[This is part of Our Kitchen Molding Makeover series.]

This is the simplest piece of molding to install out the three pieces that make up our crown molding buildup.  This won’t take long to install.

Above  I’m starting in a left corner and then working to the right.  I want to get the cornice wrapped around the air vents before I run out of energy for the day.

Note  I forgot to mention that I created my cornice layout lines by removing the lower detail on my crown molding model, and then held it up in place and scribed the ceiling.  I made a video of how I do the layout, and then accidentally deleted it.  Sorry.

I’m starting on the left and then working right.

Making the Piece That Wraps Around the Vent

Ceilings are usually wonky above these air vents, so it’s best to assemble the pieces of the wrap on a bench and then install it as one unit.

I should have used my Elmers wood glue instead of Liquid Nails.

Hold it in place long enough for the glue to set.

Now you can keep working your way around the room until the rest of the cornice is installed.

I used Liquid Nails for Molding and Paneling on the cornice.

Below  When there is a slight bow in the ceiling like there is below, try not to nail so that you force the cornice into the bend, which will make the cornice look warped when finished.  Rather, leave the cornice as flat as possible and then back-fill the gap.

A gap this large I usually fill with spackling so that I can shape it to fit the cornice.

If you have any energy left after installing the cornice, then let’s get started installing the ogee crown molding profile.

Oh, if you need me to clarify anything, I’ll answer any questions you might have in the comment section below.
