Cover Cracks with Wall Liner
Wall liner is basically wallpaper, but its much thicker and paintable. Read more about it here.
Home improvement shortcuts usually lead to trouble. But not always. Fifteen years ago, I tore out most of my crumbling plaster walls and replaced them with drywall. By the time I got to the dining room, I just couldnt face another day of dust and rubble. So I took an easier path: I patched the worst cracks with mesh tape and joint compound and primed the walls. Then I covered the walls with wall liner. Today, those walls still look perfect.
Wall liner is basically wallpaper, but its much thicker and paintable. Some versions are smooth; some have a textured or patterned surface. Ive seen situations where severe cracks telegraphed through it, so patching wide or loose cracks beforehand is a good idea. Aside from hiding cracks, liner is also used to smooth out textured walls before hanging wallpaper. And its the easiest way to cover up dated wall paneling.
