FAQs About Everbuild B2 Gun Grade Expanding 2-Hour Fire Foam 750ml

1. What is Everbuild B2 Firefoam Gun Grade Expanding Foam, and what are its key features?
The Everbuild B2 Fire foam Gun Grade Expanding Foam is a fire-rated polyurethane foam designed to provide up to 2 hours of fire resistance. It is applied using a foam applicator gun, ensuring precise control and even application. This foam expands to fill gaps, joints, and service penetrations, creating a durable fire-resistant barrier that helps prevent the spread of flames, smoke, and gases. Its B2 fire classification makes it suitable for areas where enhanced fire safety is required, and its strong adhesion allows it to bond to a wide range of construction materials.

2. Where can this Gun Grade foam be used?
This fire foam is ideal for sealing and insulating in various fire-rated applications, including:

• Door and window frames: Creating fire-resistant seals around frames.
• Service penetrations: Sealing gaps around pipes, cables, and ducts in fire-rated walls and floors.
• Construction joints: Filling expansion and perimeter joints in fire-rated walls and ceilings.
• It is suitable for use in residential, commercial, and industrial projects where fire safety compliance is essential.

3. How does the foam achieve its fire resistance, and what testing has been conducted?
The foam’s fire-resistant properties come from its specialized fire-retardant formulation, which prevents ignition and slows down the spread of fire. It has been rigorously tested to meet B2 fire classification standards and provides up to 2 hours of fire resistance when installed correctly. This testing ensures it complies with fire safety regulations and can effectively protect against the spread of fire in fire-rated systems.

4. Can this gun grade foam bond to different materials, and how should surfaces be prepared?
Yes, the foam bonds well to a variety of materials, including wood, metal, concrete, brick, and plaster. For best results, ensure all surfaces are clean, dry, and free from dust, grease, or loose debris before application. Using a foam applicator gun allows for precise application and ensures optimal adhesion to the substrate. The foam expands to fill gaps and maintains strong bonds over time, even in challenging environments.

5. What precautions should I take when using this foam, and how do I clean up excess?
During application, always wear appropriate personal protective equipment (PPE), including gloves and eye protection, and work in a well-ventilated area. Avoid inhaling fumes or allowing the foam to come into contact with skin. Excess foam can be cleaned with a foam cleaner or acetone before it cures. Once cured, it hardens and can only be removed mechanically by cutting or scraping. To prevent excessive application, apply the foam sparingly and allow it to expand naturally to fill gaps. Always follow the manufacturer’s guidelines for safe use and proper installation.
