Great Stuff Smart Dispenser Pestblock is a ready-to-use 12 oz foam sealant designed to block gaps and keep nuisances out of your home. The foam expands up to 1" to conform to irregular openings and creates a durable, airtight seal that can be used on interior and exterior surfaces. The Reusable Smart Dispenser threads securely to the can and can remain attached for up to 30 days for no-drip, controlled dispensing. The foam dries tack-free in about 20 minutes and cures rigid for trimming in approximately 1 hour, allowing you to trim, sand, stain, and paint for a finished look. It bonds to wood, metal, masonry, glass, and most plastics and is recommended for use around PVC pipe penetrations, cable lines, faucet penetrations, attic hatch frames, rim joists, sill plates, and other common entry points. Provides long-lasting sealing performance for home and perimeter applications, with an effectiveness duration listed at 730 days.
