1st time poster here. I live in Albuquerque.
I'm installing solid oak crown moulding in our LR. This is a 60 year old house with plaster walls/ceiling and cinder block outside walls. I've dry cut most of the moulding: corners and joints look very nice.
I glued a furring strip at joint of wall and ceiling around entire perimeter to secure the moulding: using 2-3.5 in finishing nails (inserting them by hand: no pneumatic nailer). The problem: the ceiling height varies by as much as 1 inch, leaving large gaps between top of moulding and and ceiling in many places. This has left me with 2 challenges, suggestions for which is why I'm posting:
1) I'm not satisfied with how secure the molding is on top. Measured horizontally from the wall to outer surface of the moulding where it meets the ceiling is about 2 1/4 in. I would like to use a finishing nail on the top lip of the moulding into the top of the wall. Nailing a finishing nail directly into the wall about 1/2 below the ceiling, I found it must go into the wall at least 2 inches before it grabs well. Thus, I'm trying to find a finishing nail long enough: at least 4.5 inches. Longest I can find is 3.5.
I found one on Google this morning here:
emailed them and am awaiting a response for availability.
I'd like to avoid using screws, as counter sink/fill would most certainly detract from the appearance, but this will probably be my solution if I can't find finishing nails I describe.
2) Some of gaps I describe on top of moulding between ceiling I can caulk, but some are just too large. I'm contemplating floating the ceiling in the larger gap areas with layers of drywall mud. Wondering if anyone has better suggestions however, and an inch thick area filled with this material makes me a little nervous about cracking over time.
Can take some photos and post them if this will help anyone conceptualize what I describe.
