Highly flexible airtightness adhesive sealing tape for interior and exterior use



  • Saves time: no plaster reinforcement necessary
  • Defined transition between vapour check and plaster
  • Reliable joint: reinforcement fabric increases the stability of the adjacent plaster subsurface
  • Construction in adherence with standards: for airtight bonding in accordance with DIN 4108-7, SIA 180 and RE 2020
  • Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme

Areas of application

For airtight seals, e.g. in the skirting area or for penetrations such as pipes, installation parts etc.

Installation instructions

General conditions

The bonds should not be subjected to tensile strain. Press firmly to secure the adhesive tape. Ensure there is sufficient back pressure. Windproof, airtight or rainproof seals can only be achieved on vapour-checking membranes, roof lining membranes or façade membranes that have been laid without folds or creases.

This product can only be worked with if daytime and nighttime temperatures are > 5 °C (41 °F). If the initial bond is not satisfactory, a solvent (e.g. white spirits) may be applied to the grey butyl rubber side of the tape. The solvent increases the adhesiveness of the butyl rubber at low temperatures.

The tape is self-bonding under the effect of heat.


Clean subsurfaces before sticking. Adhesion to frozen surfaces is not possible. There must be no water-repellent substances (e.g. grease or silicone) on materials to be bonded. Subsurfaces must be sufficiently dry and stable.

Bonding and joints are possible on planed and painted wood, hard plastics and metal (e.g. pipes, windows etc.), hard wood-based panels (chipboard, OSB, plywood, MDF and wood fibre underlay panels) and mineral subsurfaces such as concrete, non-plastered masonry or plaster.
Pretreatment with TESCON PRIMER is required in the case of adhesion to wood-fibre underlay panels. Concrete or plaster subsurfaces must not be sandy or crumbling. Pre-treatment with TESCON PRIMER is recommended in the case of subsurfaces with insufficient stability.

The best results in terms of structural stability are achieved on high-quality subsurfaces. It is your responsibility to check the suitability of the subsurface; adhesion tests are recommended in certain cases.
