ABSTRACT:
A patching composition in the form of a putty composition for application to concrete surfaces. The composition comprises a substantial portion of a conventional cement, such as a Portland cement, and a silica sand selected to have the right consistency and density along with calcium oxide. The composition is then mixed in water and applied to voids or holes in a concrete wall. The composition, when applied as a single coating and fully cured, results in an appearance similar to that of the concrete and provides strength characteristics substantially equivalent to that of the original concrete.
