Choosing the right type of render for your home can significantly impact its appearance, durability, and long-term maintenance. Among the most popular finishes used in house rendering today are acrylic rendering and cement rendering. While both serve the primary purpose of protecting and enhancing a property’s exterior, they differ in terms of composition, performance, and suitability for different conditions. Understanding the strengths and limitations of each can help you make the right choice for your home.
Understanding Cement Rendering
Cement rendering is a traditional method that involves applying a mixture of sand, cement, and sometimes lime to the exterior walls of a building. This mixture is usually applied in multiple coats and then painted to achieve the desired look. Cement rendering has been used for decades and remains a reliable option for many homeowners.
One of the main advantages of cement rendering is its affordability. It is often less expensive than modern alternatives and offers a solid, durable surface that can resist wear and tear. It is particularly effective on brick or concrete block structures and gives a classic, textured appearance when applied correctly.
However, cement rendering does have some limitations. It is less flexible than modern rendering materials, meaning it can crack over time, especially if the building experiences movement or is located in an area with extreme temperature changes. It also takes longer to apply and dry, which can extend the overall duration of a house rendering project.
Benefits of Acrylic Rendering
Acrylic rendering is a more recent innovation in the rendering industry. It uses a mixture that includes acrylic resins, giving it superior flexibility and adhesion compared to cement-based renders. This flexibility allows it to cope better with structural movement and reduces the likelihood of cracking.
One of the standout features of acrylic rendering is its ability to be applied to a wide variety of surfaces, including concrete, brick, fibre cement sheeting, and even painted walls. It also dries faster than cement rendering, which can speed up the completion of a project. Additionally, acrylic renders are highly resistant to water, UV rays, and fungal growth, making them a low-maintenance option ideal for harsh or variable climates.
In terms of aesthetics, acrylic rendering offers a smooth, modern finish and comes in a variety of textures and colours. Some acrylic renders are even pre-coloured, eliminating the need for painting and further reducing maintenance costs over time.
Which One Is Right for You?
The choice between acrylic rendering and cement rendering ultimately depends on your budget, the condition of your home, and the finish you desire. Cement rendering may be suitable for homeowners seeking a cost-effective, traditional solution. Acrylic rendering, on the other hand, is ideal for those prioritising flexibility, faster application, and long-term durability. For modern house rendering projects or properties exposed to extreme weather, acrylic rendering often provides the best performance and value.
