Metal is inorganic in its pure form, since it does not contain any organic
materials. The metal surface gains organic qualities when dirt and damp
gathers on it.
Metal facings and roofs have for long time been difficult to clean.
This has mostly been a problem for industrial buildings, due to their large metal surface areas, resulting in costly and time consuming repairs. With moisture and nutrients present, the fungus has had all the necessary conditions to establish itself on the metal.
Fungus spores on metal develop fast. To kill all spores and fungus –by sterilization- treatment with Bensaltenside is necessary. The treatment stops all growth within 24 hours.
The metal surface becomes disinfected giving a long-time protection which is guaranteed to keep affections and growths at bay for a minimum of four years. The protection time is often much longer than that.
