Common Substrates:

• Vinyl window and door frames
• Wood frames and framing
• Aluminum and metal surfaces
• OSB and plywood sheathing
• Concrete and masonry (with proper priming)

Note: Surfaces should be clean, dry, and free from dust, oil, or release agents for optimal adhesion.

• Prep Area:
  • Ensure surfaces are clean and dry
  • Shake can vigorously for 60 seconds before use
• Attach Can to Gun:
  • Screw the can onto the gun (do not overtighten)
  • Open the valve on the back of the gun to begin use
• Apply Foam:
  • Gently pull the trigger to dispense foam
  • Fill gaps approximately 1/3 full—foam will expand
  • Adjust bead size using the flow control knob
• Curing:
  • Tack-free in 3–10 minutes
  • Trimmable within 60 minutes
  • Fully cured in 8–12 hours at 70°F / 50% RH
• After Use:
  • Close the gun’s valve to preserve can pressure for up to 30 days
  • Wipe external parts with GREAT STUFF™ Foam Cleaner for daily cleaning
  • For long-term storage, remove can and flush gun internally using cleaner
• Storage:
  • Store upright in a cool, dry place
  • Do not expose cans to temperatures above 120°F (49°C)
• Safety Tips:
  • Use in a well-ventilated area
  • Wear gloves, long sleeves, and safety glasses
  • Keep away from open flames and ignition sources
  • Do not use in enclosed or non-ventilated voids
