![]() ![]() It’s helpful to note that even common white pool plaster can develop white spots and streaks that are whiter than the surrounding plaster because of increased porosity in those areas. Boyd Clark, senior materials specialist with Construction Technology Labs, it’s the same reason that a head of foam is lighter than the beer the foam is lighter in color because it throws off more light: “The fact that we have a spot, or a lightened area is due to the fact you have an increased porosity,” he says. And when porosity develops and increases (which can take several months), a whitening of color/pigmented plaster results.Ī porous surface appears lighter in color because of the way it reflects more light than a non-porous surface. When calcium dissolution occurs, it means the plaster surface is deteriorating, losing density, and becoming porous. The whitening of colored plaster can also be caused by soluble calcium ions in the plaster dissolving and fleeing the scene into the pool water due to poor plaster workmanship and which has nothing to do with water balance. Here’s the workmanship issue that is both common and regrettably overlooked. But when there’s no scale there to remove, that will only cause etching, it won’t fix the problem and will shorten the life of the plaster. Once you make that misdiagnosis, it is then easy to mistakenly assume an acid wash is the best remedy. Because changes in color resulting from these defects are also a lighter or whitish color, it is easy to mistakenly believe that the problem is calcium scaling, and that the pool water has been out-of-balance. However, it is also common to have colored plaster (including quartz and pebble) surfaces lighten in color due to mistakes in plaster workmanship and material selection. As is widely known, calcium scale makes the surface rough and turns it white, and acid washing is often the remedy. First off, scale can be deposited onto pigmented plaster surfaces by out-of-balance pool water. Plaster colors can fade or turn whitish for a handful of preventable reasons. Later on, it must also be disappointing, if not more so, to learn that the cause of the unsightly color problem was misdiagnosed, and worse, the remedial action taken to resolve that problem caused more serious damage. That’s why pool owners are willing to pay extra to have that special color enhance their water and the entire backyard.īecause the interior pool surface is such a dominating visual element, it must be disappointing for everyone involved on those occasions when they watch their pigmented, colored pool become unsightly with whitish blotches, streaks, or small spots. The color adds ambiance to the setting and can make the water wonderfully attractive and inviting.
