Repairing torn drywall paper - is shellac-based primer necessary before spackling?
My roommate is leaving my apartment and had applied many strong adhesives that took off parts of the drywall with it when removed, exposing the brown paper underneath. There are a lot of these areas all over the walls, most of them no more than 2 or 3 inches. He assured me that he used to work construction and it's a simple fix. As we were prepping to repaint, he spackled over the brown paper spots just like any hole that might be left from a screw. The next day, I noticed that the edges of these areas were still definitely raised (in the edges where the paint was torn from paper). I wasn't sure if enough spackle had gotten into the area or if a coat of primer would fill that right in, so I googled what the best method for dealing with torn drywall was. I saw that before putting any wet material on the dry paper, you're supposed to seal it with a shellac-based primer, so the paper doesn't bubble up and create a blister. The majority of these areas seem fine. There's one area where it looks like a blister may be forming, but I can't be sure. We used Red Devil Onetime Lightweight Spackling. I haven't applied any primer or paint yet. Should I go back and attempt to scrape off the spackle to seal the areas first and redo the spackle job? Is it too late? If most areas dried okay, should I just go ahead and prime and paint without using a sealant for the exposed paper areas?
Thank you!
