I have an interior bathroom(only exhaust fan outlet to air) that I painted with KILZ latex multipurpose primer.

The room had old wallpaper on it that came off very easily. the glue that did remain had taken on what was like the texture of very thin translucent paper. The sheetrock was very dry. I spackled a few spots and applied the primer.

The sheetrock in small sections rippled (which I assumed was the paper absorbing the moisture) and in one other spot just came off the underpart of the sheetrock when the roller moved over it.

After finishing the room, it smelled pretty bad and was difficult to work in. Two days later is still smells. I have had the exhaust fan on and an ozone air cleaner going and it still smells.

I am wondering if the interaction of the primer and the old sheetrock caused the smell, but more importantly, what can I do about it. I've thought to try a different primer (Zinseer?), but don't know if that will work.

Thanks for your thoughts.
