A Growing Problem

Like most warehouses in Mexico, this building was fitted with a metal roof. Although the building was less than 10 years old, the metal roof was already moderately to severely corroded, and getting worse by the year.

The building owners had already attempted to address the solution using acrylic coatings, but all had failed to stop the corrosion. The owners feared that the only option left was to replace the entire roof - an expensive, lengthy process that would cause significant disruption to the operations of the home appliance company that occupied it.

When CPA approached our approved applicator Ingeniera Para Concreto for a potential solution, GE Enduris roof coating was recommended to stop the corrosion and protect the roof.

A Major Application

Applying Enduris was a major undertaking, with plenty of challenges. At 880,000 sq ft, it was a huge roof, and the extent of corrosion were significant.

Metal expands as temperatures rise, so it required a solution that could accommodate significant expansion. GE Enduris roof coating is permanently flexible, allowing it to expand and contract with the roof.

The project also included hundreds of thousands of screw heads, all that needed to be effectively treated using GE Enduris roof coating in a time-consuming process. Ingeniera Para Concreto handled the application.

The contractors were able to work all year round. Unlike other sealants, GE Enduris roof coatings are rain ready in as little as 30 minutes – allowing the team more flexibility to continue application throughout the rainy seasons.

With the coating process completed, the substrate was fully protected against oxygen diffusion and water penetration, and further corrosion was averted

Long Term Performance and Peace of Mind with GE Silicones Sealants

The restoration project was successfully completed in April 2020 – allowing CPA to avoid replacement, while helping to extend the lifespan of the existing roof, and the building, for the foreseeable future.

Using GE Enduris roof coating also allowed the occupants to realize benefits to the working environment inside the building. Coating the metal roof in white color resulted in a significant reduction to the temperature highs of the interior, making it more comfortable for those working inside.

As part of the project, we supplied a full 10-year materials and labor warranty, providing the client with a decade of security and peace of mind in their investment.

Project Overview

The CPA warehouse in Mexico, totaling 880,000 sq ft, was restored using GE EndurisTM 100% silicone roof coating. Severe corrosion affected the metal roof despite being less than 10 years old. Previous acrylic coatings had failed to prevent degradation.

Application Details

• Extensive surface preparation and treatment of thousands of screw heads
• Coating applied directly over existing metal surfaces, accommodating expansion
• Applied by Ingeniera Para Concreto, a certified applicator

Key Benefits

• Enduris coating is permanently flexible and rain-ready in 30 minutes
• Enabled year-round application, even during the rainy season
• Delivered full oxygen and moisture barrier to arrest corrosion

Outcomes

• Project completed in April 2020, avoiding expensive roof replacement
• Improved thermal comfort inside the facility with a white reflective coating
• 10-year materials and labor warranty provided

Conclusion

The GE EndurisTM coating system extended the roof’s life, improved building performance, and offered long-term peace of mind in Mexico’s challenging environment.
