What is Monocouche Render?
Monocouche render is a pre-mixed, cement-based render designed to be applied in a single coat. The word “monocouche” comes from French, meaning “single layer.” It is often used for creating a modern, coloured exterior finish on both residential and commercial properties.
It’s popular due to its ease of application and built-in pigmentation, meaning there’s no need to paint the surface afterwards. Once applied, it offers a clean, crisp finish that is both waterproof and breathable.

What is Silicone Render?
Silicone render is a thin-coat render made from flexible synthetic resins. It is often used in External Wall Insulation Systems (EWI) and applied in thinner layers than monocouche render. Silicone render is known for its flexibility, self-cleaning properties, and excellent water repellency.
It’s especially effective in areas with variable weather or where building movement may be an issue, as it resists cracking better than more rigid systems.

Key Differences Between Monocouche and Silicone Render
To help you choose between these two render types, let’s break down their main differences.

Water Resistance | Water-resistant but can absorb moisture over time | Water-repellent and breathable |
Maintenance | May require periodic cleaning | Self-cleaning, low maintenance |
Best For | New builds, properties with stable substrates | Renovations, properties with minor movement |
Cost | Lower material cost | Higher material cost, but more durable |

Frequently Asked Questions
Is monocouche render waterproof?
Monocouche render is water-resistant and protects against rain, but it is not fully waterproof. It is designed to allow walls to breathe, preventing moisture build-up inside the property.
Does silicone render need painting?
No – like monocouche render, silicone render is typically pre-coloured. However, it offers more colour flexibility than monocouche systems.
Which lasts longer – monocouche or silicone render?
Silicone render generally has a longer lifespan due to its superior flexibility and weather resistance. With proper care, both systems can last over 20 years.
Can monocouche render be used over existing render?
Not usually. It’s best applied directly to blockwork or an appropriate substrate. If you’re dealing with old or damaged render it will need to be removed and a base coat applied prior to the application of the monocouche base coat..
Our Verdict: Flexibility vs Efficiency
Both monocouche and silicone render have their strengths, and the best choice depends on your specific requirements. If you want a fast, attractive solution and your building is structurally sound, monocouche render is hard to beat. If you need extra flexibility, breathability, or live in a harsh weather area, silicone render might be worth the extra cost.
