search the forum, seriously, for a lot of discussion on the subject... upshot is, the only viable safe bet is 'vitcas' (google it) plaster... failing that, eml will expand (and consequently crack the plaster), but a limey mix will help

I just used dri-coat and multi round mine, and a bit off wallcrete over some board on gypframe, looks mint and not a murmer

use high allumina cement from kernoes its a refractory cement made to withstand temperatures above 350c its used in pizza ovens and blast furnaces. mix at 4-1 with sand scratch 5-1 top add waterproofer or plasticizer as normal Kerneos - Aluminate Technologies - Our offer at the heart of your formulations ring for your nearest supplier,

Before you install the expament, cover the area with a few layers of tin foil. This will help deflect the heat away from your render

All what has been said above is good just leave the expamet out it will expand at a different rate than the render and crack it, well thats what the experts say anyway.
