Cement vs. Concrete Render: What’s the Difference and Which One Is Best?

Rendering is a perfect way to improve the look and longevity of your property. Whether you pick cement render or concrete render, both choices give a smooth, modern day finish for exterior and interior walls. 

House rendering not only enhances curb appearance but also provides an additional layer of protection against adverse weather conditions. Rendered walls resist fractures and water damage, making them a long-lasting option for Australian houses.

With a variety of render finishes available, including colored rendered houses and textured surfaces, homeowners may personalize their rendered homes to meet their preferences. Brick rendering and brick render are popular options for changing outdated bricks into clean, modern surfaces. 

Additionally, render and cladding improve insulation, increasing energy efficiency. If you are working on a rendered house renovation or a new build, choosing the right cement render finishes or concrete render mix can make a big difference in both appearance and longevity.

What Is Cement Render?

Cement render is a mixture of cement, sand, lime, and water applied to walls to create a smooth or textured finish. 

It is commonly used on brick render, concrete, and other masonry surfaces to improve appearance and durability. Cement rendering is widely preferred in Australia due to its affordability, strength, and ability to withstand different weather conditions.

Definition and Composition

A cement render mix consists of cement, fine sand, lime (for flexibility), and water. Some mixtures also include additives to improve adhesion and prevent cracking. The consistency and thickness of the render depend on the application and desired render finishes.

Common Uses of Cement Rendering

• Enhancing the exterior of rendered homes and buildings

• Protecting walls from moisture and weather damage

• Transforming old brick walls with brick rendering

• Improving insulation and energy efficiency in rendered houses

• Preparing surfaces for render and cladding
  
  

Popular Cement Render Finishes

• Smooth finish – Ideal for modern rendered walls

• Textured finish – Adds depth and character to rendered homes

• Coloured rendered houses – Achieved by mixing pigments into the cement render finishes

• Trowel or sponge finish – A stylish touch for both indoor and outdoor walls
  
  

Cement rendering is a cost-effective way to upgrade your home’s exterior while ensuring long-lasting protection.

Cement vs. Concrete Render: Key Differences

When choosing the right rendering material for your home, understanding the differences between cement render and concrete render is essential. 

Both materials are popular for house rendering, but they have distinct characteristics in terms of strength, application, aesthetics, cost, and maintenance. 

Let’s explore these key differences in detail.

1. Strength and Durability

Cement render is made from a mix of cement, sand, and lime. It is a strong and flexible option that adheres well to masonry surfaces like bricks and concrete. 

However, cement rendering can develop small cracks over time due to weather exposure and foundation shifts. To reduce cracking, a polymer or acrylic additive can be added to the mix.

On the other hand, concrete render contains a blend of cement, sand, aggregate, and water, making it denser and more durable than cement render. 

Its high cement and aggregate content makes it less prone to cracking and more resistant to external factors like moisture and impact damage. Rendered walls using concrete render are particularly suitable for areas exposed to harsh weather conditions.

If you’re looking for a long-lasting solution, concrete render mix offers better durability, while cement rendering is a flexible and cost-effective option.

2. Application Process and Drying Time

Both cement render and concrete render are applied in layers to achieve the desired thickness and finish, but their application process differs.

Cement Rendering Process:

• A cement render mix is prepared by blending cement, sand, lime, and water.

• The surface is cleaned and primed to ensure strong adhesion.

• The first coat is applied and left to dry before additional layers are added.

• The final render finishes are achieved using a trowel, sponge, or brush.

• Drying time varies but typically takes 24–48 hours for each layer.

Concrete Rendering Process:

• Concrete render mix includes cement, sand, and small aggregates, making it thicker than cement render.

• The application process is similar, but the thicker consistency requires extra care for even spreading.

• Because of its density, concrete render takes longer to dry, sometimes up to 72 hours per layer.

• It is often sealed with a waterproof coating to improve longevity.

For quick application and drying, cement render is preferable, while concrete render is better suited for high-strength requirements.

3. Render Finishes and Aesthetic Appeal

The final appearance of rendered walls significantly depends on the rendering material and finish applied.

Cement Render Finishes:

• Smooth finish: Achieved by troweling the surface for a polished look, commonly used on rendered homes.

• Textured finish: Created using sponges, brushes, or special tools, adding depth to rendered houses.

• Coloured rendered houses: Pigments can be added to the cement render finishes to achieve custom shades.

• Brick rendering: Covers old or unattractive brick surfaces, providing a modern aesthetic.

Concrete Render Finishes:

• Raw concrete look: Maintains a modern, industrial appeal, perfect for contemporary designs.

• Stone effect: Mimics natural stone textures for a rustic or high-end appearance.

• Textured concrete: Ideal for commercial buildings where a robust look is desired.

If aesthetics are a top priority, cement render offers more decorative options. However, concrete render is better suited for a minimalist or industrial look with long-lasting appeal.

Cost Comparison

When choosing between cement render and concrete render, cost plays a crucial role. The price can vary depending on factors like materials, labor, and the size of the project. 

Let’s compare their costs based on different aspects:

1. Material Costs

• Cement Render: Generally more affordable, as it mainly consists of cement, sand, and lime. A standard cement render mix is budget-friendly, making it a cost-effective choice for brick rendering and rendered walls.

• Concrete Render: More expensive due to the addition of aggregates like gravel and specialized binders. Since concrete render mix is denser and more durable, it often costs more per square meter than cement rendering.
  
  

2. Labor Costs

• Cement Rendering: Easier to mix and apply, reducing labor costs. It also dries faster, meaning less time is required for workers to complete a rendered house or rendered wall.

• Concrete Rendering: Requires more expertise and takes longer to apply, increasing labor expenses. Since the process involves thicker application and longer drying times, the overall labor cost can be higher than brick render or cement render finishes.
  
  

3. Maintenance Costs

• Cement Render: Over time, cement render finishes may develop cracks, requiring regular maintenance and potential repairs. This adds to the long-term cost, especially for coloured rendered houses and rendered homes that need repainting.

• Concrete Render: More durable and less prone to cracking, reducing maintenance expenses. Although the initial investment is higher, render and cladding with concrete render can save costs in the long run due to fewer repairs.
  
  

4. Overall Cost Estimation

• Cement Render: Generally costs around $30–$60 per square meter, depending on location and quality.

• Concrete Render: Typically ranges from $50–$100 per square meter, as it requires more material and labor.
  
  

Which One Is More Cost-Effective?

• If you have a tight budget and need a simple yet attractive finish, cement render is a good choice.

• If you’re looking for a long-lasting, durable solution with minimal maintenance, concrete render is worth the higher upfront cost.

Best Rendering Options for Different Surfaces

Choosing the right rendering option depends on the surface you’re working with. Some surfaces require a stronger bond, while others need a flexible finish to prevent cracking. 

Below, we compare brick render, concrete render mix, house rendering, and other options to help you decide the best choice for your project.
