  • Applied with conventional caulking equipment with excellent caulk rate
  • Sag-resistant properties offer clean application as well as strong adhesion

This sealant is designed to help control the spread of fire, smoke, and noxious gases. This is before, during and after exposure to a fire when installed in accordance with a listed through-penetration or fire-resistive joint assembly system (STC-Rating of 54 when tested in a STC 54-rated wall assembly).

Ready to Protect for Consistent Results
