The easiest way to tell if a nail pop has occurred is by looking for small open holes in your drywall. Sometimes, a popped nail may not get all the way through the drywall. In this case, you will find a small, raised bump on your drywall, and you might also notice cracked paint around the area where the popped nail is located. Any small imperfection in your wall is worth a closer look to confirm whether or not it is a popped nail.
