The problems with plaster finishes

Back in the 1980s, due to environmental regulations pool contractors had to switch from using rubber-based paint finishes to plaster finishes for concrete (gunite or shotcrete) pools.  However, there are a number of problems with plaster pool finishes, including:
The plaster can be damaged if the pool water chemistry is out of balance, causing stains, streaks, erosion, and cracks.
Tiny cracks in the plaster can allow algae to grow, which can be difficult to eliminate using pool chemicals.
Unsightly rust stains on the plaster can be caused by anything containing iron, from fertilizer that blows into the pool, rebar bleeding through the plaster, to any metal objects that come into contact with the pool.
Even in a well-maintained pool, the plaster finish will have to be replaced after only 7-10 years.
How aquaBRIGHT™ is different
The aquaBRIGHT™ finish eliminates all of these issues. It is chemical resistant and pH neutral, meaning it won’t counter-balance the chemicals you add to your swimming pool. It doesn’t crack as plaster does, so algae can’t easily grow on it. And it doesn’t get stained or pitted like plaster finishes, either.
Other benefits of aquaBRIGHT™ include:
You don’t pay extra for premium colors, as is common with plaster finishes.
Compared to masonry finishes, aquaBRIGHT™ has a more uniform color.
Because there is no cure time with aquaBRIGHT™, there is no need to immediately fill a pool with water after finishing (and thus no need to pay for trucked-in water).
With aquaBRIGHT™, there is no complicated “hot start” process lasting up to two weeks for colored finishes (as is typical for masonry finishes).

Solution for Fiberglass update


Resurfacing your old Fiberglass Pools and Spas has never been easier or less expensive than today... Thanks to EcoFinish.


Easier and cheaper

This old spillover spa was removed to be replaced by a new spa. Typically the old spa would be discarded along with its value.

Now with the revolutionary, cutting-edge aquaBright finishes, the spa can remain at the property for an on-site application or refinish for resale.



Refinish, Save Time and Money

This 20 year old Fiberglass pool no longer had the Gelcoat. Prior to aquaBright, the old pool had to be removed and replaced this was the only solution.


Chose from 9 Colors

With aquaBright, the pool surface can be refinished without spending money to remove it out of the ground and relocate. The entire resurfacing process is completed onsite.

∙ Warranty – The EcoFinish aquaBRIGHT™ Pool Finish warranty is unique to the industry. Other pool finish warranties generally require the pool owner to maintain perfect water chemistry and be able to provide proof of that perfectly maintained water over the life of the finish, or the warranty is null and void.  Cementitious finishes will deteriorate from even mildly poor water chemistry, so it is crucial to maintain a  balanced pH.  

The aquaBRIGHT™ Limited Warranty includes the following: Chemical resistance, Chalking resistance, Will inhibit the growth of mildew on the surface, Crack resistance, Spall and delamination resistance, Stain  (organic) resistance. (See for the full warranty) 

∙ pH neutral surface – Simply put, unlike plaster or other cementitious surfaces, aquaBRIGHT™ is inert and does not react with the water chemistry. Any chemicals added to the water in a pool finished with aquaBRIGHT™ are adjusting the chemistry of the water, and only the water.  

A 1991 scientific research report published by the School of Building Construction at the University of Florida  stated “The deterioration of marcite (plaster) has been found to be chemically related and due primarily to  leaching of Calcium hydroxide (portlandite) from localized areas of pool plaster. Acidic pool water (pH less  than 7.0) can wreak havoc on marcite and pool plumbing, resulting in etching and staining. Proposed  solutions to control the damage aggressive water can produce include (1) paying careful attention to water  chemistry to avoid unbalanced water conditions and (2) providing a chemically inert barrier between the  pool water and the marcite surface.”  

In 1991 there was no such barrier solution… Now there’s aquaBRIGHT™. 

∙ Use less chemicals – Since there is no chemical reaction between the water and the cementitious surfaces  causing a constant shift in pH, a pool coated with aquaBRIGHT™ will use less chemicals. Commercial pool  owners have reported up to a 40% savings in annual chemical consumption for the same pool now finished  with aquaBRIGHT™. 

∙ Easy Chemistry – The target chemical balance for a pool finished in aquaBRIGHT™ is basically the same as a  vinyl liner pool. Pool owners will find it very easy to maintain the proper pH and chlorine levels as the major  cause of pH drift has been eliminated. Even the job of adding chemicals is easier, since now there is no  reason to pre-dilute the acid by mixing with water prior to pouring into the pool.

∙ Chemical resistant - aquaBRIGHT™ is manufactured from resin in the same base polymer family as the jugs  storing pool chemicals. It is approved for installation in swimming pools and spas heated up to 104° F, and is  resistant to blistering, chalking, peeling, cracking, and other signs of deterioration in normal use.  

