What is the coving made of? A lot of mine is polystyrene, and in one
room there had been a water leak leaving a brownish hue. it was a
difficult thing to cover. As you say many coats of emulsion did, in
the end fix it. Hopefully its not come back I'd never know!

It is not polystyrene - Plaster sections. I have polystyrene in another
room - I think the builder "forgot" to do it - so I did .
