Advantages of Gypsum Plaster

Gypsum is a soft sulfate mineral consisting of calcium sulfate dihydrate (CaSO4:2H20). It is widely used as a fertilization, mold, sculpture and plaster material.

Gypsum is a chalk-like material that is very light in weight. It exists in nature in crystalline form.

In recent years, the construction industry has witnessed many new trends, technological advances and application innovations, all aimed at speeding up construction and providing higher performance.

Although a material older than cement and mortar, gypsum has rarely been widely used in the construction industry. Now, thanks to its properties, gypsum has proven to be a fantastic material that helps in interior construction.

What is Plaster of Paris?

Cooked gypsum is obtained by crushing gypsum (calcium sulfate hemihydrate CaSO 4 0.5H 2 O) heated to 150 degrees Celsius.


After the addition of water, the cooked gypsum (POP) becomes again normal gypsum (dihydrate), resulting in a hardening of the resulting material. This hardened material can be used to make molds for casting and construction.


What is gypsum powder?

When dry POP powder is mixed with water, it hardens. This material, which can be applied to brick, block or concrete surfaces to create a smooth surface, is called gypsum plaster.


Earlier, a 6 mm thick layer of gypsum plaster (called POP punning) was usually applied on top of the cement plaster to smooth it out before painting. This is a two-stage process involving various elements that must be mixed on site, such as sand, cement and water. This process is slowly being replaced by the direct application of a layer of gypsum plaster. In gypsum plaster, a ready-made POP powder is mixed with water and applied directly to the wall.

Gypsum plaster can be applied directly to any brick, solid or hollow block, AAC block and gypsum board. Gypsum plaster has good insulating properties, is fire resistant and impact resistant. In addition, gypsum saves a lot of time during construction and has an excellent finish. These properties clearly caught the attention of real estate builders and contractors, who chose gypsum plaster over traditional cement plaster.


Advantages of gypsum plaster

Contractors and builders began to prefer gypsum plaster over its excellent finish and time-saving properties. Some of the advantages of gypsum plaster are


Ease of application (workability): Plaster can be applied directly to brick/block work without separate finishing. It is also easy to apply and level gypsum plaster.


No shrinkage cracks: The reaction of gypsum generates less heat than the reaction of cement with water. Therefore, gypsum plaster has less shrinkage cracks than traditional cement plaster


Fast setting time: gypsum sets quickly (i.e. within 25-30 minutes). Therefore, painting can be started 72 hours after the application of gypsum plaster. The plaster must be dry before painting.

No maintenance time: unlike traditional cement plasters, gypsum plasters do not require any maintenance during the application process, saving water and time


High productivity: greatly reduced time compared to traditional cement plaster


High performance: excellent high strength after drying, durable and light weight (reduces static loads on the structure).
