What are the different types of rendering

house rendering

Wall rendering is a popular technique used in Australian construction and architecture to enhance the durability, aesthetics, and weather resistance of exterior walls. Rendering involves applying a mixture of various additives onto wall surfaces, creating protective layers that can be further textured or painted. Today, we will explore the various types of wall-rendering techniques commonly employed in the Australian construction industry.

Cement render

Cement render is a widely used and versatile wall rendering technique that provides a strong and durable finish. It involves a mixture of cement, sand, and water, which is applied directly onto the wall surface. Cement render offers excellent protection against moisture and external elements, making it suitable for both interior and exterior applications. It can be applied in various finishes, from smooth and sleek to textured and rustic, depending on the desired aesthetic. Cement render is known for its robustness, longevity, and cost-effectiveness, making it a popular choice in home construction projects worldwide.

Acrylic render

Acrylic render is a modern rendering system that incorporates acrylic polymers into the mixture, offering several advantages over traditional cement renders. The addition of acrylic polymers enhances the flexibility and crack resistance of the render, making it more durable and long-lasting. Acrylic render is known for its great adhesion ability, making it easy to bond effectively with different substrates. This renders it suitable for various applications, from exterior walls to interior surfaces. One of the notable benefits of acrylic render is its extensive range of finishes and colours. It is available in a variety of textures, such as smooth, fine, or coarse, allowing for customization according to design preferences. Acrylic render is also resistant to fading and can withstand exposure to UV rays, ensuring the longevity of its look.

Polymer render

Polymer render is a synthetic rendering that utilizes polymer-based binders instead of traditional cement. This type of render offers several advantages, including enhanced water resistance and flexibility. Polymer render forms a protective barrier on the wall surface, preventing water penetration and protecting against moisture-related issues such as dampness or efflorescence. It is particularly suitable for areas that experience high humidity or frequent temperature fluctuations, as it exhibits excellent resistance to cracking and shrinking. Polymer render is suitable for both new construction and renovation projects, providing a reliable and long-lasting finish. It can also be tinted to achieve different colours and is available in a range of finishes.

Lime render

Lime render is a traditional technique that has been used for centuries and is known for its unique properties. Unlike cement-based renders, lime render is less prone to cracking due to its excellent flexibility. It has the ability to expand and contract with changes in temperature and humidity, accommodating the natural movements of the underlying structure. This flexibility helps to distribute stress evenly, reducing the likelihood of cracks forming on the surface. The breathability of lime render also contributes to its crack resistance, making it a good choice for home renovations. Lime is a porous material that allows the wall to “breathe” by enabling the passage of moisture vapour. This quality prevents the buildup of trapped moisture, which can lead to structural issues and the formation of cracks. The breathability of lime render helps to maintain a healthy and balanced moisture level within the walls.

Monocouche render

Monocouche render, also known as through-colour render, is a pre-mixed rendering system that offers a range of benefits and simplifies the application process. Unlike traditional renders that require a separate layer of paint, monocouche render contains pigments that provide consistent colour throughout the thickness of the render. This eliminates the need for additional painting, saving time and reducing maintenance requirements. It’s a popular option for house rendering in Sydney and NSW in general. Monocouche render is available in a variety of colours and finishes, allowing for diverse design possibilities. The application of monocouche render is relatively straightforward, making it a popular choice for both professional contractors and DIY enthusiasts. It can be applied in a single layer, reducing the overall time and effort involved.

Silicone render

Silicone render is a popular choice for wall rendering in Australia due to its low-maintenance properties. This type of render is formulated with silicone-based additives alongside cement, which allow excellent water repellency. The hydrophobic nature of silicone render prevents water from penetrating the surface, reducing the risk of moisture-related damage and mould growth. One of the key advantages of silicone render is its resistance to dirt and algae buildup. Its smooth and non-porous surface minimizes the adhesion of dirt particles and biological growth, making it easier to keep the rendered surface clean. Unlike other render types that may require regular cleaning or repainting, silicone render requires minimal maintenance.


Wall rendering is a crucial technique used in construction and architecture to enhance the durability, aesthetics, and weather resistance of exterior walls. From the traditional cement render to the modern acrylic and polymer renders, each rendering type offers unique benefits and characteristics. Each rendering type has its own advantages, and the choice depends on factors such as climate conditions, building structure, desired aesthetics, and maintenance requirements. Consultation with professionals is recommended to ensure proper application and achieve the desired results.
