Mineral wall coating, made of common lime, easy to apply, with drying times which enable rapid use of the rooms in which it is applied. Due to its chemical nature, it does not form a film but hardens due to a chemical reaction with the substrate and, given its high alkalinity, it has greater resistance to mould compared to ordinary paint for interiors. It is characterized by high water vapour permeability so as to guarantee the breathability required to ensure dry walls and prevent condensation in environments subjected to high concentrations of steam such as kitchens and bathrooms. Its high breathability makes it ideal as a finishing product for dehumidifying systems. Thanks to its excellent filling properties, it can be applied with manual tools creating a thick coat with a good finishing level that is compact and easy to polish, distinguished by a variety of colour effects and undertones. It provides a low dust retention film that is friction-resistant.
