aeroBOND Block Joining mortar is a semi premix high quality mortar for jointing and bonding of AAC blocks, concrete blocks, hollow blocks, clay bricks and fly ash bricks. aeroBOND block jointing mortar semi premix consists of cement, graded sand and specialised polymers which combine to give superior strength, water retention and stability. It replaces the conventional method and material of jointing mortar which requires a 12-18 mm thickness with a revolutionary 3-5 mm joint thickness. aeroBOND block jointing mortar only requires addition of water before application to prepare the product for use, reducing the hassle of measuring and maintaining various individual elements to create a conventional mortar.



Water Saver

Water curing is not required after the application of aeroBOND block jointing mortar as it contains self curing properties.


Less Quantity

Since the quantity required is 75% less than conventional mortar, the storage requirements are comparatively minimal, saving site storage space and handling.


Minimum Process Time

After aeroBOND block jointing mortar is applied, the wall will be ready for plaster within a short time of just 24 hours.



Since the quantity required is 75% less than conventional mortar, the storage requirements are comparatively minimal, saving site storage space and handling.


Time Saving

No site mixing required for various raw materials and overall less material required in the application process, which leads to less handling and quicker application, eliminating the lengthy process of wall construction.


Prevention of Efflorescence

Since the raw materials of aeroBOND block jointing mortar are well processed and treated in a standardised condition and method, the chances of efflorescence are minimum.


Thin Joints

Reducing the overall jointing material by around 75%, aeroBOND block jointing mortar joints are also known for their high adhesive strength, enhancing the quality of masonry and minimizing shrinkage. Thin joints will also lead to accuracy in workmanship and neatness in the masonry work.



aeroBOND block jointing mortar bags are semi-premix solutions which only require the addition of water to prepare for application, reducing the hassle of mixing various raw materials and further saving a lot of time and manpower.


No Raking

Raking of the joints or “U” grooving of the joints are not required before plastering, saving time and manpower.


Easy Application

Easy to mix, blend and apply due to the smooth texture of the mortar, the semipremix ensures higher flow-ability and water retention properties.
