The BONDING ADHESIVE WB is a water-based adhesive for bonding STRUCTASEAL® EPDM roofing. The adhesive should be applied to a flat horizontal surface. It is an adhesive without solvents so it is not suitable to use on all surfaces. The STRUCTASEAL® BONDING ADHESIVE WB requires an absorbant surface such as timber. Because the adhesive is water-based it is easy to apply and during installation it is also possible to partially correct it after application.
This adhesive can only be used on absorbant surfaces in the central zone of the flat roof and there is also a limitation to the height (max. 3.00 mtr). Roofs at a height above 3.00 mtr must be adhered with the PU Based variant. In practice this adhesive is often used on roofs of carports, garden houses and shed roofs. The Bonding Adhesive adhesive products should not be used for adhering upstands and edge zones.

For bonding STRUCTASEAL® EPDM Roofing on absorbent surfaces such as timber constructions.
Place the EPDM roofing completely on the absorbant surface (e.g. timber roof deck) and let it relax for 30 minutes. The surface must be flat, clean, grease-free and dry. For optimal adhesion, walk through the following points step by step.
Half fold back the EPDM roofing.
Apply the KS217 adhesive to the wooden timber surface (apart from the last 150 mm and the upstands).
Roll the EPDM directly back into the adhesive on the roof surface.
Brush the EPDM roofing lightly with a soft broom. Repeat the above steps for the other half of the roof surface.
Adhere the remaining 150mm of the roof surface and the upstand edges with the CONTACT ADHESIVE SPRAYBOND.
Storage at +5 °C to +25 °C.
