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

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

Good for gas fire surrounds.

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

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.

Easy to use (with a sealant cartridge gun (not supplied)) and dries fast. The only issue I have, and this is not the fault of the manufacturer, is that the gun and cement are impossible to manoeuvre in a confined space, i.e. at the back of my woodburner's top flue. I overcame this by spreading the cement using a gloved wet finger, but it would have been better if I could have laid a proper bead. Perhaps there's a market for a smaller size which doesn't require a cartridge gun. In any case, this did the job well and blended in nicely with the woodburner and flue pipe. One of the great things about this is it can be used before you light the stove. The heat will dry it out and help it to cure quicker. The other issue with this is closing the cartridge after use. I solved this by inverting the cut off end and pushing into the open tube.

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

Good to start with but heat cracks it after a while so need to keep replacing

Used to repair a smashed clay chiminea lid. Reassembled like a jigsaw, the fire cement sucessfully jointed the pieces.

Cumple con lo anunciado. Buen producto. Lo he utilizado para sellar el tubo chimenea de una estufa de leña y no se escapa nada de humo. Es fácil de usar.

Utilisé pour recoller les parois intérieures en matériau réfractaire d'un poêle à bois. Réparation effectuée sans problème. Pour l'instant tient parfaitement à la flamme.

Wie beschrieben

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
