GREAT STUFF Gaps and Cracks 12-oz Straw Indoor Spray Foam Insulation Canister

What Customers Are Saying

Customers overwhelmingly praise this spray foam for effectively sealing gaps, cracks, and holes around windows, doors, and pipes with strong, durable results. Most find it easy to apply, with rapid expansion and fast drying that allows quick trimming. Many appreciate the excellent insulation value and reliable performance across diverse applications. However, reviewers consistently warn that the product cannot be reused once opened as the nozzle clogs quickly, and the foam is very sticky and messy, requiring immediate cleanup and protective gear. A few report defective nozzles or storage-related failures, but overall customers consider it a dependable solution for weatherproofing and sealing tasks.
