  • Elastic
  • For horizontal and vertical surfaces
  • It has a high adhesion
  • High thixotropic properties
  • It is easy to prepare and apply
  • Resistant to water, moisture and freezing
  • Long life time of the mixture
  • Does not slide in an upright position

Instructions for use:

Surface quality: the application surface must be cleaned of materials that prevent adhesion, such as dust, oil, resin and detergents. Weak parts should be dismantled, and the damaged surface should be repaired using appropriate TEKNOREP materials. There should be no oil, dirt and rust on the surface.

Surface preparation: if the application will be carried out on marble, ceramics or a palette, the surface should be roughened. The concrete floor should be wet, but there should be no puddles on it.

Mixing: Pour 6.0-7.0 liters of water into a clean container, which does not contain all types of materials that prevent adhesion. Teknofay Flex is added to a container with water, it is mixed with a low-speed mixer until a homogeneous mixture without lumps is obtained. The mixing time should be at least 5 minutes. Leave the solution obtained at the end of the process alone for 5-10 minutes, then mix it again for 2 minutes until it becomes homogeneous.

Recommendations for use:

The product may cause irritation if it gets on the skin. Work clothes, protective gloves, masks and glasses should be used. A protective cream can be applied to the hand before starting work. If the solution gets into your eyes, immediately rinse your eyes with warm water and consult a doctor.
In environmental conditions that will remain below ( ) 5°C, it must be protected, covered with nylon or protect the product from frost by putting thermal insulation boards.
It should be protected at temperatures above ( ) 35°C, should be covered with nylon or the product should be protected from sudden water loss by enclosing thermal insulation boards.
After 24 hours after applying Teknofay Flex, the sealing of the seams should begin.
Do not add foreign substances.
After application, it is necessary to protect against adverse weather conditions, such as direct sunlight, strong wind, high air temperature (more than 35 ° C), rain and frost.
