:coffe: I was on a job recently and chaps installing a log burner finished the alcove with universal one coat claiming it has sufficient heat resistance to prevent cracking. New one on me, they said they do it all the time.
Any validity to this claim do you think? If so it would save an awful lot of flaff

It's still gypsum based so I can't see how it would be heat resistant.
 
Hi guys, new to forum, been asked to plaster inside fireplace By family membe, not usually my thing! It’s been boarded with standard gypsum board, log burner to be fitted. Question is, what product to use, noted comments on vitcas, appreciate any pointers. Cheers.

Very true, I’m hetas I usually board with cement board, whatever I can get my hands on but at least 12.5mm not the thin 6mm stuff then pva and skim with board, as long as you meet the manufacturers minimum distance around the fire the heat shouldn’t crack the plaster. Out of well over 100 stoves iv had 1 crack on the back, I scraped off and reskim with render mesh bedded in, never had a problem since
