Pool Finishes: The Technical Guide to Material Specifications

Pool finishes fail in patterns — and the patterns trace back to specifications that were ignored during application. The technical guide behind quality pool finishing exists precisely because the difference between a finish that lasts eight years and one that lasts twenty is written in the specs: mix ratios, surface preparation, application temperature, curing time, and inspection points.

The material specifications matter at every stage. The shell has to be prepared to a standard — clean, sound, and free of the laitance and debris that cause bond failures. The finish has to be applied within its environmental envelope — too hot, too cold, or too humid, and the chemistry changes. The curing phase has to be protected, because the first 30 days determine the finish's long-term durability more than the next 30 years do.

For a homeowner, this translates into one question for any contractor: what specifications are you installing to, and can I see them? The ones who can answer are the ones whose finishes make it to twenty years.
