I'm still looking at ways to fill the gap between my artex ceiling and my wall - I have had several suggestions but now I am thinking about putting up some lightweight polystyrene coving. The only problem is that I have an artex ceiling (with a one-inch smooth edge around it). The artex on my ceiling is in a circular pattern (put up before I moved in). If I used some narrow coving (smallest width available), does anybody know if it is possible to do? Also, what sort of adhesive would I use to secure the coving to the ceiling? Thank you.
