Difference Between Plastering and Pointing

What is Plastering?

Before you understand how to plaster a wall, it's important to understand what it is. Plastering is the process of applying a smooth, even layer of a mixture called plaster to the surface of walls, ceilings, or partitions. This mixture typically consists of cement, sand, and water, although additional ingredients such as lime or gypsum may be added to improve workability and performance. The primary purpose of plastering is to provide a protective coating, enhancing the durability and appearance of the structure. Plastering also helps in creating a smooth, level surface that is ideal for painting or other decorative finishes.

What is Pointing?

Pointing, on the other hand, is the process of finishing the exposed joints between bricks or stones in masonry construction. This technique involves filling the joints with a mortar mix, which is often made of cement, sand, and water, similar to plaster. The primary purpose of pointing in construction is to prevent water penetration and enhance the structural integrity of the building. It also contributes to the overall appearance, highlighting the individual units and giving a neat and finished look to the walls.

Difference between Plastering and Pointing

While understanding the difference between plastering and pointing, we need to understand a few key differences:

1) Application

Plastering is applied to entire surfaces, covering walls and ceilings, providing a smooth and consistent finish. Pointing, on the other hand, is specifically applied to the joints between individual units, such as bricks or stones.

2) Function

Plastering primarily focuses on enhancing the appearance of a surface and providing protection against external elements. It creates a decorative and functional coating. In contrast, pointing serves as a structural reinforcement, preventing water ingress and maintaining the stability of masonry structures.

3) Materials

Plastering typically uses a mixture of cement, sand, and water, while pointing predominantly employs mortar. The choice of materials may vary depending on the specific requirements of the project.

4) Tools and Techniques

Plastering involves the use of trowels, floats, and other tools to spread the plaster evenly and achieve the desired texture. Pointing requires specialised pointing tools, such as pointing trowels and jointers, to fill the gaps between the units accurately.

5) Scope of Work

Plastering involves covering large areas, such as entire walls or ceilings, requiring a broader application and a more extensive surface preparation. Pointing, on the other hand, is typically performed on smaller sections, focusing specifically on the joints between individual units.

6) Time and Cost

Plastering usually requires more time and effort due to the larger surface area involved. It may also involve additional steps such as plasterboard installation and basecoat application. Pointing, being a localised process, is generally quicker and more cost-effective.

7) Visual Impact

Plastering contributes significantly to the overall aesthetics of a building, providing a smooth and finished appearance. It allows for various decorative finishes, such as textured or polished surfaces. Pointing, while less visually prominent, enhances the character and charm of masonry structures by highlighting the individual units and creating clean, neat joints.

8) Maintenance

Plastering may require periodic maintenance, such as repainting or patching, to keep the surface in good condition. Pointing, once done correctly, generally requires minimal maintenance, as its primary function is to protect the joints and maintain the structural integrity of the masonry.
