Continental Block Joint Mortar
Thin-Bed Jointing Mortar for AAC BlocksKI'S Continental Block Joint Mortar is a factory-formulated thin-bed joinery mortar designed for bonding AAC blocks, concrete blocks, CLC blocks, and fly-ash bricks. Made with cement, specialized sands, and water-retaining polymers, it replaces traditional 15mm sand-cement joints with high-strength 3mm joints.

Areas of Application
Usage Guide & Method of Application
AAC blocks must be clean and free of dust. Wipe block edges with a damp sponge prior to laying to ensure proper adhesion.
Mix a 20 kg bag with 4.5 to 5.0 litres of clean water. Stir vigorously until a uniform paste is formed. Let sit for 3 minutes to activate polymers.
Apply mortar on the horizontal and vertical joints of blocks using a trowel. Lay block and tap into position with a rubber mallet. Check alignment.
Coverage
Approx. 90–100 sq.ft per 20 kg bag for 3 mm joint thickness (blocks sized 600x200x150 mm).
Precautions & Safety
- Do not lay dry blocks without wiping with a damp sponge.
- Do not add fresh powder to dynamic thick paste.
- Allow blockwork to cure for 24 hours before plastering.
