Product Description :

UST Confra block joining mortar is a high strength thin adhesive for quick and firm laying of AAC Blocks, fly ash bricks, concrete blocks, etc with thin joints. It’s a factory-mixed mortar made up of cement, graded stones, blended with polymers to deliver high strength and water retention properties even when in thickness of 2 -3 mm. With improved compressive and tensile strength, it offers better value for money compared to other products.


Increasing overall masonry strength & load-bearing capacity

Providing high compressive & flexural strength

Superior adhesive strength

Higher durability

Strong bond between the blocks

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.
