We recommend the use of fire cement in place of the traditional gun injectable mortar when you are using brick slips on applications subject to extreme heat. Such examples include log burning stoves.
KOS Fire Cement is a ready mixed blend that sets when it is exposed to heat. The resulting mortar is temperature resistant up to 1250°C.
It can be used for domestic and commercial applications, for installation and repair work. See our accessories page for our line of Fire Cerment.
We offer the fire cement in either:
- a tub size of 2kg which covers approximately 0.5 m2 per tub
- a tube, which can be used in conjunction with our gun applicator
- Colour : Light Grey/ Buff (tubs)
- Light Grey/ Buff and black (in the cartridges)
The colour of this product can change from batch to batch.
Top tip! Please order the correct quantity for your project as we can not guarantee future orders will be from the same batch.
Benefits of using KOS cement
This product is very easy to apply and you can use directly from tub or the handy gun injectable cartridge.
If using from the tub, initially you can soften with a small amount of water if required. Then, work well into the joints.
How long does it take for fire cement to dry?
On average it takes around 12 hours to dry out.
After applying, gradually increase heat over a 4 hour period. Make good any cracks which may form with fresh cement to form a smoke tight seal.
