🦍 Seal it like a pro—no gaps, no worries, just Gorilla power!
Gorilla Heavy Duty Expanding Foam is a versatile polyurethane foam designed to fill and seal gaps up to 2.5cm. It cures quickly with a tack-free surface in 8-12 minutes and can be trimmed after 45 minutes. Suitable for indoor and outdoor use on multiple materials including PVC, brick, wood, and metal, it provides a durable, water-resistant, and pest-proof seal with no shrinkage. For outdoor applications, painting the cured foam prevents discoloration from sunlight exposure.

EAsy to use and does what it’s meant to do.

Does the job
Expands and covers well. Dries quickly. Make sure you shake well before use so aerosol does not escape without releasing foam.

Messy/nozzle useless.
Nozzle is very ineffective and doesn’t stay in place making the whole process very messy. Have used expanding foam in the past without any problems. Having said that, the foam that I did manage to squirt in the gap has set and done the job. Just need to trim excess blobs.
