Features & Benefits

• Versatile Application: Ideal as a gap filler and crack filler, expanding efficiently to seal gaps and cavities.
• Excellent Adhesion: Bonds strongly to various building materials for durable insulation.
• High Yield: Expands significantly (varies with temperature and humidity).
• Moisture and Mold Resistance: Functions effectively as a waterproofing sealant, preventing moisture and mold growth.
• Paintable: Once cured, can be overpainted with water-based paints for seamless visual integration.
  

Application Areas

• Electrical and Plumbing Penetrations: Effectively insulates and seals around electrical outlets and plumbing systems.
• Window & Door Frames: Reliable window door foam for insulating frames and enhancing thermal efficiency.
• General Construction: Firestop foam suitable for sealing gaps, joints, cavities, and penetrations in walls, ceilings, and floors.

How to Use

• Safety Precautions: Contains Diphenylmethane-4,4'-Diisocyanate. Use protective gloves, clothing, and ensure adequate ventilation.
• Surface Preparation: Ensure substrates are clean, dry, and free from contaminants. Slightly moisten surfaces to improve adhesion.
• Product Preparation: If the can is too cold or hot, bring it to room temperature. The optimal can temperature is 68°F (20°C).
• Application: Shake the can vigorously at least 20 times. Invert the can, attach straw firmly, and dispense foam slowly from bottom to top without completely filling gaps, as foam will expand.
• Finishing: Foam is tack-free within 6±3 minutes, fully cures in 24 hours. After curing, trim excess foam and paint or plaster to protect from UV exposure.