∙ Stain resistant – aquaBRIGHT™ material is manufactured and processed into a fine powder that is applied by  the EcoFinish thermal process. As the powder particles pass through the flame, they are heated and  softened so that when they strike the pool's surface they immediately adhere and flatten out onto the  existing pool surface. As the process continues to apply material, the particles melt, flatten out, and join  other melted particles to flow together to form a complete layer. There are no pores for algae, calcium, rust,  or other staining agents to grab or imbed into. Most discoloration that would normally be a permanent stain  in a plaster pool should easily brush off of aquaBRIGHT™. 

The worst case of potential staining in EcoFinish history so far occurred due to severe abuse of a winterized  pool in the Northeast, and it truly tested the stain resistance of aquaBRIGHT™. The owner purchased a new  winter pool cover, but it was delivered and installed in the wrong color. The supplier sent a person to install  

a different cover after several months of the existing cover collecting rainwater, leaves and other debris.  The person doing the installation did not pump out and clean the debris from the existing cover, but rather  just slid the cover off and let all the biological soup sitting on top drop into the pool water. He then installed  the new cover and the pool remained winterized for the next three months. When it was opened in the  spring, the pool was found to be full of a nasty brown mess so thick that the bottom was not visible. After  three days of work to clear the water, it became apparent that the entire aquaBRIGHT surface from the  waterline down had a brown tinge that brushing would not remove. EcoFinish advised the use of Ascorbic  Acid powder (vitamin C) poured down the walls. Within just a few minutes the aquaBRIGHT™ finish was  clean and back to its original brilliant appearance throughout the pool. 

∙ Crack Resistance - aquaBRIGHT™ pool finish is an incredibly strong, yet very flexible polymeric material. It  remains flexible, although at a lesser degree, even at very cold temperatures. Results of testing conducted  over a Canadian winter in Ontario, with temperatures reaching 40 degrees below zero showed no  detrimental effects to the aquaBRIGHT™ finish applied to two steel pool wall panels that were bolted  together. No cracking was observed, even over the joined seam of the panels.  

During installation, small craze cracks in an existing pool finish will be covered by the aquaBRIGHT™ finish.  Larger cracks, including structural cracking are repaired by industry accepted methods such as epoxy  injection, hydraulic cement, and/or staples, and then coated over during the normal aquaBRIGHT™  installation. Due to the flexibility of the finish, minor cracks which may continue to form should remain  hidden below as the aquaBRIGHT™ stretches over the top. Cracks that do appear through aquaBRIGHT™  represent potentially serious structural issues, and may require that major repairs be completed on the pool.  However, it will be much easier to repair and match aquaBRIGHT™ following the repairs than other finishes.

∙ Color Uniformity – The aquaBRIGHT™ installation process yields a very uniform color and pattern over the  entire interior surface of the pool. The final appearance of the finish following installation is how it will look  for many years to come. Even the darkest colors of aquaBRIGHT™ will not mottle. Unlike cementitious  materials with dyes added during mixing prior to installation, aquaBRIGHT™ pigments are encapsulated in  the polymer resin during the manufacturing process, and therefore are protected from the pool chemistry.  Dyes that give plaster and other cementitious finishes their color are continuously exposed to pool water  chemistry on and below the surface, and the result can be a non-uniform color change that appears as  patches or blotches of bleached out color. This is called mottling, and usually occurs over time, but has also  become apparent almost immediately following the new finish start-up process. It is generally more  prevalent and easier to distinguish with the darker dyed finishes. 

∙ Scale Resistance – Scale build-up on a pool’s surface is usually attributed to two factors; free calcium  suspended in the water which attaches itself to the pool finish, or calcium leaching down onto the pool finish  from water or rock features above the waterline. Water chemistry again plays a critical role in scaling due to  free calcium, as a high pH will actually cause the free calcium to become chemically attracted to the  cementitious finish. Regardless of the method of build-up, once deposited onto a cementitious finish the  scale becomes chemically and physically bonded with the surface. Since the scale and the finish are both  calcium based, they join and become one. Removal of the scale is only accomplished by acid washing the  pool to chemically burn the calcium from the surface, which also removes some of the finish as well. Care  must be taken not to over expose the finish to the acid, or too much of the finish will be removed leaving a  rough gritty feeling surface. 

The aquaBRIGHT™ surface is neither chemically attractive to calcium, nor does it present a porous physical  surface onto which calcium can adhere. Calcium that may have leached down onto the surface from a water  feature is not well adhered, and can either be picked off, or removed using a “stain erasure” on the end of a  brush handle. 

