Installation instructions

General conditions

Perforation seals and water-resistant adhesive joints will only be effective on roofing underlay membranes that have been installed with no folds or creases. This patch can be stuck onto the counter batten or the substrate that is to be sealed. Press firmly to secure the patch in place.

Substrate

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.

TESCON NAIDECK mono patch can be used on all pro clima exterior membranes, on other underlay and breather (WRB) membranes (e.g. those made of PP and PET) and with MDF panels and wood-fibre underlay panels.

The best results in terms of structural stability are achieved on level, unstructured subsurfaces. It is your responsibility to check the suitability of the subsurface; adhesion tests are recommended in certain cases. Pre-treatment with TESCON PRIMER is recommended in the case of subsurfaces with insufficient stability.
