Plastering is an important part of any construction and it is the part of the one that gives the building the look and safeguards it from the natural elements.
The cement that is used in plastering must be able to give the wall the look it deserves and must add strength to the outer covering of the building.
Therefore, in this article, we are going to talk about different types of cement that can be used for plastering & which is the best cement for plastering and why?
Best Cement for Plastering
There are various types of cement available in the market for construction purposes, and among them the most common ones are:
OPC or Ordinary Portland Cement made of 95% Cement clinkers mixed with 5% gypsum
PPC or Pozzolana Portland Cement made of 75 to 77% Cement Clinkers with 20% fly Ash added with 3 to 5% of Gypsum
PSC or Portland Slag Cement is made by adding 5 to 6 % of blast furnace slag to the cement clinkers.
Out of these, the OPC is the best cement for plastering work and it is mostly preferred as a plastering cement due to its ability to give immediate strength to the plastering mix and the way it can retain its shape and strength for years to come.
Ordinary Portland Cement is available in three grades of 33, 43, and 53, which are the numbers that indicate the compressive strength of the cement.
While doing the plastering for the buildings the cement used must have high compressive strength and for this, hence grades 43 and 53 of the OPC are the most suitable ones.
The OPC 43 grade is the best choice for plastering work in the low-rise residential and commercial buildings while it is the 53 grade that is chosen for plastering in the high rise and critical projects like Dams, underwater structures, etc.
Why Choose OPC or Ordinary Portland Cement for Plastering?
The OPC 43 and 53 are selected for plastering works due to the following reasons:
High compressive strength that gives the plastering mixture the strength to stick on to the wall surface and remain there as soon as the plastering is applied to the wall
Ability to create a crack-free surface as this cement can form a uniform, smooth, and even surface for covering the masonry work
Ability to be used easily on the walls as it can exhibit a high initial strength to the plastering mixture as soon as it is mixed with water
The smaller and fine granular size that can mix with sand making the plastering mix smooth and even for easy and effective application on the surface to be plastered
High resistance to chemical exposure and the anti-corrosive behavior that makes the OPC the best choice for plastering dams, canals, and other underwater structures so that they can withstand longer against the reaction with the chemicals, salt, and other soluble materials found in water
Thus, the Ordinary Portland Cement grades 43 and 53 are the best cement for plastering in India. Though other cement can be used for plastering, we recommend using OPC Cement with a suitable grade to give the best possible look and protection to your construction.
Other than the type of cement to be used for concrete slab construction, one should always go for the Best Cement Companies in India. The right type of cement, correct grade, and best cement company are all you need to make the best decision.
