3M Fire Barrier Water Tight Spray, White, 5 Gallon (Pail), Drum

• CPVC compatible
• Helps minimize noise transfer (STC Rated)
• Meets UL Water Leakage Test, W-Rating— Class One requirements for systems tested and listed in accordance with ANSI/UL 1479
• Seals interior construction voids
• Superior washout resistance – Passes ASTM D 6904 24 hour exposure after 2 hour cure time
• Up to 3-hour fire protection in construction joints per ASTM E 1966 (UL 2079)

Fire Barrier Watertight Spray is a sprayable, moisture-curing hybrid siliconized polymer that forms a tough, elastomeric coating. This material is used to firestop perimeter joints (curtain wall joints) and other construction joints that need to prevent fire and water from moving floor to floor.

First Line of Defense
3M™ Fire Barrier Watertight Spray helps control twill act as a barrier to water leakage and airborne sound transmission, while helping to control the transmission of fire, heat and smoke before, during and after exposure to fire. It is a sprayable, moisture-curing hybrid siliconized polymer that forms a tough, elastomeric coating. This material is used to firestop perimeter joints (curtain wall joints) and other construction joints that need to prevent fire and water from moving floor to floor. The spray meets UL Water Leakage Test, W Rating – Class 1 requirements for systems tested and listed in accordance with ANSI/UL 1479 and is tested in accordance with ASTM G 21 standard practice for determining resistance of synthetic polymeric materials to fungi. This spray provides remarkable adhesion on most construction surfaces, including: concrete, gypsum, metal, plastic, wood and insulation. The seal is for interior construction voids such as blank openings, metallic pipes, non-metallic pipes, cables, cable trays, insulated pipes, busways, HVAC vents and ducts, combos and construction joints.

Recommended Applications

• Firestopping
• Smoke sealing
• Water sealing

The Science of Better Fire Protection from 3M
Since 1925 when one of our lab assistants invented masking tape, 3M has been applying science to life –developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each of our adhesives, sealants, protective coatings, devices and the best ways to used them – including Fire Barrier Pass-Through Device Brackets to improve performance, and to help businesses like yours operate faster, better and more efficiently.

Trusted 3M Fire Barrier

The 3M Fire Barrier Water Tight Spray is a reliable solution designed for firestopping needs. This product comes in a 5 Gallon pail, making it suitable for larger projects requiring consistent application. Its white color ensures easy visibility during and after application.

Specifically formulated by 3M, this spray helps control fire, heat, and smoke transmission in construction joints. The exact model name, "3M Fire Barrier Water Tight Spray," guarantees you’re getting a tested and proven fire protection product.

Effective Noise And Water

This spray helps minimize noise transfer with an STC rating, making it ideal for environments where sound control is important. It also acts as a watertight barrier, meeting UL Water Leakage Test W-Rating Class One requirements.

Its ability to seal interior construction voids prevents water leakage and airborne sound from passing through joints. This makes it perfect for curtain wall joints and other perimeter joints in buildings.

Durable 5 Gallon Format

Provided in a 5 Gallon pail, this format supports large-scale applications without frequent refills. The size is convenient for contractors and builders who need a reliable quantity for extensive firestop projects.

The large volume also ensures consistent coverage and reduces downtime during application. This format suits commercial and industrial construction sites requiring durable fire barrier solutions.

Compatible With CPVC

The spray is CPVC compatible, allowing it to be used safely around CPVC piping and materials. This compatibility expands its use in various construction settings where CPVC pipes are common.

It adheres well to multiple surfaces including concrete, metal, wood, and plastic. This versatility ensures the spray can be applied effectively across different construction materials.

Reliable Fire Protection

This product provides up to 3 hours of fire protection in construction joints, tested per ASTM E 1966 (UL 2079). This level of protection is critical for maintaining safety standards in building construction.

Its superior washout resistance, passing ASTM D 6904 after 24 hours exposure, ensures durability even in challenging conditions. This makes it a dependable choice for long-lasting firestop applications.
