Fire-resistant foam sealant for construction joints.

**Application:**
**Surface Preparation:**
Ensure that surfaces are clean, dry, and free from dust, grease, or loose materials prior to application. For best results, remove any existing sealants or paints from the joint area.
**Application Method:**
Apply **NulliFire FS702** using a foam dispensing gun. Insert the nozzle into the joint and fill it evenly. Avoid overfilling, as the foam expands upon curing.
**Curing Time:**
Allow the foam to cure undisturbed for approximately 24 hours, depending on ambient conditions. Ensure proper ventilation during the curing process.
**Post-application Treatment:**
Once cured, the foam can be trimmed or coated with appropriate finishes if required. Ensure that any additional treatments are compatible with polyurethane foam.
