I'm planning to put a free-standing wood burner into a house and I wondered if I needed to use any special fire-retardant paint on the wall behind the burner? Its a solid brick wall with plaster and flues will be exposed before they go into a chimney on the upstairs floor all lined etc so we are all fire-proof with the materials. These modern stoves don't give much heat off the flues but it is the area behind the fire I am wondering about. I did plan to put some tiles but with budget pressures I wondered if I could get away with just painting the wall? Any advice out there? Thanks
