Help! I am building a house I designed. I have numerous 135 degree corners, which seemed nice on paper. Now I be drywalling and I have a problem (about 16 of them, actually). How do I deal with these corners, i.e. how do I support the drywall at the corners? At least for the exterior corners I figured I might rip some 2x4s or make a plywood arrangement. I figure the pros have a clever way of dealing such a problem.
Are there any special taping requirements or techniques? The walls are steel stud, if that matters.

Brian, how did you frame the corners? If you have studs ripped at the proper angles, you just hang the board and use metal tape beded in joint compound. I have seen it done with the DW just butted over the void between the studs at the corners, and then tapped. The problem with that method is there is no solid backing beneath the board at the corner. The first time it is bumped,it either cracks the joint or the board. Take the tine to fill the outside corners with blocking ripped to fit,and you will have a nailing surfase for the board. You DW supplier will have the metal tape. There are also some other new products, that I have not tried, that they may reccomend. Others here may have more input.

*Brian- your gonna have to screw some solid supports into the corners. Just draw a plan view actual size and set to work with 2x.be a good idea to have that 2x stock indoors to acclimate for a week or so- longer is better.rip stock to provide your backer and then drywall...
*Dave:the walls are framed with metal studs, so that there is a 2 or 3" unsupported gap either side of the drywall joint. Therefore there is nothing to support the back of the drywall at the edge.Thanks for all your suggestions
*Brian, You are still going to need some blocking ripped and screwed into the void area created by the studs. It is a bear to get them right, but worth the effort. The metal tape is accually two pieces of metal inside of a paper tape. It will fold to any angle for an outside corner. Good stuff. I am not familar with the no coat stuff so can't say how it will work.On another vain. While you have the stud bays open, you should add blocking for your base board if it is going to be wood. Then you can just nail it up when you get to that point. Otherwise you are going to be using trim head screws. They are a pain.Dave
*Get out the old table saw, set the blade at 45 degrees and rip off a triangle from the edge of a 2x4. You should end up with a cross-section measuring 1 1/2"x 1 1/2"x 2". Turn that off-cut around until the long side (2") mates with the 2x4 it just came from. Nail them together. A little glue would help. This results in a solid outside corner using only one 2x4. Attach the 2x4 corner piece to the web of both metal studs (the web side needs to face the corner). See diagram.
*Great sketch Ralph. A picture is worth....

*Thanks Ralph - great sketch. Calvin I'm having a little difficulty visualizing what you are suggesting. Maybe its my vocabulary, but what do you mean by 'tech screw?' Also, I apologize, but I just can't understand the metal blocking on the outside corner.
*Brian, not metal blocking, use wood per Ralph's sketch. Tech screws are hex head self tapping sheet metal srews. They also have self drilling types that work well with metal studs. The hex head gives you a little better surface, like a washer would, and it is easier to drive,because they don't flip sideways on you as easily as a drywall screw.Dave
*Brian, Why not just screw a piece of angle on the side of the studs? Or back the studs up and put in a stud or piece of track flatways? That's how I did mine but I only had a couple. My drywall guy taped with a wider stiffer paper tape,and they came out great.
*Thanks for all the help, everybody
