Mortar Mix, Rapid Set, 1 hr Cure Time, 25 lb

Mortar is applied between concrete blocks, bricks, and stone to act as the glue when building walls, chimneys, or fire pits. It is lower strength than concrete and has a more malleable, creamy consistency. Its formulated to retain water and air and provides a breakable buffer between blocks and bricks when a wall shifts over time. Mortar can be reapplied to "repoint" a wall where mortar has cracked or crumbled away.
