Double-sided nail sealing tape



  • Very good sealing action – liquid butyl adhesives penetrate deep into the lining structure
  • Water resistant
  • Suitable for temporary roof coverings as specified in the ZVDH product data sheet
  • Extra-strong thanks to a reinforcing layer
  • Contains no bitumen


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.

Material Butyl rubber
Release film siliconized paper
Attribute Value Norm
Colour black
Thickness 1.0 mm
Exposure time 6 months, installed under the counter battens
Application temperature 5 °C to +35 °C ; 41 °F to 95 °F
Temperature resistance permanent -40 °C to 80 °C ; -40 °F to 176 °F
Storage cool and dry

Before sticking, subsurfaces should be brushed off, wiped clean with a cloth or cleaned using compressed air.
Bonding 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 have sufficient load-bearing capacity.

Lasting nail-tightness is achieved on all pro clima exterior membranes and other underlay/sarking 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.

General conditions

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.
Waterproof seals can only be achieved on membranes that have been installed with no folds or creases.
Daytime and nighttime temperatures must be >5 °C / >41 °F when working with this product.
