Hind Block Fix is a ready to use, self curing and
non-shrink block fixing compound, blended carefully and formulated to a
prefect adhesive, based on Portland cement, graded aggregates and
polymers. By addition of water a high strength thixo-tropic mortar is
obtained which is used for laying of Fly Ash bricks, Aerated light
weight concrete, cement & hollow blocks and Cellular concrete
blocks. Plaster to a thickness of 12mm can also be achieved with Hind Block Fix to cover up the block work surface and it meets all Standards Nationally as well as Internationally. It conforms to ANSI A118.1 & ANSI A118.4 (1999) , EN-1348 & ASTM C 1660-09.
For preparation of a thin bed adhesive for fixing of AAC, ALC and cellular concrete blocks both for interior and exterior use.
- Easy to use, only water to be added & long working time makes work to be carried at a fast pace and is very economical.
- No curing is required after block fixing work is done.
- Possess the unique property of getting self cured.
- High Strength and perfect adhesion between two blocks.
- Flexible, shock and impact resistant.
- Good mechanical strength. (Bond strength, compressive & tensile strength)
- Thinner joints with high adhesion are achieved contributing to the load bearing capacity of the masonry.
All surfaces should be sound, clean and free from any contamination
like grease, oil, loose particles etc. and structurally sound. Uneven
and rough surface should be made smooth before to application of Hind Block Fix. It can be applied on damp surface also. All slabs must be plumb and true and should be within 1/4
inch (6mm) tin 10ft (3mm). If any Expansion joints are observed it
should not be covered with the mortar and treatment to be done as per
technical specification mentioned in the drawing.
Mix 20 Kg of Hind Block Fix with 5.5- 6.0 Litre of potable water. The water should be taken in a container and Hind Block Fix to be added to the water slowly and mixed with hand or a slow speed paddle mixer for 3-4 minutes to
obtain a lump free smooth thixo-tropic mix of trowel able consistency.
Water can be reduced or increased slightly to achieve desired
Application as a thin bed mortar for laying blocks:
The substrate over which the blocks are to be laid should properly
cleaned from all loose particles before placing the mortar. The mortar
is placed on the block work in thin layers of 2mm – 3mm with a trowel
and the next layer of blocks are placed over it. The joints between the
blocks are maintained as per the requirements and to be filled with the
mortar by using a trowel. Plumbing is done to maintain the verticality
of the wall.
Smoothing over the block work:
Application of a bonding layer of 1mm -2mm thick of Hind Block Fix is to be done using a trowel and pressing it downwards before placing the mixed mortar. Finally using Hind Block Fix Adhesive of 8mm-10mm thickness it is smoothened with a wooden/rubber float or sponge.
Cleaning: Cleaning of all tools used to be washed with clean water before it gets dried.

Coverage is dependent on the smoothness and evenness of the
substrate, block size used and thickness of the mortar used in laying
the block. A guide to the coverage is appended for reference purpose
