How to Use

• Safety Precautions: Contains Diphenylmethane-4,4'-Diisocyanate. Always use protective equipment and maintain good ventilation during application.
• Surface Preparation: Ensure surfaces are dry, clean, and clear of contaminants. Slight moisture improves foam adhesion.
• Preparation: Shake canister vigorously at least 20 times. Optimal application temperature is between 41°F (5°C) and 86°F (30°C), ideal at 68°F (20°C).
• Application: Attach straw, invert canister, and apply black expanding foam from bottom upwards, allowing room for foam expansion.
• Finishing: Foam becomes tack-free within approximately 7±2 minutes, with full curing after 24 hours. Trim and protect with paint or plaster to extend UV resistance.
• Cleaning: Immediately remove uncured foam using Stanley T244 Foam & Gun Cleaner. Cured foam requires mechanical removal.
