how do I frame odd outer angles?

Can anyone tell me how I should frame outer angles like pictured below? Is what I drew below correct? It will actually be 2 layers of 5/8" drywall... and i'm not sure how to avoid having the 2 seams on top of each other.

I would caulk it + mud & tape each layer.

Doing it that way would make a very weak joint that would most likely fail at one point or another. I would cut the header and footer to the angle you need for a butt joint.

Yeah what they said PLUS There are photos somewhere on here of someone laying out there inner frame walls, my plan is similar to what I saw in those photo's and would be something like: 1. Mark out with chalk on floor the walls. 2. Cut the sole plates for entire room, lay on ground. Where walls make angles, cut one or both sole plate for angle so that there will be no gap. 3. Make top plates duplicating exactly the sole plates. 4. Assemble walls. THEN with the drywall most of the time we will be installing over an inside corner so it don't matter BUT if installing over an outside corner like in above pick then JAM the space between studs with Rock-wool, then add drywall OR if your up for it rip down the stud to fit (and then if still left with a space, jam with rock-wool) Depending you MIGHT be able to slightly overlap the drywall, MAYBE a drywall rasp will get a smooth angled edge on the end of drywall, won't be much of an overlap, but some is better then none. AND remember I'm just a "wanna be" not an expert. Marc

What Marc and the others said, but I would definitely try to back the very corner with a stud or two, cut to fit. On outside corner like that usually takes a lot of hits (while moving furniture, and such), and I'd rather end up with a dent in the drywall than a hole. I'll have at least one such corner in my build. - Andy

I agree. I'm pretty sure that's what code calls for, especially for load-bearing walls, where double top plates have to overlap at the corners. --Keith :mrgreen:

I am new to all this building, but here (below) is what I just did. I had about the same angles as your talking about. My Bro in Law does Drywall professionally and stopped and said NOT to use paper tape on angles, but instead use a special plastic tape (not sure where he got it from) but thats what we used. Its very strong. My wall framing was out of 2X4's, but when I cut my angles at the header and floor boards to 45 degree angles, I then used a 2x6 to go across. It matched up nice with the cut surface area of the angle on the 2x4. Then ran the drywall right up against each other, used the plastic tape and it turned out perfect. (plus the plastic tape makes your angles and creases much nicer, tighter and straight). Here is a pic - http://www.johnlsayers.com/phpBB2/files/2a_652.jpg Again, I am new at this, but maybe this info will help ya. AJ[/url]

They make outside corner bead that will conform to the outside angles of your walls... goto the USG website and look for information there... hope this helps :wink: also Miter those 2x4s so you dont have that gap in your framing.. youll be able to get your layout much closer to the actuall center of your outside corners

There's a product called "Sure Corner". It's basically a corner bead, but flat like paper. It's paper backed, but has a metal strip in the middle and you just fold it to the corner in which you're applying it to. Works great, and I used it on a corner just like you've got.

Just did a quick google search. Here's a picture of the stuff... http://www.toolfetch.com/Category--Dryw ... 7-B0.shtml
