If you’re planning an exterior renovation or looking for a finish that combines durability with sleek modern design, silicone render is one of the best choices available today. Over recent years, it’s become the preferred rendering option for homeowners, installers, and architects who want a long-lasting, weatherproof, and visually appealing solution.
In this article, we explore what makes silicone render stand out, how it works, and why it’s becoming a top choice for homes across the UK and beyond.
What Is Silicone Render?
Silicone render is a thin-coat, polymer-enhanced finish used to protect and decorate exterior walls. It contains silicone additives that make the surface flexible, highly water-resistant, and capable of staying cleaner for longer.
Unlike traditional sand and cement render, silicone systems are designed to be breathable and crack-resistant offering a finish that not only looks great but performs exceptionally well in all weather conditions.
Top Advantages of Silicone Render
1. Outstanding Weather Resistance
Rain, frost, humidity, or harsh sun silicone render is engineered to withstand it all. Its hydrophobic properties mean water beads and rolls off, instead of soaking into the wall.
2. Flexible and Crack-Resistant
One of the biggest frustrations with old render systems is cracking. Silicone render expands and contracts with the building, helping prevent unsightly fissures and ongoing repair costs.
3. Excellent Breathability
Moisture inside your home needs a way to escape. Silicone render allows vapour to pass through without letting external moisture in — reducing the risk of damp issues.
4. Stays Cleaner for Longer
Thanks to its self-cleaning qualities, dirt and debris find it harder to stick to silicone surfaces. A quick rinse now and then is often all that’s required to keep the finish looking fresh.
5. Huge Range of Colours
From crisp whites and modern greys to bold architectural tones, silicone render is available in hundreds of colours. Because the pigment is built into the material, fading is minimal.
Where Is Silicone Render Commonly Used?
Silicone render works well with a variety of substrates, including:
- External wall insulation (EWI) systems
- Brick and blockwork
- Masonry
- Concrete
- Renovated or older homes
- New build properties
Whether you want to upgrade a dated exterior or complete a contemporary build, silicone render provides a stylish and hard-wearing finish.
How Silicone Render Is Installed
A typical silicone render system includes:
- Preparation and cleaning
- Basecoat application and mesh reinforcement
- Primer layer
- Thin-coat silicone render
- Final texturing or finishing
Because silicone render is a specialist system, professional installation is highly recommended to guarantee longevity and performance.
Silicone Render vs Mineral Render
Feature | Silicone Render | Mineral Render |
Water Resistance | Excellent | Good |
Drying Time | Fast | Very fast |
Breathability | High | High |
Crack Resistance | Very high | Moderate |
Colour Range | Extensive | Limited |
Mineral render is often chosen for speed, but silicone render remains superior when it comes to long-term durability and colour stability.
Cost of Silicone Render
Pricing depends on property size, complexity, and whether it’s paired with external insulation. Typical UK prices range from:
- £60 to £100+ per m² including materials and labour
- Additional costs for scaffolding, detailing, or premium colours
Though it costs more upfront than basic render systems, it’s widely regarded as a cost-effective option long-term due to its durability and minimal maintenance needs.
Why Homeowners Are Switching to Silicone Render
Homeowners increasingly choose silicone render because it offers:
✔ A modern, clean, smooth finish
✔ Long-term weather protection
✔ A colour that lasts for years
✔ Reduced maintenance costs
✔ Resistance to cracks and algae growth
It’s a finish that not only enhances curb appeal but protects your home for years to come.
Silicone render is one of the most advanced and reliable exterior coating systems available today. With its impressive water resistance, flexible performance, and vast range of colours, it’s a smart choice for anyone wanting a durable and attractive finish.
