POLAR® Block Block Jointing Mortar is a high-strength adhesive for quick and firm laying of AAC blocks with thin joints. Made of cement, graded sand, and blended with polymers, it provides high strength and water retention properties even when in thickness of 2-3 mm layer.
With improved compressive and tensile strength, it offers better value for money compared to other products. POLAR® meets ASTM-C1660-09 quality standards.
Applications
- Laying & Joining of AAC Blocks.
- It could be used to lay fly ash bricks and concrete blocks.
- Used as an option to the conventional cement and sand mix mortar.
- Joining of Concrete Windows and Door Frames etc.
Storage
- Product should be stored in a dry place strictly away from moisture
Advantages
- Ready to use, only water to be added.
- Thinner jointing material with very high tensile adhesion 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 conventional mortar
- Self-curing.
- Eliminates the need for storage due to ready to mix feature.
- Strengthens the wall and make them long-lasting.
- Provides regulation of heat through walls.
- Prevents seepage and water percolation during and after application.
- It helps achieve better leveling and avoid shrinkage cracks
Shelf Life
- 24 months in unopened packaging in a strictly dry and cool storage place
How to use
- POLAR® Block Joining Mortar must be mechanically mixed using a forced action mixer or in a clean container 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 remix 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 POLAR® Block Joining Mortar 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 Block Jointing 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. Continue the procedure for the entire masonry work. Do not disturb the blocks /bricks setting for first 24 hour
Restriction of usage
- It is ready to use block Block Jointing Mortar so do not add sand and cement further and always add recommended percentage of water
- To avoid formation of lump, always add powder to water and not water to powder
Handling precautions
- Provide adequate ventilation
