and methods that are unique and specially designed for swimming pools.
