Sto Corp. has introduced Trowel Grade Repair Mortar with integral corrosion inhibitor (CR701CI). The product, an enhanced reformulation of CR701, is designed to provide an integral corrosion inhibitor that has been a requirement by many specifying engineers. Sto Trowel-Grade Mortar is a polymer-modified, cementbased mortar for structurally repairing or overlaying deteriorated concrete. Used on horizontal or vertical surfaces for repairs from 1⁄4 to 2 inches or extended with aggregate for deeper horizontal applications, its formula provides increased strength gain and improved performance for repair applications. Sto has also released a new Extended Full Depth Repair Mortar. The product is an enhanced formulation of Sto’s CR311, offering the additional benefit of a factoryblended extension aggregate to allow for increased product quality and job performance when extension is necessary. Sto Extended Full Depth Repair is a cementbased mortar for structurally repairing or overlaying deteriorated concrete. It is typically used on horizontal surfaces for repairs from 11⁄2 to 6 inches and provides increased strength gain and improved performance for repair applications. It also takes advantage of the added quality and convenience of a factory controlled addition of prewashed, kiln dried, and rounded pea gravel.
