10 Questions You Should to Know about sourcing drywall corner bead types

I would probably just go with the metal for the outside, its most likely the easiest to DIY.You can go with paper with metal for the insides if you want. Even paper with metal for the outside isn't that bad.If you're asking this question, to do a full corner I would not recommend using 45min mud. Its most likely just too fast drying for your skill level. Even 90 mins might be too fast for you.I would likely just get a bucket of normal premixed mud, and a mixer. Then you can add a bit of water each time and mix it to the right consistency. Yes, that is right, you still need to add water and mix premixed mud in most cases. Again, stuff like this with a 24 hour dry time is better when you're new.Also, just one last tip. The inside corner bead is pretty easy, but for the outside corner bead you have to make sure it doesn't twist. After you put it on the corner, check in a bunch of stops, top, middle, bottom, that on all sides when you put your knife resting on the bead as well as the wall, you can see daylight. If you can't see daylight everywhere, the corner bead has twisted and needs to be repositioned. If you don't have daylight your corner bead doesn't really do anything.

Question on paper corner bead…what’s the secret to setting outside paper corners??? I know the “pros” use a tool to “set” it in a bed of mud. Don’t do a lot of this but enough to want to get better finish/quicker at it. Is the tool the secret?

Currently, I have been pre-mudding the corner, setting the bead, adhering the paper with a taping knife…let dry, then loading the corner. Most areas are OK but the occasional section has either not enough mud or I scraped to much out when trowelling causing areas that don’t “stick”. It all looks good till the next coat and paper bubbles where not stuck!! (now visualize trowel, hawk and mud now flying across room followed by lots of profanity)
