1. Clean the subsurface
Subsurfaces must have sufficient stability and be level for permanent bonding to be achieved.
Remove any dust or wood shavings from the subsurface (brush off).
2. Adhesive bonds at roof valleys
Pre-treat wood fibreboards with TESCON PRIMER and create adhesive bonds in the area around roof valleys, ridges and panel joints (if necessary) using the TESCON VANA system adhesive tape.
3. Bonding to chimneys
Mineral subsurfaces such as plaster, concrete or similar surfaces can also be pre-treated with TESCON PRIMER and then bonded in a reliable manner using TESCON VANA.
When plastering over the adhesive tape, please observe the recommendations of the plaster manufacturer for non-absorbent subsurfaces.
A bonding course may be necessary.
4. Bonding with underlay membranes
Pre-treat wood fibreboards with TESCON PRIMER, stick the TESCON VANA all-round adhesive tape onto the wet primer and to the underlay membrane, and rub firmly in place. You’re finished!
5. Bonding at skylights
Adhesive bonds with TESCON PRIMER and TESCON VANA seal the transition between wood fibreboards and the deflector channel above the skylight in a reliable, waterproof manner.
6. Detail: Pipes
Ventilation pipes and other similar round penetrations can be bonded to the pre-treated panel using pro clima ROFLEX EPDM sealing grommets and TESCON VANA.
