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

While the weather is set to rain, get as much steam into the room as is
possible. Pots of boiling water, as many electric kettles you can find,
steamer going full blast, until you think you are in a tropical forest.

You will now find that the paper will almost drop off the walls without
a scraper being used.

Oh! I forgot. Do this very early morning, or late at night, assuming
that there has not been any heating in the house. If there is heating
on, even at this late stage in the year, turn it off and open all doors
and windows for several hours before bringing up the steam levels. This
way, all the walls will be as cold as you can make them and the steam
will condense all the more onto them.
