Sealing drywall before wallpapering

[trogg]

Hello,

I've got about 100m2 of taped and jointed plasterboard which I need to seal before wallpapering.
I need to make sure that in the future any wallpaper removal will not remove the plasterboard paper facings.
Having had a look around the web two ideas have been mentioned a few times, one of them is painting with a gloss undercoat and the other is to use a drywall/plasterboard sealer... what do you think ?
If both ways are ok then it will come down to price

Or should I be asking this question on the decorating forum ?

Thanks

Thanks Joe for your reply,
had looked at Gardz but wasn't sure about it and where to get it (other than online) where's the best place to get it ? or is it just a case of ringing around the builders and decorators merchants.

cheers
