The quality of the base / preliminary preparation

The application surface must be dry and free from any kind of dust, dirt, weak and loose particles, remains of cement mortar, oil and grease. If there are weak concrete parts, they should be removed, after which the surface should be repaired with a high-strength repair solution.

The concrete base must be clean, strong and have sufficient compressive strength (minimum 25 N/mm2) and tensile strength at least 1.5 N/mm2.


Before laying the Teknomer tape, it must be cut with scissors or a utility knife according to the length of the compensation seam and wiped with a small amount of solvent.

If necessary, put the tape on top of each other, the length of the overlap should be 10 cm. The tapes are connected to each other with the help of hot air. If desired, a polyethylene wick larger than the expansion width is inserted into the joint.

The expansion tape is glued using special Teknobond 400 D epoxy glue, which is applied with a spatula 5 cm on each side of the tape. Do not apply epoxy to the middle of the tape.

In order for the tape not to lose its elastic properties quickly, it is recommended to lay it by making a straight or inverted omega. The next day, you should re-apply the material to the tape, paying attention to the high-quality finishing of the edges.


  • It is not recommended to lay the tape in rainy weather.
  • After laying, the tape must be protected from adverse weather conditions, such as direct sunlight, strong wind, high air temperature (above +35°C), rain and frost.
