How to Cement Render a Wall




Cement rendering is a popular method used to improve the appearance and durability of exterior walls. It involves applying a mixture of sand, cement, and sometimes lime to the surface of a wall to create a smooth or textured finish. While it is possible to attempt cement rendering as a DIY project, it is often best left to professionals who have the expertise and equipment to ensure a high-quality finish. Here is a comprehensive guide on how professionals typically carry out cement rendering:

 

Preparation of the Wall

Before applying the render, the wall needs to be prepared properly. This involves cleaning the surface to remove any dirt, debris, or loose material. Any cracks or holes should be patched up and allowed to dry completely.

 

Applying a Bonding Agent

A bonding agent or primer is often applied to the surface of the wall to help the render adhere better. This step is essential for ensuring a strong bond between the render and the wall surface.

 

Mixing the Render

The render mixture typically consists of cement, sand, and sometimes lime. Professionals carefully mix these ingredients in the correct proportions to achieve the desired consistency. The mixture should be smooth and free of lumps to ensure a uniform finish.

 

Applying the Render

Once the render is mixed, it is applied to the wall using a trowel or rendering machine. Professionals have the skills and experience to apply the render evenly and smoothly, ensuring a professional-looking finish. They may apply multiple coats, depending on the desired thickness and texture.

 

Smoothing and Leveling

After applying each coat of render, professionals use a straight edge or float to smooth and level the surface. This helps to remove any excess material and create a flat, even finish. They pay close attention to detail to ensure a high-quality result.

 

Texturing (if desired)

Depending on the desired finish, professionals may add texture to the surface of the render. This can be achieved using various tools and techniques, such as sponges, brushes, or speciality trowels. Texturing adds visual interest and can help to disguise imperfections in the wall surface.

 

Curing and Drying

Once the rendering is complete, it needs time to cure and dry properly. This process can take several days, during which time the wall should be protected from rain, direct sunlight, and extreme temperatures. Professionals take care to ensure that the render cures evenly and thoroughly for maximum durability.

 

Finishing Touches

After the render has dried completely, professionals may apply a final coat of sealant or paint to protect the surface and enhance its appearance. This helps to seal the render and prevent moisture penetration, prolonging its lifespan.

 

Cleanup

Once the job is complete, professionals clean up any leftover materials and debris, leaving the area neat and tidy. They may also dispose of any waste responsibly, following local regulations and guidelines.
