We have rounded outside corners throughout our house what is the best approach to installing crown cornice molding?

The baseboards that are currently installed just come to a 90˚ point and the gap is filled in with putty, trim paint, mud, or combination thereof.

Any suggestions for a finely finished look to go with the rounded corners?

  • I've never used it -- I prefer the angled look like in Doresoom's answer below -- but have you looked into flexible crown molding.

You can add a center section at the corner that runs at a 45° angle to either wall. That cuts down on any gap you might have, but makes the installation and cutting a bit more difficult. My house has a few faux pillars that use this technique:

(I know, I know, I haven't gotten around to touch ups after we painted the walls...)

And here's a lookup table for cutting crown molding (source):

    Keep in mind that the chart is useless if you assume that corners are 90 degrees. You've got to accurately measure. Oct 1, 2013 at 13:41
