What is Cut Edge Corrosion?

Cut edge corrosion is weather damage that occurs to the edge of a metal cladding sheet. These metal sheets come factory coated with a number of protective layers. However, when sheets are cut on-site to fit the specific dimensions of a commercial property, factory fitted protection is often lost and the edge becomes exposed to the elements and at risk of under and topside corrosion.

Corrosion commonly starts as edge peel at the cut edges of the metal sheet. It develops through normal weathering, mainly on roofs, and rapidly accelerates at the sheet overlap as a result of capillary held rainwater which causes underside corrosion.

Edge corrosion is a progressive problem and, if neglected, can develop away from the cut edge, destroying the weather-sealed lap joint and gutter overhang. Early detection and effective treatment prevents costly future sheet replacement and dilapidations.

Giromax® Edgecoat allows you to preserve the cut edge joint protection, without disturbing the existing fittings and sheets. It provides a strong, flexible external joint that remains unaffected by UV, weather and temperature extremes for up to 15 years.

Instructions for Use

Giromax® Edgecoat has been developed against a background of decades of experience in roof refurbishment and repair and is designed as a two stage application. Fully moisture tolerant, Giromax® Basecoat quickly cures to allow a follow-on installation of Giromax® SE Sealant and Giromax® Edgecoat. ​For more information on application, training and our products, please don’t hesitate to get in touch.


Moisture Tolerant Cut Edge Corrosion Solution

Giromax® Edgecoat outperforms traditional silicone based, cut edge corrosion coatings by providing an advanced solution. Through the use of laminar flake technology, this not only treats corrosion, but it also encapsulates and prevents further water damage.

Best of all, the polyurethane hybrid system can be applied in wet conditions without sacrificing performance or effectiveness. This reduces downtime and project delays when rain, dew and damp might traditionally cause disruption.
