International Fireproof Technology CFS01 Fire Rated Mortar

CFS01 Fire Rated Mortar is an industry-leading non-intumescent firestop mortar comprised of a proprietary blend of gypsum and cement. CFS01 Mortar is designed with installation convenience in mind. Our "Variable Viscosity" technology allows the installer to add less water for a thicker consistency or more water for a thinner consistency, depending on the application needs. CFS01 Mortar provides up to 3 hours of fire rating to prevent the passage of flame, smoke, and toxic fumes.

Installation Guide
  • Before applying, clean the surface of the opening and any penetrating items to allow for proper adhesion.
  • Use mineral spirits or similar products to clean surfaces (Do not use alcohol).
  • Ensure that the surface of the substrates is dry and frost-free.
  • Install the correct depth and compression of backing material, if required, as detailed within the applicable Listed system.
  • INSS2460 can be installed with a caulking gun, putty knife, or trowel. INSS2460+ can be applied by an airless sprayer.
  • Install the applicable depth of INSS2460/INSS2460+ into the opening flush with the surface of the substrate, or as detailed within the Listed system to meet the required assembly rating.
  • Tool the sealant surface smooth using a putty knife dipped in water making complete contact with substrates to ensure an air and smoke tight seal.
  • Using mineral spirits, clean all tools and flush spray equipment immediately after use.
