Mould – Is there a rule when mould spores turn into mould?

Geposted am | Mai 16, 2010

Yes, at least there is an indirect rule!

Whenever dampness hits and settles on a walls surface it becomes vulnerable for mould growth. Of course mould won’t grow from humidity and heat in your kitchen after you cooked a hot meal! But if this case is quiet frequent and the dampness has no chance to dry a possible danger might arise by that situation!

The dew point is applicable for condensation of humidity. The dew point is the temperature when condensation just starts. So if the room temperature is too cool to keep the humidity up in the air it starts settling down on the walls surface.

In case you’re having trouble with contamination by mould call a specialist to get a dew point profile created. By its result you will know if more heating or a better insulation would help or if this is only a temporary phenomenon.

Actually there are only two possibilities to get a balance between temperature and air humidity: For a start, we can make sure that our flats walls get warm enough. Plus there has to be an exchange from high humidity to drier air.

Radiant heating is able to warm up cool walls but solar energy does also help here. Clever airing will exchange high humidity to much drier air.

The rule says: Damp walls are either caused by condensation or capillary rising damp from the inside.
