The wood's resin and damp can have organic qualities, which contain
nutrients for Cladosporium's –the black moulds- spores. Thereby
the growth can begin.
Wood often gather damp and is therefore an excellent underlay for the black mould spores affections. They establish everywhere and are very hard to treat.
To stop affections by black mould, all affections must be sanitized.
Treatment with Bensaltenside sterilizes all Cladosporium –all black mould, all spores- and disinfects the wood. The remains are rinsed off by the rain or can be washed off.
