Fire cement

The paste consistency material which will withstand very high temperatures. It sets rock hard when exposed to heat or at room temperature, although the process takes longer the lower the temperature. It is believed to have been discovered towards the end of the 19th Century and is classified as an air setting material. Fire cement can be utilised in any application with temperatures up to 1250oC.
Given below are some of the main characteristics of fire cement:

  • Easy to use material
  • Provides extremely tight joints to fumes and smoke
  • When allowed to dry and exposed to heat, it strengthens and becomes a very hard seal
  • It has very strong properties of adhesive even at very high temperatures
  • Can be used on a variety of surfaces wherever there is high amount of heat
  • When set it has strong adhesion to metal surfaces as well as to ceramic type materials such as fire bricks, concrete, and other masonry materials.

Domestic appliations

In domestic situations this translates to a very versatile and useful product both for installation and repair applications.
Fire cement can be used to:

  • repair small cracks and small patches of damage to fire bricks and fire backs in fireplaces, gas cookers, stoves and ranges, central heating systems and boilers,
  • repair fire backs for jointing internal flue pipes and on all structures subject to temperatures up to 1250ºC,
