Some of you may think that Gypsum plastering is a new and emerging technology in the construction field, but actually, it is as old as the ancient pyramids, about 3000 years. Gypsum is a soft sulfate material composed of calcium sulfate dihydrate that’s widely used as a fertilizer, in sculptures & as a plaster material. Gypsum is available in a powdered form, appears like a white chalk material, and is extremely light in weight.
In recent years, the development sector has witnessed a variety of latest trends, technology advancements, and innovations across applications. All are aimed toward making construction faster and delivering higher performance. In today’s era, Gypsum has proved to be a miraculous material aiding interior construction because of its properties. Gypsum plaster is preferred mostly due to its superior finish glow, shiny and reflective, and time-saving attributes.
Popular Uses of Gypsum Plaster
- Gypsum is soundproof, fire-resistant, and has a low thermal conductivity which saves electrical costs. Regulates humidity and improves air quality.
- Gypsum is non-combustible and contains a high content of crystal water. In the event of a fire, it acts as a barrier and protects blockwork, concrete, and steel.
- Gypsum can be used for decorative applications. It can be easily applied to decorative materials and can be molded into different shapes. Also used for Ornamental works. Toys, Cosmetics, Blackboard, chalk.

Gypsum Plaster V/S Plaster of Paris (PoP)
Occurrence: Gypsum plaster is a naturally occurring mineral and Plaster of Paris is a man-made material.
Chemical name: The chemical name of gypsum is known as calcium sulfate dihydrate and PoP is known as calcium sulfate hemihydrate.
Forms: The availability of gypsum plaster is easy and ready to install. Whereas Pop comes in powdered form.
Design and aesthetics: Gypsum plaster can only be achieved in square or rectangular shapes or designs, but from PoP, any design or shape can be achieved.
Molding: Gypsum can’t be molded into any different shapes and in the case of PoP, it can be molded into different shapes if mixed with water.
Finishing: The gypsum plasterboards offer a clean and furnished look to the ceilings. Pop doesn’t have the same finesse as that of the Gypsum Boards.
False Ceiling: Gypsum plasterboards are easy to install for false ceilings and also as partition walls in offices. On the other hand, to make a PoP false ceiling, the paste is applied to the chicken mesh to add mechanical strength. The pop ceiling is seamless and moldable.
Strength: Gypsum plaster has more strength as compared to plaster of Paris. PoP is weaker.
Durability: Gypsum has less durability than PoP. Its maximum lifespan is 5 years and PoP has more durability with a lifespan of 10 -15 years.
