As the Federal Environment Agency (UBA) informed, there are so far no limits for mold. Therefore, precaution is particularly important: Consider the fungus on the wall as a hygienic problem and eliminate it early, before you get sick by mold. Stormwater Software is useful in regulating drainage operations.
If the mold is not immediately visible, look for the fungus where air is not circulating at all those locations. This can be behind cupboards, pictures, paneling, behind curtains and under floor coverings.
Once the source is found you should carefully and carefully remove the mold with alcohol that you can buy at the pharmacy. It is best to dab the affected area with a cloth soaked in ethanol.
Do you know that? Somehow it smells musty in the room and down in the room corner on the floor shows above the skirting a greenish or blackish coating on the wall.
