Firecement HT
Sealants Specialist formulation

Soudal Singapore product

Firecement HT

A hard-setting sodium-silicate paste designed for static interior joints and openings exposed to high temperatures.

Product description

Where it fits

Static interior joints and openings in suitable stoves, ovens, fireplaces, flues and heating equipment.

High-temperature performance

Firecement HT cures to a rigid seal and is documented for temperatures up to 1500°C. It is designed for static, dry details rather than flexible movement joints or areas with standing water.

Preparation and applicationFollow the product instructions step by step.

Use the guidance and documents for your chosen product. Contact us if the English TDS or SDS you need is not listed below.

  1. 01

    Confirm that a hard-setting, non-elastic filler suits the detail. These products are intended for static joints and openings, not for joints that move or carry structural load.

  2. 02

    Clean the joint or opening back to sound material and remove soot, ash, grease, dust and loose deposits.

  3. 03

    Where the substrate is porous or very dry, dampen it lightly if the technical data sheet calls for it, so the paste does not dry out too quickly.

  4. 04

    Fill the opening solidly through its full depth without voids, then smooth the surface before the paste begins to skin.

  5. 05

    Allow the stated drying time, then raise the appliance to temperature gradually so the filler hardens without cracking.

For the best resultMatch the product to the materials and application.

These practical points help you achieve a reliable result.

  • The product sets hard and does not accommodate movement. Use an appropriate elastic sealant where the joint moves.
  • Match the stated temperature rating to the real service temperature at the joint rather than to the appliance’s peak output.
  • For passive-fire or flue-gas-tightness requirements, follow the tested construction and its documentation rather than the product alone.
  • For the best result, follow the current technical and safety information for the selected product.
  • For unfamiliar materials, coatings or site conditions, test adhesion and compatibility on the prepared surface first.
