Hardwall on Chimney Breasts?


New Member
Hi Everyone,

Our plasterer has used Hardwall on a chimney breast in an attic room. Does that sound about right? I have read conflicting view on using it in damp places. Clearly the chimney isn't exactly the driest of places, and being up in the attic means it is closest to the chimney pot etc...

What is the worst that could happen with Hardwall? Assuming the damp just affects the bond?
