Potassium silicate is used both in paints and in restoration for the significant advantages it offers during application. Silicate paints are recommended for their breathability and are a valid alternative to lime-based paints. Silicate paints, due to their high permeability, are used in the restoration of damp buildings. They are called silicate paints because they use potassium silicate as a binder, and their fixing action is due to the reaction with atmospheric carbon dioxide.
