Difference Between Mortar and Gypsum Plaster in Construction

When it comes to construction, achieving durable and aesthetically pleasing walls and ceilings is crucial. Two commonly used materials in this regard are mortar and gypsum plaster. Both materials serve distinct purposes, and understanding their differences can help professionals and homeowners make informed decisions for their construction projects. In this blog, we will delve into the key distinctions between mortar and gypsum plaster, their advantages, disadvantages, and applications, along with why gypsum plaster is gaining popularity in modern construction.

What Is Mortar?

Mortar is a traditional building material made by mixing cement, sand, and water. It is primarily used as a binding agent for laying bricks, blocks, and stones. Mortar is also applied as a plaster to smoothen walls and ceilings, providing a base for painting or decorating.

Types of Mortar

1. Cement Mortar
   Made from cement and sand, cement mortar is durable and commonly used in structural applications.

2. Lime Mortar
   A mix of lime and sand, lime mortar is more flexible and environmentally friendly compared to cement mortar.

3. Gypsum Mortar
   Contains gypsum instead of cement as a binding material and is used for specific interior applications.

What Is Gypsum Plaster?

Gypsum plaster is a modern alternative to traditional plastering materials. It is made from gypsum, a naturally occurring mineral composed of calcium sulfate dihydrate. Gypsum plaster is applied as a thin layer over walls and ceilings to create a smooth, durable surface.
