Adhesive tapes & sealants

Adhesive tapes are suitable for smooth, even substrates such as PE film, OSB and timber – they bond over a large surface and are quick to process. Connection adhesives such as Orcon F or Folien-Fix are better for rough, absorbent or uneven substrates like concrete, plaster and masonry – as well as for permanently elastic connections that need to accommodate movement.

Primer significantly improves tape adhesion on absorbent, porous or difficult substrates such as calcium silicate blocks and porous concrete. On smooth substrates like timber and PE film, primer is generally not needed. If in doubt: it is better to prime once too often than not enough.

Kompri joint sealing tapes are pre-compressed foam tapes that expand to the intended joint width when installed. They seal joints between building components with permanent elasticity – for example between window frames and masonry, or between different building materials that settle differently.

Grommets (ROFLEX for pipes, KAFLEX for cables) are pre-formed solutions that are faster and often more reliable than taping. They are particularly suitable for multiple penetrations and where time and reliability are critical. Tape is more flexible for unusual geometries.

Liquid airtightness (CONTEGO, sprayable airtightness) is used wherever membranes or tapes cannot be applied – on very rough substrates, hard-to-reach areas, gaps and complex geometries. It is brushed or sprayed on and forms a permanent airtightness layer after curing.

For the system guarantee, yes. Targo recommends Targo adhesive technology with Targo membranes; pro clima recommends pro clima products. Many cross-brand combinations work well in practice, but the system guarantee lapses. In case of doubt, stay within the system.
