FAQs

How long does it take for Firefoam B1 to cure?

The foam can be cut, sawed, or plastered after approximately one hour, provided the working temperatures are within the range of +5 to +25°C.

Can I paint over the cured foam?

Yes, once the foam is fully cured, it can be painted over to match the surrounding surfaces.

What safety precautions should I take when using Firefoam B1?

Use in a well-ventilated area. Wear gloves, eye protection, and appropriate clothing to avoid skin and eye contact. Avoid inhaling vapors.

How do I clean up uncured Firefoam B1?

Uncured foam can be messy. It's best to clean up spills immediately with a solvent cleaner suitable for polyurethane foam. Allow the foam to fully cure before attempting removal, if this is not possible.

What is the shelf life of Everbuild Firefoam B1?

The shelf life is typically 12 months from the date of manufacture when stored correctly in a cool, dry place.

Can Firefoam B1 be used outdoors?

While Firefoam B1 has fire-retardant properties, it is not UV-resistant. For outdoor applications, it should be protected from direct sunlight with paint or sealant.

What is the fire rating of Everbuild Firefoam B1?

It meets the stringent requirements of DIN 4102 Part 1 for Construction Materials; Class B and BS476 Part 20 (1987) where fire ratings up to 4 hours are achievable.

Troubleshooting

Foam is not expanding properly.

Check the can's expiry date and ensure the working temperature is within the recommended range (+5 to +25°C).

Foam is not adhering to the surface.

Ensure the surface is clean, dry, and free from contaminants. In some cases, pre-wetting the surface can improve adhesion.

No foam is dispensing from the can.

Check the nozzle for blockages. Ensure the can is shaken well before use. If the problem persists, the can may be empty or faulty.

Pros and Cons

Pros

  • Provides a high degree of fire resistance, crucial for safety.
  • Quick setting time allows for faster project completion.
  • Expands significantly, making it economical and efficient.
  • Suitable for filling a wide variety of gap sizes and shapes.
  • Offers both thermal insulation and sound dampening properties.

Cons

  • Performance is dependent on correct working temperature (+5 to +25°C).
  • Requires proper surface preparation for optimal adhesion.
  • Uncured foam can be messy and difficult to remove.
  • May require additional finishing (cutting, sawing, plastering).

Setup, Compatibility & Care

  1. Preparation: Ensure the surfaces are clean, dry, and free from dust, grease, or loose particles for optimal adhesion.
  2. Application: Shake the can vigorously for at least 20 seconds before use. Attach the applicator nozzle securely. Apply the foam sparingly, as it expands significantly.
  3. Working Temperature: Ensure the working temperature (can and surfaces) is between +5 to +25°C, ideally 20°C.
  4. Curing: Allow the foam to cure completely. The curing time is approximately 1 hour before cutting, sawing, or plastering.
  5. Post-Application: Once cured, the foam can be trimmed with a knife or saw. It can also be plastered over, if required.
