SPEC MIX® Set Delayed Masonry Mortar is a dry preblended set-delayed mortar mix using either a portland cement and hydrated lime formulation, a masonry cement formulation or mortar cement formulation, depending on specific building codes. 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, ASTM C 1714, ASTM C 1384, and CSA A179 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 Mortars are designed to be compatible with the characteristics of the specified masonry unit. There is a version acceptable for all types of masonry construction, above or below grade.

Set Delayed Masonry Mortar is produced under strict manufacturing standards, and complete quality control measures are implemented with each batch. A digital printout displaying the proper proportions per batch may be kept as a permanent record.
