Firecement HT° - High Temperature Cement Sealant

Firecement HT° - High Temperature Cement Sealant

Soudal | High Temperature Cement Based Sealant

Soudal Firecement HT° is a High Temperature Resistant Fire Cement Sealant which cures to form a hard setting seal and withstands temperatures of up to 1500°C.

  • Heat resistant up to 1500°C

  • Does not contain asbestos or other harmful components

  • Hard setting

  • Does not crumble or crack after cure

  • Fire Rating of 120 minutes (Test Report 7830).


Typical Applications:

  • Suitable for Internal Use

  • Sealing of joints and openings at furnaces, heating systems, central heatings, barbecues, etc.

  • Heat retardant sealing at existing constructions

Surface Preparation:

Surfaces should be clean, dry, free of dust and grease.

For use on brickwork, concrete and metals.

Slight moistening of the surface will increase adhesive strength

We recommend a preliminary adhesion test on every surface.

Application Method:

  • Application Method: With a manual or pneumatic caulking gun, spatula or a trowel.

  • Cleaning: Clean uncured product with a water immediately after use.

  • Repair: With the same material

Joint Dimensions:

  • Minimum Width for Joints: 5 mm

  • Maximum Width for Joints: 15 mm


  • A slight heating up of the installation during 12 hours after application of Firecement HT° will prevent the forming of bubbles and improve the sealant structure.

  • Do not apply in situations where constant water immersion is possible
