  • Before applying the material, the surface should be cleaned of any types of oil, rust, detergents, dirt and other substances that prevent setting.
  • If necessary, replace the old damaged fittings with a new one.
  • When using additional fittings, make sure that it is covered with a material with a thickness of at least 2 cm.
  • Apply Teknogrout XXL at a temperature from + 2 °C to + 35 ° C.
  • Do not apply the material if the surface is covered with ice.
  • Before applying the material, the surface should be moistened.
  • To prepare the working solution, pour 3.0 liters of clean water into a clean container.  Pour the dry Teknogrout XXL (25 kg) compound into a container with water and use a low-speed mixer to knead the composition for 3 minutes until a homogeneous mass is obtained. Do not add water to the already mixed compound.
  • Apply the compound to the surface for 2.5 minutes. To repair the surface, the compound must be poured on one side in order to prevent the formation of cavities.
  • The thickness of the layer should be from 10 mm to 150 mm. 
  • When applying a layer of more than 400 mm, 30% of pure gravel (18-25 mm) can be added to the compund. The filler must be added to the pre-prepared solution and mixed until a homogeneous compound is obtained.


  • When used at a low temperature, the lifetime of the compound increases, at an elevated temperature it decreases.
  • When used in conditions of low temperature, it is necessary to use warm water, at elevated temperatures – cold water.
  • Do not use the material when the temperature drops to + 1 °C or lower within 24 hours after application.
  • The freshly laid solution must be protected from adverse weather conditions, such as direct sunlight, high temperatures < + 35 °C, precipitation and frost.
  • Work should be carried out in compliance with safety and hygiene standards, using a mask and glasses.
  • The tools and equipment used must be washed immediately after use.
