Cracking Bathroom Paint
 
My bathroom walls have spiderweb-like cracks in them. After scraping them down as much as possible, I spackled over the areas, and then primed with Kilz. When the primer dried, I saw those cracks showing through again. I scraped off the primer I put on, the spackle I just applied, and previous layers of paint from previous owners. Underneath I saw that my bathroom wall layers begin with plaster, then adhesive (for wallpaper), the leftovers of wallpaper backing from 1950's, a layer of spackle, and 3 layers of paint. There are spiderweb like cracks in the spackle that someone laid down 20 years ago over the wallpaper backing. How do I fix these cracks so that they will no longer show through anymore layers of paint?

It's hard to tell the size of the cracks by the description, but since they are returning you might have to do this :

Scrape out all the loose/undersireable material in the area.

Prime the area with a drywall repair primer like Zinsser's Gardz http://www.zinsser.com/images/gardz.jpg

Fill the repair with drywall joint compound then apply drywall tape.

Skim with necessary compound to smooth joint, sand.

Texture wall to match then prime with regular pva primer.

I agree
Scrape, sand, clean, Gardz, skim coat of joint compound (not spackle), sand smooth (and repeat j/c-sand if needed), prime, paint

I had a similar problem in my master bath -- I went for a tuscan look and used joint compound to simulate rough plaster, primed and painted. Looks great and none of the wall paper adhesive problems that I had showed through.

I love the look and it seemed less work than scraping, filling, sanding.
