Plaster type for fireplace

[hi1]

Having just removed a 70's brick fire surround, by order, the wall is going to need replastering. There will be a woodburner quite close to this plastered surface. What type of plaster is most heat resistant and suitable for this? Would you build up with a cement render then skim on top of this? Brick work is pitted not a smooth surface. Its not far off 10mm to bring the surfaces level.
There is now an edge where the old plaster met the surround this edge is squareish to the brick work underneath, is this the best edge to plaster to or do plasterers prefer a tapered edge, which gives the best finish and is less likely to shrink/crack

This type of question has cropped up a lot lately, especially regarding "plastering" around wood burning stoves.....Normal gypsum plasters are not suitable due to the high temperatures, and crack etc over time, with the heat given out by the stoves,,,,, and lime render, although suitable, might not blend in with the "smooth" finished look of the surrounding walls......This "plaster" looks perfect for the job...Just found out about it today from a company in Devon, after making some enquiries... got a very helpful reply..Check out the info at: www.envirograf.com/acrobat/115.pdf If I also may be allowed to include the phone number, it's,, "Envirograf", on: 01304 842555. This plaster may also be of interest for future reference, to the regular contributors to this Forum.
