Hi, I have recently knocked out all the very old render from within the fireplace to reveal the lovely original brickwork, however most of the mortar between the bricks is very brittle so I was going to remove this too (about 10-15mm depth) so that I can re point them up. I was just wondering what kind of mortar/mix I would need to use as I am going to be getting a multi fuel stove installed, therefore it will be extremely hot around this area and I wouldn't want to mortar to crack/break etc.
Any advise would be extremely welcome
Thanks in advance!
