Bowed Ceiling Crown: Install or Return?


Question:

I'm installing new ceiling crown in a room that is 13' 6" x 11' 1". The walls and ceilings are fairly straight. The old crown (most likely 40+ years old) started to reveal cracks/separate from the wall and ceiling in a few places and was removed. The new crown is a single piece, pine crown (4 x 1/4" wide with a 38-degree spring angle) with ripped 2 x 4s being installed for a wedge/backing board so I can nail anywhere I want to hopefully eliminate any movement large enough to cause cracks to appear. Each of the 4 pieces of new crown is long enough to cover the entire length of each wall, ie, no scarf joints are needed.


The issue is one of my 4 pieces of new crown (yet to be installed) is noticeably bowed. This one piece of crown is a "smile", ie, both ends are higher than the middle (the middle sags lower). Is there some trick to pulling the bowed/warped ends downward? Do you just muscle it into position? I have popcorn textured ceilings (yes, I actually like them) and don't want the non-working end (the ceiling crown end I nail into position last) to be banging into the ceiling destroying the texture while I nail the crown into place. For strength and aesthetics I also would prefer to not cut the bowed piece into multiple pieces and do a scarf joint(s).

The town I live in is pretty small and I may have bought the last paint-grade, 4 1/4" crown in this particular style in the entire city so getting more crown might be possible but it will be a bit of a hassle.

So...is this workable or should I avoid the hassle and just get a new piece?

Perhaps tack it to a straight 2x4 or something that you can pull off after it is up???

Test the trim to see how much it bends. Push the trim against the floor. If it bends easily, you can use it. If it doesn't bend easily, it is damaged.

At first I thought your ceiling was bowed instead of the new crown. If I were installing the molding, I would put that piece up first then the one on the opposite wall and pop the other two pieces into those. A stick of trim that long will work without much notice of a bow in it.

I have seen that before and have used a screw or two to pull into place, countersink and fill.
Good luck!

All -

Thanks for the advice. I especially thought using a tacked-up 2x4 and/or finish screws to hold the trim in place were good tips. The good news, though, is that most of the bow has disappeared.

How?

A major change in temperature in the room where the trim is temporarily sitting. It wasn't bowed all that bad when I bought the trim. Then just before starting this thread I saw a huge bow (total linear change of 5"-6" over the length of the 14' piece of trim) and I about had a heart attack. Muuuuuch less than that now; maybe 1"-2" bow in it now; definitely workable.

Still, thanks for all your sound advice!

If you can get it up in the air so a moisture content can get back to center.

A chain is only as strong...

Never let the lot guy select your wood for you...

You see pro's at lumber yards hand selecting framing materials for their jobs so that the rest of the build will be easier. (granted a house shows up as a strapped pallet - but the good carpenter throws the nasty stuff aside)

Or uses it for blocking, etc.
