Water-repelling impregnation liquid, with silicone-based resins and solvents. It has high resistance to alkaline environment and high penetrating ability (micro technology). It does not form a surface film, does not shine and remains clear, without yellowing. Protects the unpainted plaster from weathering and the concrete from carbonation. It ensures 100% breathability and complete water repellency for at least 10 years, when applied in two coats using the ‘wet on wet’ application method, on any white or colored marble-based plaster wall surfaces or concrete surfaces.
