Will I need to sand it before I emulsion it?The coving in my house has been painted with gloss paint and looks crap.?
Yes, you will need to sand it with a P120 grit abrasive paper first or the paint will slip around when you apply it and will not get a good grip onto the surface,. You're not vigorously rubbing down, just providing a key over the entire area.





It wouldn't be a bad idea to apply a coat of undercoat (for wood) first and then emulsion that.The coving in my house has been painted with gloss paint and looks crap.?
You might get away with a couple of coats of white matt emulsion to give you a base to start again.


It is a massive job to try to sand it down.





Matt emulsion will give you a similar base to undercoat and will be easier. I did it with one room where it had been done and it worked.


Use a small gloss roller to give it a good finish as well.
lightly sand with a fine paper just to key it!


i would advice using a vinyl matt not normal matt as this will crack and peel with time


i would use a primer first for good measure but that is a bit overkill for just a diy job
Looking at your answers..everyone seems to have missed using liquid sand (B%26amp;Q) works very well to provide a key for application of as many coats of emulsion paint as required..does exactly what it says on the tin
You will certainly need to make a 'key' for emulsion to stick. gently though - coving is only foam unless its the real thing.
Paint over it with satin paint. Not satin emulsion but the satin paint you can get for doors / skirting boards etc.
