Friends of ours are moving into their new house and asked if it was possible
to take the wallpaper off with a steamer. Sounds like the paper has gone up
over plasterboard, but wouldn't there be some sort of lining paper? If not,
what's the easiest way so as not to damage the walls? They want to paint
directly onto the plasterboard which I'm dubious about.

I'm tempted to say no just so I don't get asked to do it
