Product Description

Block Jointing Mortar-7708 consists of cement, graded sand and specialized polymers which combine to give superior strength, water retention and stability.


  • Increasing overall masonry strength & load-bearing capacity
  • Providing high compressive & flexural strength
  • Superior adhesive strength
  • Higher durability
  • Strong bond between the blocks

Technical Analysis:

Pull-off strength
Dry adhesion -> 0.30 mpa

Compression & flexural strength (after 28 days)
Compressive strength - cs iv-- >6 mpa
Flexural strength -> 1.5 mpa

Water properties
Water absorption (after 28 days) - ≤ max 0.20 kg/meter2min0.5
Water retentivity -> 95 %

How To Apply:

  • Block Jointing Mortar-7708 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.
