When I bought this house 6 months ago, every wall, in every room, was covered in a very thick heavy blown vinyl. And then painted in God knows how many coats of paint and those awful 1980s dado wallpaper strips near the ceilings. I hated it and decided to strip it all off with a steamer. Even as the paper was easing off the walls, I could hear chunks of 1970s plaster falling off the walls. I ended up having the whole house replastered and skimmed. There is no way that wallpaper is going back up whilst I live here! Paint in a water based emulsion every time. So much easier to clean and paint over.
