Plaster is a common material used in buildings, in a process called lath and plaster. This process is done on the wall surfaces, where a series of wooden strips are covered with half-dried plaster and then hardened to form a surface.

The Plaster used in this process of lath-and-plaster construction is mostly Lime Plaster. The curing time for Lime Plaster is almost a month. During the curing process, small amounts of PoP are mixed into the wall putty to stabilize the lime plaster. Since Plaster of Paris tends to set fairly quick, retardants are used to slow its setting time just enough to allow workers to formulate a mixture of large amounts of wall putty.

Plaster of Paris (PoP) is a popular building construction and decoration material used for either protective purposes, or for decorative coatings on and inside the walls and ceilings. The water retention of Plaster of Paris depends on the reaction of water molecules with dehydrated or partially hydrated calcium sulfate(CaSO4) present in the plaster.

It is also used for various casting and moulding applications. In the English language, “plaster” usually means a material used for the interiors of buildings, while “render” is used to refer to a material used for outside applications. Stucco is another terminology used for this material.

Uses of Plaster of Paris

Decoration : Plaster of Paris is extensively used to create decorative pieces which simulate the appearance of metal, stone, and wood. It is extensively used to decorate home interiors, movie sets, public displays, or even theatre props.

Medicine :Most of the casts and medical bandages are created with Plaster of Paris. PoP is used with gauze bandages to create a moldable sculpting material called plaster bandages. It is used in a similar fashion to clay, as it can be easily shaped when it is wet and will set into a lightweight and sturdy structure.

This material is used to make orthopedic plaster casts to help set broken and deformed bones. Plaster is widely used as a support for broken bones; a bandage impregnated with plaster is moistened and then wrapped around the damaged limb, setting into a close-fitting yet easily removed tube, known as an orthopedic cast.

Radiotherapy : Plaster of Paris is used in pre-treatment prepping for radiotherapy. It is used for the fabrication of individual immobilization shells for patients.

Plaster bandages are used to construct an impression of a patient’s head and neck, and liquid plaster is used to fill the impression and produce a plaster bust.

The transparent material polymethyl methacrylate (Plexiglas, Perspex) is then vacuum formed over this bust to create a clear face mask which will hold the patient’s head steady while radiation is being delivered.

Decorative Architecture : Stucco Plaster of Plaster is used for creating complex and intricate structures used for decorating room interiors. These designs are usually artistic, geometric, or abstract.

The Plaster is extensively used to simulate the appearance of wood, stone or naturalistic objects in substantial buildings.

Plaster of Paris (PoP) is also used for making False Ceilings. For this, the powder form of Plaster of Paris is taken and converted into a sheet form, and this sheet is then fixed to the base ceiling using multiple fasteners.

These ceilings can be done in a variety of designs, lights and colours. The most common use of Plaster of Paris is seen in the construction and development of houses. After completing the construction, usually, the plaster is applied before painting the walls. Once the plaster sets on the wall, the wall is deemed ready to be painted.

Dentistry : Plaster of Paris is widely used in mounting the models and casts of oral tissues, teeth and gums. These casted models are usually created from dental stone, which is a harder, denser and stronger derivative of PoP. It is created by exposing gypsum to excessive pressure.

Plaster is also used to make and mould wax dentures, where the wax is removed by burning it out, and the dentist replaces it with a more flexible, flowable denture base material. The acrylic denture base is then cured inside a mould of the plaster investment. These investment moulds can withstand a high degree of heat and pressure required for a rigid denture base.

Fire Protection : Plasters of Paris is used in incorporating passive fire protection and as fireproofing products. Plaster of Paris tends to retain water, and the finished plaster releases copious amounts of water vapor when exposed to a fire.

This water acts as a flame-retardant and slows the spread of the flames. It also provides insulation from flame and heat to certain steel structures, which would collapse due to loss in strength from the heat.

Material Storage of Plaster of Paris
