3M Fire Barrier Mortar is a lightweight, gypsum-based powder that mixes with water to form a heat-absorbing firestop for through penetrations in fire-rated floor or wall assemblies. Versatile mortar can be mixed self-leveling or non-sag, and adheres to a range of construction substrates and penetrants. It also acts as a heat sink, reducing the chance of fire on unexposed sides of the assembly.

  • Ready-to-mix pumpable mortar is deal for firestopping large annular spaces and floors
  • Lightweight mortar designed to absorb heat, reducing chance of combustion on unexposed sides
  • Polypropylene-fiber reinforced powder mixes with water for self-leveling or non-sag applications
  • Contains no asbestos, MMMF or halogens
  • Firestop tested for up to 3 hours in accordance with ASTM E 814 (UL 1479) and CAN/ULC-S115

PRODUCT FAQ

  1. What is 3M™ Fire Barrier Mortar?

    3M™ Fire Barrier Mortar is a product specifically designed to resist fire, water and sound in construction.

  2. Can it be used for both interior and exterior applications?

    Yes. The mortar can be applied on both internal as well as external surfaces with the same longevity and durability.

  3. Is this mortar safe to use around electric cables or wires?

    Absolutely. This fire-resistant barrier system has been tested by third-party laboratories to ensure its safety even when installed near electrical wiring systems or fiber-optics.

  4. How does this benefit me compared with traditional non-specialized mortars?

    With robust protective properties against adverse weather conditions such as moisture, heat, extreme cold temperatures, etc., this specialized toolset promotes superior quality results against more conventional runs-of-the-mill barriers without compromising strength.

  5. . Is there anything I need to know when installing it?

    . We recommend that the surface receiving the compound must be free of oil greases, debris dirt prior application so we would advise preparing an adequately primed layer before application for best outcomes!

A Firestop that Can Take the Heat

For mechanical and electrical through penetrations where the penetrants may generate heat, 3M™ Fire Barrier Mortar provides a ready-to-mix solution. This gypsum-based mortar acts as a heat sink, absorbing heat from penetrants and reducing the chances of combustion inside firestopped floor and wall assemblies.

Recommended Applications
  • Firestopping and sealing mechanical and electrical service penetrations
  • Blank openings and large annular spaces
  • Floors and other applications requiring self-leveling material
  • Vertical and horizontal substrates requiring non-sag adhesion
Fully Tested and Approved

3M™ Fire Barrier Mortar is firestop tested up to 3 hours in accordance with ASTM E 814 (UL 1479) and CAN/ULC-S115 when installed in listed systems, including 2-1/2" (63.5 cm) minimum thickness concrete floors. It is also tested in accordance with AS1530.4, EN1366 and ASTM E814 (UL Listed) and has proven self-bonding during fire testing.

Easy and Safe to Use

The firestop mortar comes ready to mix with potable water, making it fast and cost-effective. The versatile material can be mixed to a thinner consistency for self-leveling applications such as floors, or as a non-sag material for vertical walls. It adheres well to a range of common construction materials including concrete, metals, wood, plastic, and cable jacketing. The mortar is pumpable as well, resulting in faster work times and lower labor costs. It cleans easily with water. Polypropylene-fiber reinforced material reduces cracking during cure time. The cured material is paintable after priming. It is also re-enterable, allowing technicians to easily access components after installation with a common hole saw.

This mortar contains no asbestos, halogens, Portland cement, or MMMF and requires no fibrous damming materials or procedures.

The Science of Better Fire Protection from 3M

Since 1925 when a 3M lab assistant invented masking tape, 3M has been applying science to life – developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each adhesive, sealant, protective coating, and firestop material like 3M™ Fire Barrier Mortar – to improve performance and to help businesses like yours operate faster, better, and more efficiently.
