Avoid mould and moisture through proper ventilation
We always hear that problems with moisture and mould can be reduced by proper ventilation. We can only confirm this!
When showering, washing, drying clothes, cooking, even breathing, moisture is released into the air. And above all, more than you think.
In a 2-person household without ventilation, the humidity in the room can easily rise to 70%. In a family of 4 with animals in smaller flats, 100% humidity can quickly be reached at a room temperature of 22°.
The windows show the first signs of excessive humidity. They tarnish. This can be observed increasingly in the kitchen and bathroom. Especially on cold days, this can be observed more easily. Cold air and surfaces can absorb less humidity. From a surface temperature of 12°, the humidity condenses. The result is the formation of droplets on the window. The walls start to collect moisture.
If gypsum plaster in particular is exposed to moisture for a longer period of time, mould will form.
Proper ventilation can provide a remedy.
However, ventilation means opening the window wide, also called "shock ventilation". Ideally, you should open an opposite window in the neighbouring room to create a draught.
This is also more energy-saving than "tilting ventilation". When you ventilate the room, only the air is exchanged. The walls do not have time to cool down.
If the window is tilted for a long time, the air is only exchanged poorly and the walls and windows are cooled down considerably, which can even hide mould.
When to ventilate
Airing for 5 minutes after getting up, after showering, after cooking and before getting up can remove the humidity from the rooms.
In addition, you can get a digital or analogue hygrometer on Amazon.
You can place these in the living rooms as well as in the bathroom.
If you notice that the humidity is above 60%, simply ventilate for 5 minutes.
I hope these tips help you to manage your indoor humidity and mould problems.
