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.

Flexible Sealant Movement Capability

This fire barrier sealant remains pliable, allowing for typical pipe movement and construction joint shifts. The FD 150+ model accommodates ±19% movement, which helps maintain the integrity of firestop joints under stress.

Its multi-viscosity grade offers excellent caulking properties, making it suitable for sealing around piping, cables, and construction joints. This flexibility ensures long-lasting protection in dynamic building environments.

High-Performance Fire Resistance

The FD 150+ sealant is tested for fire resistance up to 4 hours according to ASTM E 1966 (UL 2079) and up to 3 hours per ASTM E 814 (UL 1479) and CAN/ULC S115 standards. This makes it ideal for firestop joints and through penetrations in fire-rated walls and floors.

Its high-solids formula limits shrinkage, ensuring a continuous and effective fire barrier. The sealant also acts as an acoustic barrier, minimizing noise transfer with an STC rating of 56 in tested assemblies.

Easy Application And Cleanup

3M Fire Barrier Sealant FD 150+ is water-based, which simplifies installation, cleanup, and disposal. It dries to the touch within 30 to 60 minutes and can be painted to match surrounding surfaces, enhancing aesthetic integration.

This product is sag-resistant and compatible with conventional caulking equipment, making it user-friendly for contractors. Its re-enterable and repairable nature allows for maintenance and adjustments after initial installation.

Ample Size And Packaging

The sealant is supplied in a 4.5 Gallon pail, providing enough material for extensive firestop projects. This packaging format supports efficient use on commercial, industrial, and residential applications where large volumes are needed.

Each drum contains one pail, ensuring straightforward inventory management and reducing packaging waste. The red color helps with easy identification on job sites, streamlining workflow and safety checks.
