We just moved into a nearly 150 year old home. In two rooms, wallpaper has been painted. Generally speaking, the paper is in very good condition, and has little or no cracks, tears or bubbles. In one of those rooms, I peeled away a loose piece, and there appears to be only one layer of paper. I do not believe it is a vinyl coated paper. My question is, do I begin to remove this paper, or should I just paint over it, as is? The seams have been overlapped, and as inconspicuous as they are, I know they're there, and feel like it would be doing half the job just to paint over it. On the flip side, we have 5,000 feet to restore, and sometimes I get accused of becoming lost in the details. I need some objective advice!!
