In a 90 Year old house, plaster walls have spider cracks. They seem to not be into the plaster, but may be just cracked layers of paint. I see a shiny surface in the cracks, so I wonder if it's cracked paint on top of an old glossy oil pain w/o proper prep.
We primed & painted, but the cracks reappear immediately. A contractor skim coated a room & painte, they came back. Not sure what he used.
I don't want to put in the time and effort of using mesh solutions, and definately don't want to tear out the plaster.
Is hanging wallpaper the best and easiest solution, or can some paint or easy roll on type product cover this?
