• Flexible, Low-Pressure Polyurethane Foam: Expands just enough to create an effective gasket without warping framing or drywall.
• Durable, Compressible Air Seal: Cures into a soft, flexible seal that accommodates joint movement over time—ideal for pre-drywall sealing.
• Fast Tack & Cure Time: Tack-free in ~8 minutes, fully cured in ~1 hour, accelerating jobsite progress.
• Precision Dispensing Gun: Designed specifically for Gasket Foam, ensuring controlled bead size, cleaner application, and minimal waste.
• Moisture & Mold Resistant: Water-resistant and mold-resistant once cured—suitable for high-humidity environments.
• Paintable and Trimmable: Once cured, foam can be trimmed or painted to match surrounding materials.
• Energy Code Compliance: Helps meet IECC, ENERGY STAR®, and other air sealing standards by reducing air leakage.

• Sealing between top and bottom wall plates and drywall
• Air-sealing around rim joists and wall sheathing
• Creating pre-drywall gaskets in framed construction
• Sealing HVAC, plumbing, and electrical penetrations
• Energy code compliance air sealing during rough-in stage

Common Substrates

• Wood (dimensional lumber, OSB, plywood)
• Drywall (gypsum board)
• Concrete and masonry
• Metal framing (galvanized, steel)
• PVC and other rigid plastics
• Foam board insulation

Note: Always test for adhesion on unusual substrates or in high-moisture environments.

• Surface Preparation
  • Ensure surfaces are clean, dry, and free of oil, dust, or debris. Protect adjacent areas as needed.
• Shake Can Thoroughly
  • Shake the can vigorously for 60 seconds before attaching to the dispensing gun.
• Attach to Gasket Dispensing Gun
  • Screw the can onto the gun securely. Adjust flow control to achieve desired bead size.
• Apply in Continuous Bead
  • Apply a uniform, continuous bead along framing surfaces to form the gasket. Maintain consistent speed and pressure.
• Curing
  • Foam will be tack-free in about 8 minutes. Full cure typically occurs within 60 minutes, depending on temperature and humidity.
• Post-Application
  • Once cured, foam may be trimmed, shaped, or painted. Clean dispensing gun with Great Stuff™ PRO Cleaner immediately after use.
• Storage
  • Store upright in a cool, dry place. Do not expose to temperatures above 120°F or below 40°F.
