Good Dispenser

4 years ago
[This review was collected as part of a promotion.] We really like Great Stuff products and use them quite a bit in our business. This particular one is easy to operate and allows you to get into those small cracks that are hard to reach.

Yes, I recommend this product.

It's actually reusable!!!!!

4 years ago
[This review was collected as part of a promotion.] First off, this spray foam is great. As you can see in the included photo, it takes seconds to fill cracks. I've been using the spray foam for years. It's a lot easier and quicker than using caulking. Once it dies, you can cut it, sand it and paint it so no one knows you used the foam. It creates an air tight seal. I'm doing outside remodeling and I'm finding cracks and holes everywhere. I just grab my can of spray foam and it's filled in in a second. The biggest pro about this particular spray foam is the fact that it's reusable. I couldn't tell you how many cans of spray foam that were thrown away still half full because once the foam dried in the straw, it closed that straw permanently and there's no way to clear the dried foam from the straw. With this particular product, the foam won't dry in the straw and you can reuse the straw and there's no more waste. I definitely recommend this product to anyone that needs holes and cracks filled in around their house. It's perfect.

Yes, I recommend this product.

Works well!

4 years ago
[This review was collected as part of a promotion.] Used this in-between some open crack areas where my awning meets the roof. It would always drip right in front of the door when it rained. This stuff is so easy to apply and worked to close all gaps instantly. Very happy with the results.

Yes, I recommend this product.

MUCH better design

4 years ago
[This review was collected as part of a promotion.] With the new dispenser, I've been able to use this on my home and my toy hauler to seal things up before the winter. The foam expands as intended but with less mess after the fact. I've been happy thus far with the sealing part and checked my camper probably 3-4 weeks later and no signs of mice yet (wahoo!). It's parked behind our shop next to a field so that's a good sign to me! I haven't had any problems yet but I can see that the nozzle plastic piece could be easily broken. However, for the price point, it wouldn't be the end of the world. Would definitely buy this again.

Yes, I recommend this product.
