Application Procedure

The surface area where BuildWell Block Jointing Mortar needs to be applied should be sound, thoroughly clean and free from dust, grease, oil and any loose material. The masonry surface should be pre-wetted before applying BuildWell Block Jointing Mortar. Line out on the concrete slab should be done by using conventional cement mortar to get the desired line level.

Take the required quantity of water in a clean bucket, add BuildWell Block Jointing Mortar as recommended. Stir continuously for 5 -10 minutes by using an electric mixer or by hand to obtain a homogeneous lump free mix. Allow the resultant wet mortar to stand for about 5 minutes for the additives to dissolve. Re-mix again for about 2 minutes. The mixture is now ready. Use the mix within 60 minutes. For best results it is advisable to use notch trowel of 3 to 4 mm to have better contact and bonding.

Depending upon the substrate and climate add approx. 9 to 11 liters of water for 40 kg bag. For concrete blocks, wet mortar should have less water to form 2 to 3 mm bed of BuildWell Block Jointing Mortar.

Laying and joining of masonary units like AAC Blocks, Hollow Blocks, Fly ash Bricks and concrete Blocks, etc. Joining of concrete window and door frames, etc..

BuildWell Block Jointing Mortar contains only eco-friendly fillers and additives. However being sand and cement based it is alkaline and hence it is advisable to avoid direct eye and skin contact with this. In case of eye contact, wash with clean water for at least 15 minutes and seek for medical help if needed and recommend to keep it out of reach of children.
