Fire-resistant polyurethane foam sealant for joints.

**Application Instructions:**
**Surface Preparation:**
Ensure that the surfaces to be sealed are clean, dry, and free from dust, grease, or any contaminants. For best results, pre-clean with an appropriate cleaner.
**Application Method:**
Shake the aerosol can well before use. Hold the can upright and apply the foam into the joint or gap, filling it approximately 50-70% full to allow for expansion. Ensure a uniform application for effective sealing.
**Curing Time:**
Allow the foam to cure fully, which typically takes about 24 hours, depending on ambient temperature and humidity.
**Post-application Treatment:**
Once cured, the foam can be cut or trimmed as required for finishing. It is recommended to cover the foam with a suitable finish to protect it from UV exposure if used in exterior applications.
