DESCRIPTION
Ready to use grey cement based non-shrink, self- cur- ing mortar for fixing AAC blocks, Concrete blocks, fly ash bricks etc.
USES
Fixing and Jointing masonry units like AAC blocks, Con- crete blocks, fly ash bricks etc.
CHARACTERISTICS / ADVANTAGES
- Ready to use, only water to be added.
- Thinner jointing material with very high tensile adhe- sion strength improving the overall masonry strength.
- Better bond than conventional cement based mortar
- Faster to apply due to good spreadable properties.
- Excellent high strength & water retention properties
- Economical as quantity of mortar is less than conven- tional mortar
- Self-curing.

SUBSTRATE QUALITY / PRE-TREATMENT The substrate must be structurally sound, laitance
free, clean and free from dirt, oil, grease, other con-
taminants and loose or friable particles. Pre-wetting of substrate is essential with maximum saturation of wa- ter but saturated surface dry (S.S.D.) condition.
MIXING
Water: Powder = 0.22 to 0.24 by weight (8.8 L to 9.6 L water per 40 kg bag). Mixing Time : 3 minutes minim- um
APPLICATION
Shoolin Block Bond Adhesive must be mechanically mixed using a forced action mixer or in a clean con- tainer using a drill and mixing paddle (< 500 rpm). A normal concrete mixer is not suitable. Mix thoroughly with clean water for a minimum of 3 minutes. Leave material to stand in container until the majority of bubbles have dispersed (minimum 5 minutes).Then re- mix the material for 15 seconds – the product is now ready for use.
If the substrate is very porous, if the temperature is high and/or the relative humidity low, it is advisable to dampen the surface. Do not leave any standing water. Apply a thin uniform Layer of Shoolin Block Bond Adhesive 2 to 3 mm thick on the clean & levelled surface of masonry units using proper trowel
Place the next course of masonry units on evenly joint- ing mortar bed in proper line & level. Each masonry unit shall be properly bedded and set in position by gently pressing with handle of trowel.
Inside unit of the masonry unit shall be applied with mortar before the next unit is laid & pressed against it especially in case of bricks.
Clean the excess material, if any immediately. Contin- ue the procedure for the entire masonry work.
Do not disturb the blocks /bricks setting for first 24 hours.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
LIMITATIONS
Cementitious substrates must be at least 28 days old. Do not exceed the recommended water dosage. Apply only to sound, prepared substrates. Do not exceed the maximum layer thickness.
Protect freshly applied material from freezing and rain etc.
