Organic materials do not exist in pure metal. Organic qualities arise
when the surface gets exposed to damp and dirt –which supplies
the black mould with nutrients. Difficult affections grow.
New metal can last for decades if clean. When exposed to weather and wind, dirt particles and damp gets bound to the surface, which gives the spores nutrients. The mould starts to corrode the metal rapidly, resulting in costly and time consuming repairs.
Remains of black mould and mould spores in the surface pores enable the affections to recur as long as are any remains left. Sterilizing and disinfection with Bensaltenside removes all spores and all black mould within 24 hours.
Thereafter the metal is protected for four years. Guaranteed. Often it is longer than that.
