On the surface of the grout dirt and damp gets stuck. This mix supplies
the spores with nutrients. The affection becomes established and as
long as there are nay spores left or remains of old mould in the surface
pores, the affections will recur.
The rough surface of the grout gives the mould very good foot hold and
it grows fast. The growth develops fast and the affections become worse.
Renovating and further work might be necessary. Bensaltenside eliminates
this.
All mould spores –and therefore all mould affections and all growths-
are killed off by sterilization within 24 hours. The surface becomes
disinfected and makes any growth impossible. All affections are arrested
and the remains are rinsed off by the rain. Or by hand.
