GREAT STUFF™ Multipurpose Black Insulating Foam Sealant

GREAT STUFF™ Multipurpose Black

Now with the SMART DISPENSER™!


The Jack Of All Trades

Meet Ole Faithful - it fills unwanted gaps and cracks, can be used across multiple applications, and blends into the surrounding environment. This ready-to-use, minimal expansion polyurethane insulating foam sealant fills, seals and insulates gaps up to 1 inch, expanding to take the shape of gaps and cracks to create a long-lasting, airtight and water-resistant seal.



  • Black in color, blending naturally into the surrounding environment.
  • Multipurpose in function, for both interior and exterior use.
  • Fills, seals and insulates gaps up to 3/4”.
  • Allows cured foam to hide well and not be noticeable in shadows.

It's easy to use because it's:

  • All-direction dispensing.
  • Adheres well to stone, eliminating the need for a caulk adhesive (depending on the project).
  • Adheres well to rock, wood, metal, masonry, glass, and most plastics.
  • Cures quickly 5–15 minutes,1 trims in 60 minutes (moisture-cured).
  • Paintable, stainable, sandable.

170 ± 5°F and 50 ± 5 % RH, 1 inch bead diameter, 6 inch length. Cure rate is dependent on temperature, humidity, and size of foam bead.



No drips, less mess - foam stops where you stop.
Reusable for up to 30 days - use again and again.
Precise, greater control.
