STANDARD SET BLOCK FIX
High Bond Strength Thin-Bed Block Jointing Mortar
ASTM C 1660 – Classified Product
Product Description
STANDARD SET BLOCK FIX is a thin-bed, high bond strength, pre-mixed masonry
mortar comprising Portland cement, specially graded sand and polymer
admixtures. It is formulated to provide excellent adhesion with air-entraining
properties and replaces conventional 12–18 mm sand–cement mortar with a
versatile ~3 mm joint thickness, enabling faster, economical wall construction.
Special Features
- Higher bonding with enhanced air entrainment for superior block adhesion.
- Thin 3 mm joints reduce material consumption and construction cost.
- Non-shrink formulation helps prevent cracks in block joints.
- Fast setting system “glues” blocks together quickly.
- Ready-mixed, consistent quality product for new construction and renovation.
- Eco-friendly solution with no post-fixing curing required.
Applications
- Fixing of AAC and CLC blocks in internal and external walls.
- Jointing of hollow blocks and solid concrete blocks.
- Laying normal burnt clay bricks and fly ash bricks.
- Block-to-block and surface-to-block fixing applications.
Suitable Substrates
- Concrete blocks and cement mortar blocks/bricks.
- Cement hollow blocks.
- AAC and CLC blocks.
- Fly ash bricks.
