Outside Radius Corners for Crown Moulding
Here's a handful of cool ways to deal with bullnose wall corners when installing crown moulding. November 14, 2011
Question
What do you do when installing crown in a house that has radius outside corners? Thought of corner blocks to butt the crown into, but can't find any with the radius.

From contributor R:
If you're talking about bullnose corners, cut 2 - 22 1/2 degree outside corners around bullnose. Void behind will be miniscule. Do it all the time; base done the same way.
From contributor J:
Any good wood turner could make up these crown corners (four at a time) just like the baseboard corners and do it much easier then the best plaster-pull process.
From Gary Katz, forum technical advisor:
I'm with contributor R on that one. Crown looks nice when it breaks at an outside corner - that's where you really get good shadows and light across the profile. A two-piece outside corner adds a little more drama and fits into some homes very well, especially with bullnose drywall corners. You can get turned round corners, or even flex-trim round corners, but they don't have the same impact - they don't emphasize the shape of the profile because they don't break at an outside miter. We've always filled the little space with caulking. At one time, there was a company that made these cool little chamfered filler pieces which tapered down to a point - they had to be installed during drywall taping, at the lower edge of the crown. They looked very cool... but filling the small gap isn't even noticeable.
From contributor M:
I am with Gary. I hate 22-1/2 corners on a nice bold crown - cheapens the whole look. The best thing they came up with was the transitioning corner bead from radius to square.
The plaster corner was impressive but not practical.

Here are some we made last year.
