Substrate Preparation
Surface should be sound, clean, and free from oil, grease, dust deposits and other contaminants that may affect adhesion
Mixing
Add 3 - 3.5 Liters of clean water to AAC Block Markhor Mortar (20kg) and mix thoroughly using mechanical mixer for 1 - 3 minutes until a uniform paste is achieved and ensure that the mix is free from lumps.
Application
Before placing the mortar, ensure that the block work surface cleaned properly. Place the mixed on the block in thin layers of 2 to 3 mm using trowel and place the next layer of blocks on the mortar. Keep joints between the blocks as required and fill the joints with the mixed block mortar. Check the plumb of
the wall while laying the blocks to keep the walls perfectly vertical to the plumb
Packaging
AAC Block Markhor Mortar is packed in 20 kg Paper bag.
