Installation Techniques

Preparatory Work

  • The surface of the opening and any penetrating items should be clean and free of dirt and debris to allow for the proper adhesion of 3M™ Fire Barrier Water Tight Sealant.
  • Do not use alcohol to clean surfaces in penetration or joint opening, instead use a commercial solvent such as mineral spirits, xylene, toluene or methyl ethyl ketone (MEK). 
  • Ensure that the surface of the substrates are not wet and are frost free. Sealant can be installed with a standard caulking gun, pneumatic pumping equipment or it can be easily applied with a putty knife or trowel. 

Installation Details

  • Install the applicable depth of backing material, if required, as detailed within the applicable UL, cUL, ULC, Intertek or other third-party listed system.
  •  Cut the end of the 3M™ Fire Barrier Water Tight Sealant tube spout to achieve the desired beadwidth. 
  • Install the applicable depth of 3M™ Fire Barrier Water Tight Sealant into the opening flush with the surface of the substrate,or as detailed within the applicable listed system, at the required depth for the assembly and rating that is specified. 
  • Tool within 5 minutes. 
  • Clean all tools immediately after use with a commercial solvent such as mineral spirits, xylene, toluene or methyl ethyl ketone (MEK). 

Limitations: 

  • Do not apply 3M™ Fire Barrier Water Tight Sealant 1000 NS (Note: once applied,sealant may be exposed to intermittent water — exhibits excellent weatherability when fully cured) or frost-coated, in unvented spaces where sealant is not exposed to atmospheric moisture, in areas where abrasion or physical abuse of the sealant are likely and/or where painting of sealant is required. 
  • Do not apply 3M™ Fire Barrier Water Tight Sealant 1000 NS to polycarbonates or to building materials that bleed oil, plasticizers or solvent (e.g. impregnated wood, oil-based sealants, or green or partially vulcanized rubber). 
  • Note: In confined cure conditions there may be discoloration of brass, copper or other sensitive metals.
