Black Fire Cement 1250 C - 310ml for Fireplace, Stove, Boilers etc

Was good and easy to use A ********

Superb grout which is soft and adheres well so allowing application in vertical joints and larger gaps. Used on open fireplace and soon dried to become firm and was rock solid when checked a day later (after coal fire had been on). Worth removing any excess earlier rather than later as it sets so hard

Great product hut a bit grey.Used this to seal up around wood burning stove where over the years the original had cracked and was getting caught on cloth and pulling out of the gapHas worked really well to produce very sturdy seal but over time and heating has greyed a lot, so it doesn't match the stove anymore , which is odd... the previous stuff had lasted over a decade with no colour change and kind if blended into the metal work, while this is clearly different . Doesn't look bad, just weird.Adhesive quality was/is excellent, it was easy to use and was great value for money, so i would buy again.. bit thought people should be aware

Best fire cement I have used on my wood burner, stays black and seals without cracking.

Used for tiles around my fireplace. Great worked well. I also used it as a grout. It’s grey once dried.

Work well very happy

Used this on two different fire flues. On one flue its good, stayed black hasn't crumbled. On the second fire its a different story. Its gone white and has started crumbling. Did them both on the same day so I don't know why its reacted different.

I actually needed a heat resistant black GROUT for a hearth (ie a horizontal surface). Problem is that no-one makes one - insipid sandy brown or grey is all that's available. I wondered whether the black fire cement might work - though fire cement often requires high temperature (900+ oC) to fully harden it.Firstly, to give some perspective, we're in Covid Pandemic Times! I contacted the company (that manufactures the various products) with a couple of questions about the company's HT tile adhesive and black fire cement's usefulness as a grout (see my other review), waited 5 days and received answers to (irrelevant) totally different questions! More perspective ... the questions you ask go to the Sales team; there's no way to ask the techy team a question and during this difficult time, the techy team may not have been available.I set up a couple for experiments of my own (I'm a chemist/scientist by genetics and training) and found that the cement could be used as grout - after a couple of hours with no excess heating - it fully set and even with hard rubbing with a damp cloth no black staining transferred! It's very easy to apply out of the tube, though quite runny (not a problem on a horizontal surface).However, after a few days the cement turned white! A quick rub with a damp cloth changed it back to black ... after a handful of repeats (hoping that whatever was leaching through would finally be gone I used an indelible black felt tip to stain the cement; It's still black after several months - problem solvedEDIT: the 'indelible' black pen ( made for paper etc) fades somewhat after several months of being heated by the coal fire!! - It only takes a few seconds to reapply so on balance I am very happy with the cement.
