Wallpaper and Wallcoverings - Kilz before?

We're doing a major bathroom remodel in our home. We had to remove about 60% of the sheetrock in the process. The remaining sheetrock had two layers of wallpaper, and as we were removing it, we found what seems to be (from what I've read on this forum) a not-so-unusual phenonenon -- the paper on the sheetrock was wanting to come up with the wallpaper. What we've been left with is a wall with a surface that ranges from bare gypsum to various layers of facing paper from the sheetrock, including a lot of loose flaking paper and some spots where the paper was torn in the process of removal.

Reading other posts here, I see consistent advice of using KILZ on a surface like this. My question is... should we apply KILZ on the raw surface and then skim coat with mud as needed, or do the mud first, then seal with KILZ? Also, anything special necessary where we transition to the new greenboard?

Finally, do we have to use original KILZ, or can we use the latex-based (low-odor) version? It's a small, enclosed area, and the low-odor is preferable if it will work OK.

Thanks!

dancase, You have about got it. Remove whatever loose that will come off. If you want to use the latex version primer it should be alright. At this point when dry it will be ready to patch. Although the oil is a step better I use a lot of the latex in customers homes for the low odor. Make sure you don't have any bleeders(waterstains, lipstick, hairspray) and if you do spot prime with the KILZ Original. Prime the new rock first because you will no doubt pick up pieces of the bad wall that you wouldn't want to transfer to the new...Mike
