Water-repellant treatment for concrete, masonry and stone.


Dura.®sil S is a single-component, clear, penetrating, breathable silane-siloxane water repellent for use on exterior above-grade concrete, brick masonry and some natural stone to provide a hydrophobic surface to the pore structure.


Dura.®sil S, as a clear colourless coating, offers excellent water repellent properties to the surface/substrate, which enhances self-cleaning properties. Ideally suited for the exterior of most buildings including brickwork, cementitious finishes, natural stone and precast elements. Ideally used on reinforced concrete.
