While it is easy to clean mould from smooth surfaces and windows, it is far more difficult to remove it from walls. But do you have to remove the entire mural if it has mould at the corners?
How to remove mould from murals
The first thing to do is to tackle the cause of the mould growth. If there is mould on a mural on an exterior wall, the mould may have been caused by the difference between the indoor and outdoor temperatures. The resulting condensation provides the ideal breeding ground for spores. If murals on an interior wall show traces of mould, it may be the sign of a bigger problem. In the past, there may have been a burst pipe or water damage that was not allowed to dry out properly. If this is the case, the mural must unfortunately be removed completely so that the cause can be investigated. If you do intend to remove mould from a mural in the first instance, you must wear a facemask and gloves. The stains can be carefully removed with a damp cloth and some strong rubbing alcohol. But be careful - too much of it could damage the print and reduce the colour quality. And of course it is best if the mould does not appear in the first place. More frequent ventilation and hanging damp laundry outdoors are effective ways of keeping your home mould-free.
