What is the shelf life on the tubes of Sikaflex (Date on tubes) Thanks, R> Ross

The shelf life from my expierance is very short. Depending on how old it is when you receive it. But on average an unopened tube will last about a month. But we do not keep ours in a controlled climate. I would think if it was kept indoors in a climate controlled inviroment it would last longer. How much longet, I do not have that answer. But as stated we get about one month.
