Have just had some roof repairs to a leak which had resulted in water running down the chimney breast ending up on an inside wall. The wall has now dried out but will not take emulsion paint without ending up with a brown stain where the leaks were. In an effort to seal the (now) bare plaster I gave a coat of wallpaper paste prior to emulsion but this has not worked and the emulsion coats are starting to peel off. I intend to strip off the emulsion where necessary and use some sort of seal prior to re-doing.
Would be most grateful as to what I need to use for the job.
