How To Apply:
Block Jointing Mortar can be laying and joining of masonry units like Fly Ash block, ACC block, hollow, concrete blocks etc.
Before application surface should be clean and free from dust, grease, oil and any other foreign material.
Pre-wet the surface of the block before applying mortar. Allow excess water to drain off.
Apply the material on the block evenly with trowel. For best results it is advisable to use notch trowel of 3 to 4 mm to have better contact and bonding.
Application should be done by the angle between 35 to 45 degrees, using the right amount of pressure.
Use fibre hammer to remove any air gaps in between blocks for proper jointing and alignment.
Fill the gap between two blocks with the help of trowel and remove excess material.
Mortar should be spread on all sides of the block in such way to maintain the bond thickness 2-3 mm.
The coverage area however will depend upon the quality and evenness of the substrate, thickness of joints.
