Gypsum Plastering vs. Normal Plastering

Attribute	Gypsum Plastering	Normal Plastering
Material Composition	Contains gypsum as the main ingredient	Contains cement, sand, and water
Drying Time	Dries faster due to gypsum content	Requires more time to dry compared to gypsum plastering
Strength	Less strong compared to normal plastering	Provides better strength and durability
Cost	Generally more expensive	Usually more cost-effective
Application	Suitable for interior walls and ceilings	Can be used for both interior and exterior surfaces

Introduction

Plastering is an essential part of construction, providing a smooth and even finish to walls and ceilings. There are different types of plastering materials available, with gypsum plastering and normal plastering being two popular options. Both have their own set of attributes and benefits, making them suitable for different applications.

Composition

Gypsum plastering, as the name suggests, is made from gypsum powder mixed with water to form a paste. This paste is then applied to the surface to be plastered. On the other hand, normal plastering typically consists of a mixture of cement, sand, and water. The composition of these two types of plastering materials plays a significant role in determining their properties and performance.

Setting Time

One of the key differences between gypsum plastering and normal plastering is the setting time. Gypsum plaster sets much faster compared to normal plaster, making it a preferred choice for projects that require quick completion. Gypsum plaster can set in as little as 20-30 minutes, while normal plaster may take several hours to set completely.

Strength

When it comes to strength, normal plastering is generally considered to be stronger than gypsum plastering. The cement content in normal plaster provides better durability and resistance to wear and tear. This makes normal plastering a suitable choice for areas that are prone to high impact or heavy traffic.

Flexibility

Gypsum plastering offers better flexibility compared to normal plastering. This means that gypsum plaster can accommodate slight movements in the structure without cracking. This makes gypsum plastering ideal for buildings that are prone to settling or shifting, as it can help prevent cracks from forming on the surface.

Finish

Both gypsum plastering and normal plastering can provide a smooth and even finish to walls and ceilings. However, gypsum plastering is known for its superior finish quality. Gypsum plaster dries to a harder and smoother surface compared to normal plaster, resulting in a more polished look. This makes gypsum plastering a popular choice for interior walls that require a flawless finish.

Cost

Cost is an important factor to consider when choosing between gypsum plastering and normal plastering. Gypsum plaster is generally more expensive than normal plaster due to the higher cost of gypsum powder. However, the faster setting time of gypsum plaster can help reduce labor costs, making it a cost-effective option for projects with tight deadlines.

Application

Both gypsum plastering and normal plastering can be applied using similar techniques, such as troweling or spraying. However, gypsum plastering is more commonly used for interior walls and ceilings, where a smooth finish is desired. Normal plastering, on the other hand, is often used for exterior walls and surfaces that require greater strength and durability.

Conclusion

In conclusion, both gypsum plastering and normal plastering have their own unique attributes and benefits. Gypsum plastering offers quick setting time, superior finish quality, and flexibility, making it ideal for interior applications. On the other hand, normal plastering provides greater strength and durability, making it suitable for exterior surfaces. Ultimately, the choice between gypsum plastering and normal plastering will depend on the specific requirements of the project and the desired outcome.
