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+ offers reliable fire protection with its latex-based, elastomeric formula. This 20 oz. sausage pack sealant is designed to form a flexible firestop seal that helps control fire, smoke, and noxious gases effectively.

Its tested fire resistive joint system provides up to 4 hours of protection, meeting ASTM E 1966 (UL 2079) standards. The product comes in a convenient 12 each per case pack, making it easy to stock and use on multiple projects.

Flexible Sealant Movement Capability

This FD 150+ sealant maintains a continuous, pliable seal that accommodates typical pipe movement with ±19% flexibility. Its multi-viscosity grade ensures excellent sealant and caulking properties for various construction needs.

Ideal for construction joints and piping applications, the sealant’s flexibility helps maintain fire barriers even when subjected to movement, ensuring long-lasting protection in dynamic environments.

High-Quality Firestop Performance

The 3M Fire Barrier Sealant FD 150+ is tested for firestop performance up to 3 hours under ASTM E 814 (UL 1479) and CAN/ULC S115 standards. This makes it suitable for sealing penetrations through walls and floors in fire-rated assemblies.

Its high-solids formula limits shrinkage, ensuring the seal remains intact over time. The sealant is also re-enterable and repairable, allowing for maintenance without compromising fire protection.

Easy Installation And Cleanup

This water-based sealant simplifies installation and cleanup, reducing labor time and waste disposal concerns. The 20 oz. sausage pack format fits standard caulking guns, making application straightforward and efficient.

Drying to the touch within 30 to 60 minutes, the sealant can be painted over to match surrounding surfaces. Its sag-resistant nature and excellent caulk rate enhance ease of use on vertical and overhead joints.

Noise Reduction And Pack Size

Besides fire protection, the FD 150+ sealant acts as an acoustic barrier, minimizing noise transfer with an STC rating of 56 in rated wall assemblies. This dual function improves building comfort and safety.

Available in a 12 each per case pack, this product is ideal for commercial and industrial projects requiring consistent supply and reliable performance. The white color blends well with most construction materials.
