Delamination occurs when the surface layer of an inground pool loses its bond with the gunite or concrete structure of the pool. Delamination appears as tiny bubbles or blisters on the surface of the pool that are usually white.
Over time, these minor imperfections tend to grow to be more apparent, and once they’re large enough, the surface of the pool will begin to flake off.
Pool delamination is typically the result of poor installation. If proper care isn’t taken when applying the top plaster layer of a pool, the pool may begin the process of delamination right away.
Over time, it becomes more apparent, which robs your pool of its beauty while also creating structural problems.
Unfortunately, there’s no easy fix if your pool is delaminating, and the entire surface of the pool must be scraped and resurfaced in most cases.
