We have spoken on several occasions about excess  humidity in the walls  and the resulting mold, a problem that can affect our homes especially when they are located in humid contexts and it is not possible to ensure adequate ventilation.

Over time, concrete walls end up  absorbing moisture from the ground  , which rises through them until it becomes visible through  patches of mold  . But mold growth on walls can also occur in apartments if they are not properly ventilated.

Usually when this problem arises we try to fix it with generic cleaning products, perhaps by repainting the wall. However, if the problem is not completely eliminated, it will only be a few weeks before the mold returns.

1. Eliminate moisture with talcum powder

Talc is an excellent ally against humidity and acts on walls in the same way as on shoes: it extracts and absorbs humidity.

Simply pour a little talcum powder on the walls, then rub with a cloth to work it into the walls. Repeat the process several times to make it even more effective in removing all traces of moisture.
