Preparation of surface

The surface has to be free from dirt, humidity, ice, fat and other materials, which may reduce the adherence. The DuPontTM FlexWrap NF tape may be installed only in dry environment, where the air temperature is not below 0°C.

While adhering, press the entire surface by hand in order to achieve even adherence.
