Cement rendering has been a popular method of enhancing the exterior of houses for many years. It not only serves as a protective coating for walls but also adds an attractive finish, improving the overall aesthetic of a home. Whether you’re renovating or building a new property, cement rendering can be a great way to transform the appearance of your house. This article will explore various tips for achieving the best cement rendering results, ensuring that your home looks stunning while enjoying long-lasting durability.
1. Choose the Right Render for Your Home
Before you begin rendering, choosing the right type of render is important. There are several options available, each suited for different surfaces and climates. The most common types of cement renders include:
- Traditional Cement Render: This is the most widely used form of rendering. It is made from a mixture of sand, cement, and lime. It offers a strong finish and can be applied to various surfaces, including brick and concrete.
- Acrylic Render: This is a modern, more flexible version of cement render. It is mixed with acrylic resins, which help create a more durable and water-resistant finish. Acrylic render is ideal for areas with extreme weather conditions, as it is more cracking-resistant.
- Polymer Render: Similar to acrylic render, polymer-based render is mixed with additional materials to increase its strength and elasticity. It’s known for its smooth, clean finish and can be a great choice for contemporary homes.
Choosing the right render depends on factors such as your home’s location, the type of walls, and the finish you desire. Consult a professional renderer or contractor to help you make the right choice for your property.
2. Prepare Your Walls Properly
The preparation of the surface is a crucial part of the rendering process. The better the surface preparation, the better the final result will be. Clean the walls thoroughly to remove any dirt, dust, or debris. If your walls are already painted, you’ll need to scrape off the old paint to expose the bare surface for better adhesion. If the wall has cracks or holes, patch them up using a suitable filler to ensure a smooth surface.
For better bonding, dampening the wall slightly before applying the render is also advisable. This prevents the dry wall from absorbing too much moisture from the render mix, possibly leading to cracking.
3. Mix the Render Correctly
Achieving the right consistency when mixing the render is key to a professional finish. Cement render should be mixed with the right proportion of sand, cement, and water. For traditional renders, a typical mix is 4 parts sand to 1 part cement. However, be sure to check the manufacturer’s instructions for pre-mixed renders or any additional additives you might need.
The render should have a thick, workable consistency—not runny or dry. Mixing the ingredients thoroughly is important to avoid lumps or uneven distribution of materials.
4. Apply the Render Evenly
When applying the render, ensuring the coat is even and smooth is essential. Use a stainless steel trowel to spread the render across the wall in small, manageable sections. Start at the bottom of the wall and work your way up, ensuring you apply an even coat of render to each section.
To achieve a smooth finish, use a float to smooth out the surface once the render has been applied. A sponge float is ideal for creating a more polished look, while a wooden float can give a more textured finish, depending on your desired look.
5. Consider Textured Finishes
One of the great benefits of cement rendering is the variety of finishes it can achieve. Whether you want a smooth, sleek look or a textured finish, the cement render can be tailored to suit your taste. Some of the most common textured finishes include:
- Sand Finish: This is a simple, classic finish that gives the wet render a rough texture by applying sand.
- Brush Finish: This finish involves brushing the wet render with a stiff brush to create a soft texture.
- Pebble Dash: A more dramatic, rustic finish, pebble dash involves throwing small pebbles onto the wet render, creating a bumpy texture.
- Polished Finish: For a sleek, modern look, you can use a polished finish, where the render is smoothed and then polished for a glossy, contemporary appearance.
You can choose the texture based on your home’s style. A polished finish may suit modern homes, while a pebbled dash finish may be better for traditional or rustic homes.

7. Allow Sufficient Curing Time
Once the render has been applied, it’s important to allow sufficient time for curing. Curing helps to ensure that the cement hardens properly, ensuring a strong and durable finish. You should leave the render to cure for at least 7 days. During this time, it is important to keep the render moist, especially in hot weather, to prevent it from drying too quickly and cracking.
8. Maintain the Rendered Surface
After the render has cured and dried, regular maintenance is important to keep it looking fresh. Clean the rendered surface regularly to remove dirt and grime, which can dull the appearance. If you notice any cracks or chips, it’s important to repair them quickly to prevent moisture from seeping in and causing further damage.
Applying a coat of exterior paint after the render has fully cured can also help protect the surface from the elements and enhance the visual appeal of your home.
