🛠️ How to Use
  1. Ensure the application surface is clean, dry, and free from dust, grease, or loose particles.
  2. Lightly moisten the surface and gap with water to promote adhesion and curing.
  3. Shake the canister vigorously for at least 30 seconds before use.
  4. Attach the application gun or straw and apply the foam in a continuous, controlled motion, filling the gap approximately 50% full to allow for expansion.
  5. Allow the foam to fully cure (typically 1–2 hours for surface cure, 24 hours for full cure) before trimming or painting over the excess.
  6. Trim any excess cured foam with a sharp knife and finish as required.
⚠️
Safety & Handling Notice

Always wear appropriate personal protective equipment (PPE) including gloves and eye protection during application. Ensure adequate ventilation in the work area. Keep away from open flames during application as the uncured foam may be flammable. Store in a cool, dry place away from direct sunlight and heat sources. Keep out of reach of children.

❓ Frequently Asked Questions
Q What does the "B2" fire rating mean for this PU foam sealant?
The "B2" rating refers to the European fire classification standard EN 13501-1, which classifies building materials based on their reaction to fire. A B2-rated material is considered "normally flammable" but is specifically formulated to resist ignition from small-scale fire sources and limit fire spread, making it significantly safer than standard unrated PU foams in construction environments.
Q Can this foam be used for both interior and exterior applications?
Yes, the B2 Fire-Retardant PU Foam Sealant is suitable for both interior and exterior applications. However, for exterior use, it is recommended to cover or paint the cured foam to protect it from UV exposure and weathering, which can degrade the surface over time.
Q How long does it take for the foam to fully cure?
The surface of the foam typically cures within 1 to 2 hours under normal temperature and humidity conditions. Full mechanical cure, where the foam reaches its maximum strength and can be trimmed or painted, is usually achieved within 24 hours. Higher humidity levels can accelerate the curing process.
Q Is this product safe to use around door and window frames?
Absolutely. This foam is specifically designed as a go-to solution for installing and sealing doors, windows, and other building components. Its fire-retardant properties make it particularly well-suited for these applications, as door and window frames are common pathways for fire and smoke spread in buildings.
Q Does the B2 fire-retardant foam also provide thermal and acoustic insulation?
Yes. In addition to its fire-retardant properties, this PU foam sealant delivers excellent thermal insulation, helping to improve energy efficiency in buildings, as well as acoustic insulation to reduce noise transmission through gaps and joints. It offers a multi-functional solution in a single product.
Q What is the difference between this B2 foam and standard PU foam sealants?
Standard PU foam sealants are not formulated with fire-retardant additives and can contribute to fire spread when exposed to flames. The B2 Fire-Retardant PU Foam contains a specialized formulation that resists ignition from small-scale fire sources, providing a critical safety advantage in construction applications where fire resistance is required by building codes or safety standards.
