ProGuard Exteriors were appointed to renovate and protect a large detached property in Egham, Surrey that was suffering from extensive render defects, flaking coatings and general weathering. The homeowners wanted a long-term solution that would restore the appearance of the home while helping protect against future cracking, water ingress and coating failure.

Overview

The property’s exterior had become tired, weathered and affected by years of exposure to the British weather. During the initial survey, several issues were identified across the external walls, including blown and hollow render, localised cracking, failing wall coating, discoloured surfaces, weathered mock Tudor timber features and faded fascia and soffit boards.

Although the majority of the render remained structurally sound, there were multiple isolated areas where the render had lost adhesion and required repair before any new coating system could be applied. Addressing these defects properly was essential to ensure the new finish would perform as intended and provide a long-lasting result.

Our Response

Following inspection, ProGuard Exteriors recommended a comprehensive programme of specialist render repairs, surface preparation and application of Andura Proflex Elastomeric Wall Coating in Polar White. The first stage involved carefully identifying and removing blown render sections back to a sound substrate before carrying out new render repairs to match the existing wall construction.

Because the property had a traditional textured render finish, our team used a specialist Tyrolean spray pot to recreate the original texture and blend the repaired sections into the surrounding surface. This helped ensure the repaired areas maintained a consistent appearance once coated.

All elevations were then cleaned, prepared and protected before the wall coating was applied. Surrounding areas including windows, doors, paving and other external features were carefully masked to protect them throughout the works.

Benefits Achieved

The finished project has restored a tired exterior suffering from render defects, flaking coatings and weathered detailing into a bright, clean and protected property exterior.

Flexible Protection: Andura Proflex was selected for its elastomeric formulation and ability to provide flexible protection to rendered surfaces.

Weather Resistance: The wall coating system helps protect the render against moisture penetration, water ingress and harsh UK weather conditions.

Vapour Permeable Finish: The coating system remains breathable while providing a protective exterior finish.

Why Use ProGuard Exteriors

For exterior renovation projects where render defects, cracking and coating failure are present, the preparation stage is just as important as the final coating system. ProGuard Exteriors carried out a full repair and preparation process before applying the new protective finish.

Detailed Property Assessment: The external walls were inspected to identify defects before the correct repair and coating approach was selected.

Specialist Repair Process: Blown render and cracks were repaired properly before coating, helping support the long-term performance of the system.

Texture Matching: The use of a Tyrolean spray pot allowed repaired textured render areas to be blended into the original finish.

Complete Exterior Package: Render repairs, wall coating, mock Tudor restoration and fascia and soffit painting were all included in the refurbishment.

Why It Matters

When a rendered property is affected by blown areas, cracked render, failing coatings or flaking masonry paint, simply decorating over the surface can reduce the lifespan of the new finish. By removing defective areas, repairing the render, matching the texture and applying a flexible elastomeric coating system, this Egham property now has a cleaner appearance and a more resilient exterior.

The completed transformation has restored the character of the detached home while providing a long-life coating system designed to protect the render and reduce future maintenance.
