3M Fire Barrier Sealant FD 150+ is a gun-grade, latex-based, elastomeric sealant that cures upon exposure to the atmosphere to form a monolithic flexible firestop seal. When properly installed, this sealant helps control the spread of fire, smoke and noxious gasses before, during and after exposure to a fire and exhibits excellent adhesion to a full range of construction substrates.

Tried and Tested Fire Protection
Ready-to-use, 3M™ Fire Barrier Sealant FD 150+ is a latex-based elastomeric sealant. This gun-grade sealant cures when dispensed to form a monolithic flexible firestop seal and, when properly installed, this product provides up to 4-hour fire protection in tested and listed systems. We formulated this sealant to help prevent the spread of fire, smoke and noxious gas and firestop joints and through penetrations through floor slabs, walls and other fire-rated building partitions and assemblies. This firestop sealant offers a continuous seal with ± 19% movement capability for construction joints and typical pipe movement and exhibits excellent adhesion to a full range of construction substrates.

Recommended Applications

• Construction joints
• Piping, all non-combustible and small diameter combustible
• Cables

Fire Barrier Features
3M™ Fire Barrier Sealant FD 150+ acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 56 when tested in a STC 56-rated wall assembly). We designed this fire barrier sealant to be water-based for easy installation, cleanup and disposal. In addition, the high-solids formula produces limited shrinkage. This halogen-free sealant is sag-resistant and has an excellent caulk rate (applied with conventional caulking equipment). It dries to the touch in 30 – 60 minutes and can be painted. In addition, this sealant has been engineered to be re-enterable and repairable.

Reliable and Affordable Fire Protection
Effective and easy to install, 3M™ Fire Barrier Sealant FD 150+ is part of our family of fire protection products that offer the broadest, long-lasting solutions for a variety of commercial, industrial and residential applications. As a trusted leader in the fire protection industry, 3M offers a broad line of affordable products designed to meet the most demanding firestop requirements.

Trusted 3M Fire Protection

The 3M Fire Barrier Sealant FD 150+ is a reliable firestop solution designed to control fire, smoke, and noxious gases. This red, latex-based sealant cures to form a flexible, monolithic firestop seal that supports up to 4 hours of fire resistance.

Its gun-grade cartridge format, containing 28 fl oz each, ensures easy application. The sealant’s elastomeric properties allow it to maintain its integrity under typical pipe movement, making it ideal for various construction needs.

Flexible Sealant Movement Capability

This fire barrier sealant offers a continuous, pliable seal that accommodates ±19% movement, which is crucial for construction joints and pipe installations. The FD 150+ model supports typical pipe movement without compromising the fire barrier.

Its multi-viscosity grade enhances sealant and caulking properties, ensuring excellent adhesion across different substrates. This flexibility helps maintain fire protection even when building materials expand or contract.

High-Solids Formula Benefits

The FD 150+ sealant features a high-solids formula that limits shrinkage during curing. This characteristic helps maintain a consistent seal over time, reducing the risk of gaps that could allow fire or smoke to pass through.

Additionally, the water-based composition simplifies installation, cleanup, and disposal. This makes the 28 fl oz cartridge format practical for both professional and on-site use, supporting efficient firestop applications.

Comprehensive Fire Resistance Ratings

This 3M fire barrier sealant has been tested to meet rigorous standards, providing up to 4 hours of fire resistive joint protection under ASTM E 1966 (UL 2079). It also offers up to 3 hours of firestop protection per ASTM E 814 (UL 1479) and CAN/ULC S115.

These certifications confirm the FD 150+ cartridge’s effectiveness in various fire-rated building partitions, including walls and floor slabs. Its red color helps easily identify the product during inspections and installations.

Convenient Packaging And Applications

Each case contains six 28 fl oz cartridges, making it easy to stock and distribute for large projects. This pack size supports continuous work without frequent reordering, ideal for commercial and industrial firestop needs.

The sealant is recommended for construction joints, piping (non-combustible and small diameter combustible), and cable penetrations. Its re-enterable and repairable nature adds value by allowing future maintenance without full replacement.
