Sealing old chimney breast
Having just removed a modern false chimney breast I've discovered the
probable reason for putting it in in the first place. Namely, the original chimney breast is heavily stained with wood and coal tar which has worked it's way through the brickwork. I solved the underlying problem about ten years ago by installing a multi-fuel stove with a nice thick stainless steel chimney liner which goes right to the top of the chimney but what is the best way of sealing the stained plaster so I can paint the chimney breast without worrying that the stain will come through ? I'm currently considering that good old staple, PVA. Would a nice thick coat of that be sufficient or do I need something more substantial ? Cheers, John |

Cheers, John It is possible to use PVA although you can also buy a dedicated masonary sealer (one i used was by Feb). Failing that, I have had good results in this situation with a regular good quality oil based undercoat paint. HTH Rob |

I've never used it on smoke/tar stains like you have, but it's certainly worked well for me with other stains David |
