We have an 1810 Federal home and have gotten to wall painting. The wallpaper is only one layer, and pulls off easily with no water or additives. BUT, underneath is raised, dried glue, I tried to get it off with hot water...and this DOES work...but with the scrubbing also comes the plaster and now there is exposed hairs sticking out? Should I go about this different? The walls are in such great condition I sooo dont want to ruin them. Should I try a little vinegar instead in the water? Or avoid the scrubbing altogether? I was planning on putting on an oil primer and then a latex paint...but I am thinking the hairs are going to show....HELP!
