filling gap in drywall corner
i just put new drywall up in the bathroom ceiling and the room isn't square so i measured everything to cut the drywall the right size.
Unfortunately i measured then forgot to flip it to go upside down on the ceiling. So now i have a gap at each corner of the room. the one side is about an inch wide and the other is 5/8ths of an inch. and they stretch about halfway down the length of the wall until they meet with the wall.

So my question is, how can i fill these gaps?
Can i use expanding foam in there then cover it up?

You need to replace it with the right size but you also need a nailer along that edge. There's nothing holding that edge and if you try to patch it it will crack in no time.

a nailer?
over where it's long enough it goes over the top. is that good enough?

Time for some crown molding.

Cosmetically crown molding would be a great way to cover that corner. However, as jogr said you'll probably want to secure that puppy down as crown would be strictly cosmetic and wouldn't really add to the structural integrity of the new drywall. :thumbsup:

Yes agree you must install a nailer on top of that all. what is supporting the wall from moving, if this isn,t addressed and you fill the gap with new drywall to fit tight, you will have a crack along the ceiling line, there is no support. BOB.
