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.

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.

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.
