          This is good stuff. I used it to fix some small cracks in the fireplace. The only thing did not like is the package said it should dry 24 hours before curing. 36 hours before curing would have been better. It worked well and cured but there was one spot where it bubbled up.

            Rutland Fireplace Mortar worked exactly as advertised. I had significant gaps between my firebox and the brick facade. After first filling these gaps with expanding foam firestop, I applied the fireplace mortar to provide a permanent fire-rated seal. This was one DIY home improvement project that worked out exactly as planned.
