I have recently had my kitchen plastered and when it dried out it has identified a leak in the central heating system in the loft above. I have fixed this but after a week of dripping it has left a rusty ring marks on the ceiling.
Question is, before I emulsion the ceiling is there any kind of sealant that I need to apply first. Guessing something will show through if I don't.
