Fungi of all kinds – and thus also moulds – can be found practically everywhere. They perform numerous functions, including the decomposition of organic materials, which is why they play an important role in the cycle of nature. Moulds form networks of typical threads and tiny spores that are transported through the air.
Indoor mould becomes a serious problem when its concentration exceeds a certain level. It can then cause damage to furnishings, plaster and masonry and become dangerous to the health of the occupants. For these reasons, it should be removed as soon as its outgrowth is visible. The greatest danger for the spread of mould in one’s own four walls is too high humidity. This is because it needs no oxygen, no light and only a few nutrients to grow.
Experts estimate that there are around 250,000 types of mould. Of these, only a few are responsible for damage to the building fabric or health consequences for the occupants. Black, white and green mould are particularly common indoors. However, red and yellow species are also relevant.
If a mould finds sufficient moisture and food, it forms a cotton-wool or velvet-like coating on the nutrient substrate. Over time, this grows into large colonies of fungi. The respective fruiting body is responsible for the colouration. An exact determination of which mould it is, however, is only possible through an expert test by a specialist. Green mould has the widest distribution, but is less dangerous than the other species. Black mould is considered particularly aggressive to humans and animals.
If you find the typical stains of mould on walls or ceilings, you should immediately call in a specialist company like MVM AG. A specialist will expertly analyse the affected area and know the necessary technique for the long-term removal of the unwanted growth. Simply painting over the mould with standard wall paints will at best make it invisible for a while, but will not eliminate it.
We at MVM AG treat the infested areas professionally with a paint that is resistant to mould and is also used in hospitals, for example. This is the Bioni System Food, which was developed together with the renowned Fraunhofer Institute. The system, which contains neither fungiuides nor biocides, can be used wherever plaster and paint are load-bearing.
Colloidal silver is bound in the paint, which penetrates the cells of the fungus and destroys their membrane. As a result, it can no longer reproduce and dies. After treatment, Bioni System Food ensures lasting protection and long-lasting resistance.
Whether you have already been affected by mould or not – you can prevent an infestation or re-infestation yourself with simple methods. Get yourself a hygrometer and regularly check the humidity in all living spaces. It should be around 55 % to 60 % in the long term. The room temperature is also an important factor. In rooms used for domestic purposes, we recommend 20 °C, in the bedroom, in the kitchen and about 17 °C to 18 °C when you are away.
The third important factor is proper ventilation. The best way to do this is to ventilate several times for five to ten minutes, especially in bathrooms, kitchens and bedrooms. If this is not possible for certain reasons, a dehumidifier can help. Problematic exterior walls can generally be protected by painting them with Bioni System Food.
