I know, I know, its bad and normally I would never do it and Zampa's going to shout don't bother. But, the owner of a flat wants me to try it and is aware of the problems that could arise. There is a (silk) painted vinyl wallpaper on at the moment and she wants it covering with a blown vinyl type paper. What would be the best way to go about this? What paste should I use, the ready mixed stuff? Any advice would be great, thanks.
