I have room where a prior tenant had applied latex paint over a horsehair plaster wall without priming first. There are some adhesion problems - not so much on the vertical portions but on the sloped portions (this is in a third floor bedroom). And perhaps this person did not allow the wall to dry properly before applying the paint as well, who knows. Given that there had always been wallpaper on that wall and never paint, I'm not concerned about lead so my thoughts are that the only way I can deal with this is to sand the latex paint off. Would you suggest renting a drywall sander for this task? I've never used one before, so I don't know a ton about such devices. Would that be gentle enough for an old horsehair plaster wall? I wouldn't want to sand it by hand - it would be a horrible task not to mention the awful dust mess that would produce. I really just want to paint this room - I don't want to spend weeks removing 5 yr old latex paint lol, but I do want to do this properly as well.
What are your thoughts? Thanks!
