• 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) mixture 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 mixture.
• Apply the mixture to the surface for 2.5 minutes. To repair the surface, the mixture 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 more than 400 mm, you can add 30% of pure gravel with a size of 18-25 mm to the mixture. The filler must be added to the pre-prepared solution and mixed until a homogeneous mixture is obtained.

Notes:

• When used at a low temperature, the lifetime of the mixture 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.
