Gypsum plaster is white cementing material, which is produced by partial or complete dehydration of the mineral gypsum, generally with special retarders or hardeners added.
It is applied in a plastic state (with water) to the surface, where it sets and hardens by chemical recombination of the gypsum with water. It can be applied over the brick, block, or concrete surface to form a smooth surface.
The core ingredient of all gypsum plasters is gypsum rock–hydrous calcium sulfate–which has a water content of about 20% in chemical combination. During processing, about 3/4 of this chemically combined water is removed from the gypsum rock employing a controlled heating process called calcination.
When water is added at the time of application, the material sets and hardens, returning to its original chemical composition.
