hi, hoping someone can help, i've plastered the front of the fireplace but now need to do the inside. Its a small opening, current rendered over brick but i intend putting a log burner into the fireplace. I wondered if anyone can tell me what i need to put inside the fireplace so a log burner can be installed. i assume normal plaster would crack due to heat, someone mentioned ready mix fire cement? Any ideas please? ultimately i want to paint the inside of the fireplace.
(apologies if i've posted in the wrong forum area)
