Spackling 90-degree gypsum corners

[tontho78]

Hello. I would need some tips on what to use to spackle 90-degree corners. We have covered a steel beam in the ceiling in the living room with plasterboard and we would like to achieve really nice edges. We are planning to paint it white and we prefer not to use corner lists to hide the ugly seams.

Best regards, Tony
