How should I finish my chimneybreast?

[paddypower]

I have uncovered an old uneven chimneybreast whilst renovating. There will be a log-burning stove exhausting into the c/b. I was thinking of dot & dab fire grade plasterboard onto the bricks and some bonding (bonding used to level the face of the c/b).

Will the adhesive withstand the temperature expansion.? Should I use mechanical fixing as well and if so what? Will skim coat plaster stand the local heat of the stoves flue pipe as it passing through the plasterboard? Have I any other options? I cannot add a facing skin of brick, as this is a first floor room.

i would have thought most gypsum based plaster products have a fairly high temperature tolerance, although any severe differences in temperature can be damaging to any product.

a sand/cement/lime based render is usually quite effective in chimney scenarios.
