SabreFix SF is a one-component, ready to use polyurethane straw foam for various building applications, e.g., filling of holes, sealing of joints and penetrations, thermal and acoustic insulating. SabreFix SF ensures good results in winter conditions, and can be used in temperatures from -10 °C to +30 °C.  The foam has good volume expansion for effective filling.

SabreFix SF does not shrink after curing keeping the risk of deformation of joints and separation from the surface minimal. Adheres well to most materials like wood, concrete, stone, plaster, metal, PVC and polystyrene.

How to use

  • Substrate Preparation

    Ensure substrates are clean, dry and free of dust and grease. Priming is not required.

  • Application

    Shake can well before use (about 20 times). Carefully fix nozzle. Only partially fill cavities as the foam will expand to fill the remaining space. When used for fixing door frames, supports must be used until the foam is fully cured.

  • Cleaning

    Any excess foam can be removed whilst still wet with Sabre FC Foam Cleaner. Cured foam must be removed mechanically.
