Difference Between Plastering and Pointing in Construction | Uses, Benefits & Cost Guide

In construction, surface finishing is just as important as structural strength. Plastering and pointing are two commonly confused surface finishing techniques. They serve different purposes but are often used in conjunction with each other.

Understanding the difference between plastering and pointing in construction can help you make well-informed choices, whether you’re building from scratch or renovating.

That’s exactly what we’ll explore in this blog.

Plastering involves applying a smooth and even layer of mortar to interior or exterior walls and ceilings. This process serves both aesthetic and functional purposes, enhancing the appearance of surfaces while also providing protection against moisture and weather elements.

Pointing is a process adopted to protect the joints in the masonry from atmospheric conditions. It also improves the asthetic view of the masonry walls.

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

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.

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.

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.

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.

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.

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.

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.

 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.

In summary, plastering and pointing are two distinct techniques used in building construction and renovation. While plastering involves covering entire surfaces with a smooth layer of plaster inside, pointing is used to strengthen and protect brickwork- which is predominantly done on the exterior of structures. Plastering is used to create a smooth and even surface on walls and ceilings, while pointing is used to fill gaps between bricks and protect the structure from water damage.
