Why remove wallpaper?
Maybe your old wallpaper is worn out or maybe it's just time for a change. Whatever the reason for renewal, it's better to have your wallpaper removed before applying new wallpaper. If you don't do this, blisters can appear in the wallpaper and this gives an unattended look. Moreover, it makes re-papering more difficult. The new wallpaper does not adhere well, so you will struggle to apply it.
