I had quite a few Artex ceilings replastered in my home. Everything is fine except one large room. I had noticed that there was a crack in the Artex running the length of the room down the middle and hoped the new plaster would hide it but it has reappeared in the new plaster and now I have painted it white it is noticeable. (At least to me it is!)
It is a very fine crack. The room is sound - I do not suspect any structural problems.
What is the best way to hide the crack? Should I keep painting white matt paint on top to 'fill' it? Or will it keep reappearing? What 'caulking' stuff can I use?
If I wallpapered the ceiling would that 'hide' it or would it still reppear again?
