Product Description and Features

Product Description

weber.blokset is a non-refractory mortar consisting of high performance polymers for bonding masonry units, like AAC blocks. It is made from  polymeric additives which helps in providing a mechanical bond and adhesion between block to block and block to surface. weber blokset is i complaince with ASTM C 1660 - 09 standards ( which is worlds only standard for thin bed mortar for aerated autoclaved concrete masonry.

Key Features

  • Self curing: weber blokset is designed to eliminate the need for external water curing which saves critcal resource like water.
  • Minimized shrinkage and seepage: weber blokset is a thin bed, polymer rich formulation, which minimizes shrinkage as well as water ingress.
  • Improved workability: Due to polymeric and mineral additives it results into improved flow, water retention and open time.
  • Less storage space: weber blokset is a ready to mix product there by eliminating need for bulk storage of sand and cement.
  • Cost effective: weber blokset is applied in less thickness having superior coverage and reduction in wastage due to pot life and no water curing required.
  • High bonding (tensile splitting strength): Optimally polymerized weber blokset provides the additional chemical bonding apart from the improved mecanical sand - cement bonding due to hydration retainer compounds which gives solid robust walls with long lasting durability and this strength is achieved at very thin thickness above 3mm.
  • Construction accuracy: Due to measure application and thin bed, the wall construction is accurate.
  • Withstand hammering and chiseling: The weber blokset bonds are able to withstand the hammering and chiseling required to be done for window door frames and conduiting as per standard masory practice.
  • Environent friendly: Portion of weber blokset is made of by products of industry helps in reducing carbon foot print a the same time no water required for curing helps in restoration of natural resources.
  • ASTM Compliant: weber blokset conforms with ASTM C 1660 - 09
  • Wall construction speed: As per standard masonry practices (generally from 2 days).


It is recommended for fixing AAC, CLC, hollow, concrete blocks and bricks.

Preparation and Application

Direction For Use


  • Pre-wet the blocks and esure it is touch dry before thin bed masony mortar is applied.
  • The surface for mounting must be throughly cleaned of all laitance, loose materials, oil greases etc.
  • Ensure that the surface is flat, structually sound and free from any other contamination which would reduce the bond strength.
  • The surface should be free from voids, holes and cracks.

Mixing Ratio

  • Gradually add 3 parts of powder to 1 part of water (by volume) and mix for 5 - 10 mins to acheive a smooth paste consistency.
  • Attempt to be made to break the lump during mixing so that maximum disprsion of polymers takes place in the mortar resulting into good bonding strength with the blocks.
  • After mixing allow the paste to stand for 2- 3 mins to mature and again mix it for paste consistency.
  • Do not attempt to extend the pot life by adding more water to the mixed adhesive.

Application Methodology

  • Put well mixed weber blokset on the block, with he help ofa trowel spread mortar uniformly on the unit.
  • Use the notch trowel for good transfer and firmly place the block with slight shear to ensure good ransfer and bonding.
  • weber blokset to be applied on the faces of the block and on column and beam, material to be applied on both ie surfaces as well as on block to ensure good bonding at the joints.
  • Use rbber hammer to have good contact between the blocks.
  • Go on placing the blocks with the above methord and erect the wall.


For a 3mm bed thickness the coverage will be 5-5.5 kg/sqm
Note:The coverage will vary depending on surface undulations.

Shelf Life

1 year from the date of manufacturing,  for unopened bags, stored in dry condition.
