How to Install Crown on an Uneven Ceiling
Crown molding is a type of trim that goes around the tops of your walls, to span the joint between the wall and the ceiling. The idea is to give that joint a nice clean look. However, if your ceiling is wavy and uneven, then the wood trim will not sit flat against it. One solution is to redo your ceiling. A much simpler solution is to simply caulk the trim along the top of the crown molding, so that the gaps are sealed and hidden. Does this Spark an idea?

1
Take the measurement of the first wall from the first inside corner out to the end. Transfer that measurement to a piece of crown molding, setting two marks on the piece with the measurement between them. There should be four to five inches of molding beyond each of the marks.
-
2
Lay the crown molding on the miter saw positioned backward and upside-down from the way it will be on the ceiling. For example, trim that is starting on the left side of the inside corner should be positioned on the right side of the saw blade. The face of the molding, which will be facing down from the ceiling, should be facing up from the saw platform.

Swivel the saw blade to point 45 degrees inward, toward the middle of the length of molding. Make the cut.

4
Move the trim so the opposite end is under the blade. Turn the blade 45 degrees inward again, so it's in the opposite direction as it was before. Cut it.

5
Set the molding in place along the top of the wall, against the ceiling. Set your level under the trim, and get it as level as you can while trying to minimize the gaps that will appear between the trim and the uneven ceiling. Secure it to the wall with your finish nailer, shooting the nails in pairs every 12 to 18 inches.

Measure and cut the remaining pieces of trim in the same manner. If any of the pieces are meeting at outside corners instead of inside corners, then angle the 45-degree cuts outward rather than inward. Nail each of the pieces in place in the same manner as the first one, with the mitered ends butting to each other.

Run thin, even beads of caulk along the molding where it meets the ceiling, closing off the gaps.
