Abstract

A sealer composition for a cementitious substrate, a cementitious structure sealed with the sealer composition, and a method of sealing a steel reinforced cementitious structure with the sealer composition. The sealer composition includes a substantially non-aqueous blend of a first silane, a second silane having a higher molecular weight than the first silane, and a corrosion inhibitor. The corrosion inhibitor is soluble in silane, soluble in solvent-diluted silane, and at least partially soluble in water. The cementitious structure includes a cementitious substrate and the sealer applied to the surface of the substrate and at least partially penetrating into the substrate. The method of sealing a steel reinforced cementitious structure from intrusion of corrosion-causing agents includes applying the sealer to the surface of a steel reinforced cementitious substrate and permitting the sealer composition to penetrate into the substrate to seal the substrate.
