The paste consistency material withstands very high temperatures. It sets rock hard when exposed to heat or at room temperature, although the process takes longer at a lower temperature. It's classified as an air-setting material. Fire cement can be utilised in any application with temperatures up to 1250°C.
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
- As a heat-resistant product, it can be used on a variety of surfaces wherever there is a 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.
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 firebacks in fireplaces, gas cookers, stoves and ranges, central heating systems and boilers,
- repair firebacks for jointing internal flue pipes and on all structures subject to temperatures up to 1250°C,
- join internal flue pipes especially the first joint between the flue pipe and the spigot of the stove,
- seal ceramic flue liners in a chimney,
- seal against the escape of flue gases and smoke.
