Silicone Render Specialists in Plymouth, Devon & Cornwall

Why Choose Silicone Render?

Silicone render is a polymer-modified exterior render system that incorporates silicone into the mix, producing a finish that is simultaneously weather-resistant and vapour-permeable. The silicone component makes the surface hydrophobic, causing water to bead and run off rather than soaking in, while the render itself remains open enough to allow the wall to breathe. In a coastal climate like Devon and Cornwall's, where wind-driven rain is a constant challenge, silicone render is the modern benchmark for external wall protection.

Riley's Pro Trowel supplies and applies full silicone render systems across Plymouth, Devon, and Cornwall. We work on residential re-renders, new builds, and commercial facades. Our Exmouth Development project demonstrates the complete system: external render carrier board, reinforcing fibre mesh basecoat, and pre-tinted silicone topcoat delivering an exterior finish that will require no painting for years.

Exmouth Development: Full Silicone Render System

The Exmouth Development project is a strong example of a complete silicone render system delivered by Riley's. The package comprised an external render carrier board providing a stable and level base, a full silicone render system with reinforcing fibre mesh embedded in the basecoat for crack resistance, and a pre-tinted silicone topcoat in the client's specified colour. The pre-tinted topcoat eliminates the need for painting, retaining its colour without fading, and the silicone system provides robust protection against Exmouth's coastal exposure. The result is an exterior that looks exceptional and performs as well as it looks.

Bartford Beach House: Black Silicone Render

At Bartford Beach House near Widemouth Bay in Cornwall, Riley's applied a black silicone render to the exterior of this luxury coastal property. The contemporary architecture demanded a clean, dark finish that would complement the building's design and withstand the Atlantic coastal exposure. Silicone render in a deep colour requires careful selection of product and finish to prevent differential drying and uneven colour. Riley's delivered a consistent, striking result that is as functional as it is architectural.

Silicone Render Advantages

• Hydrophobic: water repels off the surface rather than soaking in
• Vapour-permeable: walls can still breathe while repelling liquid water
• Through-colour: no painting required, colour integral to the topcoat
• Flexible: accommodates minor building movement without cracking
• Algae and mould resistant, performs particularly well in coastal and humid environments
• Wide colour range: extensive palette with custom matching available
