I have two ceiling holes which I'm looking to repair. The ceiling plasterboard is 13mm thick and the hole's dimensions are shown in the pics below. I'm trying to decide which option below will give me the better long lasting result:
(1) add a backing and simply fill the holes with joint compound and paper tape
OR
(2) cut it out as a square, add a backing, insert a 13mm thick plasterboard piece, then fill gaps with joint compound and paper tape.
Keen to hear the community's thoughts. Thank you.
