Sprayable primer for interior and exterior use
- Easy to apply – spray on directly from the can, no contamination of the primer in its container
- Secure bonds: penetrates deep and strengthens dusty subsurfaces or subsurfaces with insufficient stability
- Saves time: adhesive tapes can be stuck to absorbent subsurfaces with no drying time
- Flexible use: use on dry and slightly moist subsurfaces
- At any time of the year: can also be applied during frosty conditions
Areas of application
For preparation and improvement of subsurfaces for subsequent adhesion with pro clima adhesive tapes such as TESCON VANA, TESCON PROFECT and adhesive tapes in the EXTOSEAL series. Suitable for wood, wood-fibre boards, masonry, roofs, walls and ground slabs.

The quantity used may vary depending on the substrate and application method.
Shake the can well before application. The fan-shaped spray jet can be adjusted in the horizontal and vertical directions by turning the spray head nozzle. After every spray application, spray the can upside down until only blowing agent comes out so as to avoid blocking the valve riser tube and the spray head with primer residues. Wipe off any primer at the outlet of the nozzle.
Spray the surface to be stuck after cleaning it – spray distance 20 - 25 cm (8" - 10"). Allow to ventilate for between 5 and 15 min. (depending on material and application). Repeat this procedure again for absorbent subsurfaces.
Before primer is applied, clean the subsurfaces. 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 pre-treated. It is also possible to strengthen porous materials such as wood fibre underlay panels. The primer contains solvents. Subsurfaces are to be checked for compatibility, if necessary.
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).
