1. A gypsum panel, comprising:
a set gypsum core associated with a first surface of a first fiberglass mat; and
a substantially continuous barrier coating comprising a polymer binder applied to a second surface, opposite the first surface, of the first fiberglass mat, in an amount of from about 1 lb/MSF to about 40 lb/MSF, such that the substantially continuous barrier coating has an average thickness atop the second surface of from about 1 micron to about 100 microns,
wherein the substantially continuous barrier coating substantially eliminates pin holes present in the exposed second surface of the first fiberglass mat.
