Blended thoroughly with dried masonry sand and proprietary set delaying admixtures formulated for longer board life, superior bond, and water retention, Set Delayed Mortar slows the initial set time in hot weather conditions. This product meets ASTM C 270 and ASTM C 1384 requirements and is suited for the installation of CMU, brick and stone unit masonry. In addition to custom mix designs that are available for specific applications or properties, the standard Set Delayed Masonry Mortar is designed to be compatible with the characteristics of the specified masonry unit. It is acceptable for all types of masonry construction with submittals available upon request. It may be used above or below grade when manufactured to the appropriate specification.
