Actually this isn't entirely a response to this question. It is another question and some relevant info to this post. I had my LR/DR and hallway nail pops fixed and the whole thing primed a year and a half ago. Several of the walls felt damp for almost 2 months. They did 2 coats. They used Behr primer, which did not even cover pencil marks completely, and looked to be watered down. Still almost 2 years later, if I put the blue delicate tape on the wall in a lot of spots, the paint pulls up. If I lean a heavy picture against the wall and leave it for a couple of days the same thing happens, and the paint will usually pull of the wall in that case.
]Any suggestions as to what I can do about this?[ My assumption is from other posts, that they did not clean the drywall dust off the wall. Perhaps did not sand the whole wall either. My gut feeling is, I need to sand the entire wall, clean up dust, and reprime. This was a reputable company who specializes in drywall. BTW I have only used one other Behr paint, and was not happy with it. Outdoor paint with Primer used on my shed. Used 2 coats. It turns white when scratched. For example, where I have Christmas Lights up. I know others swear by Behr, but give me my Kilz and Valspar.
