The wallpaper job from hell continues.

Calling all home repair people, full alert.

Remember that wallpaper job?

Yes, it's still going on.

Since S.'s grandmother came home unexpectedly, I couldn't spend the night there anymore. We were reduced to working on it when our schedules overlapped: he works 10-6ish, I work 3-9:30ish, so project work time shrank to 10pm-midnight.

My fall-bounce-bomp down the stairs delayed it further. Then I got a cold.

The ugly wallpaper came down over Christmas, revealing those horrifying Pepto-Bismol pink walls. It took two coats of primer (high quality Zinsser) to cover that pink. The walls had both coats of primer and were painted January 10th, done ...

... except for the crack down the wall we'd discovered behind the wall paper and the closet doors. That corner I mudded (I'm no expert at mudding), sanded, and primed.

Annnnd the primer cracked like lizard skin along the vertical part of the crack.

Huh.

I assumed I must not have let the mud dry (but 24 hours should have been enough...), talked to the guys at Home Depot, who'd never seen anything like it but thought my explanation was plausible. They told me I'd have to scrape it out and re-mud. I said, "Oh, god, I hope not."

I scraped and sanded the cracked primer and mud. With a sanding block it was total gorilla work.

Sanding hard, I leaned on the wall -- and broke the mud. After all that sanding, I was going to have to redo it.

Got sick, got injured, painted the closet doors to keep the project moving while I couldn't sand. Got snowed in.

Finally bought a palm sander and set to work on it this weekend. I stopped trying to have the work be perfect and asked S. (home renovator-in-training) to do the mudding of the part that broke. He put on waaaay too much, but hell, he sanded it.

Then he did the same thing. He leaned too hard on the wall on the upper portion, breaking the mud there. So that had to be remudded as well.

Sunday it was done. Sanded smooth. Ready to paint.

I primed it.

And the damned primer cracked like lizard skin again. The seam underneath it is smooth. It's just the primer cracked on top of it.

Pissed, I laid on coat after coat of primer (yes, I waited an hour between coats, no, I didn't sand between coats, not with that lizard skin problem). It cracked less. But it still cracked.

Home owners and painters ... any ideas? We're stumped. S.'s forums are stumped. The Home Depot guys are stumped.

Suggest this product:

-- light, highly adhesive, sands brilliantly when dry -- go a little shallow and then Spackle over it -- before using it clean the area well, degrease it because won't set over oil or grease -- rough sand if clean -- before applying. It will stick to your tools, btw, so use water at a release agent when applying and clean tools immediately -- it it hardens on tools Acetone takes it off.

When dealing with my own wallpaper removal from hell project, I ran into slightly different problems, but to deal with cracking issues I painted the patches with an exterior primer (small can specially for priming damaged exterior siding, don't remember brand) and after it had dried primed the entire wall with the interior primer over that. You issue sounds slightly different, but it may be worth trying.

Good luck.

I showed this to my local home-repair expert, and she suggested:

1. Use real spackle, not the light-weight stuff. Layer it in and let it dry THOROUGHLY between layers.

2. Use a screen, not sand paper. Sanding is simple with a screen.

3. Try painting, again.

Yeah, spackle isn't designed to be laid on in thick layers -- if you do that, it takes forever to dry (at least a few weeks). So the problem is likely that the spackle is still wet, and it's reacting with the primer chemically in some fashion.

Get the good spackle, and apply in very thin layers, one at a time. Wait 24-48 hours in between each application, sanding each time. You'll probably want 4-5 layers, or however many it takes to make the crack disappear. Wait 48-72 hours after the final application, sand, prime, and paint. Should work that way!

(Sorry for the late reply!)

Yeah, our walls are plaster over particleboard (not drywall), so there are a bunch of settlement cracks everywhere. For now we're just leaving them and we'll start the spackle process when we have the energy!

Plaster over MDF was really common in the 50s, actually! it was the step between lathe-and-plaster and drywall.

And sure, toss me the info and I'll see if we're free/interested!
