Plaster Walls: Paper, Priming, Painting
We are restoring a 1920's dutch colonial. We are ready to paint, but have the following issues:
Our walls are plaster and lath, but underneath, there appears to be some type of paper. It's not wallpaper, and I do not believe it is NuWall. It is, however, overlapping and it looks terrible. First, what is it? Second, should it be removed (my inclination is no)?
Also, the walls are horrendously dirty. Are there any products that should (or should not) be used on plaster walls? Also, how about a primer? Some friends recommended Kills (sp?) and TSP but I'm concerned with throwing modern products on plaster walls. Any thoughts?
Thanks in advance for your responses.
