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.
As another DIYer for mudding and taping, what I’ve learned is that less is more. Better to do 5 wafer-thin passes with virtually no sanding than 2 passes and sand like a sumbitch because it’s full of bubbles.
This is a good tip, thanks. I have been approaching it with a “I’ll build up a ton, then sand it back to what I need” which is probably one of the many ways I mess it up :)
That’s how I started out, too. Not only does it take forever to dry, it’ll crack and slump. And then, of course, there’s the interminable sanding.
You can also play with the later coats, going with a thinner consistency so it fills the little holes better and you’re scraping most of it off. Watch a few youtube channels of pros, it’s time well spent to save time later.
