UBF (Universal Block Fixer) is a block fixing ready mix. It’s factory-made premixed mortar blended with carefully selected raw material such as graded sand, mineral binders and ordinary portland cement (OPC) in combination with selected polymeric additives which is providing mechanical bond and adhesion between the blocks and block to a surface. It is specially formulated and easily applied, giving a higher bonding with significantly higher air-entraining properties. UBF is a masonry mortar for use in laying bricks, block, AAC, CLC or stone. It replaces conventional jointing mortar of 12-18 mm thickness with highly versatile 3-5 mm thickness.
