Sparks can cause fires. Pre-soak the hot-work area and provide a heat barrier. The Dual applicator provides a foam or non-foam layer.

Metal stock reaches extreme temperatures when welding. Accidental drops and surface conditions increase risk of fire. Apply with no clean-up for peace of mind.

Brazing or Soldering near roofing materials and or sub-framed penetrations requires above average due diligence. Soak deep down between flashing and roofing conditions where soldering poses a fire threat. Adheres to any angle and surface.
