How To use Firesilicone B1 FR, fire rated silicone sealant?

  • Take care to follow the standard industrial hygiene methods for applying sealants. Make sure to clean the surface and remove all traces of dust and grease.
  • If the sealant is applied to porous substances, Primer 150 should be used to prime the surface. It is recommended that a preliminary compatibility test be conducted before you proceed.
  • To enhance the adhesion properties on smooth surfaces, we advise you to use Soudal Surface Activator.
  • Use a caulking gun as the method of delivery for maximum impact.
  • As for backing material, we suggest the use of PE backer rods for correct joint dimensions.
  • Take care that during the application, the atmospheric temperature does not exceed room temperature conditions.
  • After application, clean the caulking gun with white spirit immediately. If the sealant cures, then it has to be mechanically removed by chipping it off.
  • Finish the applied sealant properly by using a soapy solution.
