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

Arrived early and was a brilliant product, and fairly priced.

Did a good job sealing the pipe from my wood burner.

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.

Great product, managed to re use after 3 years what was left in the pot as long as stored upside down

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

Bought for repair to a 1950's fire lining which was needing repair. Needs a clean surface, use a wire-brush to release soot and remove dust with a vacuum cleaner . Used as both for cementing fire bricks together and facing the repair to leave a smooth surface. If you have a tollerant wife, keep it in the fridge after opening, keeps better, will harden at "room temp". 6Kg might seem a lot but have used 1/2 relining the fireplace and have the "floor", under the grate to do yet. Tools, a filling knife, or narrow scraper and a small trowel, pointing one,not a bricklayers one, too large ! Wear protective gloves, "Riggers Gloves" are ideal. Apply, damp the area with a brush dipped in water first, not too wet ! Apply cement, level off, leave for 24 hours to cure. I asked for a quote from a Hetas tradesman, too busy for 2 months, do not know what a "Het" is, an "as", you decide. I have completed a brick layers course and fire marshal course, with proper care, fireplace repair can be safely done, by one with the ability to use hand tools.

Used Kos for decades, so easy to use A child of five can use it, if you see A crack appearing open the plastic can remove the inner plastic seal fill in the crack with Kos smooth it over with an old cutlery knife allow it to set for A couple of hours then light your fire. It bakes the fire cement into A 'Rock like', seal preventing fumes or smoke from escaping guys, PS! Remember before closing the lid to put the clear moisture seal back before clicking the tub shut, If you don't and you store it somewhere warm it will go hard in the tub Fondest Regards

A good cement that is easy to apply and dries to a hard finish without cracking. Worked well to seal my wood burner chimney. Only complaint is that it dries grey not black. I'm just going to over paint with matt black high heat paint. Otherwise perfect.

Lo uso per ricostituire annualmente un particolare della caldaia a pellet. È un ottimo prodotto che mi permette di non sostituire il ricambio originale che non riesco più a trovare

il cemento refrattario è già miscelato e pronto all'uso. Ha svolto in modo egregio la sua funzione, coprire giunti e chiudere buchi nei mattoni refrattari.
