Simply does what it was advertised to do!

Would Recommend

Simply does what it was advertised and spec'd that it would do. Used to seal around a natural gas line entering into fireplace. Color "almost" matches the color of the firebrick. Three fires and no cracking around sealed area. Will use again on high temp applications.

Fireproof Sealant

First time I used this product, I was a little hesitant about it. Once I used and it dried it created a nice seal.
