Product Description and Features

Product Description

weber.blokset plus is a high grade non-refractory mortar consisting of high performance polymers for bonding masonry units, like AAC blocks. It is a Weber proprietory formulationof belended polymers, hydration retainers, cement, mineral additives and graded fine sand to have excellent grip and adhesion strength between block to block and block to cementitious surface. weber bloksetplus is in compliance with C1660-09 ASTM standards( which is worlds only standard for then bed mortar for autoclaved aerated cement masonry.

Key Features

  • ASTM Complaint: It is specially formulated and tested to be in compliance wit ASTM C 1660 - 09 and gives the confidence to the consumer of a product based on research standards.
  • Fast construction and higher productivity: weber bloksetplus is a timely setting mortar which allows uninterrupted block mounting which is far lower in time than conventional and ordinary mortars. Combined with qualities of good workability, spread of material and no need of curing, weber bloset plus increases the speed of construction 24- 48 hours before next stage like plastering.
  • Water Savings: weber blokst plus is designed to eliminate the need for any external water curing which save critical resource like water.  
  • No wall hight constraint: Timely setting properties of weber bloksetplus and flatness acheived minimizes anyrestriction on the height of walls that can be built in a day.
  • Minimizes shrinkage and seepage:weber bloketpls is a thin bed, polymer rich formulation, which minimizes shrinkage and water ingress.
  • Improved workability: Due to polymeric and mineral additives it results into improved flow, water ritention and open time.
  • Less storage space: weber blokset plus is a ready o mix product there by eliminating need for bulk storage of sand and cement.
  • Cost effective: webr blokset plus is appliedin less thickness having superior coverage and reduction in wastage due to potlife and no water curing required.
  • High bonding(tensile spitting strength): Optimally polymerized weber blokset plus provides theadditional chemical bonding apart frm the improved mechanical sand-cement bonding due to hydration retainer compounds which gives solid robust wall with long lasting durability and this strength is achieved at very thin thickness of 2mm.
  • Construction accuracy: Due to measured application and thin bed, the wall construction is accurate.
  • Wthstand hammering and chiseling: weber bloksetplus bonds are able to withstand the hammering and chiseling required to be done for window, door frames and conduiting after 48 - 72 hours.
  • Versatility of application: weber blokset plus is a high bonding adhesive for AAC blocks, which when applied with notch trowel.
  • Environment friendly: Portion of weber bloksetplus is made of one of byproducts of industry helps in reducing carbon footprint at the same time no water required for curing helps in restoration of natural resources.


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

Preparation and Application

Direction For Use


  • No pre-wetting of blocks
  • 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 respective surface should be free from voids, holes and cracks

Mixing Ratio

  • Gradually add 2.5 parts of powder to 1 part of water (by volume) and mix for 5 - 10 mins to achieve smooth paste consistency.
  • Attempt to be made to break the lump durng mixing so that maximum dipersion of polymer tkes place in the mortar resulting into good bonding strength with the blocks.
  • After mixing allow the paste to stand for 2- 3 minutes for it 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 bloksetplus on the block, with the help of a trowel spread mortar uniformly on the unit.
  • Use appropriate tool for good transfer and firmly place the block with slight shear to ensure good transfer and bonding.
  • weber bloksetplus to be applied on the faces of the block andon column and beam, material to be applied on both surfaces as well as on block to ensure good bonding at the joints.
  • Use rubber hammer to have good contact between the blocks.
  • Go on placng blocks  with above methord and erect the wall.


For a 2mm bed thickness the coverage will be 3.5 - 4 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.
