Unicover EdgeProtect System

Cut edge corrosion occurs where the uncoated edges of coil-coated Plastisol sheets have been exposed to weathering. To combat this, Unicover’s EdgeProtect system has been developed to provide a cost-effective means of tackling cut edge corrosion by sealing and safeguarding corroded edges.

A high-performance product, when timed correctly this product is sure to extend the life of your cladding system and can also be used to stop roof leaks – helping to save on the potential cost of replacing cladding.

EdgeProtect incorporates a high-quality primer which exhibits superb adhesion onto prepared metal and existing coil coated finishes. A flexible butylene tape adds strength across the sheet edge which is then further reinforced with a fibre filled coating delivering a 20 year performance.

Part of the well-established Rust-oleum group, with over 40 years worth of experience in the industry, at Tor Coatings we’re proud to offer effective waterproofing solutions all over the nation. In addition, as leading providers of cut edge corrosion products, you can buy from us safe in the knowledge that you’ll receive high-performance products from a high-quality manufacturer time and time again.
