Pool plaster or marcite (also called white coat) is a kind of interior surface for a pool. The key ingredients in marcite are water, white cement, marble dust, and additives to make it smooth.
The terms “marcite” and “plaster” are often used interchangeably. The term plaster is often used to refer to any form of interior pool finish, such as quartz or pebble.
Specialty tradesmen apply the wet material over the dried gunite shell. Once dry, the layer of plaster performs the critical job of waterproofing the pool structure. It also creates an attractive interior surface throughout the pool.
