Interior adhesive

richam02

Wonder if anyone call help or advise on this one? The wall covering in my motorhome is lifting in a number of places, particularly the thin 2cm strip that covers the join of fabric. Think this may be due to temperature rise. Ive tried gently pressing and will hold for a few hours before peeling back again. I think I need to glue in order to secure but am uncertain which adhesive to use and was wondering if any fellow members have experienced similar problems and what can be recommended. Many Thanks.
