Everbuild KOS Fire Cement Cartridge – Ready to Use – Resistant to Temperatures Up To 1250˚C – Buff – 1kg

Good product easy to use.

I have used this to refit a metal chimney to our chimenea which had broken due to rust and also filled in some cracks in my wood burner firebricks. It fixed the chimenea a treat. it is pretty thick to apply and I ended up making a rolled sausage out of the cement, applying it round the join and smoothing it using a spatula and a little water after refitting the chimney. This worked very well and after it had dried a little while I lit the chimenea and the fire cement did indeed set rock hard. The firebricks were a little less successful, it works fine for larger cracks where you can get a decent amount of material in and less well for thin cracks. Good product though, does exactly what it should and not expensive in my opinion.

Used this to put loose coping stones back on. Did a great job and they are nice and secure. Thank you.

patched up worn vermiculite stove fire bricks that were wearing thin and crumbling at the bottom, made the bricks as good as new, saves replacing the set for another while. I left a day to cure, then only a tiny fire for a few hours to gently dry it, then has been fully fired and so far so good. Easy to apply with a paint scraper and much cheaper than a new set of bricks, though I have a spare set in stock for when resurfacing/patching is not feasible.

Easy to use & does the job very well.

Used to fix chimney crack seemed to work well, easy to use and set good. Stopped any water getting in and braking it more
