The story of mould fungus forming on sealant materials.

Where does the mould fungus come from?

Spores of mould fungus are present everywhere in the air and therefore also on all surfaces. Through high humidity and lack of adequate ventilation the mould spores swell up and germinate radially to build a fungus network.
How does mould fungus spread?

The main factors are:

  • High humidity
  • Warmth and poor ventilation
  • Washing residues, soap etc.
Can a good silicone prevent this?

The greater number of all silicone sealant materials on the market are fungicidal, that is fungus retarding. All silicones of the B&N Products range (with the exception of a few products such as Tecniseal Food Grade etc.) are of this type.

When the fungus spores germinate the fungicide is taken up into the cell of the fungus and is then destroyed. At the same time the fungicide is gradually used up. A long-term effect can only be achieved with highly poisonous chemicals, these are, of course, prohibited by the legislators.

The Federal Health Ministry recommends a so-called spatial load limit. This upper limit must not be exceeded by fungicides, which are given off from the silicone joints. B&N Products keeps to these load limits and offers a sensible balance of good effectiveness and compatibility.

How does one prevent mould fungus forming?

The most effective, simplest and healthiest method is to deprive the spores of the possibility for growth.

Silicone joints should be rinsed after taking a shower, then dried with a cloth. The silicone joints should be cleaned with a normal household cleaner, rinsed and dried once a week. Also regular airing of the room cannot be over emphasised.

Joints contaminated by mould fungus must be treated with a massive chemical dose. Cutting out and renewal is the only permanent solution.
