Making progress with the opened up fire place, but what do I seal around the edge with? This is the gap (about an inch) between the back of the plaster board, and the bricks/granite blocks behind.
a) Plaster?
b) Heat resistant plaster?
c) Heatproof screed?
d) Cement/mortar?
e) Something else?
Thanks!
Plaster or mortar no probs. IME with a solid fuel stove, both render and plaster can stand the heat. I whitewashed the inside area though as I reckoned that emulsion would not survive.
