About AAC Thin Bed Mortar

Scentus AAC Block Adhesive is a versatile thin jointing material for laying AAC blocks, fly ash bricks, concrete blocks etc. The product is specially designed to provide higher bonding as a result of higher tensile adhesion strength. AAC Block Adhesive is pre-mixed, easy to apply high quality mortar comprising of cement, graded sand and admixtures. AAC Block Adhesive replaces conventional jointing mortar of 12-18 mm thickness with highly versatile 3-5 mm thickness. Scentus AAC Block Adhesive helps to speed up the build process and achieve the required insulation performance of AAC Blocks for the buildings. AAC Block Adhesive (Thin joint masonry) is a fast, clean, accurate system for construction using autoclaved aerated concrete blocks of close dimensional tolerance.

Features and Benefits

  • Thin jointing material with very high adhesion strength
  • Pre-mixed and ready-to-use. Only water is to be mixed at site
  • Eliminates lengthy and cumbersome processes of site mixing, thus transport and storage of all individual materials is avoided
  • Easy to mix and much faster application
  • Thin layer application results in structure being compact
  • No water curing is required after application
  • Minimizes the undulation of the surface
  • Being a thin layer, chances of water percolation is negligible
  • Being premixed, it saves considerable time and labour
  • Ready for subsequent application like plastering just after 24 hours of application
  • Eco-friendly product
  • Raw materials are processed, reducing the chances of efflorescence

Areas of Application

  • Laying and jointing of fly ash bricks, cement blocks, hollow blocks, AAC blocks etc.
  • Jointing of pre-stressed concrete slabs, panels.
  • Parapet walls
  • Jointing of cement window and door frames.
  • Garden and boundary walls.

Surface Preparation

  • The base surface should be properly cured prior to application of AAC Block Adhesive.
  • The surface must be cleaned thoroughly, with no loose particles or dust.
  • The surface must be structurally sound, clean and free from dirt, oil, grease, efflorescence and any other contaminant which could impair the natural bond.
  • Surface defects such as cracks, holes or voids should be repaired prior to application.


  • It is very important that AAC Block Adhesive is mixed with water properly and thoroughly before use.
  • It is advisable to use a mechanical stirrer for uniform and thorough mixing to save time, labour and for maximum workability.
  • Take a clean vessel/bucket, add water to it and put required quantity of AAC Block Adhesive in it.
  • Mixing Ratio – Clean potable water (approximately 25%-30%) of the weight of the powder is required to be mixed depending upon the thickness of the product to be applied. Water is to be incrementally added in stages to get a smooth, uniform and workable mix. Allow ample of time for initial mixing.
  • Ensure that no powder is left unmixed at the bottom of the vessel. The AAC Block Adhesive is now ready for application.

Application Procedure

  • Layout the wall in which AAC Block Adhesive is to be used and mark openings like door, windows, any architectural appurtenances etc.
  • Put a thin layer of AAC Block Adhesive in the thickness of 3 to 5mm on the clean and leveled surface using proper trowel on which the block work is to be carried out.
  • Place the block on the laid AAC Block Adhesive in proper line and level.
  • After placing the first block apply the AAC Block Adhesive of same thickness on both the sides of the block continuously keeping a check on the line and level.
  • Clean the excess material, if any immediately. Continue the procedure for the entire block work.
