Black discolouration on a ceiling is usually more than an aesthetic problem: it is a sign of increased moisture loads, condensation or a building-related limitation. Therefore, do not treat only the surface; first understand the cause. Within a careful approach, a vapour-permeable, mould-resistant finish provides breathing room.
Understand the cause first
Black mould generally develops on surfaces that remain damp for long periods — often in bathrooms, bedrooms, sanitary areas or beneath colder parts of a building. The causes are condensation, thermal bridges, limited air circulation, penetrating damp or a combination of these. A sustainable approach therefore begins with a proper assessment: is there a structural moisture load, insufficient ventilation, a thermal bridge or a leak?
Cleaning and finishing as a system
Where there is visible growth, a system approach is important: first clean and prepare correctly, then apply a technically suitable finish. A new layer performs well only on a suitable, correctly treated substrate. In this context, Inducoat Fungi is relevant as a paint with a dry paint film that is resistant to mould — the property relates exclusively to the finishing layer itself, not to the room.
Vapour-permeable: breathing room under difficult conditions
Particularly where there is an increased moisture load or a building-related limitation that cannot be resolved immediately, Inducoat Fungi provides breathing room within the paint system thanks to its vapour-permeable properties. In damp rooms, it is important that the finish is compatible with the substrate in terms of building physics; a vapour-permeable system offers more scope in this respect than an overly impermeable finish. It remains no complete solution: paint does not eliminate a ventilation problem, thermal bridge or leak. Its value lies in the combination of a vapour-permeable finish and a mould-resistant dry paint film, within a broader approach to moisture and maintenance.
