Kraken Bond Gaps & Cracks Expanding Foam Sealant - (2x24oz) High Expansion Polyurethane Spray Foam for Window & Door, Straw Use Waterproof High Yield Gap Filler - 2 Pack

I've used Kraken Bond Gap Filler before to seal up gaps in my home and this stuff works great!For example, I used it to fill a small gap around my outside dryer outlet. Somehow, my builder or the folks who owned my home before me, overlooked the gap that let in outside air. I used a bit of this spray foam and it sealed the gap instantly!I ordered this round of Kraken Gap Filler to fill a few small gaps around my front porch where chipmunks burrowed. I managed to trap and release the chipmunks, but will use the Kraken foam to fill in the void before covering it up with landscape rocks. Hopefully, those measure are enough to deter rodents from returning.This foam does require temps above 40°F to work properly, so, I'll need to wait for warmer weather.Lastly, I do recommend using disposable gloves when working with this product. There's a good chance you'll end up with a little on your hands, even with the nozzle wand. It's difficult to wash off and probably not the best for direct skin contact.

I got this product to test out because I had a mouse dog a whole through a part of a wall on my back porch. I decided to catch the little sucker and then fill the hole with this. Worked perfectly. I did have and issue with the pump, but after spraying so much, then sitting the bottle down I guess to regroup itself, it worked perfectly and filled the hole just as I needed it too!! The off white substance in the photo was already there, the whiter substance is what came from this bottle. Will continue to fill the gap that goes all the way up from a little piece of wall that I have no clue is there for. Definitely recommend.

Unfortunately, I was dumb and did this during cold weather, even though I kept the cans in a warm place until right before application. Part of the reason why I didn't get the expansion I wanted is likely due to that.However, a similar can from another brand goes for $15-19 so to get two cans for $27 is good. Both cans come with a spray nozzle so it is nice if you have a bigger project, to switch the used nozzle from the first can to the second can and keep the clean second nozzle in reserve.Alternatively, Kraken sells a five pack of their nozzles which is handy if you want to use a little bit at a time and not have to deal with cleaning the nozzle.The reason why this isn't five stars is because I want more info about how much expansion to expect, how many cans per cubic foot-- that sort of thing.I used this same brand and product a few months ago during the summer and got way better expansion. So....just be aware your $ isn't going to go as far unless you really try to warm up the area as much as possible during the expansion time. And do not store this stuff in a place that gets below 41* F. It says on the can that it can affect product quality, which also might be part of the issue since I kept it in my car for the last week since I got it and it was below 41* every night.A few tips:if you're trying to do this during cold weather, have the can be in a warm place (not hot) so that material inside isn't cold. Then set up a space heater a few feet away or hit with a hair dryer on the cool setting, moving around so you don't scorch the foam.Wear gloves and have a paper towel to catch the drips from the nozzle. You might think you won't touch the foam but you will.Likewise, wipe off any that you get on the wall immediately.Reviewing: Kraken Bond Gap Filler Spray Foam Sealant - Polyurethane Expanding Foam Insulation - Gaps & Cracks Foam for Window & Door | 24 Oz. | Pack of 2 $26.99

I never understood why the cans of foam for use with a gun were so much bigger than cans with straws.. For once a company has made a can with a straw the same size as the cans for the gun..This foam is great quality. What's better is I don't need to clean the gun when I'm finished.High quality at a great price.

The size was sufficient for my needs, and the application process was relatively straightforward. However, it's crucial to note that the foam expands quite vigorously, so precision during application is essential to avoid overfilling. Additionally, the canisters are prone to clogging if not used promptly after the initial application, leading to potential waste. While effective for its intended purpose, users should be mindful of the expanding nature of the foam and the need for prompt usage to avoid any complications with the canisters.

I have several cracks between the cinderblocks in my crawlspace where it allows drafts to enter and I was looking for something to fill these up. This product works well. It was super easy to use and expands nicely. It seems thick and sturdy enough that it won't fall apart if it gets wet. The cans are HUGE and one can was enough to do almost all of my crevices. I plan to use the other and head into the attic looking for places to fill. Great deal overall!

I ordered this to fill gaps between the sheetrock and the sill in my garage to prevent drafts and rodents from getting into my garage. However, since I live in Green Bay, Wisconsin, the current temperatures here are not in the range required to apply the foam sealant. The directions on the Kraken Bond Foam Sealant requires an ambient temperature between 41 degrees F to 86 degrees F. I will need to wait for warmer weather to use this product.The two cans are tall (13.5 inches) and hold 24 ounces each, so I think I will have enough for my project when the outside temperatures are warmer.

Yikes, I didn't need so much Kraken but I definitely got it. The cans are way bigger than I was expecting and now I need to find stuff to fill. It is very easy to use, be brave, point and spray and watch it do it's magic. I wanted to seal under a sliding glass door that I think is letting in water. This stuff says waterproof so we shall see. I wanted to use this as a base for now for other sealants after it dries, it was good for getting into the cracks that I can't see.
