GREAT STUFF Big Gap Filler 20-fl oz Spray Foam Insulation

  • GREAT STUFF Big Gap Filler insulating foam sealant offers the same benefits as GREAT STUFF Gaps and Cracks, but fills gaps larger than 1-in
  • It's perfect for creating larger weather-tight seals to stop drafts and keep critters out
  • Like all GREAT STUFF products, it's airtight, paintable, stainable, and sandable
  • Polyurethane based and perfect for a variety of materials including wood, drywall, metal, masonry, glass, and most plastics
  • Interior or exterior use, cream colored foam cures rigid
  • Foam elasticity allows for movement and shifting within a structure
  • Tack free in 6 minutes; can be trimmed in 30 minutes
  • One 20-oz can is the equivalent of 30 tubes of caulk
