Wa­ter bear­ing ad­hes­ive con­nec­tion tape with high ad­he­sion strength



  • Pro­tects struc­tur­al ele­ments from wa­ter in­gress: wa­ter­tight and blocks rising damp
  • Ex­tremely high ad­he­sion even to slightly damp and cold sur­faces
  • Very elast­ic: can ad­apt flex­ibly to sub­sur­faces and corners
  • Bonds to min­er­al sub­strates
  • Seals nail holes
  • Low­est VOC rat­ing in haz­ard­ous sub­stance test


Wa­ter­tight ad­hes­ive tape with high ad­he­sion for cre­at­ing self seal­ing sill flash­ing, for join­ing wood-based pan­els to smooth min­er­al sur­faces, to stick sub-roof pan­els one be­low the oth­er (e.g. in grooves and trans­itions) and to bond these to ad­join­ing struc­tur­al ele­ments.

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

Per­man­ent ad­he­sion is achieved on wood­based pan­els (chip­board, OSB and ven­eer ply­wood, MDF board and wood fibre sub-roof pan­els).
Wood fibre sub-roof pan­els and smooth min­er­al sub­sur­faces re­quire pre-treat­ment with TESCON PRIMER be­fore bond­ing. Con­crete or plaster sub­sur­faces must not be sandy or crum­bling.

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 load-bear­ing ca­pa­city.

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 retarding membranes, roof lining membranes or façade membranes that have been laid without folds or creases.
The tape is self-bonding under the effect of heat.
