Double-sided nail sealing tape



  • Very good sealing effect: sealing material is pulled into the hole created when a nail or screw is fitted
  • Conforms to regulations: satisfies the requirements of ZVDH and of SIA 232/1
  • Reliable during the construction phase: suitable for temporary coverings during construction work

Areas of application

Nail sealing tape under counter battens for sloped roof structures.
In accordance with the Central Association of the German Roofing Trade (ZVDH), the use of nail sealing tapes in combination with “underlays/sarking membranes with seam and perforation protection” (SOLITEX connect variants) is a required additional measure in the case of “more demanding requirements” (e.g. if the roof pitch is less than the standard roof pitch).
If required, TESCON NAIDECK also serves as a suitable additional measure to create a temporary covering.

Installation instructions

General conditions

Perforation seals will only be effective on roof lining membranes that have been installed with no folds or creases.
Install TESCON NAIDECK with no interruptions between the counter battens and the roof lining membrane. This ensures that perforations that may arise when the roof battens are being fastened will also be sealed.
Adhesion can be carried out to the counter batten or to the subsurface that is to be sealed. Press firmly to secure the tape in place.
Daytime and nighttime temperatures must be >5 °C / >41 °F when working with this product.


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.

Lasting nail-tightness is achieved on all pro clima exterior membranes and other underlay and wall lining membranes (e.g. those made of PP and PET) as well as MDF board and softwood fibre sub-roof panels.

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.
Pretreatment with TESCON PRIMER is recommended in the case of subsurfaces with insufficient stability.
