Soudal B1 Fire Class Expanding Foam Handheld - 750ml (Box of 12)

Uses

The B1 Trade Expanding Foam by Soudal is an excellent expanding foam, ideal for various applications throughout a building. It's ideal for installing windows and door frames, general cavity filling, and sealing openings in roof construction. It improves thermal isolation in cooling systems and is an excellent versatile gap filler. It offers outstanding adhesion to all surfaces, excluding PE, PP and PTFE.

Preparation

Due to its excellent adhesion properties, minimal preparation is required. Using a stiff brush to remove small debris is good practice, as it focuses on cleaning any dust, grease, and similar impurities. Afterwards, moisten the surfaces to improve the adhesion, and then you can proceed with the application.

Application

1. Shake the aerosol for 20 seconds
2. Put the adaptor on the valve
3. Fill the cavity up to 1/3, allowing the foam to expand and fill the rest
4. Repeat shaking the can regularly as you're applying
5. If the cavity hasn't filled entirely and needs another application, allow it to cure and slightly moisten it
6. Proceed to apply a second load of expanding foam

Limitations and Notes

• Do not apply this product if the temperature isn't between 5°C and 35°C
