Crown Moulding Over Tile

[crokett]

I think there was a thread on this recently but I couldn't find it. I remember not liking the idea of gluing the moulding up. It might have been Woodnet. Anyhoo, I finished tiling to the ceiling on the new bath. Originally my wife didn't want the crown up. If she had, I'd have put a nailer strip up and just tiled to the nailer. She changed her mind and wants the crown. So two questions, how to install the crown over the tile? What is the best way to transition to the crown that is not installed over the tile? It will be installed flush to the sheetrock so what is over the tile will sit proud of what is over the sheetrock.

Instead of a nail strip on the wall, could you do one on the ceiling? Would be a little more difficult in places (lack of joists, etc), but it might help a little.

I would just put a spacer the thickness of the tile on the sheetrock, or the crown (whichever is easier). That type of fix isn't too noticeable.

The way the joists run, not unless I used hollow-wall anchors. I may just drill through the tile and put anchors in. It will take a while but is probably the best solution. My other thought was gluing the backer to the ceiling, but I am not a big fan of something like that if I ever wanted/needed to remove the crown.

if she is adamant about crown thru the shower area and if you have some tile left, measure to where your crown will sit and remove the tile above that line, including the full tile that sits at that line. If you get to save any tile you can cut those to fit after you've run the crown. That way you dont have any issues with attaching the crown. Sometimes you have to make a mess before you can clean up!

I forgot to address installing crown on tile. You would need a backer strip made on the spring angle (angle the crown protrudes from the wall) of the crown. I make those by ripping 2x4's on the angle. Allow a small gap between the face of the backer and the back of the crown.

I would steer away from mounting it to the ceiling. I've tried that and got poor to bad results. It needs to be fixed to the back wall (on the tile). I would use Liquid Nail or Polyseamseal to adhere the backer to the tile. Worst case scenario, it could be epoxied, but that would be harder to remove if it ever had to be taken off.
