You need a two part contact adhesive.
One is Bostik 2402, although the fact that it has toluene in it means that the seller now has to have a licence and that makes it harder to find.
I have just been using Stomoprene, which is similar but uses acetone.
Both types have a hardener that is mixed in at about 4%, and then they have a life of a few hours. The mix is put on both surfaces and allowed to dry, before the surfaces are brought together.
Two part contact adhesives are used to hold inflatable boats together.
