Brush marks on coving difficult to remove

[John123456]

I've recently moved into a house where the previous owner has painted all of the coving with vinyl silk emulsion. They have used a brush rather than a roller which has left some very pronounced brush marks. I've sanding the coving down and applied matt emulsion with a gloss roller but as it dries bits of the previous paint raise up to give a pretty awful look? If I sand down and paint 4 or 5 times I finally get an acceptable finish but the time that it is taking is ridiculous. Does anyone have any suggestions on how to solve this problem more effectively. I've thought about maybe painting a few coats of gloss undercoat to act a a sealer and a filler/primer.

I'd love to know how you are painting coving with a roller. A complete waste of time and effort in my opinion. You are better off using a brush, especially as you need to cut in the top and bottom edges which cannot be achieved with a roller.

Sand it flat if necessary and paint with a decent brush, about 2" should give an acceptable finish.

Hmm, sanding coving, most coving is made of plaster or plasterboard like material or if really cheap polystyrene, which won't take kindly to aggressive sanding. Try a light sanding and paint the new emulsion on with a synthetic bristle paint brush.
