Using this specific product

GREAT STUFF (DuPont) GREAT STUFF Big Gap Filler Insulating Foam Sealant is listed here as the Smart Dispenser can version for gaps, pipes, and rim joists. For sealing a joint, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Smart Dispenser can; related versions can use different timing.
  • For gaps, pipes, and rim joists, pay particular attention to joint depth, tooling, ventilation and exposure to water.

How to check readiness

Probe an inconspicuous edge for a continuous skin and follow the stated water-exposure milestone. Tack-free in 5–15 minutes. Trimmable in one hour. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

Surface skin is not the same as through-cure, especially in a deep joint.
