Outdoor wall coating based on modified potassium silicate, adhesion promoters, inorganic pigments, marble slivers, quartz powder, stabilizing additives. The formulation based on silicates gives the product the following characteristics: breathability, light stability and weathering. After drying, Silicaf Intonachino reacts with carbon dioxide forming the colloidal silica which, combine with the support on which it is applied, consolidates it. The crystallization of the silica creates a microcrystalline structure that does not alter the porosity of the plaster and then its breathability. For all these characteristics and for the aesthetic effect very similar to that of the ancient colored plasters, Silicaf Intonachino is ideal for the restoration and the coating of buildings of considerable artistic interest. The product can still be used in all those cases where you do not want to remove the wall breathability.
