The cut edge corrosion to this metal profiled roof had already been treated with a cut edge corrosion system, which had begun to fail in multiple areas due to water becoming trapped between the overlapping roof sheets, which had been sealed with silicone sealant.

The difference between the two systems is quite apparent, as the Flexlap system is made from a specially hardened silicone, designed to resist environmental dirt pick-up as well as providing a much smoother finish.

It should be noted that the Liquasil cut edge corrosion system is designed by Building Surveyors who do not recommend that the gap between overlapping roof sheets is sealed. This allows any moisture that might be present to escape or evaporate naturally, which is how built-up steel profile roofs are designed to work.

The project was completed by Liquasil Approved Installers, HRC Industrial Cladding Ltd.
