What are the properties of anti-mould paint?

An anti-mould paint protects the substrate from mould infestation. Here, it is not only functional, but also a fully-fledged renovation paint for ceilings and walls. Most anti-mould paints are also antibacterial. Mould needs moisture to grow. If an anti-mould paint is used to protect the substrate from mould infestation after the substrate has been renovated, it should be breathable, i.e. open to vapour diffusion. With an anti-mould paint that is open to vapour diffusion, residual moisture can diffuse out of the substrate and condensation on the surface into the wall. This reduces the “water” on the surface, especially in the area of thermal bridges.

What is the difference between the properties of an anti-mould paint and a paint with film protection?

An anti-mould paint contains biocidal active substances. These actively protect the substrate, i.e. the masonry, the wallpaper, the basement wall, from mould infestation. An anti-mould paint explicitly praises these properties as its essential function. An anti-mould paint is a biocide product.

In a paint with film protection, the surface of the paint, i.e. the paint film, is protected by active substances against possible mould infestation. A paint with film protection is not an anti-mould paint, but a “treated product” according to the Biocide Ordinance.
