I am completely re-doing my woodburner setup. when we bought the house, it had an insert that had been fitted into the existing fireplace. I tore all of that out so that i could put in a woodstove. I slapped a woodstove in there and that worked alright for a while but now im getting sick of looking at the unfinished floor under the stove. I am thinking that i want to use slate tile under the stove. i just finished putting up slate tile behind that stove and i love the way it looks. i would like to do the same for the floor. Has anyone done something similar to this? i am curious about the underlayment to use under the slate. Any insight into this process would be greatly appreciated! thanks all!
