Technical Case Study: Protecting Canterbury Retail Unit with Delcote 25

Established Expertise in Roof Refurbishment Sprayzone was recently appointed to complete a comprehensive roof sheet refurbishment at Wincheap Retail Park in Canterbury. The project involved a large retail unit formerly occupied by Mothercare, requiring essential restorative works prior to being handed over to new tenants, Next and Costa Coffee.

The Challenge: Extensive Deterioration and Corrosion Upon initial survey, the existing metal roof was showing significant signs of age and failure. The original coating had begun extensive delamination, and critical cut-edge corrosion was evident across the roof sheets. If left unaddressed, these issues would have compromised the structural integrity of the building and detracted from its overall aesthetic appeal during the rebranding process.

The Solution: High-Performance Restoration Coating To provide a long-term, cost-effective alternative to a complete roof replacement, the Delcote 25 system was identified as the most suitable technical solution. This high-performance liquid coating is renowned for its exceptional water repellency and robust corrosion resistance.

As Manufacturer Approved Applicators, the Sprayzone team managed the full application process, which included:

• Thorough Preparation: Cleaning and preparing the existing metal substrate to ensure optimal adhesion.
• Edge Protection: Application of Seamsil to address and encapsulate cut-edge corrosion.
• Expert Application: Precision spraying of the Delcote 25 system in strict accordance with manufacturer specifications.

The Outcome: 25-Year Long-Term Security Completed over a seven-week duration, the project has successfully addressed all existing delamination and corrosion concerns. By opting for restoration rather than replacement, the client avoided significant material waste while securing the unit’s weather resistance and aesthetic finish.

Most importantly, as a specialist approved partner, Sprayzone was able to provide the client with long-term peace of mind, as the system carries a manufacturer-backed 25-year warranty.

Key Project Benefits:

• Extended Asset Life: Effectively halted corrosion and prevented further metal deterioration.
• Minimal Disruption: Restorative work was completed efficiently without the logistical challenges of a full roof strip and replacement.
• Cost-Effective: Provided a professional, durable finish at a fraction of the cost of new installations.
• Guaranteed Protection: Secured a 25-year assured performance guarantee.
