Easy Maintenance

Silicone render is easy to clean and maintain. It repels dirt and can be easily washed with water, keeping your walls looking fresh and clean.


Silicone render is flexible and can accommodate the natural movement of the building without cracking or peeling.


With proper installation and maintenance, silicone render can last up to 25 years, providing long-term protection and beauty to your home.

A Step by Step Guide to Applying Silicone Render

Prepare the Surface

Before applying silicone render, it’s crucial to prepare the surface properly. Start by cleaning the walls to remove any dirt, dust, or loose particles. Use a pressure washer or a stiff brush and water to ensure a clean and smooth surface. If there are any cracks or imperfections, fill them with a suitable filler and allow it to dry completely.

Once the surface is clean and dry, apply a suitable primer to enhance adhesion and ensure a strong bond between the render and the wall. Follow the manufacturer’s instructions for the specific primer you are using. Allow the primer to dry completely before moving on to the next step.

Mixing the Silicone Render Carefully

Next, use a clean bucket and mix the render with water according to the recommended ratio. Stir the mixture thoroughly until it reaches a smooth and consistent texture. Avoid overmixing, as it can introduce air bubbles into the render.

Apply the Base Coat and the Topcoat

Using a stainless steel trowel, apply a thin and even base coat of silicone render to the prepared surface. Start from the bottom and work your way up, ensuring complete coverage. Use a straight edge to level the render and remove any excess. Allow the base coat to dry according to the manufacturer’s instructions.

Once the base coat is dry, apply the topcoat of silicone render using the same technique as the base coat. Ensure an even and smooth application, paying attention to any decorative finishes or textures you desire. Use a trowel or spatula to achieve the desired finish. Allow the topcoat to dry completely.

Finishing Touches

Inspect the applied silicone render for any imperfections or inconsistencies. Smooth out any rough areas or unevenness, and pay attention to corners, edges, and joints. This helps to ensure a seamless finish. Allow the render to cure and dry completely before painting or applying any additional coatings.
