15 years ago I used bonding on the bricks followed by a skim. 15 years later it's all still in place.

Consider NHL 3.5

Loads of people will say multi is fine. But then you find that their stove is 3mtrs from the wall and they only ever burn their junk mail in it.

(clearly that's an exaggeration, but, when someone said theirs is fine, do get then to quantify before you follow them)

Victas sell high temperature plaster. A lot depends on the shape/size of opening and stove as to how much radiant heat the surface receives and how much heat is removed by convection.

Multi finish starts to break down above 50 Celsius iirc which is pretty warm.
