Everywhere I look at this chimney project there are more questions.
Where the fireplace opening meets the chimney above there is a lot of old tar burnt onto the concrete and brick.
I would like to stabilise the whole thing, to stop little bits of mortar falling off, and preferably paint the whole thing as well.
The first problem is the tar - can I clean it off? Can I paint over it without the paint just peeling off?
Cheers
