Rated 5.0 out of 5.0 by Greg Great Stuff Usage Tips
In the past 6 months, I have purchased at least 2 cases of this foam. The expansive and sealing properties of this foam are incredible. I've used it to seal up drafty holes in the house, around leaky air ducts and inside new walls to keep moisture and insects on the outside. I've learned a lot about this foam and have some tricks I hope you can use.
ALWAYS shake the can well the first time. The foam really does tend to settle in the can and needs to be remixed for best consistency.
Make sure the trigger is tightly secured. I even check it from time to time as I use it.
Be light on the trigger, especially the first time. There is a lot of pressure in that can and it the foam will escape faster than you'd probably like it too if you squeeze too hard.
Try not to let the foam weigh itself down. It will start to drip and fall if you get too much in one section. That's when things get messy. If you have to, wait for it to start setting up a bit and then spray some more to fill in the remaining gaps.
Get the nozzle as deep into the crack as you can. That way the foam really fills up the void from the inside out.
Once dry, the foam can be cut easily with a sharp knife or razor blade. I have used it as a backing for caulk or even putty before and then sanded and painted over it.
If you don't use the whole can, clean out the nozzle and store it. It can be re-used later.

Rated 1.0 out of 5.0 by Cando Too messy and uncontrollable
Sprays out of can too fast and too powerful causing too much over pour so that it clumps up in places. You cannot apply this stuff evenly making the finish look very ugly. It also doesn't stick to surface fast enough so that it drops off ceiling application and also drips down the wall when applied vertically. As you can see in the picture, this stuff falls off the ceiling before it can be applied. This stuff must be applied only downward if using it too seal along edges and even then it fills up too fast. About all that it is good for is filling up large holes and big cracks. If it came out of the can slow and steady and would stick immediately, it would be a better product.

Think out of the can. I have used this to insulate cold spots in walls where the insulation settled. I drill holes thru the plaster 6-8" apart and squirt foam in til the tone changes. Have plenty of holes drilled and you will never have a partial can. After it is cured use something pointy like a potato peeler to remove excess at hole, fill with spackle lite and touch up paint. I insulated a very cold bathroom that was a porch in a previous life this way.

Rated 4.0 out of 5.0 by paul185 Great product, but...
This gap and crack foam sealant is great! It really does work and seals well from drafts and moisture. I've used it in my basement and outside shed. It's tricky to apply at first, but once you get used to how much comes out and how to apply it it's much easier. Fyi, it does expand about x5 as much as you squeeze out so be aware! They only downside to this product is that it's a single use design. If you've only used half a can, you can't save the rest for another time as the foam expands in the tube and blocks it. But for a one-time projects it's great!

This stuff is great hence the name I worked as a sub contractor for a few years and got enough experience with this product had no issues what so ever a great tip that everyone should know when applying is you can reuse the straw applicator just pour some acetone down the straw wait a few seconds and it eats right through the foam I recommend you do it once your done dont wait too long it only works when its not cured

Before you check out with this product , make sure that the spray tube attached to the can isn't cracked.
The one I bought had half of the part of the tube that attached to the nozzle on the can cracked in a way that I thought it was required to add air to the product as it dispensed. It didn't look like a crack.
But once I started using it, the foam came right out, then I tried to tape up the crack and it worked for a little bit, then the foam started coming out from underneath the spray attachment, Then I tried to use the can like a whipped cream canister with limited results.
I could not finish the job because the tube was inoperable. I believe this is a packaging issue, the spray tube probably got cracked during shipping or stocking since the spray tube is just taped onto the side of the can.
Still very disappointed since the product seems to work, but in the future I'll avoid this brand or package design.

Rated 4.0 out of 5.0 by JimmyDead Definitely works but can is only good for one use.
This did the job I needed it to. It's pretty easy to use, not too messy as long as you're careful and use rubber gloves. You can also shave it down after it's dried if you've used too much.
However, the can is only good for one use, because after the first time, the tube/spray inside gets clogged up. That's probably why it's only $7, but overall, I would use this again.

Great Stuff is a very handy product to have for many DIY projects. I like to keep a can or two on hand for those situations that arise throughout the year. I rated the value as a 4 because it can get costly if you need more than a can or two to tackle a larger project.
