Uses of Plaster
Plaster can is best for a variety of purposes. This substance consists of powders of several distinct stones, such as gypsum. The stone can be ground and mixed with water to make a paste that will solidify if exposed to air.
When it comes to its applications, all of the types of plaster have different use cases in diverse industries such as construction, medical or even art.
1. Construction Industry
One of the most common uses for Plaster in the building is drywall, which is generally a form of gypsum plaster. This Plaster may help in creating an internal wall surface in homes and other structures.
Though it creates a firm surface suitable for interior walls, this sort of plaster is free from damages and does not hold up well when exposed to the elements.
In many parts of the world where drywall is not common, the most common type of plaster is cementitious and sand / Filler based plaster. There is a lot of innovation going on in premix plasters, especially in countries like Pakistan. A good example would be Ressichem and its Ressi PlastoRend 120 dry premix general purpose ready to use plaster.

Decorative trim is another popular application for plaster in construction.

We can carve this plaster into various forms or designs as trim in order to improve a building’s aesthetic qualities.
