I am renovating a room in our apartment built in 1920. Walls, ceiling, windows, and woodwork. I have removed the wallpaper and now have a nice plaster wall that needs to be skim-coated and then painted. But in one wall, there are sliding doors of the type that go into a channel inside the wall. The wall sections beside the door opening (the part of the wall that hides the doors when they are open) are not plaster but nailed boards.
A previous owner of the apartment made a sad attempt at renovation and put renovation drywall over these, skim-coated the level difference between the plaster wall and the drywall (which is 6 mm), and then wallpapered. Not a very neat solution. Especially not when the drywall eventually came loose from the wall at the top due to improper screwing… Well, now I'm wondering if anyone has any good advice for me? I don't want to put up new renovation drywall because of its thickness. How do I get a good base to skim-coat and then paint?
