Application Information
Instructions for use

Add to the mixing container 12.5-15 litres of clean water for 50 Kg bag of Vetoblock Mortar AAC. 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.

Neutralize the suction of the block surface with water before applying mortar. Any excess water should be removed.
Ensure that the first layer of blocks is fixed proper with perfect alignment.
The Vetoblock Mortar AAC is spread with trowel on the surface and joints where the blocks are to be mounted. 
Vetoblock Mortar AAC should be applied in a thin layer to enable the continuity of thermo-insulation of the blocks. Leave a space of about 2 cm between the top of block wall and the bottom of slab or beam in order to avoid formation of cracks along the wall. This cavity should be filled with compressible material.
If the blocks are laid directly on a floor with possible humidity rising, it is recommended to apply a proper damp course system first.

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

Surface Preparation

The AAC block/panel surface should be sound, clean, free from loose material, grease, laitance, dirt, curing compound, etc.
Prior to Vetoblock Mortar AAC application, wet the entire surfaces with clean potable water and surface should look damp at the time of VetoBlock Mortar application.

  • After application, avoid rapid evaporation of water that may cause the small superficial fissures appearance due to plastic shrinkage.
  • Damp the surface for the initial 48 hours by spraying water and covering it with impermeable sheets. Subsequent plastering may commence after 1 day during summer, and preferably after 2-3 days during winter season.
  • The product should not be exposed to moving water during application.
  • Do not apply the product at temperature less than +5ºC. During summer season the working area must be covered to prevent ill-effects from direct sun.
