Plaster is a building material used for the protective or decorative coating of walls and ceilings and for molding and casting decorative elements.

The most common types of plaster/Powder mainly contain either gypsum, lime, or cement but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens.

Plaster/Powder can be relatively easily worked with metal tools or even sandpaper, and can be molded, either on site or to make pre-formed sections, which are put in place with adhesive. Plaster/Powder is not a strong material; it is suitable for finishing, rather than load-bearing, and when thickly applied for decoration may require a hidden supporting framework, usually in metal.

Forms of plaster have several other uses. In medicine plaster orthopedic casts are still often used for supporting set broken bones. In dentistry plaster is used to make dental impressions. Various types of models and molds are made with plaster. In art, lime plaster is the traditional matrix for fresco painting.
