HMK S731 Silane Impregnator is a ready-to-use penetrating sealer for natural stone, concrete, and unglazed brick. The silane-based formula absorbs into the material to reduce water and dirt absorption without forming a surface film.
HMK S731 keeps treated surfaces vapor permeable, so moisture can escape instead of becoming trapped below the surface. It is used on interior and exterior stone and masonry where water resistance, low appearance change, and freeze-thaw protection are needed.
