re: #22 A Mom Anon

Had an “Oh Noes!” moment today. Removed 50-year-old paneling from one wall, filled holes, primer, and paint, easy peasy. Next wall, removed paneling to discover 62-year-old wallpaper on the wall. Some say use oil-based primer and then paint. Some say 1/4” drywall, tape, mud, then primer and paint.

I really have no idea.
