Block Jointer Mortar

Build Square Block Jointer Mortar is a specialized jointing compound—high quality of cement, natural sand, and chemical additives—specifically formulated for use with AAC blocks.

A block jointer is a hand tool commonly used in masonry work to finish and shape the mortar joints between AAC blocks. After the mortar has been applied and partially set , the block jointer is drawn along the joint to create a smooth, uniform finish. The block jointer is applied in a thin layer of just 3 to 4 mm; consequently, it leaves no gaps within the Aac block assembly. This not only enhances the aesthetic appeal of the wall but also improves its durability by protecting the joints from moisture ingress. Furthermore, it ensures strong bonding, rapid application, and minimal material wastage.
