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

This stuff is really good, works very well on my cast iron fireplace.

Easy to use, dried quite quickly but made a good job

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 gap Has 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

Used it on my cracked open fire back, so easy to apply, wear plastic gloves. Only used a fraction of the tube!

Good stuff ,used on stove flue , job done

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 solved EDIT: 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.

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

Did a good job of fixing a crack in fire brick for my multi fuel fire

Ce produit est facile à appliquer grace à son conditionnement en cartouches. Le mastic est relativement fluide mais il adhère parfaitement. Je l'ai testé sur du métal et sur du béton et dans les deux cas, aucun problème d'adhérence, ça prend bien et ça ne retombe pas lors de l'application. Ce n'est pas très facile à lisser, inutile de tenter de le faire avec du liquide vaisselle car en fait ce n'est pas un mastic mais plutot une sorte de mortier pret à l'emploi. Une fois sec le produit ressemble d'ailleurs à du béton sec. C'est résistant et ça parait fiable. Lors de son application, le produit est noir profond mais il s'éclaircit en séchant. Je recommande ce produit pour sa facilité d'emploi et pour son bon rapport qualité-prix. En résumé, Les plus: ✅️ facile à utiliser ✅️ réparations efficace à bas prix ✅️ adhère bien lors de la pose ✅️ dur comme du béton une fois sec ✅️ s'utilise dans toutes les positions, ne retombe pas ✅️ excellente étanchéité ✅️ très bon rapport qualité-prix Les moins: ❌️ lissage difficile, finition grossière ❌️ ce n'est pas vraiment un mastic mais plutot une sorte de mortier noir

War mir nicht sicher ob das Zeugs hält. Die losen Schamottsteine nach Anleitung mit dem Zement aus der Tube verklebt. Hält seit mehreren Wochen bombenfest, Ist zudem auch sehr gut zu Verarbeiten.

Tengo una chimenea de ladrillo refractario ya bastante ntigua y llena de grietas porque el ladrillo se ha ido rompiedo. Voy a cambiarla este verano porque los ladrillo ya se empiezan a vaer y no da para más. Probé este cemento para chimeneas y la verdad es que he podido sellar las juntas y el producto resiste perfectamente el contacto directo con el fuego durante horas. Tengo claro que cualquier rotura en cualquier elemento de chimenea o caldera, se puede reparar decentemente con este producto, que como digo, aguanta solidamente el fuego directo. Pero ojo, no es elástico, no es solicona o poliuretano, por lo que sirbe para elementos rígidos, que entiendo que son todos los que están en contacto directo con el fuego o en zonas muy calientes. Lo recomiendo

Hel OK för korstensrör.

Ho letto molte recensioni negative a riguardo, ma dopo averlo usato per sigillare i dischi di una stufa di ghisa devo dire che è ottimo. Probabilmente i problemi riscontrati da molti sono conseguenza di una cattiva applicazione: sulla confezione è riportato chiaramente che prima vanno bagnate le superfici da accoppiare, e che per completare l'essicazione va riscaldato (loro consigliano di farlo progressivamente nell'arco di 4 ore, io ho aspettato 2 ore e poi ho accesso la stufa lentamente lasciandola calda per qualche altra ora). In seguito al primo test possono verificarsi delle crepe molto sottili nei punti più spessi, che però basta rattoppare con altro prodotto quantomeno per il discorso estetico, perché funzionalmente non cambia nulla. Asciugatura lenta, c'è come minimo mezz'ora di tempo prima che inizi ad indurire. Me ne è bastata mezza cartuccia per il lavoro in foto
