Fire rating on column

I have columns in an area requiring 2hr fire rating and I've seen details that use gypsum to wrap the column to maintaining the 2hr rating on these. The detail only shows the gypsum with corner beads in the column corners and no reference to firestop sealant. In my case, I would like to use a 2hr fire rated material (per ASTM E119) to clad the room including the columns, but I don't don't know if the corners where the ends meet would require a filler material with firestop sealant or if a filler material with metal trim is ok.
