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 trusted solution designed to provide reliable fire protection. This white, latex-based sealant comes in a 20 fl oz sausage pack format, ensuring easy application and consistent performance. Its elastomeric nature allows it to cure into a flexible firestop seal that helps control fire, smoke, and noxious gases.

With a pack count of 12 each per case, this sealant is ideal for commercial and industrial projects requiring dependable fire resistance. The FD 150+ model is tested to meet rigorous standards, offering peace of mind for fire-rated building partitions and assemblies.

Flexible Sealant Movement Capability

This fire barrier sealant features a continuous seal that remains pliable, allowing for typical pipe movement and construction joint expansion. The FD 150+ grade supports ±19% movement, which helps maintain the integrity of firestop joints under stress or shifting conditions.

Its multi-viscosity grade ensures excellent sealant and caulking properties, making it suitable for various substrates and applications. This flexibility is essential for installations involving piping and cables, where movement is common.

High-Performance Fire Resistance

The FD 150+ sealant provides fire resistive joint protection tested up to 4 hours in accordance with ASTM E 1966 (UL 2079). It also offers firestop performance up to 3 hours per ASTM E 814 (UL 1479) and CAN/ULC S115 standards, ensuring robust fire containment.

This high level of fire resistance makes it suitable for use in floor slabs, walls, and other fire-rated building partitions. The sealant’s high-solids formula limits shrinkage, maintaining a consistent barrier during fire exposure.

Easy Application And Cleanup

Designed for convenience, the 20 fl oz sausage pack format allows for smooth dispensing using conventional caulking equipment. The water-based formula simplifies installation, cleanup, and disposal, reducing labor time and effort on site.

The sealant dries to the touch within 30 to 60 minutes and can be painted over, offering aesthetic flexibility. Its re-enterable and repairable nature means maintenance and adjustments can be made without replacing the entire seal.

Noise Reduction And Pack Count

Beyond fire protection, the 3M Fire Barrier Sealant FD 150+ helps minimize noise transfer, acting as an acoustic barrier with an STC rating of 56 when tested in a rated wall assembly. This dual function enhances building comfort and safety.

Available in a pack count of 12 each per case, this product supports efficient project planning and inventory management. The white color ensures a clean, professional finish that blends well with most construction materials.
