Clearout Deal

This item is final sale and not returnable

[This review was collected as part of a promotion.] I have been using Great Stuff (awesome name BTW) for years. Here is my take on it.

Prepare your surface carefully. Clean, dry, non-oily, etc.
Disposable gloves highly recommended
Super sticky when wet
Go s-l-o-w, what seems like a little expands 3 to 5 times
Once dry, the foam hardens, yet is still a bit soft.
For my application, I carve the foam with a long-bladed exacto knife. The sharper and thinner, the better.
For my application, I applied silicone caulk to upper edges and recently-revealed air pockets. This is to create a smooth, water-shedding surface.
Finally, allow caulk to dry and spray paint with enamel paint.

For any exterior application, painting is required. The suns' rays will deteriorate and oxidize the surface. So paint must be applied if item is outdoors.

There is quite a bit of material in one can. I would estimate approximately 1.5 cu. ft. of cured foam if you were to use it all at one go.

By the way. You must use it all, or toss the unused portion, since the liquid foam inside the long applicator nozzle will dry and harden, making any future uses impossible.

Works great! Convenient, easy, safe, affordable.

[This review was collected as part of a promotion.] Great Stuff expanding foam when used appropriately, does a fantastic job. Wearing gloves, safety glasses and a mask I was surprised at how easy it was to apply right where I needed it. It flows out like whipped cream, and the dispenser straw makes it easy to aim. I took my time and applied it slowly and evenly, don`t over fill, it expands as it cures. When dry it forms a permanent, weather and insect tight seal. You can cut or sand any excess, then paint or stain if you wish.
Dow claims one 12oz can equals 19 tubes of caulk. They both have their uses, but I would use the foam seal more for unseen areas.
My picture shows a gap above a basement window that was open to the outside. I applied the foam inside and it expanded out through the crack, a complete seal. The inside area was small, and I didn`t really notice a smell, and the outside was no problem either. If you buy it for a particular job, look around for any other places you may need it. This is a one shot deal, as the can and applicator seal themselves shut as it dries.
This was a very positive experience, from a product I had doubts about.

Great Stuff...but read the directions please.

I used this to make fake hot coals for my fireplace for Halloween. It did just what I wanted. Dried nicely and painted easily. I'm using it to make a witches cauldron fire and potion for front yard.

Wear gloves! Your skin will thank you. I had to use a Ped Egg to buff it off my skin :(

Great for crafts

[This review was collected as part of a promotion.] I used it to fill a small gap around my storm door frame. I didn't realize how much it would expand. I left the excess for this review, but I intend to cut the excess away with a razor. It dries quickly. It seemed to have dried in about an hour or two. WEAR GLOVES and protect your furniture or anything close that could be damaged. After you're done using it, it will continue to push the product though the stem attachment so be sure to place it on top of something to catch it as it falls. Works for its intended purpose.

Expands!!

[This review was collected as part of a promotion.] Great Stuff really is great for sealing small gaps and cracks around the house. I have used it to seal gaps around pipes, door frames, etc. It can be messy, so be sure to use gloves and have a rag handy. Its really simple to use - attach the straw, shake, turn the can upside down, and fill the gap or crack. It expands a lot, so be conservative when applying. If you overfill, wait until it's dry and cut the excess away with a knife. A utility or serrated knife works well. After it's dry, it can be sanded or even painted, and it's water resistant and airtight. Definitely a great product to have in your home owner's maintenance arsenal.

Works Great

[This review was collected as part of a promotion.] I used to fill cracks in a number of areas. I included a picture of a filled crack between my driveway and carport, (I'm going to use a simple dollar store razor to trim it.) This stuff works great, like the name says but it can be messy. Make sure you use plastic gloves when you use to avoid getting it on your hands because it can be challenging to get off.

Can't beat it for filling cracks

[This review was collected as part of a promotion.] Great Stuff products are always reliable. High quality. Do what they say they're going to do. The gaps & cracks version is no different. This version will fill larger gaps and cracks up to 1" wide. A little goes a long way. If you do overfill, let it dry and then trim with a razor blade or serrated knife. Make sure to pay attention to the date on the bottom of the can, as it dispenses best when used by that date. Can is 12 ounces. 8" tall.

Great product! Great Stuff!

[This review was collected as part of a promotion.] My husband used this to fill a small hole by our water spout... did ok he says. Good to patch things until you can fix it with mortar. He says it is a good thing to have in hand when you need a quick fix.

Good for Cracks

[This review was collected as part of a promotion.] I used the foam sealant to DIY a repair job around the house. The nozzle for the foam was too big for the space that and I ended up using a putty knife to squeeze the foam between the gaps. I'll have to watch this joint over time to see if it will create an impermeable seal. If it works I'll only have to use this once a year at best.

Wait and see

I tried multiple Great Stuff cans. the fireblocker pro cans with the purchased gun and the regular gaps and cracks cans with the old and new straws. All the products are flawed. they are just not reliable enough to make it worth the cost. I returned the fireblock cans as they were useless, i have 4 gaps and cracks cans, 2 worked well but leave a significant amount of product in the cans. what an expensive waste of product. all the air or aerosol comes out and your left with half a can you can use as a paperweight I guess. there is a reason they keep changing the dispersal system and updating the straws as they simply do not provide a consistent way to use the product. one can blew up in my face while trying to fix the new straw system they use. very close to getting in my eyes what a mess. use safety glasses and gloves of course i was extremely lucky i wasn't injured. While some cans worked I am not buying anymore, its too unreliable going to try another brand.

Messy and Unreliable Product
