heat resistant plaster

[harvey2012]

do i need to use heat resistant plaster on a wall behind a log burning fire, it's been boarded with fire board, can i get away with regular gypsum plaster?

i do not think that gypsum plaster will last very long. i have used fireboard and tiled direct onto the board without a problem. but a log burner can throw out a lot of heat so a heat resistant plaster would be a better option..

Yep seen a fibreboard fail in no time float with sand, cement and lime and rub up to a smooth finish.

you cant use gypsum, well you can, but it wont last very long. if you used fireline that doesnt meet regs. have a gander at this for some diy stuff
