Technical Data Sheet


  • Shake the can for at least 30 seconds. Open the cover and unfold the tube into a horizontal position. Hold the can upside down and extrude the foam. Gaps are to be filled partly (approx. 1/3). Repeat shaking regularly during application. If you have to work in layers repeat moistening after each layer. Slightly humidifying of the surfaces gives faster curing and a better cell structure. For storage: detach the bung, seal the nozzle, close the cap and store can upright.
  • Ideal for filling and insulating of gaps around roofing and insulation materials. Adheres to most roofing and insulation materials. Can also be used for other gap filling applications.
