The Factors that Influence Rendering Cost per m2 Explained

Rendering is a popular technique used in construction and architecture to provide a protective and aesthetically pleasing finish to a building’s exterior walls. When considering rendering for your project, one of the key factors that you need to take into account is the cost per square meter (m2). Understanding the factors that influence rendering cost per m2 can help you make informed decisions and ensure that you stay within your budget. In this article, we will explore these factors in detail.

Type of Rendering Material:

One of the primary factors affecting rendering cost per m2 is the type of material used. There are various options available in the market, including cement render, acrylic render, lime render, and polymer render. Each material has its own unique characteristics and price range.

Cement render is one of the most commonly used materials due to its durability and affordability. Acrylic render, on the other hand, offers excellent flexibility and crack resistance but comes at a slightly higher cost. Lime render is known for its breathability and natural appearance but may be more expensive than other options. Polymer render is a relatively new option that offers enhanced waterproofing properties but may also be more costly.

It’s important to consider your project requirements, such as climate conditions, desired finish, and budget when selecting the rendering material as it directly affects the overall cost per m2.

Surface Preparation:

Another crucial factor influencing rendering cost per m2 is surface preparation. Before applying any rendering material, it is essential to ensure that the surface is clean, smooth, and free from any defects or loose particles.

If your existing walls require extensive preparation work such as cleaning, repairing cracks or holes, or applying an undercoat primer for better adhesion, it can significantly impact the overall cost per m2. The condition of your walls will determine how much time and effort are needed for surface preparation before rendering can begin.


Complexity of the Project:

The complexity of the project is another key factor that affects rendering cost per m2. The more intricate and detailed the design, the more time, effort, and expertise it will require from the rendering professionals.

Projects with multiple angles, curves, or decorative elements may require additional skills and techniques to achieve a flawless finish. This increased level of complexity can result in higher labor costs and subsequently impact the overall cost per m2.


Size of the Project:

Last but not least, the size of your project plays a significant role in determining rendering cost per m2. Generally, larger projects tend to have a lower cost per m2 compared to smaller ones.

This is because larger projects benefit from economies of scale. Rendering professionals can efficiently utilize their resources when working on bigger areas, resulting in lower costs per square meter. Conversely, smaller projects may require more precision and attention to detail, which can increase the overall cost per m2.


In conclusion, several factors influence rendering cost per m2. These include the type of rendering material chosen, surface preparation requirements, complexity of the project design, and size of the project itself. By considering these factors carefully and consulting with experienced professionals, you can make informed decisions that balance your budget with achieving an aesthetically pleasing and durable rendered finish for your building’s exterior walls.
