The cause of the wall coverings failure, is not the foam.
Airstream was forced to use a "water based" adhesive, which is the real culprit.
Same sort of thing happened to the cars years ago that were painted with a water based paint.
Our Feds were the one that caused those issues.
The only permanent fix, is to remove the covering, clean up the walls, and then install new covering. The original covering cannot be successfully salvaged.
