Hi, we have just stripped the wallpaper off the walls in our living
room, however a lot of the facing paper of the plasterboard walls have
been ripped. To get them smooth again someone has suggested sanding
them down, coating with a vinyl silk emulsion, sanding again, filling
then lining to get them smooth again and someone else says sand them,
line them then put a skim of plaster on them. What is the best idea?
Would the plaster not come off the lining paper?

thanks
