Application Notes/Limitations
Primers improve the long-term performance of sealed joints.
Sika® Primer 3N must be used within 30 days of opening the container.

Primers are adhesion promoters. The use of Sika® Primer 3N does not exempt the obligation to carry out correct preparation and cleaning of the joint edges.
It should be applied away from a heat source and preferably in ventilated areas.
