Soudal Firecement HT, Black - 300ml (Box of 12)

If you need a gap filler that can really take the heat, there’s nothing better than Soudal’s Firecement HT. A sodium-silicate based substance brewed up by the expert chemists and engineers at Soudal, Firecement HT is perfect for repairing fireplaces, ovens, and even most ceramic kilns. It can also be used to help fireproof other existing structures. Even if it’s just a join where any gap filler would be exposed to high temperatures, Firecement HT will get the job done.

Firecement HT can handle temperatures up to an astonishing 1500 degrees Celcius. That’s hotter than most lava! This hard-setting gap filler is also completely free of asbestos. It can be applied either manually with a filling knife or spatula, or with a sealant gun. Firecement HT can seal gaps up to 15mm wide.
