I've got a couple nail holes from pictures being hung in the garage that I'd like to patch. The drywall is 5/8" fire-rated. With that in mind, are there any special considerations when patching this wall? Should I be using fire caulk/foam or just use all purpose spackle on it as if it was any other drywall?
Just as minor voids left during hanging of the drywall are filled with joint compound, you can do so with nail holes and any other minor penetrations. Many times an installer will miss framing with a screw and pull it out, leaving a similar hole. It's not a concern.
