Basecoat & Silicone Render Systems
Built for Strength and Longevity
When your project demands more than a decorative finish, our full Basecoat and Silicone Render System provides a technically superior solution – reinforced, crack-resistant, and built to perform for decades.
A basecoat and silicone render system is a two-stage process. The first stage involves applying a polymer-modified basecoat reinforced with an embedded fibreglass mesh – creating a mechanically strong, impact-resistant layer that bonds firmly to the substrate. The second stage is the application of a decorative silicone topcoat in your chosen colour and texture.
This combined system is more robust than a silicone-only finish and is the preferred solution where walls are uneven, where the existing surface needs significant repair, or where a higher level of performance is required — such as new-build projects, EWI installations, or full external refurbishments.
All systems are installed to BBA-certified and PAS 2030 standards, using manufacturer-approved materials from leading suppliers.
Advantages of a full Basecoat & Silicone System
Reinforced fibreglass mesh provides structural strength and impact resistance
Eliminates cracking caused by substrate movement
Suitable for poor, uneven or failing substrates
Compatible with external wall insulation (EWI) boards
Flexible silicone topcoat for weather and UV resistance
Available in hundreds of colours and grain textures
Longer service life than basecoat-only or cement render systems
Installed to BBA and PAS 2030 standards
Our 5-Stage Render System Installation
Stage 1Preparation
We strip any loose, failing or contaminated material from the substrate. Walls are cleaned, cracks filled, and a bonding agent or primer applied as required.
Stage 2Reinforced Basecoat Layer
A polymer-modified basecoat is applied to the prepared surface. Before it sets, alkali-resistant fibreglass mesh is embedded across the full area — providing tensile strength and preventing cracking.
Stage 3Primer Coat
A colour-matched primer is applied over the cured basecoat to ensure consistent colour and optimal adhesion for the silicone finish.
Stage 4Silicone Topcoat
The silicone render is hand-applied in the chosen grain and colour. Multiple quality checks are carried out throughout application.
Stage 5Finishing & Quality Assurance
Edges are detailed, beads and trims are checked, surrounding areas cleaned down, and a final inspection carried out to manufacturer and BBA certification requirements.
When is a full Basecoat System the right choice?
We recommend the full basecoat and silicone system for new-build projects, properties undergoing EWI installation, homes with significantly cracked or unstable render, refurbishments where a long service life is the priority, and any project where the substrate condition is poor or uneven.
For properties with a sound existing substrate that simply needs a refreshed finish, a silicone-only render may be more cost-effective. Our team will assess your property and recommend the right solution.
