  • Before applying the material, clean the surface from any types of oil, rust, detergents, dirt and other substances that prevent setting.
  • When laying aerated concrete blocks on a concrete surface, it should be slightly moistened.
  • Pour 6.5-8.5 liters of clean water into a clean container. Pour the Teknofay 500 powder (25 kg) into a container with water and use a low-speed mixer to knead the compound for at least 5 minutes until a homogeneous mass is obtained. Leave the resulting compound for 3 minutes, then re-mix it with a mixer for 2 minutes.


  • The prepared morter is distributed over the surface with a notched spatula. Within 5 minutes, you should lay out and fix the material on the surface. If 5 minutes have passed, it is necessary to scrape the morter from the surface and throw it away, then apply a new layer of the morter. For better fastening, the material to be laid should be pressed down a little.
  • The work should be at an air temperature of +5 to +35 °C. When laying tiles at a low (below +5 °C) or elevated (above +35 °C) temperature, it is necessary to cover freshly laid bricks or aerated concrete blocks with thermal insulation material.
  • It is recommended to perform a trial laying of the material to determine the required amount of morter, since the consumption may differ under different weather conditions.
  • After applying the morter, it is necessary to protect the surface from adverse weather conditions, such as direct sunlight, strong wind, high air temperature (more than +35 °C), rain and frost.
  • The tools and equipment used must be washed with warm water immediately after use. You should also wash your hands thoroughly.
