I am going to seal a hole in the vapor barrier. Can I use Bostik SILMAX BYGGFOG 2620 or will it eventually dissolve the plastic? I'm thinking of how, for example, you should use special tape when taping joints.
We have found out that it is Sikas Igas-Pistolet that is suitable for the vapor barrier. The product you mentioned I don't know about, it might work as well
