    We had a bad roof (well chimney pointing) leak which stained a lime plastered wall in our old farm cottage. We don't want to put anything oil based on it but emulsion's not doing anything to cover it up. Any ideas other than replastering?!

    Try a stain blocker. Loads of em on the market. I use a solvent spray by zinseer, dries in 10 mins, leaves a matt finish ready for going over with emulsion.

    Zinsser BIN is white tinted shellac suspended in alcohol.

    Alcohol! What's not to like?

    In all seriousness it is a great product, albeit pricey. Clean brushes or mini rollers in household ammonia, or use the spray version recommended by RossoTrade.

    It will smell of alcohol for about 30 minutes until it dries.

    It can be tinted with universal tints by a decent decorator's merchant if you want to cover the whole wall.
