- Mortar is a mixture of cement or lime, sand, and water used for bonding units in masonry.
- Plaster is applied as a coating for a smooth surface finish and protection against weathering[^1^][^2^][^3^].
The Purpose Of Mortar In Masonry
Mortar is crucial in masonry construction, as it provides a strong bond between stones, bricks, or blocks, ensuring structural integrity. It fills gaps between units, preventing the entry of water, air, and other compromising elements.
In addition to bonding, mortar enhances the load-bearing capacity of the masonry structure. It evenly distributes weight across units, increasing resistance to forces like wind, earthquakes, and settling.
Different materials can be used to make mortar. These include lime mortar, cement mortar, or a mixture of lime and cement mortar. The specific material used depends on project requirements, with each type offering unique advantages like breathability, flexibility, or increased strength.
Benefits of mortar in masonry construction:
- Strong bond
- Structural integrity
- Gap filling
- Protection against water and air infiltration
- Enhanced load-bearing capacity
- Resistance to wind, earthquakes, and settling
The Purpose Of Plaster In Masonry
Plaster is an essential component in masonry, serving various purposes. It is applied as a coating on both the exterior and interior walls to achieve a smooth and visually appealing finish.
Apart from enhancing the aesthetics, plastering also provides protection to the walls. It acts as a barrier against moisture, preventing water penetration and reducing the risk of dampness or water damage. Additionally, plaster helps to conceal any imperfections or irregularities in the underlying masonry work, resulting in a flawless surface.
There are different materials that can be used for plastering, such as lime, cement, or a combination of both. The choice of plastering material depends on factors like the desired finish, the location of the building, and the environmental conditions it will face.
The Process Of Plastering In Masonry
Plastering is a skilled process that involves applying mortar coats to achieve a smooth surface finish. The process begins with the preparation of the surface by cleaning it and ensuring it is free from any loose particles or debris.
Once the surface is prepared, the plaster is mixed using the appropriate ratio of materials, such as lime, cement, sand, and water. The plaster is then applied in multiple coats, starting with a scratch coat, followed by a floating coat, and finally a finishing coat. Each layer is allowed to dry before the next one is applied, ensuring a strong bond and a smooth finish.
Plastering requires expertise and precision to achieve the desired results. A skilled plasterer will ensure that each coat is applied evenly and smoothly, eliminating any imperfections or irregularities on the surface. The final result is a visually appealing and durable finish that enhances the overall aesthetics of the masonry work.

The Importance Of Pointing In Masonry
Pointing is a specialized mortar finishing technique used in masonry construction. It involves raking and filling the exposed joints or surfaces to provide a stronger bond and enhance the visual appearance of the masonry work.
Pointing serves both functional and aesthetic purposes. It strengthens the masonry structure by filling the gaps between individual units, preventing the entry of water, air, and other elements. This helps to maintain the structural integrity of the building and increases its durability.
In addition to its functional benefits, pointing also adds to the aesthetic value of stone masonry. It can be done using different mortar mix proportions, depending on the desired effect. Lime mortar is commonly used in a 1:2 mix proportion for pointing, while cement mortar is used in a 1:3 mix proportion. The choice of mortar mix affects the color, texture, and overall appearance of the joints, adding perfection and aesthetic value to the masonry work.
In summary, mortar and plaster are essential components of masonry construction. While mortar is used for joining stones, bricks, and blocks, plaster is used for rendering on the outside and inside of walls. Plastering provides a smooth surface finish, conceals imperfect workmanship, and protects walls from weathering. Pointing, on the other hand, reinforces the masonry structure and enhances its visual appeal. Understanding the differences between these techniques is crucial for achieving both structural stability and aesthetic beauty in masonry.
