Spray­able primer

 

Advantages

  • 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 load-bear­ing ca­pa­city
  • 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
 

Application

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).

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 adhesive residues. Wipe off any adhesive 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.
The valve can be set to three levels (L-M-H).
