Installing Crown Moulding on Frameless Cabinets

Tips and tricks for attaching crown molding to the top of frameless cabinets. March 26, 2010

Question
I'm trying to figure out best way to prep cabinets for crown molding. I have being doing it by installing cabinets, then attaching blocking flush with front edge, then attaching finished trim with angled blocking (to support crown) and then the crown. It seems to take too long and although it works, I do have to secure blocking through cabinets, requiring covering holes etc. What do you guys do or suggest? This is for frameless cabinetry. Thanks for your help and suggestions.

I just installed crown on a painted cabinet job. The finish was real nice, so I didn't want to shoot any holes in it. I also had a 14" run and couldn't get the crown that long. What I ended up doing was gluing and pocket screwing the crown to some 1/2" MDF. I let it hang over the bottom of the MDF 1/4" to cover the top edge of the boxes. I pre-cope my inside corner, then assembled my outside corner and attached it to MDF as well. Then I sanded up my splice and my outside corner and sprayed it. I got it onsite, placed the assembled units on top of the cabinets and screwed it down from the top. Slickest way I've ever done it. Of course it only works if you aren't going to the ceiling.

Running crown at the top of frameless cabinets when they go to the ceiling has always been a challenge since ceilings go up and down and the doors under the crown go in a straight line.

I put on a flat apron piece the length of the upper cabinets flush with their top edge, shooting it on with nails at the top edge where the crown will cover the nail holes when it is added. The apron can be anywhere from 2 to 12 inches wide depending on circumstances. It also brings the crown out to a starting point on the cabinet face nearly flush with the face of the doors, which looks way better than back at the depth of the cabinet boxes only.
