Wainscoting techniques for a rounded outside corner
What is the best practice for wrapping wainscoting around a standard rounded drywall corner?
I could make the wainscoting corner 90 degrees and put on a piece of outside corner trim. I worry about the look with a rounded drywall corner above, and the appearance of looking “cheap”.
Alternatively, I could do a multipiece corner to take the angle in stages ala baseboard trim, but the wall is not exactly plumb and it has a little motion as the corner is 5″ from the strike of a door (this is a basement wall that is floated from the ceiling for expansive soil conditions). I worry about the joint appearance, trimming the outside edges (do they make 120 degree corner trim?), and shock from the door shaking the joints loose. Mitigating the door concern is that it is for the utility closet, so it will not be used often.
The wainscoting is HD’s stock 7″ vinyl panels and stock mdf pre-rabbeted base and chair rail. It will be a playroom for their kids eventually, so they like the maintenance free aspect of the vinyl. Drywall has knockdown texture if it makes any difference.
Does anyone have a good idea or best practice on how to handle this?
Thanks in advance.

Is the wallbd. finished?
If not, or you can afford a change in bead, there's a transition to square corner bead that you could apply to make for a more usual and easy corner detail.
It is already finished
They made the change after the drywall was done and textured.
When you say transition, do you mean change the whole bead or there is a transition piece that will allow square and rounded on the same corner?
Thanks!

And look for Bullnose beads. Then a ways down is :
#0917 - 3/4" R. Bullnose Adapter
Joins a 3/4" Bullnose Outside Corner and transitions to a square bottom corner for simple installation of the baseboard.
Changes Bullnose corner to square corner-Nicely. In your case there'd be some mudding at this new transition. And the resulting new texture/paint.
Never used the vinyl stuff, but have used the beaded pine t&g from HD and simply routed the outside corners with great success. Not sure if this would be an option for the vinyl (i.e. if there is enough depth)? Maybe test a mockup corner. You will have to "pack out" or fur the rounded corner to form a 90 deg. edge.
Not quite sure I understand
Do you pack the backing for the corner with pine and then rout the whole assembly with a roundover bit?
Thanks!
I was thinking you could create a 90 deg corner, butt the wainscot like a regular 90 then hit it with a router. You would not be following the profile of the rounded wall corner. Not sure if this is the look you want, but I don't think it would detract from the look of the room. You would have to add some type of filler to the chair rail cap though, and that might be a problem with vinyl.
Maybe you need to talk to the same people who make the rubber trim for arched windows.
Could you kerf cut the back and bend it around the corner?
I might have to look into that
How would you do the base and chair rail trim? Instead of 3 pieces go to 4 or 5?
Thanks!
