The construction industry has evolved a lot, and there are certain aspects of it that must be done with precision so that you can give the building the desired look and finish. Plastering is one such thing. It forms an integral part of both the interiors and exterior of the building. In this blog, we will be unfolding certain details about plastering.

What is Plastering?

Basically, it’s the process of application of cement mortar on the surface of the building. Applying plaster makes the surface smooth and seamless and also acts as a protectant layer. It prevents the surface from atmospheric elements like heat, rain, hail, snow, etc.

There are two objectives for applying Plaster:

1. Adding a protective layer

2. Giving it a decorative appeal

What are the different types of Plaster?

There two types of plasters:

1. Cement plaster- This is the uniform mixture of cement, sand, and water. These are the best for all kinds of plastering works. The commonly used proportion is 1:3, and if you are going for plastering of the interiors, then 1:4 is the right proportion.

2. Gypsum plaster– In this kind of plaster, gypsum is used in the place of cement. Gypsum is a perfect choice for decorative and architectural design. They are resistant to fire and provide better installation. Moreover, gypsum plaster dries up easily and undergoes very little expansion and contraction.

What is the right proportion mix of Plaster?

The right proportion of plastering for the internal wall is 1: 3 and the thickness goes up to 15 mm.

If you are choosing the option of plastering for the ceiling, then the thickness varies between 8mm to 12 mm, and the proportion is 1: 4 (cement: sand)

For external walls, the thickness of the plaster should be 20 mm, and the proportion is 1:6, this is the first coat, then you should go for a second coat or final coat which should be 1:4 and 8 mm thickness plus waterproofing mixtures. This acts as a protectant of the external wall.
