Product Description

MagicBond Block Joining Mortar

MagicBond is a high strength adhesive for quick and firm laying of AAC blocks with thin joints (Applied in 2-3 mm layers). It is also referred to as Thin-bed Mortar or AAC Block Jointing Mortar.

MagicBond is a factory mixed mortar made up of cement, graded sand and blended with polymers to impart high strength and water retention.

98% of AAC Fly Ash Blocks worldwide are joined using thin bed mortar.

Features & Benefits
High Bond Strength

Special polymer imparts high adhesive strength(0.34 Mpa) increasing overall masonry strength and load bearing capacity.

No Shrinkage Cracks

Water is retained in mortar, thus prevents shrinkage cracks.


Quantity or MagicBond required for lying blocks is 3 times less than conventional mortar. This save money as well as time.

High Coverage

Due to low density & higher volume, a 40 kgs bag of MagicBond covers 170-180 sq.ft. with a thickness 3mm (for 4" thick AAC fly ash blocks)

No Curing required

Due to water retention polymers, curing is not essential after application


No jobsite blending of powder is required, only water is to be added.

High Thermal Insulation

Thin joints prevent heat transfer through walls.

Zero Wastage

It is easy to apply and avoids wastage of material.
