It might be possible to add another layer of concrete to the top of the crown to seal these cracks.
When the trusses contract the ceiling lifts and pulls up the crown molding creating separation gaps or cracks.
Cracks that appear where a ceiling intersects a wall may be due to truss uplift roof trusses tend to move a little when there is a seasonal change of temperature or humidity.
The root cause of the problem stems from the contraction or warping of ceiling trusses the beams that make up structural support of the roof of a house.
These fluctuations and changes may result in the trusses moving or shifting a little.
Well what s obviously happening is you have a lot of expansion and contraction differential expansion and contraction between the molding and the ceiling causing the cracking between crown molding and ceiling and walls.
