Application Advice

In­side: Air­tight bond­ing of va­pour check and air­tight­ness mem­brane as well as air­tight wood-based pan­els. 

Out­side: Air­tight bond­ing of roof-moun­ted va­pour check and re­fur­bish­ment va­pour check and air­tight­ness mem­brane. Wind­proof­ing of sark­ing mem­brane, roof lin­ing mem­brane and wall lin­ing mem­brane (e.g. pro clima SOLI­TEX). Wind-proof bond­ing of wood-based pan­els used as sark­ing boards. 

All bond­ing, in­door and out­door, can be between the same ma­ter­i­al as well as with ad­ja­cent struc­tur­al com­pon­ents with a smooth, non-min­er­al sur­face (e.g. pipe pen­et­ra­tions, roof win­dows). 

Substrate - Be­fore stick­ing, sub­sur­faces should be brushed off or wiped clean with a cloth. Ad­he­sion to frozen sur­faces is not pos­sible. The sub­strate ma­ter­i­al must be free of wa­ter-re­pel­lent sub­stances (e.g. grease or sil­ic­one). Sub­sur­faces must be suf­fi­ciently dry and have suf­fi­cient load-bear­ing ca­pa­city. 

A per­man­ent bond is achieved on all pro clima in­door and out­door mem­branes, oth­er va­pour re­tarder and air­tight­ness mem­branes (e.g. PE, PA, PP and alu­mini­um foil) as well as roof and wall lin­ing mem­branes (e.g. PP and PET). 
Ad­he­sion and joints can be car­ried out on planed and painted wood, hard plastics and met­al (e.g. pipes, win­dows etc.), hard wood-based pan­els (chip­board, OSB and ply­wood pan­els, MDF board and soft­wood fibre sub-roof pan­els).

Wood fibre sub-roof pan­els re­quire pre-treat­ment with TESCON PRIMER RP be­fore bond­ing. 

The best res­ults in terms of struc­tur­al sta­bil­ity are ob­tained on high-qual­ity sub­sur­faces. 

It is your re­spons­ib­il­ity to check the suit­ab­il­ity of the sub­sur­face; ad­he­sion tests are re­com­men­ded in cer­tain cases.

Limiting factors

The bonds should not be subjected to tensile strain. 

After sealing the vapour retarding membranes, the weight of the insulating material must be borne by lathing.

Adhesion should be supported by battens if necessary. 

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. 

Ventilate regularly to prevent build-up of excessive humidity and use a dryer if necessary.

  • All-round ad­hes­ive tape for in­tern­al and ex­tern­al use, 6 months out­door ex­pos­ure 
  • Easy to tear off by hand with the soft fleece back­ing
  • Can be plastered over 
  • For air­tight bonds ac­cord­ing to DIN 4108-7, SIA 180 and OENORM B 8110-2 
  • Low­est VOC rat­ing in haz­ard­ous sub­stance test
