Can you put new wallpaper over the old paper backing of the old wallpaper?
I stripped old wallpaper from a bathroom but found out that the previous owners put plaster over parts of older wallpaper underneath and the paper isn’t coming off easy. Would new wallpaper cover and stick to the old wallpaper (backing). I got the top layer off before finding all the problems. Half the wall has the paper backing on it still. I was going to paint but no way I can do that now without even more work.
I can’t sand the wall down because the plaster that they did to hide parts of the old wallpaper before is very uneven and and has big hunks in it. I would have to replaster the whole wall to make it even. Its a mess.
I have seen this done, infact when I went to take down some wallpaper in my home, there was several layers of diffrent kinds of wallpaper through the years.
Have you tried sanding the wall paper so it looks even?
(So that maybe you could put a primer down and then paint)
Use a wall primer and then wallpaper over it. This is not the same as primer paint – it is a liquid that you wipe onto the wall before wallpapering. I used it in a similar situation a number of years ago. Your wallpaper store or home improvement center should be able to help.
