Application Information
Instructions for use


Add to the mixing container 5.8 to 6.6 litres of water for each 20 Kg bag of Cool Mortar. Add the powder to the water and mix with a mechanical plaster mixer or low speed electric drill fitted with a suitable paddle for 3-4 minutes, until a uniform, lump-free consistency is achieved. 

Leave the mixed material to stand for 10 min and briefly remix without addition of water.

Manual mixing is allowed for small batch quantities by mixing for approx. 1-2 min, or when homogenous mix is achieved. 


Saturate the block surface with water before applying mortar. Any excess water should be removed.

Cool Mortar is spread with trowel on the surface and joints where the blocks are to be mounted.

Fill joint in similar way as conventional sand/cement mortar.

After stiffening, Cool Mortar should be given a final smoothing to remove protrusions and eliminates undulations.


Cool Mortar is a cementitious product and accordingly should be cured to recommended ACI and international curing practices. 


All tools should be cleaned immediately after finishing by water. Hardened materials can be cleaned mechanically.

Surface Preparation

The substrate should be sound, clean, free from loose material, grease, laitance, dirt, curing compound, etc. 

Prior to Cool Mortar application, wet the entire surfaces with clean potable water and surface  should look damp at the time of Cool Mortar application.
