Edge peeling is a well-known phenomenon in the roof- and facade sector. It occurs on all types of coating systems, but mostly on the so-called plastisol coatings and especially on the obsolete systems. Edge peeling is often evident on the front sides of cladding where the applied coating is frequently exposed to humidity and contamination. Here, the front side of the product is relatively less protected, so that rusting can occur underneath the coating. This can result in a detached coating and extreme damage.
Where does this occur?
In 90% of the cases, edge peeling occurs on the roof where the roof cladding extends into the gutter. Here is where the most contamination occurs. The so-called cathodic action of the underlying zinc provides some protection, however without treatment, in many cases, it is already too late.
What risk do you run?
You run the risk of edge peeling damaging your cladding. Due to the capillary action of water (rising water), the problem escalates from bad to worse. Without correct treatment, the edge peeling will escalate into in large pieces being delaminated (large parts of the coating becoming detached). In many cases, replacement of the cladding or applying a new coating is then necessary.
Can it be prevented?
In many cases, correct and periodic maintenance can prevent edge peeling to a limited extent. The most common cause of edge peeling is thus incorrect or no periodic maintenance. Many end users have no idea of what is happening on the roof. During the installation of the cladding, the front sides can also be treated with a preventive coating.
