what is the best glue to use on a 20 mil plastic pond liner?
I originally used a paste-like substance that I purchased with the 20mil plastic. This 2″ wide paste, which was sandwiched between two peices of plastic was supposed to be good for ponds, but it has deteriorated over the last two-years and now my pond is leaking and I need to repair it. Any help would be appreciated.
Thanks!
