Early on all pools featured a white plaster which showed every spot and bit of litter that accumulated on the bottom of the pool. It also only had a 5 to 15 year longevity. However, as pools evolved into much more elaborate systems with water features etc, new products were developed to make these special effects look better and more importantly reduce maintenance.
A traditional plaster finish is the least durable of pool finishes and will require re-plastering every 8 to 12 years.
Sometimes called whitecoat or marcite, basic plaster is the least expensive pool finish and many people prefer the way the smooth surface of plaster feels on their feet.
It is important to realize that when selecting a plaster color you are actually selecting a water color. Light plasters produce a sparkling, tropical water color, while darker plasters produce a deeper blue, similar to a natural lake.
