Exposed tofire, the material starts expanding at a temperature of 140°C and forms a solid, heat-insulating carbon foam, which prevents the further spreading of fire and smoke.

Application and Adhesion

The application surface should be clean, dry and free from dust and grease. Firestop Putty must be injected directly into the joints and cavities with a hand-or blow-gun and then smoothed with a wooden jointing tool orspatula. The smoothing is made easier if the tool is moistened with water.
We recommend always wearing protective covering when using Firestop Putty.

For outdoor use, it is imperative to applya protective covering against outdoor weathering exposure. In this case the Firestop Putty must be injected correspondingly deeper. The joint width must not be less than 5mm.

  • Hardening: Firestop Puttyhardens when the water content of the sealant evaporates.
  • Cleaning: Freshly applied sealant can be simply removed with a damp cloth.
