How to fix my drywall problem
It's my last room to paint on the first floor. But it's covered by wall paper. So I used the solution and tools to remove wall papers. Because my floor is hardwood, so I didn't sprayed much solution. When I removed wall papers, some brown papers on the top
of drywalls were off too. I didn't care about this, because I thought the primer I would use can fix the problem. Then I tried Kilz2 interior/exterior water based primer-sealer-stainblocker a bit. I tried this product a bit. No, the primer can't fix the problem. The surface still looks very urgly. If the edge of the brown paper loose and I put the primer on it, it can pop out. Now the drywall has most of the original old primer off and many brown paper off spots. I was thinking to use skim coat, but i don't know if this is the right way. Can anybody please give suggestion so I can fix the surface a quick as possible and I can apply water based paint later.

If you have any exposed gypsum - it needs to be coated with either an oil base primer or Zinnser's Gardz!! That prevents the water in latex paint or joint compound from curling up the paper around the edges. The primer will also keep any adhesive that might still be on the wall from being a problem. After the primer coat is dry, you may need to sand or skim coat to get an even surface. You can prime those repairs with latex.

Mark nailed it - Zinnser Gardz followed by joint compound to smooth the wall and then regular primer and paint.

Gardz is just for the exposed gyspum before you put joint compound over it - it seals the gypsum so moisture does not move from the joint compound to the gypsum.

Mark is right, you can do either - I interpreted your question as being where you had to prime with Gardz and Mark took it as where you can use Gardz.

Thanks all the valuable responses. I'll use Zinnser Gardz then joint compound then the water or oil based primer ---- as you guys suggested. I'll post my feedback after I finish. Thanks again.

No need for an oil base primer over the j/c. Oil base was the old standby for priming over damaged drywall. Zinnser's Gardz is the only latex primer that can be substituted for the oil primer. Once the damaged drywall has been sealed with the Gardz - there is no need for an oil base primer. While the j/c could be primed with oil base, latex is so much easier and user friendly
