Masonry Grout Filler

Masonry Grout Filler is a fine grout (as defined by the American Concrete Institute (ACI) that’s composed of Portland cement, natural sand, selected fine aggregates, and special additives. The product contains admixtures (following ASTM C 476, C207, C260) that allow it to meet the fine grout category (which makes it an ideal grout for masonry blocks, masonry units, and cores, as well as a filler behind marble slabs). Masonry Grout Filler is supplied as a dry powder in pre-weighed bags that are ready to use on-site (this only requires adding clean water to produce a pourable grout).
