What temperature can it withstand?
Up to 1250 °C once cured, which suits flue pipes, firebacks, stoves and continuously burning fires.
Can I use it outside or on a chimney pot?
No. It is water soluble, so it is for internal, dry locations only and must not be used where rain or water can erode the joint.
Does it need firing to set?
It air dries and then sets rock hard as it is exposed to heat and air in use.
What is it typically used for?
Fitting fires, jointing iron flue pipes, building and repairing firebacks, and mending cracked bricks in grates and stoves.
What colour is it?
Buff. It is a blend of high quality clays and selected fillers.
