Gorilla 高耐久 拡張フォーム 353ml - 多目的、耐久性、空気、湿気、害虫をシャットアウト | 収縮なし & 最大密閉 | 屋内&屋外用 * 使用

Really great stuff,did exactly what it says and blocked out rain from getting into my hut

Very good. Gorilla products are always good.

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

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

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.
