In which to choose the breathable and in which the washable
The breathable products are always indicated above all in humid environments such as kitchens and bathrooms because they do not create impermeability to steam.
The washable ones are suitable for interiors in all other cases and for exteriors, but remember that they create vapor barrier and are therefore not recommended in damp environments.
Better than natural lime or natural resins
The biocompatible architecture favors natural paints because they pollute the environment less and are composed of non-toxic substances for humans.
These paints are based on lime putty or natural resins and sometimes use casein as a fixative.
