FS DEEP IMPREGNATOR is a ready-to-use, solvent-based impregnator composed of silanes and siloxanes, designed to protect mineral and alkaline surfaces from water absorption. It penetrates deep into porous substrates, reacts with moisture to form a durable barrier, and retains the material’s breathability by allowing trapped vapors to escape.
The formula resists alkalis, dries tack-free, and can be applied even on slightly damp surfaces, making it ideal for long-term surface preservation.
