AF - Block Jointing Mortar
High-Strength Thin Bed Premix Mortar for AAC, Concrete & Hollow Blocks
Block Jointing Mortar is a pre-mix, pre-packed cementitious adhesive for joining AAC blocks. Cost-effective and easy to use with no water curing required at site. Polymer based non-shrinkable, self-curing mortar material with premix of grey cement, graded sand and polymer for superior binding.
KEY ARCHITECTURAL HIGHLIGHTS
[1]Self-curing formulation — eliminates site water curing of blockwork joints
[2]High pull-off tensile adhesion (> 0.35 MPa) prevents block joint delamination
[3]High coverage: 110–120 sq.ft per 40kg bag for standard 650×250×150mm blocks
[4]Reduces mortar joint thickness from 15mm (traditional) down to 3mm
