Painting problem

[Nite Owl]

We are redoing the half bath, it had wallpaper which was pretty easy though tedious to remove. I used Diff for part of it then used just warm water and it worked just as well. When we got the paper off the walls were sponged down. So we figured the hard part was done and started priming. What a mess! The primer is peeling off and the part that sticks looks like orange peel. It's almost softening the wallboard under it too. We didn't put the wallpaper up but the walls look to be builders white paint in good condition. The primer is a latex. Could the paint be oil based? Did the wallpaper paste not all come off? There is no moisture in the bathroom so I thought a regular primer would be ok instead of Zinnser or Kilz, there is no window and the latex was supposed to easier on the breathing, do I need to go with that? Would a light sanding help?

1. this may sound like a stupid question, but how long did you let the sheetrock

dry before you started priming?

2. A few days

I hurt my back and didn't get to it right away so it was dry.

I just looked at it and it is sticking but looks awful, or some of the wall does, some of it is ok. It's all bumpy. The rollers were new. It's a little 5x7 bathroom, it was supposed to be easy! The primer is Valspar latex from Lowe's.

3. hmmm, I wonder if there is still some glue on there. check out this link and see if it helps

I'm wondering if the water based latex paint 'reactivated' the glue residue?

4. I think the clue is in the "almost softening the wallboard"

Would recommend you remove as much of the primer as you can (pull/strip and/or lightly sand medium grit). Sounds like the sheetrock needs a remud before you go to next step of painting. Often stripping wallpaper pulls off the protective joint compound/mud cover that keeps sheetrock from being porous.

Below are sites that give excellent "how to" info re: applying joint compound on sheetrock

5. Went back to Loew's

the guy immediately said there was still glue on the walls and the primer activated it. He said to wash them again with the Dif. We did that and are doing a sanding. Will try again with the primer after they are dry. Wish us luck!

7. You sure were!

Did the priming and they look great. Well at least normal!

Will paint in a couple of hours then hopefully we can get the toilet back in tonight. My sons friend is helping with this, really we are helping him, and his wife is due with their second child any minute. We have other bathrooms but this is the only one on this floor and I'm getting too old for all these stairs.
