A: No, this is a pre-formed butyl cord with no cure time required—installation is immediate once properly primed and seated.

Q: What storage conditions and shelf life apply to this product?
A: The sealer should be stored in a cool, dry place at 15–30 °C. Shelf life is 48 months from the date of manufacture under these normal storage conditions.
