Flashing / Halo on white ceiling.

[46philh]

Painted the ceiling with white Johnston coverplus and I have section which has Flashing / Halo effect. I used an emulsion brush on the edge and must have dried before I got to it with the roller ?

Can I roller over it now with a small roller or do I need to do the whole ceiling again?

It is a large 5m by 4m high vaulted ceiling with roof lights so not the quickest ceiling to repaint.

painted it all again but still get slight mark halo effect. Not sure why might maybe it is just a shadow above a window. Can hardly see it so will stay as it is.
