Everything You Need to Know About Silicone Render — From Your Local Experts at Rains Plastering Ltd

At Rains Plastering Ltd, we specialise exclusively in rendering, with a strong focus on silicone render systems. Based locally and proudly serving the community, we understand the unique demands of British weather and building styles — and that’s why we recommend silicone render as the go-to solution for durable, high-quality external finishes.

If you’re considering rendering your property, you’ve probably got questions about silicone render. Don’t worry — we’ve put together this guide to explain everything you need to know, straight from the experts who live and breathe rendering every day.

What Is Silicone Render?

Silicone render is a modern, high-performance external finish that offers excellent weather resistance and breathability. Unlike traditional cement or acrylic renders, silicone render contains silicone resins which give it water-repellent properties while allowing moisture vapour to escape. This means it protects your walls from rain without trapping damp inside.

Why Choose Silicone Render?

There are plenty of reasons we favour silicone render for most of our projects:

• Weatherproof & Breathable: Silicone render acts as a barrier against rain, while still allowing the building to breathe — crucial for preventing damp and mould, especially in the UK’s often wet climate.

• Durable & Long-Lasting: It’s tough against the elements and generally requires less maintenance than traditional render, lasting 10+ years when applied correctly.

• Low Maintenance: Thanks to its water-repellent properties, dirt and algae are less likely to stick, meaning it keeps its fresh appearance for longer.

• Flexible & Crack-Resistant: Silicone render moves with the building, reducing the chance of cracks developing over time.

• Aesthetic Options: Available in a wide range of colours and finishes, silicone render can be tailored to suit any style, from modern builds to traditional homes.

How Does Silicone Render Compare to Other Renders?

Traditional cement renders are more porous and less flexible, making them prone to cracking and water ingress over time. Acrylic renders offer colour options but aren’t as breathable, which can lead to damp issues. Silicone render provides a perfect balance — waterproof yet breathable, strong but flexible.

Can Silicone Render Be Applied Over Existing Surfaces?

In most cases, yes. However, if you have an old pebble dash or poorly bonded render, the surface may need preparation such as hacking back to the brickwork before applying silicone render. We always conduct a site assessment to recommend the best approach and ensure a long-lasting finish.

What Does the Application Process Involve?

We work exclusively with EWI (External Wall Insulation) supplies for our silicone render projects, ensuring we use top-quality materials. The process typically involves:

1. Preparing the surface (cleaning, repairing, and if necessary, removing old render).

2. Applying a base coat and reinforcing mesh to strengthen the render.

3. Applying the silicone render top coat in your chosen colour and finish.

Scaffolding is usually needed for a safe and efficient application, especially on multi-storey properties.

How Much Does Silicone Render Cost?

Costs vary depending on the size and condition of your property, but silicone render tends to be a premium option reflecting its quality and durability. We’re happy to provide detailed, no-obligation quotes after a site visit so you know exactly what to expect.
