Concrete Render VS Cement Render

Renders are vital to a building’s aesthetic, both inside and out. They prepare the wall substrate, ensuring a smooth surface that can then be painted, textured, or clad. Selecting the right render is essential to achieving the best results for your project. In this article, we’ll explore the differences between concrete render and cement render, helping you make an informed decision.

What is Concrete Rendering?

External walls, concrete, and bricks are commonly finished using a type of process called concrete rendering. Cement, sand, and concrete are combined to form a sturdy and long-lasting base coat. This render is often applied in deeper layers for added strength because it is both aesthetically pleasing and long-lasting. It can also be completed in a larger spectrum of colours.

This type of rendering is popular because it resists weathering and cracking, making it ideal for outdoor applications. Since concrete rendering is cost-effective and long-lasting, it’s a good choice for areas exposed to the elements. However, it does take longer to cure—up to 28 days—compared to other options.

What is Cement Render?

Cement render is one of the most commonly applied to bricks and other surfaces in Australia. Made from a mix of sand and cement, often with lime added for a smoother finish, it is widely used on both interior and exterior walls. Cement rendering can be applied to a variety of surfaces, including stone and concrete blocks.

While cement rendering offers a classic, timeless look, it is more prone to cracking, so it may require regular upkeep. Compared to concrete rendering, cement rendering has its pros and cons: it’s affordable and simple to apply, but lacks the flexibility and crack resistance that concrete rendering experts recommend.

Differences Between Concrete Render and Cement Render

Composition

The primary difference between concrete render and cement render lies in their composition. Concrete render includes concrete, sand, and cement, giving it added strength. In contrast, cement render consists of sand and cement, with lime sometimes added to improve workability and texture.

Application

Concrete render is typically applied in thicker layers than cement render. This provides extra durability, though it takes longer to dry. Cement render is easier to apply, particularly on exterior walls and bricks, but doesn’t offer as much structural support as concrete-based rendering.

Durability

Concrete render is the more durable option, especially for exterior walls. Its ability to withstand harsh weather conditions and resist cracking makes it a popular choice for outdoor projects. Cement render, while sturdy, is more prone to cracking over time and may require repairs.

Flexibility

Compared to acrylic rendering, both concrete and cement rendering lack flexibility. However, applying cement render with acrylic can enhance its flexibility, reducing the risk of cracking on exterior surfaces that expand and contract with temperature changes.

Aesthetic Choices

Both types of rendering can be customised with a range of colours. Concrete render offers a more industrial and modern look, while cement render is often used in traditional designs. The choice between the two depends on the aesthetic you’re aiming for.

Drying Time

Because of its density, concrete render takes up to 28 days to dry, but cement render dries faster but can require more top coats to get the right gloss.

Ready To Choose?

It’s crucial to consider the benefits and drawbacks before choosing between concrete render and cement render. While cement render is easier to apply and less expensive, concrete render is more resilient. Using cement render with acrylic can be the ideal choice if flexibility is an issue because it helps keep various surfaces from breaking.