∙ Chip, Flake, Peel, Chalk Resistance - aquaBRIGHT™ is manufactured using a polymeric resin that is  engineered to withstand exterior exposure for many years without any breakdown in chemical structure.  Unlike vinyl and fiberglass materials, the base polymer family has been used for decades to provide  outstanding performance in exterior applications where the other materials eventually show signs of  degradation. Because it remains a soft, flexible material throughout its life, it is extremely resistant to  chipping, flaking and peeling and should remain a single cohesive polymeric layer that remains well bonded  to the pool surface. 

∙ Fade Resistance – In addition to using only exterior grade colored pigments, aquaBRIGHT™ is formulated to  provide outstanding U.V. protection and color stability. Real world pool environment testing ranging from  the frozen north to very hot desert climates has shown the aquaBRIGHT™ finish to be fade resistant.  Additionally, outstanding results from long duration QUV Accelerated Weathering Testing confirms the  ability of aquaBRIGHT™ to withstand the effects of exposure to U.V. sunlight. We are confident that an  aquaBRIGHT™ color finish applied to a pool’s surface should look vibrant and colorful for many years to  come.

∙ Soft and easy on the feet – aquaBRIGHT™ was intentionally engineered to be a soft feeling material. The  surface can best be described as an “orange peel” texture, which provides a pleasant feel for swimmer’s feet. Cementitious finishes such as plaster and quartz may begin as smooth finishes, but will degrade over  time into rough finishes that can be very abrasive on feet. Pebble finishes, even polished stone versions are  never really easy on the feet due to their bumpy surface. 

∙ Slip Resistance – All current use pool surfaces are naturally slip resistant, with the exception of fiberglass,  which tends to feel very slippery, especially on sloped depth transitions. aquaBRIGHT™ pool finish, with its  orange peel surface is inherently slip resistant as normally applied for pool surfaces. On step treads, bench  tops, and beach entries the finish can be applied as a way to increase that slip resistance to very safe  levels. Following an application at a SeaWorld water park facility, the finish was tested by SeaWorld Health,  Safety, and Environmental Engineering to determine if the slip resistance (coefficient of friction) met their  standard. Utilizing specialized equipment, the finish was tested in the wet condition with the minimum  acceptable slip resistance being equal to that of a wet concrete surface. aquaBRIGHT™ was measured to be  two full points (on their standard scale) over the minimum standard, and was deemed to be very safe for  their patrons. 

∙ Outstanding Adhesion – Cementitious pool finishes do not provide an impermeable, waterproof surface, and  for all the unbalanced water chemistry reasons previously discussed may degrade not only on the surface  but also on its interior. Over time, delamination within a plaster surface can begin to form so that instead of  one thick layer as it was originally applied, the layer has split into two layers one on the other. Water begins  to fill this layer, and forms “hollow spots”. These may be seen as bulges in the pool's surface as they begin,  but left unrepaired, will eventually break out the top layer of plaster leaving a distinct missing plaster area on  the pool surface. Pebble finishes have a much lower risk of this type of delamination, but as the pebbles are  adhered to the surface in a cementitious mortar matrix, it too is subject to poor water chemistry  degradation. aquaBRIGHT™ is an impermeable, waterproof surface and can provide the barrier required to  protect the cementitious base material from degradation due to poor water chemistry. The bond strength of  aquaBRIGHT™ to an existing plaster finish has been tested at over 800 psi. And when the surface finally did  release, a cone-shaped plug of plaster an inch thick popped out with the aquaBRIGHT™ still attached. 

∙ New Finish Start Up – With a new aquaBRIGHT™ finish, there is literally nothing to do except “Balance and  Swim”. Just fill the pool, balance the water chemistry, and swim in crystal clear water. Pools and spas may  even be heated immediately after filling. All other cementitious pool finishes require some type of start up process and wait to heat time period. These range from continuous brushing and backwashing to clear the  suspended plaster chalk from the water, to “hot starts” requiring acid washing and chemical additives to  

expose aggregates and create the desired appearance of the finishes. These startup processes are  absolutely critical to the final appearance and longevity of the cementitious finish, and may take a week or  more to complete. If they are done improperly, or neglected even to a slight degree, the finish will be  affected. Regardless of who performs the start up, the final outcome will determine the appearance and  longevity of the surface (mottling, bleaching, over/under exposed), and the pool owner still cannot use their  completed pool for over a week.

