Damp and the resin in wood have organic qualities and contain nutrients.
When Cladosporium –the black moulds- spores gets a hold on the
paling it gets the nutrition and water from the paling that it needs
to survive. The establishment of the most difficult affections has begun.
Fissures, gaps and joints in all parts of the palings become dirty and damp which provides even more nutrition to the black mould. The development speed increases and the affections are getting worse.
As long as there are any spores or remains of black mould left, the affections will continue to return. Sterilization of spores and black mould is necessary to get a clean surface without recurring affections. Bensaltenside is guaranteed to protect the paling for four years.
