Overview:

Soudal Black Firecement High Temperature Engineering Sealant mortar fire cement supplied in a handy 300ml Cartridge form which will fit in any Heavy Duty 310ml or 400ml Standard Sealant Gun. Soudal FireCement HT Black is a ready-to-use, hard-setting fire cement designed for sealing and repairing joints exposed to very high temperatures.

Supplied in a cartridge for clean, controlled application, it’s ideal for use around stoves, ovens, fireplaces, flue connections and other heat-stressed areas where a rigid seal is required. Once cured, it forms a solid, heat-resistant joint that can withstand extreme temperatures up to 1500°C. It is asbestos free and suitable for interior applications, making it a dependable choice for maintenance and installation work on domestic and commercial heating systems.

Soudal FireCement HT Black – Key FAQs

• What is FireCement HT used for?
  It’s used for sealing and repairing high-temperature joints on stoves, ovens, fireplaces and similar installations where a hard, heat-resistant seal is needed.

• How heat resistant is it once cured?
  When fully cured, it can withstand temperatures up to 1500°C, making it suitable for very high-temperature sealing tasks.

• Does it stay flexible like silicone?
  No. It cures to a hard-setting joint, which is ideal for rigid heat-exposed areas but not suitable where significant movement is expected.

• What joint width should I apply?
  It’s typically used in joints between 5mm and 15mm wide to achieve a solid seal and good performance after curing.

• Can it be used in permanently wet areas?
  No. It isn’t suitable for permanently standing water or constant immersion, as this can affect the integrity of the cured joint.

• Can it be used on all surfaces?
  It’s designed for rigid, clean substrates such as brick, concrete and metals. Always test adhesion first on unusual or coated surfaces.

• How do I clean up after use?
  Clean tools and any excess with water before it cures. Once cured, it must be removed mechanically.

• Will the colour stay black?
  Prolonged exposure to very high temperatures may cause the colour to lighten, which is normal for fire cement products in extreme heat zones.

Important Notes

• Cartridge format fits standard heavy duty sealant guns (cartridge size compatible with common 310ml guns).

• Not recommended where materials have very different expansion rates, as cracking can occur under repeated heat cycling.

• Always read the latest Technical Data Sheet before first use to confirm suitability and correct application guidance.

Always Read the Official Firecement HT Technical Data sheet prior to use to make sure you have all the details are correct and that there have not been any changes to instructions.
