Superior Bond, Water Rentention and Board Life

Standard (TP-01) and Color (TP-05)


SPEC MIX® Tuckpoint mortar is a dry preblended mortar mix containing Portland cement, hydrated lime and dried masonry sand formulated for superior bond, water retention and board life.  The mix design incorporates the maximum amount of lime for optimal bond to the masonry unit to permit the pointed wall to expand and contract, while mitigating the occurrence of potential cracking and spalling that is common with inflexible, high strength mortars. SPEC MX Tuckpoint mortar is thoroughly pretested to ensure It meets ASTM C 270 and ASTM C 1714 requirements. SPEC MIX Tuckpoint mortar is available in standard or custom colors. In addition, custom mix designs are available for specific applications or properties, the standard Tuckpoint 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.

SPEC MIX Tuckpoint 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. Each SPEC MIX manufacturer certifies that SPEC MIX masonry products are designed to meet the project specifications and applicable ASTM and ACI standards.

SPEC MIX® Tuckpoint Mortar is available in 80 lb. (36.3 kg.) packages for easy hand loading or in 3,000 lb. (1,360.8 kg.) reusable bulk bags to be used with the various SPEC MIX® silo systems.
