Jointing Mortar UltraTech Jointing Mortar is a versatile thin jointing material for laying AAC blocks, fly ash bricks, concrete blocks etc. This mortar is specially designed to provide stronger, much more durable bonding between the blocks and superior adhesive strength. It replaces conventional cement and sand mix mortar. Ultratech Jointing Mortar is made from a unique combination of cement, graded sand and selective additives. The unique chemical combination enables this mortar to more compact, thinner and more versatile. At only 3 mm thick it is far thinner than the conventional mortar which is between 12 - 18 mm. It is pre - mixed so it is easy to use and also ensures the compaction of interlocking bricks making the bonds tougher and more durable.
Special Features & Benefits:
-
Thinner jointing material with very high adhesive strength. Improves overall masonry strength and load bearing capacity.
-
Pre-mixed and ready to use. Only water is to be added at site.
-
Eliminates lengthy process of site mixing, transport and storage of all individual materials.
-
No water curing is required after application.
-
Easy to mix. Much faster to apply due to its superior flow ability and water retention properties.
-
Thinner layer of application for lesser shrinkage and seamless structure.
-
Economical Quantity of mortar is far less than conventional mortar.
-
Seepage / water percolation through joints is negligible due to integrity of mortar joints with masonry units.
-
Ready for subsequent application like plastering just after 24 hours of application
-
Raking of joints is not required before plastering.
-
Raw materials are processed, reducing the chances of efflorescence
-
Ultratech Jointing Mortar is made from Eco - friendly materials.
Surface Preperation:
-
The surface is masonry units should be slightly wet prior to application of Jointing Mortar.
-
The masonry units should be clean, with no loose particles or dust for better bonding.
-
The surface must be structurally sound. Efflorescence & any other contaminant which could impair the natural bond should be removed.
-
Surface detects such as cracks, holes or voids should be repaired prior to application
Mixing:
-
It is very important that Ultratech Jointing Mortar is mixed with water thoroughly before use. It is advisable to use a mechanical stirrer for uniform mixing to save time, labour and for maximum workability effectiveness.
-
Use a clean vessel / bucket which does not have any hole or cut and add some water in the empty vessel to ensure no powder gets stuck on the bottom of the vessel and put required quantity of UltraTech Jointing Mortar.
-
Mixing Ratio Depending on the thickness of the product to be applied, add approximately mix 25% - 30% of the clean potable water and 70% of powder and mix. Water is added in stages to get a smooth, uniform, workable mix. Allow ample of time for initial mixing.
-
Ensure that no powder is left unmixed at the bottom of the vessel.
-
The jointing mortar is now ready for application.
Areas of Applications:
-
Laying and jointing of masonry units like fly ash bricks, concrete blocks, hollow blocks, AAC blocks, etc
-
Jointing of pre-stressed concrete slabs, panels.
-
Jointing of Cement Concrete floor tiles
-
Jointing of concrete window and door frames.
Method of Application:
-
Layout the wall where Jointing Mortar is to be used and mark openings like door, windows or any architectural appurtenances.
-
Apply a thin uniform layer of Jointing Mortar 3 to 4 mm thick on the clean & leveled surface of masonry units using proper trowel.
-
Place the next course of masonry units on the evently laid jointing mortar bed in proper line & level. Each masonry unit shall be properly bedded and set in position by gently pressing with the handle of a trowel.
-
After placing the first unit, apply the jointing mortar of same thickness on both the sides of the unit, keeping continuous check for the line & level.
-
Inside face of the masonry unit shall be buttered with mortar before the next unit is laid and pressed against it especially in case of bricks.
-
Clean the excess material, if any immediately. Continue the procedure for the entire masonry work.
Coverage:
-
Under normal condition, the coverage of jointing Mortar is approx. 90 - 100 sq. Ft with average thickness of 3 mm for a Bag of 25 kg for block size 600 x 200 x 150mm. The coverage area however will depend upon the quality & evenness of the substrate, thickness of joints and size of masonry units.
-
For best result proper tools for mixing and application is desirable. It will result in higher coverage and savings in time and manpower.
Precautions During Usage:
-
Though Jointing Mortar contains no toxic materials, still care should be taken to avoid dust inhalation while mixing and handling. In case of contact with eyes or face, wash with plenty of clean water.
-
Keep it in a dry place and out of reach of children.
-
Persons who are allergic to cement should take proper precausions before use.
