Hi everyone, hope this is the right forum for this question.
We're shortly going to be having a log burner installed. I've opened up the fireplace to the original builders opening but in doing so I had to rebuild the sides (are they called cheeks?) of the opening as they'd been damaged by previous fire/boiler installers.
I was intending on having the inside of the fireplace rendered but now, for various reasons, we've decided on just keeping the bricks exposed.
I'm going to clean up the bricks at the back of the fireplace and repoint then but I've read that you may need a high temperature mortar or lime mixed in to resist the temperatures.
But I didn't use high temp stuff when rebuilding the cheeks, just a regular mortar with plenty of plasticiser.
Do I need to take out the new mortar and replace it with high temp/lime stuff or will regular mortar hold up under the heat do you think?
Thanks for any advice.
