You can - try Zinsser's Wallpaper Cover-Up which obliterates wallpaper print with a smooth matt, off-white finish and can be overpainted with any conventional emulsion the same day - certainly saves time if you're moved to a new house or business premises.

We've also written a blog post "How to Paint Over Wallpaper" which details how to prepare the surface before painting with Zinsser Wallpaper Cover-Up.
