Everbuild KOS Fire Cement Cartridge – Ready to Use – Resistant to Temperatures Up To 1250˚C – Black – 500g

I needed this fire cement to reseal my daughters cast iron fire surround. The surround had come away from the wall a little and was leaking from the indside, after cleaning the affected area and using a wet sponge to moisten the area I applied the cement as instructed on the tub. It did a perfect job of making a smoke proof seal and once a fire had been set the cement cured to make a permanent fix.This did exactly what I needed and was good value, the instructions are easy to follow, I noticed that the tub had been shrink wrapped to avoid any mishaps during shipping, a nice touch.

This is better and a lot easier to use than I thought it would be. You do need some muscle power to spread it but once done sets perfectly. Been a while and still happy

I was a little suspicious that a product at such a low price would be any good. I was wrong. This fire cement is great. It has stayed blacker than the one my chimney sweep uses and hasn't cracked at all. I did make sure I prepared and cleaned the fire and flue well first but I didn't make too much effort to really get a perfect finish, yet it looks pretty good! It is a little coarser than cements I have used before but I am sure you could get a really smooth neat finish if you need it. Job done quickly and effectively at minimal cost and plenty left for future jobs. Fast efficiant delivery too.

Although it’s very gooey and application is a bit difficult, it is by far the best fire cement I have used. Used this around my fireplace after having to replace “professional work” and it was amazing.

Repaired cracked fire brick coal and wood fire, easy to use and works well. Recommended

Does what you want it to do

easy to use and works very well.

I was initially pleased with this fire cement as it sealed my leaking fireplace well, stopping smoke from entering the room as soon as it hardened.Sadly though, the good news didn't last long. The cement continued to harden to such an extent that cracks appeared after about a week allowing smoke to enter the room again. Eventually, after about 3 weeks it turned to dust. Needless to say, I repaired the fireplace with a fire cement of a higher quality.My advice is to avoid this product.
