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.

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 blue, latex-based sealant cures to form a flexible, monolithic firestop seal that supports up to 4 hours of fire resistance.

Its gun-grade format in a 20 fl oz sausage pack ensures easy application. The sealant’s elastomeric properties allow it to maintain a continuous seal even with typical pipe movement, making it a dependable choice for fire-rated assemblies.

Flexible Sealant Movement Capability

Designed to remain pliable, this sealant accommodates ±19% movement, which is essential for construction joints and pipe penetrations. This flexibility helps maintain the integrity of fire barriers under normal building shifts and vibrations.

Its multi-viscosity grade offers excellent sealant and caulking properties, ensuring a tight fit around various substrates. The 3M FD 150+ supports both non-combustible and small diameter combustible piping applications.

High-Solids Formula Benefits

The high-solids formula of this 3M sealant limits shrinkage after curing, preserving the seal’s effectiveness over time. This characteristic helps maintain a consistent fire barrier without gaps or cracks that could compromise safety.

Applied in a 20 fl oz sausage pack, the sealant is easy to handle and apply with conventional caulking equipment. Its water-based nature also simplifies cleanup and disposal, making installation more efficient.

Durable Blue Sausage Pack

This product comes in a convenient 20 fl oz sausage pack, allowing for precise dispensing and minimal waste. The blue color helps visually confirm proper application and coverage during installation.

Sold in cases of 12, this packaging supports larger projects and ensures consistent supply. The sausage pack format is compatible with standard caulking guns, streamlining the application process on site.

Comprehensive Fire Barrier Features

3M Fire Barrier Sealant FD 150+ offers tested fire resistance up to 4 hours per ASTM E 1966 and up to 3 hours per ASTM E 814 standards. It also acts as an acoustic barrier, minimizing noise transfer with an STC rating of 56 in rated wall assemblies.

Re-enterable and repairable, this sealant supports maintenance and adjustments after installation. Its water-based, halogen-free formula dries quickly and can be painted, providing both safety and aesthetic flexibility.
