I am currently in the process of redecorating my daughters bedroom in my new flat. When i stripped the old wallpaper it came down with no effort at all but has left flaky pieces of old paint all over the walls? The walls are plaster underneath the flaky paint so there was only one layer of wall paper. I am planing to hang wallpaper again but don't think it would be a good idea to wallpaper over the flaky paint. What would be the best way of preparing the walls for wallpapering. Thanks in advance.
