ProGuard Exteriors recently completed a large exterior wall coating project in Cambridge for a detached property that had begun to show significant signs of age and deterioration. The homeowners contacted us after noticing extensive cracking throughout the existing render, along with areas of flaking and peeling paint.

Overview

The property was a large detached home in Cambridge where the existing rendered finish had become tired, cracked and weathered after years of exposure to the British weather. Although the underlying sand and cement render remained structurally sound in most areas, the external finish was deteriorating and required ongoing maintenance.

The homeowners were also planning to invest in new windows, so they wanted a long-term exterior coating solution that would refresh the appearance of the home while providing lasting protection against future cracking and weather damage.

Our Response

After surveying the property and discussing the available options, ProGuard Exteriors recommended Andura Proflex, a high-performance elastomeric wall coating system designed for rendered and masonry surfaces. Unlike standard masonry paint, Andura Proflex remains flexible after application, allowing it to accommodate minor movement within the substrate and help prevent hairline cracks from reappearing.

A full preparation programme was carried out before coating. This included pressure cleaning the exterior surfaces, repairing visible cracks, protecting windows, doors, soffits, paving and surrounding areas, and then spraying the property with Andura Proflex in Pure Brilliant White to achieve a consistent finish and correct coverage across the large elevations.

Final Specification

Pressure Cleaning: The entire exterior surface was pressure cleaned to remove dirt, debris, organic growth, surface contaminants, loose paint and weathering deposits.

Crack Repairs: Visible cracks were opened, prepared and repaired using suitable repair materials to create a stable substrate before coating.

Protection and Masking: Windows, doors, soffits, paving and surrounding areas were fully masked and protected to ensure a clean professional finish.

Andura Proflex Application: The property was sprayed with Andura Proflex elastomeric exterior wall coating in Pure Brilliant White.

Benefits Achieved

The completed project delivered a fresh modern appearance while providing a flexible and protective coating system designed for long-term performance.

Crack Resistance: The elastomeric properties of Andura Proflex help prevent hairline cracks from reappearing through the finished coating.

Weather Protection: The coating creates a durable protective barrier against rain, frost, UV exposure and environmental pollution.

Breathable Finish: The system helps protect against water ingress while remaining vapour permeable, allowing moisture to escape from the wall structure.

Lower Maintenance: The completed coating reduces the need for regular repainting and ongoing maintenance associated with traditional masonry paint.

Improved Appearance: The Pure Brilliant White finish gave the property a bright, clean and modern look that complemented the homeowners’ plans for new windows.

Why Use ProGuard Exteriors

For exterior wall coatings to perform properly, preparation is one of the most important stages of the project. ProGuard Exteriors carried out a full inspection, cleaning, crack repair and protection process before applying the coating system.

Detailed Survey: The property was assessed before work began so the right coating system could be recommended.

Thorough Preparation: Cleaning, crack repairs and masking were completed before coating to support adhesion, performance and finish quality.

Professional Spray Application: Andura Proflex was sprayed across the exterior to provide consistent coverage and the correct film thickness for long-term performance.

Long-Term Focus: The system was selected to improve appearance while helping protect against cracking, moisture and future weather damage.

Why It Matters

Rendered properties throughout Cambridge and the surrounding areas can suffer from hairline cracking, flaking paint, staining, discolouration and water penetration when traditional painted finishes begin to fail. If moisture enters through cracks, deterioration can accelerate and lead to larger repair requirements in the future.

By repairing the cracks properly and applying Andura Proflex, this Cambridge property now benefits from a flexible, high-performance wall coating system designed to withstand the challenges of the UK climate for many years to come.
