Why Pool Coatings Peel

Ask a question hereThe Truth About Pool Coatings, Surface Preparation, and Why Failures Really HappenEveryone wants to know which pool paint is the best.Wrong question.In this episode of Talking Pools, Rudy Stankowitz takes listeners far beyond the paint can and into the science of coating failures, adhesion, compatibility, moisture, and surface preparation. Using the recent attention surrounding the Lincoln Memorial Reflecting Pool as a jumping-off point, Rudy explains why nearly every coating failure investigation asks the same question:What happened before the paint ever touched the surface?From chlorinated rubber and acrylics to epoxy and high-build epoxy systems, this episode explores the strengths, weaknesses, and proper applications of today's most common swimming pool coating systems. More importantly, it explains why even the most expensive coating in the world can't overcome poor preparation.If you've ever wondered why one painted pool lasts fifteen years while another begins peeling after a single season, this episode connects the dots between chemistry, application, environmental conditions, and good old-fashioned craftsmanship. Along the way, Rudy shares real-world stories, practical advice, and plenty of his signature Gen X humor.Whether you're a pool service professional, contractor, facility manager, or simply fascinated by how coatings succeed—or fail—this is one of the most comprehensive discussions on swimming pool coatings ever presented on the Talking Pools Podcast. In This Episode Why asking "What's the best pool paint?" is the wrong question  The lessons every pool professional can learn from the Lincoln Memorial Reflecting Pool  Why compatibility between coating systems matters  Understanding chlorinated rubber, synthetic rubber, acrylic, epoxy, and high-build epoxy coatings  Why surface preparation determines the success or failure of almost every coating system  How to properly inspect an existing painted pool before recoating  The importance of documenting coating failures before disturbing the evidence  Mechanical adhesion vs. chemical adhesion explained in plain English  Why moisture remains one of the biggest enemies of successful coating applications  Proper cleaning, sanding, acid washing, and contamination removal  How silicone contamination, chalking, oils, and residue interfere with adhesion  Why weather, humidity, dew point, and curing conditions matter  Understanding recoat windows and why missing them creates problems  Common causes of blistering, peeling, and coating delamination  Adhesive failure vs. cohesive failure vs. substrate failure  ASTM testing methods used during professional coating failure investigations  Why coating failures should be investigated—not guessed Key Takeaways✔ The most expensive coating cannot overcome poor surface preparation.✔ Compatibility between existing and new coating systems is critical.✔ Surface contamination is often invisible but can completely prevent proper adhesion.✔ Moisture inside concrete can remain long after the surface appears dry.✔ Proper environmental conditions are just as important as choosing the right coating.✔ Good investigators document the failure before removing any evidence.✔ Most coating failures begin long before the pool is filled with water.✔ Successful coating jobs are built on preparation—not luck.Memorable Quotes"Surface preparation isn't part of the job. Surface preparation is the job.""Compatibility matters. Chemistry matters. Guessing doesn't.""Painting a pool isn't hard. Knowing when not to paint—that's what separates a guy with a roller from a pool professional."Featured SponsorsBlu-Ray XLReduce chemical usage, lower labor costs, and improve profitability with Blu-Ray XL's mineral purification technology for pool professionals. Jacks MagicProfessional stain identification, removal, and prevention products trusted throughout the pool industry. AquaStar Pool ProductsLearn about AquaStar's innovative Pipeline cartridge filters featuring NSF-tested performance and simplified maintenance. Service Industry NewsStay informed with nationwide pool and spa industry news, technical articles, and the famous Horror File.
