Cool Mortar

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

Wet the entire surface with clean water before the Cool Mortar application to neutralize the substrate suction. The surface should look damp at the time of the Cool Mortar applicatio.

Add to the mixing container 6 - 7.4 liters of water for each 20kg 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 until achieving a uniform, lump-free consistency.

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

Manual mixing is allowed for small batch quantities. Mix the whole bag with water for approximately 1-2 min or until achieving a homogeneous mix.

Saturate the block surface with water before applying Cool Mortar. Remove any excess water.

Spread Cool Mortar on the surface and joints where the blocks will be mounted using a trowel.

Fill the joints in a similar way as per the conventional sand/ cement mortar application.

After stiffening, give the Cool Mortar surface a final smoothening to remove protrusions and to eliminate undulations.

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

Clean all tools should immediately after finishing with water. Clean the hardened material mechanically.
