Use this product in conjunction with fire bricks I’ll purchase from Amazon and saved over $2100 on having someone do the job. I did it myself minimal time and had excellent outcome.

Set quickly, only had instructions for mixing the whole container instead of mixing per part. Has held up well so far.

This is only the second brand of refractory mortar I have used but it was excellent. It was much better and easier to work with than the other brand I tried. I highly recommend this product.
