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

Easy to apply and worked well.

Does the job well. I had some large cracks in fire bricks and thought I'd give this a go rather than go to palaver of replacement. The product is easy to apply and adheres well. After a few burns, the colour blends in well enough for it not to be obvious. The fix has lasted well.

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.

This is good quality fire cement and lasts a long time

I purchased this to repair cracked and missing cement in my fireplace base. I've had several fires since and it's held perfectly. Happy with the result.

The Everbuild KOS Fire Cement works well and withstands high temperatures, but it’s very hard to apply and dries slowly. It’s a solid 3 stars.

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.
