Rendering and Plastering: Addressing the Confusion

Rendering and plastering are terms that have become interchangeable when constructing walls. However, is there really a distinct difference between the two? Rendering is defined as the application of premixed mortar over a wall. This becomes the foundation for further finishing work such as paint. On the other hand, plastering is derived from the root word plaster. Plaster refers to the material used for the decorative or protective layer on walls and mouldings.


What is wall rendering?

Wall rendering is commonly used for exterior walls. This is done to add a protective layer against wear and tear. Since exterior walls should be more durable, wall rendering is very important. The combination of materials used for wall rendering may vary. The vital aspect of the process is the resulting wall should be strong. These days, some contractors opt for a coarser combination of sand and cement to render exterior walls. Other decorative options are available to the owner. Paint, decorative bricks, and other materials can be placed on top as a final finishing touch.

A rendered wall should be resistant to wind, water, and even fire. There are materials used for wall rendering that can make it fireproof. Fireproofing has also become increasingly popular especially with interior and exterior walls. Like most constructions these days, a rendering machine is also used for increased efficiency and better quality of work. Contractors rely on the use of these machines for consistent results.

What is the purpose of plastering?

Plastering is primarily used on interior walls. In contrast with wall rendering, plastering is done to result in a more decorative finish. Plastering ensures a smooth and clean finish to the wall. This will also allow the homeowner to customise the wall with paint, wallpaper, and other decorative materials. Similar to wall rendering, there are different types of plaster material used in construction. Contractors can either use clay plaster, cement plaster, lime plaster, or gypsum plaster. Each material has a specific purpose and should be chosen according to the material to which it will be applied. Of these plaster material options, the most commonly used is cement plaster due to its strength and durability. Cement plaster can also be used in fireproofing.

In any case, plastering and wall rendering can be interchanged. Rendering machines can be used for both. A machine can be instrumental in making sure that each of these jobs is done right. Investing in the right equipment used in rendering and plastering has many advantages. While contractors may use different materials depending on the need and requirement of the client, needless to say, plastering and wall rendering are two of the most important foundations in the construction of a building.
