Instructions for use:

1. Preparation :
   • Wear gloves and safety glasses.
   • Do not apply in confined spaces. It is important to ventilate the areas well during application and curing.
   • Warm cold bombs with lukewarm water. Bombs cannot be heated above 30°C. Bombs that are too hot must be cooled with water. Shake the bomb to reach the required temperature more quickly.
   • The surfaces must be free of dust and grease. Always pre-moisten the surfaces, as the foam expands due to moisture.
   • Shake the aerosol can vigorously at least 20 times.
   • Hold the aerosol can upright while screwing on the NBS gun. Move the gun to the aerosol can, holding the handle with one hand and screwing the can on with the other. Do not tilt the can while screwing.
2. Laid :
   • Hold the can upside down when extruding the foam. Adjust the flow rate by operating the adjustment screw and the trigger or with the adapter.
   • Fill joints and cavities to 60-70%.
   • For wider joints, apply in several coats and moisten between coats.
   • After use, return the can to a vertical position using the gun or adapter.
3. Cleaning:
   • Cleaning of fresh foam with PU Foam & Gun Cleaner . Cleaning of hardened foam with Parafoam Remover.

Packaging:

• 750 ml spray can

FAQ - Frequently Asked Questions

1. What is the difference between a sprayable foam and a nozzle foam?
   Sprayable foam allows for much more precise flow control, a better finish, and less product waste. It is ideal for professional or heavy-duty use.
2. Is Parafoam NBS moisture resistant?
   Yes, once hardened, it is resistant to moisture, but it must be protected from UV rays (paint, coating, sealant).
3. Can the foam be painted after application?
   Yes, after complete hardening, the foam can be painted, coated or covered without any problem.
4. Is it suitable for soundproofing?
   Yes, thanks to its closed-cell structure, Parafoam NBS effectively contributes to the reduction of airborne noise.
5. Is the foam fireproof?
   Parafoam NBS is not a fire-resistant foam. For specific fire resistance requirements, it is recommended to use a PU foam certified for fire resistance (RF).
6. What is the shelf life?
   Generally, up to 12 months in its original packaging, stored upright in a dry and cool place.
7. Can the spray can be reused after opening?
   Yes, provided the gun remains screwed onto the can and the gun is cleaned after use. This allows for subsequent reuse without clogging.
