Types of Plaster in the US
Plaster is a building material that is used to coat, protect, and decorate interior walls and ceilings. It can also be used to make architectural moldings like ceiling roses, cornices, and corbels. Venetian plaster is currently popular in other parts of the world. However, in the United States, where modern architecture is paving the way, other types of plaster are widely used.
Gypsum Plaster
Gypsum is a calcium sulfate dihydrate soft sulfate mineral type of plaster. It is found in nature in the form of a white rock. It is widely used in fertilizers, molds, sculptures, and plaster.
Gypsum is used as a binding material in gypsum plaster. Dry gypsum powder hardens when combined with water. This material can be used to smooth out a block, brick, or concrete surface. It comes in a ready-to-use format and does not require sand. All that is required is the addition of water. It has excellent acoustic and thermal properties.
Gypsum plaster provides a smooth interior finish and is an excellent foundation for high-quality paints and wallpapers. It can be used on both smooth and rough wall surfaces.
Unlike traditional cement mortar, gypsum plaster is simple to apply and requires less skilled labor. The surface preparation and application of gypsum plaster should be careful to avoid cracks and peeling.

Cement plaster
