Hydro Repellent (water-based)

Water Based solvent-free impregnation based on a silane/siloxane mixture emulsified in water. 

Penetrates deep into the stone and reacts with the silicate structure to form a durable, water-repellent polysiloxane network without impairing vapour permeability. Protects façades and stone surfaces from water and dirt absorption while allowing rapid drying during dry periods. Resistant to UV radiation, non-yellowing, and suitable for slightly damp substrates.