∙ Repairable – Damage happens. Whether it occurs from natural causes or human causes, damage to a pool’s  surface can happen. These imperfections can range from minor craze cracking, chipping, and abrasions, to  delamination, gouges, and structural cracks. Due to the difficulty of repairing a cementitious pool finish,  these conditions usually remain unrepaired until it’s time for a complete remodel or resurfacing.  aquaBRIGHT™ applied over cementitious or fiberglass surfaces will assist with hiding minor imperfections  that may develop in the base surfaces. If however, a pool finished with aquaBRIGHT™ were ever to need  repair it can easily be accomplished. Minor cosmetic damage is repaired by reheating and melting the  material to heal gouges and cuts, and to restore the glossy finish. Major repairs to the pool’s underlying shell  would only require the aquaBRIGHT™ finish to be cut back approximately two inches around the damaged  area being repaired. Following the structural repair the aquaBRIGHT™ surface is reapplied over the repaired  area, and blended with the surrounding finish utilizing EcoFinish equipment. 

∙ Water Slide Finish – Although aquaBRIGHT™ in its standard application has a naturally slip resistant property  which can be enhanced to provide outstanding slip resistance for steps, it can also be applied to concrete  and fiberglass water slides to create a slippery slide surface. Now waterslides can receive a finish that  matches the interior of the pool. Normally, cement water slides require an acrylic sealer or paint to be  applied to create the slippery surface which typically only lasts from one to two years. Fiberglass slides  exposed to the sun begin to chalk and become less slippery. aquaBRIGHT™ will retain its color and  appearance for many years, and if it were to become less glossy and slippery from all the sliding wear, it can  easily be re-glossed or even have additional material added without the need to remove the existing  aquaBRIGHT™.  

∙ Use Above the Waterline – Unlike cementitious pool finishes, aquaBRIGHT™ may be used on areas above  the waterline and remain resistant to cracking or fading. aquaBRIGHT™ is suitable for always wet,  sometimes wet, and never wet applications on the pool surfaces and its features. Pool tile can now be  eliminated by applying the aquaBRIGHT™ finish up to the coping. Vanishing edges and the backside of  vanishing edges can now be finished with aquaBRIGHT™ to provide a matching finish throughout. Exposed  bond beams that are never wet are also candidates for a matching aquaBRIGHT™ surface. 

∙ Choice of Colors - aquaBRIGHT™ comes in eleven different colors ranging from commercial pool white tones  to very dark blues and blacks. All aquaBRIGHT™ colors are a blend of different colors that create speckled  finishes in variations of white, brown, blue or grey/black tones that resemble a granite surface when applied.  EcoFinish responds to customer requests with new color offering, such as the spring 2014 launch of our two  newest colors Midnight Blue and Perle Noire  

∙ Custom Colors – Cementitious pool finishes may be varied with dyes to change the entire surface color of  the pool, for only that one color. Pebble finishes can utilize different naturally occurring colors of pebbles to  create subtle, more subdued shade variations of the pool finish. With EcoFinish’s custom color service you  can now have aquaBRIGHT™ made to your order in virtually any color you desire. Just as with interior design  choices where material pattern colors are intentionally highlighted throughout a room, now pool designers  can choose to accentuate a color or colors in the design scheme for the entire pool, its features, and the  surrounding hardscape. Custom colors are available as custom blends with a specifically varied shade/tone,  or all the way to wild solid colors found in waterparks and kid’s splash pads. Colors may be matched from a  physical sample, a color swatch, or RAL color code provided by the customer.

∙ Eco Friendly Finish – EcoFinish aquaBRIGHT™ Pool Finish has many attributes that make it a Green, Eco  Friendly product: 

1. It requires less energy resources to manufacture as compared to cementitious materials. 2. It requires less energy resources to transport than cementitious materials. A typical pool requires  around 100 lbs of aquaBRIGHT™ material to be shipped, not tonnage as with cementitious finishes. 3. It requires far less energy resources to install the finish. 

4. It will outlast the cementitious finishes and will therefore reduce/eliminate the energy expenditure to  remove the old finish, manufacture new material, and install a replacement cementitious finish  several times over the life of the pool. 

5. It requires fewer chemicals over the life of the pool to maintain balanced water chemistry, thereby  requiring fewer chemicals to be manufactured, and reducing the chemical exposure of the customer’s  backyard. 

6. It provides a barrier for the pool interior, reducing water loss experienced through cracked  cementitious finishes. 

7. Although EcoFinish does not incorporate recycled materials into the aquaBRIGHT™ product due to  strict manufacturing purity requirements, the aquaBRIGHT™ material is considered recyclable should  it ever be physically removed from the pool. 

8. Stored properly, aquaBRIGHT™ powder has an indefinite useful lifetime, and should never require  disposing to a landfill. 

9. There is no end-of-job leftover waste to be disposed of in landfills, as is with every cementitious finish  which can be as much as hundreds of pounds.
