Somewhere SW of London. Somewhen before today

'The self-adhesive backscenes fitted last week had not adhered to the wood so were encouraged with some wallpaper paste today'

I have a similar problem with the backscenes in Wombat Creek. Not with dampness,  though. Here it is temperature. With 30+ degrees the self-adhesive backscenes start to create bubbles. They disappear once the temperature drops.
