• Apply with Applicator Gun – Use the trigger nozzle to apply the foam, filling the gap approximately 30‑50% full.
• Cure Time – Foam will form a skin in minutes, with full curing typically taking 24 hrs.
• Finish – Once fully cured, the foam can be trimmed, sanded, or plastered over to achieve a clean, finished look. For external use, apply a protective coating to prevent UV degradation.
