How To Cement Render An Internal Brick Wall

Cement rendering is a versatile and durable material that can transform an ordinary brick wall into a smooth and decorative surface. It is a cost-effective way to improve the aesthetics of your home, protect the wall from moisture damage, and increase its insulation value. To ensure a successful cement rendering application, it is crucial to understand the essential aspects of the process. ### Preparing the Wall

Sanding and Cleaning:

> The first step is to prepare the brick wall by sanding down any uneven surfaces and cleaning it thoroughly. Remove any dirt, dust, or loose material to provide a secure bonding surface for the render. ### Applying the Cement Render

Mixing the Render:

> Use a high-quality cement render mix that is specifically designed for internal brick walls. Follow the manufacturer's instructions to mix the render to the correct consistency, ensuring a smooth and workable paste.

Applying the First Coat:

> Use a plastering trowel to apply a thin first coat of render to the prepared wall. Spread the render evenly, pushing it into the gaps and ensuring a smooth surface. Scratch the render with a trowel to create a rough texture for the second coat to adhere to. ### Applying the Second Coat

Waiting Time:

> Allow the first coat to dry for several hours, or as per the manufacturer's instructions, before applying the second coat. This drying time allows the render to set and provide a strong base for the second coat.

Applying the Second Coat:

> Apply a second coat of render in the same manner as the first coat, but finish it with a slightly smoother surface. Use a sponge or brush to smooth the render and remove any bumps or imperfections. ### Finishing the Render

Drying and Curing:

> Allow the render to dry completely for several days, protecting it from moisture and extreme temperatures. Avoid placing heavy objects on the wall or applying stress to the rendered surface during this time.

Sealing the Render:

> Once the render is fully dry, apply a sealer to protect it from moisture penetration and staining. The sealer will repel water, prevent cracking, and enhance the durability of the render.
