I will run you through how to permanently fix unsightly nail pops in your drywall. This is a super common problem in most homes but it doesn't have to be a big chore to get things smoothed out and secure. | Everyday Home Repairs

Using the wrong screw is why nail pops keep coming back. When fixing nail pops, the goal is not just to patch the surface. The goal is to secure the drywall to the framing behind it. Inch and five eighths drywall screws are long enough to penetrate the drywall and properly grab the stud without damaging the wall. Shorter screws often fail to catch solid framing, which allows the drywall to continue shifting. That movement causes the nail pop to return even after it has been patched and painted.
