    Mojo12345, good evening.

    Can i suggest that you consider using some Cillit Bang, black mould and mildew remover before you over paint?

    Cheap spray to get, suggest you try it on a small area in an unobtrusive area first, if it works, and it should, try on other areas, allow to dry then go for your painting option.

    I suggest the use of spray first because that stuff has worked for me on water staining, makes the paints life easier with better results??

    Ken.

    Sorry KenGmac, but using bleach based products is unlikely to block water stains. Shallac or oil based paints will normally suffice. Shellac based paints will be over printable after 30 minutes, oil based, you have to wait until the next day.

    Have faced this problem several times myself. Just painted over the stains well overlapping at the edges with oil based undercoat. This can then be over painted with emulsion when dry. You could use other oil based paint rather than undercoat, but avoid gloss since the emulsion may not stick to it.
