GREAT STUFF Gaps & Cracks

works great weather durability great in all seasons [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.

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.

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.

Work great. Just be sure to clean the plastic straw right away if you don't use the entire can. [This review was collected as part of a promotion.]

It works. Expands as it should. But if you want to use it again...you better immediately clean ALL the tubing! Which isn't easy!

Got me a Refund

Great Price for Value. Be careful to not use too much in a tight spot, it expands very slowly. I used in a metal building to close up some gaps to keep very small critters from coming in and as I sprayed, it was very thin, so I sprayed a little extra - well - it took time and boy did it expand. If you use this, make sure it has room to expand 2-3x what you sprayed.

Once you start using this stuff, it just keeps on coming, so don't plan on taking a break for lunch or finishing the job tomorrow using the same can. Also don't even think about getting it on your hands, clothes, finish work or anything you don't want to wear it forever. Clean up is difficult to impossible.

I used this product to fill some holes in my fence posts from those lovely boring carpenter bees. In a day or so I plan to cut the exces off, sand down smooth and go over with a solid stain. DO NOT, repeat DO NOT get this stuff on your hands! I made the mistake of not wearing gloves and it dried like super glue/concrete on my right hand. I tried isopropyl alcohol, acetone, dawn soap, even olive oil and lotion. Nothing gets it off your skin.
