I've got your typical plaster/lathe walls. It had wallpaper - then paint - then wallpaper on it, until my wife removed it all to bare plaster.
I've drywalled before(and have a large container of mud in the basement), but never plastered. Can I skim coat a layer of the mud (joint compound, mud, drywall, whatever you want to call it) directly over the plaster, or does it have to be plaster on plaster?
We plan to paint the finished product.
