Hi,
We had a leak in our roof 18 months ago and since then have had a new roof and the wall has dried out in our bedroom. I have scraped away all the old paint and some plaster and have used an eco friendly stainblock on the area which normally requires 2 coats, however every time i put it on the stain marks come through.
Has anyone got any suggestions? I need to finish painting this room asap and know the wall is completely dry.....
Thanks
Sally
