Pro Clima ROFLEX 150 - Seal­ing grom­mets for pipes Ø 120-170 mm - 25x25cm - 2 pieces

Substrate

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 all pro clima in­teri­or and ex­ter­i­or mem­branes, oth­er va­pour re­tarder and air­tight mem­branes (e.g. those made of PE, PA, PP and alu­mini­um) as well as oth­er un­der­lay/sark­ing and wall lin­ing mem­branes (e.g. those made of 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 and smooth min­er­al sub­sur­faces re­quire pre-treat­ment with TESCON PRIMER RP 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 RP is re­com­men­ded in the case of sub­sur­faces with in­suf­fi­cient load-bear­ing ca­pa­city.

General conditions

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