ProGuard Exteriors completed an exterior wall coating and waterproofing project in Elmbridge, Surrey, restoring the appearance of a property’s rendered walls while addressing failing exterior coatings and providing additional protection against weather exposure. The refurbishment combined careful surface preparation, necessary render repairs, Andura Pro-Flex smooth colour wall coating and targeted Acrypol waterproofing to the front garage parapet wall.

Overview

This exterior refurbishment project was completed on a property in Elmbridge, Surrey, where the existing rendered walls required maintenance and a refreshed protective coating system. Sections of the previous exterior finish had started to deteriorate, with loose and flaking coating requiring removal before a new decorative finish could be applied.

The objective was to restore the appearance of the property while providing a durable exterior wall coating designed to reduce ongoing maintenance and help protect the rendered surfaces against further weather exposure.

Alongside the general wall coating works, particular attention was required at the front garage parapet wall. This exposed junction needed an additional waterproofing treatment to help prevent moisture tracking behind the newly applied wall coating and potentially affecting its long-term performance.

Following an assessment of the required works, ProGuard Exteriors specified a combination of surface preparation, necessary render repairs, Andura Pro-Flex smooth colour wall coating and Acrypol waterproof roof coating to address both the decorative and waterproofing requirements of the project.

Our Response

Before applying the new exterior coating system, our team carried out the necessary preparation works to ensure the existing rendered walls provided a suitable surface for application. The exterior was cleaned to remove surface contamination, while loose and flaking sections of the previous coating were carefully scraped away.

Where required, defective render areas were repaired to restore the underlying surface and provide a more consistent foundation for the new decorative coating. Completing these repairs before application was an important part of achieving a uniform finish across the existing rendered elevations.

Once the cleaning, scraping and repair works were complete, the walls were coated using Andura Pro-Flex smooth colour wall coating. This long-life exterior coating system was selected to create a fresh, consistent appearance while providing durable protection against everyday weather exposure.

In addition to the main wall coating works, ProGuard addressed the topmost section of the front garage parapet wall. Because water entering at this exposed junction could potentially track behind the new decorative coating, the parapet required a separate waterproofing treatment.

Acrypol waterproof roof coating was applied to seal the top of the garage parapet, providing an additional protective detail intended to help prevent water from penetrating behind the newly finished wall surfaces.

The combination of repaired render, smooth colour coating and targeted waterproofing delivered a coordinated exterior refurbishment focused on improving appearance while helping protect the completed works from further deterioration.

Final Specification

Exterior Wall Assessment: The existing rendered surfaces were assessed to identify areas requiring cleaning, coating removal and repairs before the new wall coating system could be applied.

Exterior Surface Cleaning: The walls were cleaned to remove surface contamination and prepare the existing rendered elevations for further refurbishment works.

Removal of Failing Coatings: Loose and flaking sections of the existing exterior coating were carefully scraped away to remove defective material before the new finish was installed.

Necessary Render Repairs: Localised render repairs were completed where required to restore defective surfaces and provide a sound, consistent foundation for the decorative wall coating.

Andura Pro-Flex Wall Coating: The prepared rendered walls were finished using Andura Pro-Flex smooth colour wall coating, creating a fresh and uniform appearance with a durable protective finish.

Front Garage Parapet Waterproofing: The topmost section of the front garage parapet wall was sealed using Acrypol waterproof roof coating to help prevent water tracking behind the new colour coating.

Additional Chimney Refurbishment Option: The project specification also included an optional treatment to the left elevation chimney, comprising cleaning, necessary repairs and matching Andura Pro-Flex coating, with scaffolding included if this additional work was selected.

Benefits Achieved

The completed refurbishment restored the appearance of the property’s rendered exterior while combining a durable decorative wall coating with targeted waterproofing at an important exposed junction.

Refreshed Exterior Appearance: The Andura Pro-Flex smooth colour coating provided a cleaner, more consistent decorative finish across the prepared rendered walls.

Repaired Render Surfaces: Necessary repairs addressed defective areas before coating, helping provide a more stable and uniform foundation for the completed finish.

Removal of Failing Material: Scraping away loose and flaking existing coating helped ensure defective material was removed rather than concealed beneath the new finish.

Long-Life Exterior Protection: The Andura Pro-Flex coating system was selected to provide a durable finish capable of helping protect the rendered walls against continued weather exposure.

Reduced Maintenance Requirements: The long-life wall coating helps reduce the need for frequent repainting and ongoing decorative maintenance compared with repeatedly refreshing failing exterior finishes.

Targeted Waterproofing Protection: Acrypol sealing to the garage parapet helps reduce the risk of moisture entering behind the new wall coating at this exposed junction.

Improved Kerb Appeal: The combination of repaired render, a smooth decorative coating and careful finishing has given the property a cleaner, refreshed external appearance.

Why Use ProGuard Exteriors

Exterior wall coating projects often involve more than simply applying a new decorative finish. Existing render defects, flaking coatings and exposed junctions must be considered carefully to help ensure the completed system provides the intended appearance and protection.

For this Elmbridge property, ProGuard Exteriors combined preparation, repairs, long-life wall coating and targeted waterproofing to deliver a more complete approach to exterior refurbishment.

Preparation-Led Approach: Exterior surfaces were cleaned and failing coating removed before the new Andura Pro-Flex system was applied.

Necessary Render Repairs: Defective rendered areas were addressed before the final coating to provide a more suitable surface for application.

Long-Life Coating Solutions: Andura Pro-Flex was selected to provide a durable smooth colour finish while reducing the need for regular decorative maintenance.

Attention to Waterproofing Details: Additional Acrypol treatment was incorporated at the front garage parapet to help prevent water tracking behind the new wall coating.

Coordinated Exterior Refurbishment: The project combined cleaning, repairs, decorative coating and protective sealing to address both the appearance and exposed details of the property’s exterior.

Why It Matters

When exterior coatings begin to flake or fail, simply covering the affected surfaces with another layer of paint may not adequately address the underlying preparation requirements. Removing loose material and repairing defective render before applying a new coating helps establish a more suitable foundation for long-term performance.

Equally important are the exposed architectural details where water can enter behind decorative finishes. Parapet walls are particularly relevant because their upper surfaces can be exposed to direct rainfall. Without suitable protective detailing, moisture may track into vulnerable junctions and affect adjacent wall finishes.

By combining Andura Pro-Flex smooth colour wall coating with Acrypol waterproofing to the front garage parapet, this Elmbridge project addressed both the decorative condition of the rendered walls and the need for additional protection at an exposed junction.

The completed result demonstrates how careful preparation, render repairs and targeted waterproofing can work together to create a refreshed, lower-maintenance exterior designed to remain protected against everyday weather exposure.
