Why Does Black Mould Appear on Internal Walls?
To find out the causes of black mould on internal walls, we must understand what condensation is, and the conditions that combine to create it.
We cause condensation on a daily basis. Cooking, washing dishes, bathing, and even breathing all produce droplets of moisture. This build up of moisture is then released into the air.
Sadly, the air can hold only a certain amount of vapour. If the vapour is cooled, it turns into droplets of water, commonly called condensation.
Every home gets condensation at some time, usually when a lot of moisture or steam is produced and released. It is normal to find the windows misted up in the morning after a cold night.
Unfortunately, condensation spells a considerable deal of trouble for your internal walls, and can, in some cases, compromise structural integrity.
