Ecodur 201: Pool Deck Coating Case Study

IMG_20170818_120255326_HDR_sm
There are 10.4 million residential and 309,000 public swimming pools in the United States, reports the Association of Pool & Spa Professionals (APSP), and about 1.18 million residential swimming pools in California, according to Metrostudy.

In Europe, leading pool-using countries are France with 1.4 million pools, Spain with 1.112 million and Germany with 800,000. The UK trails with just 230,000. The Czech Republic has twice as many pools per head of population compared to Germany largely because pools became a major social status symbol after the fall of communism.

But, all pools have one thing in common: they require a high level of maintenance to preserve not only their looks but also a safe level of hygiene, especially those open to the public. This case study concerns a private pool in Colorado where the prime consideration was an aesthetic one.

Problem
Pools may look benign, but the chemical additives, usually containing chlorine, are tough on the very fabric of the pool as well as equipment such as lightweight aluminium suction poles and even the very fabric of bathing costumes.

In this case study, in Colorado, the most critical consideration was creating a high level of finish while using a material that could not only look good, but also stand up to the invasive and corrosive effects of chlorinated water.

Solution
Castagra’s Ecodur is a benign and highly robust product resulting from the plasticizing of renewable castor oil with its complex fatty acids and the naturally occurring mineral gypsum. It is free of Volatile Organic Compounds, Bisphenol-A free, solvent-free, and completely non-toxic.

But, for the purposes of use in a highly chemical environment, Ecodur’s track record in the fracking industry where it is a lining coating for many hundreds of oil and production water tanks, demonstrates its resistance to a wide range of harsh chemicals. Furthermore, 20-year plus brine tests where no measurable deterioration has been recorded whatsoever, makes it an ideal coating for saltwater pools too.
Ecodur has, on average, double the adhesion strength of conventional epoxy coatings and it permanently retains an important degree of flexibility. This is significant for two reasons: firstly, it means it won’t crack should the concrete base suffer micro-cracks from subsidence or impacts. Secondly, its very high adhesion means that materials added for anti-slip reasons such as quartz are retained providing maximum protection for pools users on wet surfaces.

Ecodur is also highly resistant to physical degradation from UV radiation. UV is capable of quickly weakening many materials.

Application Results
Normal preparation was carried out on all surfaces that were being coated with Ecodur. They were dust free and completely dry. This is especially important in cases where the work is being carried out adjacent to a filled pool as even the smallest droplets from splashes can potentially be missed and prove detrimental.

The applicator, Ken Messer, reported his Doan Pool Project, had met expectations for ease of application and that the client was very pleased with the result, especially for having a green product used with no VOCs or solvents.
