Dark vs. Light Pool Plaster: Heat Retention & Water Temperature

Yes, a dark-colored pool plaster absorbs and traps solar heat more efficiently than white plaster. Dark surfaces effectively convert sunlight into thermal energy, increasing water temperature. Therefore, dark plasters like black or deep blue are preferred in regions with cooler climates to prolong the outdoor swimming season. While they help maintain warmth effectively, darker plasters might result in higher water temperatures during hot summer months in warmer regions.
