XL Fire Cement – Ready Mixed – Resistant to Temperatures Up to 1250˚C – Buff – 5kg

This is the 2nd one I bought so highly recommend There is very little mess as it’s already mixed so very easy to use, I must add that you do need to wet the surface first and add a very small amount of water when using. Colour is great and the container is airtight so if you don’t use it all at once you can keep it remaining aside. It’s so durable, I have used my fire place several times since using this product so I highly recommend

Really good quality & very good price compared with what can be obtained locally. Like others the tub was burst on arrival but had been wrapped by Royal mail in a polythene bag which stopped any drying of the material. Good service both by the supplier & Royal mail.

I've bought lots of this stuff (eight or ten large pots). I'm building a fire pit in the garden so I've used it for the fire bricks to ensure it's up to the temperature. Rather that being like mortar it has the consistency of putty so it's difficult to work with tidily. If you wet your tools it's less likely to stick to them and it does seem to make it less viscous. Then again I'm not a bricklayer so that may be down to me. The other issue is that it dries through evaporation (rather than a chemical reaction which is what cement does) so it can take a long time to dry, especially in lower temperatures and in areas such as between bricks in a circle where these is a segment shaped section of mortar. Effectively, thick sections take a long time to dry, weeks or more. Then there is a curing process that involves gradually increasing the temperature over hours, which may not work with a fire lit in direct contact with it so I may have to do a curing burn with the fire in a metal bowl held away from the surface.

Works exactly as intended - open the tub, use a filling knife and fill the crack. Smooth it over and leave it to dry, or light a small kindling fire to harden it. Cements up and goes rock hard. Colour is sandy, so goes with the vermiculite brick really well, wouldn't even know it was there. Didn't use much but it's a small tub, so hopefully the rest will keep.

It’s not the fault of the product, but I bought on the basis of a answer to a question, which stated that it is dark grey. It is not, it’s natural cement in colour. It does the job in sealing the flue joints, but I’m going to have to reorder a different cement and replace it in order to make the flue look better.

Really sturdy pot, keeps the cement useable for absolutely ages if you reseal the lid properly. Nice consistency too, easy to work when you're up to your elbow in pipe bend.

I bought this back in July 2023, only 10kg for a outdoor fire pit so I applied a pretty thin layer on the inside, it was exposed to rain, people pushing against it aswell as pretty extreme heat and several colonies of ants, lasted about a year which honestly wasn't bad considering the beating it took. Just used 40kg of it more thoroughly this time so I'll give an update on how it holds up. I would recommend adding a splash of water to it before using, as it can be a bit thick to spread around

Bought 3 of these. 1 when opened was dry and hard so virtually impossible to apply. The other 2 were cracked and had leaked when opened. They are not packed in anything protective so stand no chance of arriving intact. This meant all 3 tubs were compromised. Also one of them had the remains of a blue nitrile glove in it. Cross contamination or poor quality control? Either way, not recommended.
