Solvent-free primer, no drying required



  • No drying required - adhesive can be applied straight to the damp primer on absorbent substrates
  • Deep penetration of the primer, excellent hardening
  • Application even on damp substrate
  • Can also be used in the event of frost
  • Can be used with any pro clima adhesive tape
  • Solvent free


Wash primer for wood, wood-fibre boards, masonry, roofs, walls and ground slabs for subsequent adhesion with pro clima adhesive tapes such as TESCON VANA, TESCON PROFECT and the EXTOSEAL range.

Before primer is applied, subsurfaces should be brushed off, wiped clean with a cloth or cleaned using compressed air.
Frozen and soaked subsurfaces are not suitable for the application of primer. There must be no water-repellent substances (e.g. grease or silicone) on the subsurface.

All mineral surfaces (e.g. plaster or concrete) and (used) timber subsurfaces can be pretreated. It is also possible to strengthen porous materials such as wood fibre underlay panels.

Permeable absorbent subsurfaces (e.g. wood fibre underlay panels) may be slightly moist. In this case, the adhesive tape to be used can be stuck directly onto primer that is still wet. The product achieves its final level of strength only when it has dried. It may be advisable to use covers to protect the area that has been treated. Primer that has not yet fully dried must be protected against the effects of the weather.

If butyl rubber tapes (e.g. EXOSEAL range) that hinder diffusion are stuck onto relatively well-sealed, non-absorbent subsurfaces (e.g. concrete), the primer must first be allowed to fully dry before the adhesive tape is put in place.

Only ORCON CLASSIC or ORCON MULTIBOND can be used when applying primer for joint adhesives. The primer and ORCON CLASSIC must be fully dried (1-2 days) before the membrane material is stuck in place (dry process).

General conditions

Shake or stir the can well before use. One litre of primer can be used to treat an area of about 4.5 m² (48 ft²).

For particularly quick and easy application insert the 1-litre dispenser bottle in to the TENAPP application tool.
Advantages: Application and distribution in just one step, using just one hand and no contamination of the primer in the container.
