GREAT STUFF™
Gaps & Cracks
Insulating Foam Sealant

THE GAP AND CRACK ATTACKER

All those openings in your home are like tunnels for heat and air conditioning to leak out and any unwanted air to sneak it.

Our GREAT STUFF™ Gaps & Cracks Insulating Foam Sealant attacks air leaks with a vengeance:

  • It sprays right into gaps and cracks up to 1” (25mm) in diameter.
  • It expands to fill the shape of the gaps.
  • It forms a long-lasting, airtight, water-resistant seal.
  • It helps keep insects, moisture/condensation and allergens out.
  • Adheres to wood, metal, masonry, glass and most plastics.
  • You can use it indoors or outdoors.

And it's easy to finish up:

  • It dries rigid and is tack-free within 5-15 minutes.
  • You can scrape away any excess after 8 hours.
  • Foam elasticity allows movement and shifting within a structure.
  • It's cream colored so you can see where it is.
  • You can paint, stain or sand it.
  • It's UL classified.
* 70 ± 5°F and 50 ± 5 % RH, 1 inch bead diameter, 6 inch length.
* Trims in one hour.
Cure rate is dependent on temperature, humidity, and size of foam bead.
