Triple A Pools offers marble dust in four different shades and color quartz in twelve different colors. Marble dust is a mixture of white cement and marble dust aggregate that is expertly applied by hand for a smooth troweled finish, approximately 3/8ths to half an inch thick. Marble dust will last ten to fifteen years before it requires another marble dusting. Marble dust is offered in White, light gray, medium gray, and dark gray. In order to create a colored pool you must go to an exposed color quartz finish. The color quartz finishes can be applied to your pool at an additional fee. The color quartz finish will last fifteen to twenty years.
