By far the most frustrating thing about plastering jobs is the drying times. This is especially true with inside corners - with a knife you pretty much can’t do both sides the same day because you’ll always end up messing up the opposite one.
I finally gave one of those corner tools a try, and the result is fucking mint. The customer is going to be so happy with these flawless corners tucked behind the curtains in their living room.
Thanks for the tip - I might give it a try. They seem to be selling a similar product in the local harware store. I use steel corner beads on outside corners but with inside corners I’ve just prefilled and then taped with paper tape just like all other joints.
Yeah its a nice product and the difference is the metal inside corners keep nice and straight if you dont overload with mud. Just dont buy from Lowes! Fuck box stores and their flock camera corporate operations
