Product description

Where it fits

Calofer seals joints on stoves, ovens, fireplaces and other heat-exposed interior details in brick, concrete and metal. It is applied with a spatula, filling knife or cartridge gun into joints between 5 mm and 15 mm wide, and dries physically to a rigid seal.

Calofer or Firecement HT?

Both are sodium-silicate pastes with the same 1500°C temperature resistance, so the choice is about evidence rather than heat. Firecement HT’s current sheet documents a 120-minute fire rating; Calofer’s does not. Where a fire-resistance classification is required, specify a product whose documentation covers the tested construction.

Key properties

Temperature resistance of −40°C to +1500°C once fully cured
Rigid and non-elastic after drying, with a maximum deformation of about 2%
Anthracite, and free of asbestos
For interior use, and not for permanent contact with standing water

Before you specify it

Soudal currently publishes the Calofer technical data sheet in French only. The Singapore team supplies the current technical and safety information for your enquiry, together with the pack available locally.

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.

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.
02
Clean the joint or opening back to sound material and remove soot, ash, grease, dust and loose deposits.
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.
04
Fill the opening solidly through its full depth without voids, then smooth the surface before the paste begins to skin.
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.

Calofer’s current documentation records temperature resistance, not a fire-resistance classification. Where a fire rating is required, specify a product whose evidence covers the tested construction.
The product dries rigid and accommodates only about 2% deformation. Use an elastic sealant where the joint moves.
For interior use only, and not for permanent contact with standing water.
Soudal currently publishes this product’s technical data sheet in French only, so the Singapore team confirms the applicable details for each enquiry.
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.
