ProGuard Exteriors completed a full exterior silicone rendering transformation in Bicester, Oxfordshire, replacing the property’s existing sand and cement render with a modern rendering system designed to provide a durable, weather-resistant finish. The refurbishment involved completely removing the old render, installing EWI Pro Premium Basecoat with reinforced mesh throughout, and finishing the external walls with a premium silicone render topcoat in Sandstone.

Overview

This exterior rendering project was completed on a property in Bicester, Oxfordshire, where the existing sand and cement render was to be fully removed and replaced with a new rendering system. The aim was to restore the external walls with a fresh, contemporary finish while providing improved surface stability and long-term protection against everyday weather exposure.

Rather than applying another decorative coating over the existing sand and cement render, the project involved removing the previous material entirely. This allowed the team to prepare the external walls for a new basecoat and reinforced mesh system, establishing a suitable foundation for the final silicone render.

The selected specification combined EWI Pro Premium Basecoat, reinforced mesh throughout and a premium silicone render topcoat in Sandstone. This approach was designed to create a strong, stable rendering system, minimise the risk of future cracking and achieve a clean, consistent exterior appearance.

Our Response

ProGuard Exteriors began by completely removing the property’s existing sand and cement render. Stripping away the old material was an essential part of the refurbishment, allowing the external walls to be prepared for the new rendering system rather than simply covering the previous finish.

Once the existing render had been removed and the walls were ready, our team installed EWI Pro Premium Basecoat with reinforced mesh throughout. The reinforced basecoat created a strong and stable foundation for the final render application, helping minimise the risk of future cracking while supporting a consistent finish across the property.

The reinforced mesh was incorporated throughout the basecoat system, providing additional reinforcement beneath the final decorative layer. This preparation stage was particularly important in creating a suitable surface for the new silicone render topcoat.

Following completion of the reinforced basecoat, the team applied the premium silicone render topcoat in Sandstone, the colour selected for this project. The finish provided the property with a fresh, modern appearance while offering weather resistance and a durable, low-maintenance external surface.

By replacing the existing sand and cement render with a complete new rendering system, ProGuard Exteriors delivered a refreshed exterior that combines careful preparation, reinforced basecoat protection and a contemporary Sandstone silicone render finish.

Final Specification

Complete Removal of Existing Render: The old sand and cement render was fully removed from the property to allow the external walls to be prepared for a replacement rendering system.

External Wall Preparation: Following removal of the existing render, the walls were prepared to provide a suitable surface for the installation of the new reinforced basecoat system.

EWI Pro Premium Basecoat: EWI Pro Premium Basecoat was applied to the prepared external walls, creating a strong, stable foundation beneath the final silicone render topcoat.

Reinforced Mesh Throughout: Reinforcing mesh was incorporated throughout the premium basecoat system to help improve surface stability and minimise the risk of future cracking.

Premium Silicone Render Topcoat: Once the reinforced basecoat was ready, a premium silicone render topcoat was applied to create the final protective and decorative exterior finish.

Sandstone Render Colour: Sandstone was selected as the final silicone render colour, giving the property a fresh, contemporary and consistent exterior appearance.

Benefits Achieved

The completed installation transformed the property’s exterior by replacing the previous sand and cement render with a new reinforced rendering system and premium Sandstone silicone render finish. The refurbishment improved the appearance and stability of the external wall surfaces while providing durable protection against the elements.

Complete Exterior Render Renewal: Removing the existing sand and cement render allowed the property to receive a new rendering system rather than another coating over the previous surface.

Improved Surface Stability: The EWI Pro Premium Basecoat and reinforced mesh created a stronger, more stable foundation beneath the decorative silicone render.

Reduced Risk of Future Cracking: Incorporating reinforcing mesh throughout the basecoat helps minimise the risk of future cracking and supports the stability of the completed render system.

Modern Sandstone Finish: The premium silicone render topcoat refreshed the external walls with a clean, contemporary appearance in the chosen Sandstone colour.

Long-Term Weather Protection: The silicone render finish was selected to provide durable weather resistance and help protect the external walls against continued exposure to the elements.

Low-Maintenance Exterior: The premium silicone render provides a durable decorative surface designed to reduce the need for frequent exterior maintenance.

Enhanced Kerb Appeal: Replacing the old render with a consistent Sandstone finish gave the property a refreshed, more modern exterior appearance.

Why Use ProGuard Exteriors

A full exterior rendering refurbishment requires careful preparation and the correct application of each stage of the rendering system. Removing the previous render, preparing the underlying walls and installing a reinforced basecoat are all important steps before applying the final decorative finish.

For this Bicester property, ProGuard Exteriors completed the refurbishment from the initial removal of the existing sand and cement render through to the final Sandstone silicone render application.

Complete Render Replacement: The existing sand and cement render was fully removed, allowing a new rendering system to be installed directly onto the prepared external walls.

Premium EWI Pro Materials: EWI Pro Premium Basecoat was selected as the foundation for the new rendering system, providing a stable surface for the final silicone render.

Reinforced Basecoat Installation: Mesh reinforcement was incorporated throughout the basecoat system to support surface stability and help minimise the risk of future cracking.

Premium Silicone Render Finish: The final Sandstone silicone topcoat combined a clean modern appearance with the practical benefits of a durable, weather-resistant exterior finish.

Start-to-Finish Refurbishment: The project combined old render removal, wall preparation, reinforced basecoat installation and silicone render finishing as part of a complete exterior transformation.

Why It Matters

When replacing an existing sand and cement render finish, the preparation beneath the new surface is just as important as the final appearance. Installing a new decorative coating over the previous render would not provide the same opportunity to prepare the external walls and introduce a fully reinforced replacement rendering system.

By completely removing the old render and installing EWI Pro Premium Basecoat with reinforced mesh throughout, ProGuard Exteriors created a stable foundation designed to support the final finish and minimise the risk of future cracking.

The premium Sandstone silicone render topcoat completed the transformation, providing a clean, contemporary exterior with durable weather resistance and reduced maintenance requirements.

This Bicester project demonstrates how a full rendering refurbishment can refresh the appearance of a property while providing a reinforced, long-lasting exterior finish designed to protect the walls against the elements for years to come.
