Cut Edge Corrosion Repair Liskeard

Our company provides cut edge corrosion repair in Liskeard.

Premature failure of metal cladding roofing/exterior walling systems is caused by the cutting of the cladding to fit during installation and termed as "Cut Edge Corrosion". This cutting method leaves the metal edge exposed to the elements for prolonged periods and results in corrosion/rusting of the metal.

Delamination of the protective plastisol finish occurs in the form of a 'peel-back', due to the effect of rainwater running down the cladding causing wicking behind the unprotected metal.

Treating Cut Edge Corrosion:-

If not addressed quickly, the exposed cut edge begins rusting, and corrosion takes hold of the metal sheeting, causing even further delamination of the factory finish. Eventually, this causes leaks into the building, damage to the interior and very rapid deterioration of the metal cladding resulting in considerably increased maintenance costs, and in some instances complete roof classing replacement.

Using our priming systems, we can resolve the issue. The selected primer can be used in isolation or as part of a complete coating system. The treatment of cut edge corrosion begins with a comprehensive clean and a thorough wire brushing of the rust and then the removal of the loose or delaminated finish back to a sound edge.

Cut Edge Corrosion treatments include:

  • Urethane Primer MCU 126 to all prepared overlap areas.
  • Urethane Coating PU 846 colour matched to the existing coating.
