GREAT STUFF Big Gap Filler, 12 Oz

I'm a single mom and over the years, I've taught myself to take care of as many projects projects as I can in order to save money, learn to take care of things myself and to teach my son car and home maintenance. When this product became available, I ordered it with a specific project in mind...I had no idea how addicting it was going to be!! I have been using it EVERYWHERE!! I have used it around pipes,, both indoor and outdoor, around my dryer vent to prevent critters from getting in through the gaps, I used it around my shed doors, all around the perimeter of my house where I saw gaps. I literally went "looking" for areas to use this product - I wanted to use the entire can at once because I felt using it at a later time might not be as easy as the first, especially once it has been exposed to air.

I bought a house 11 years ago. Ever since then I had gotten water in the basement when it rained heavy. I decided to try filling the area with Big gap filler. I finally have a dry basement! It filled the area up against the foundation and stopped the leak! I'm super happy it worked so well. Saved me a fortune.

I found a gap under my bathroom sink. When we bought our house it had a full remodel already. We had started to notice some less than perfect fixes in places you don't always look like under sinks and things. This was hidden behind a cabinet with drawers. But when I looked for my makeup I spotted it. It was a rather large gap around the sink pipes. And as anyone knows a gap in wallboard can mean escaping heat and entering cold air. So i decided this was a great place to give it a try. This stuff worked AMAZINGLY I just kept spraying a bit at a time till I saw it rising slowly out of the hole. It expanded to fill the gap well. I felt no more air coming from the hole. I was wondering if it was a one time use can or if it could be used again. Because there was quite a lot left in the can. This stuff quickly dried in the hose. And I didn't think it would be usable again. But I found some hints online that said to lightly tug at the dried material at the end of the tube. And it slid right out. Clean tube ready for use again. This stuff is a lifesaver as I do not know how to repair Sheetrock. And honestly it is out of sight so a beauty fix isn't necessary. I highly recommend this stuff for weather proofing gaps holes and small spaces.

This gap filler works really well for drafty windows, outside spots where water can get in and many other uses. I put some around my windows and outside water spigots. You only need a small amount because it enlarges the amount approximately 3 times. Great stuff Gap Filler turns into a dry foam and keeps out water and air. I also used it at the base of my walls in my garage to keep out cold air in the winter. Try this and it should reduce electric bills and you will save yourself some money.

Works perfect! I got this to use in our DIY bathroom remodel. It was used to fill in areas around the under sink pipes where there was some openings to the wall, in addition to sealing the space around a door leading to the exterior. Didn't take too long to dry and worked out for what we needed.

Used this gap filler in our attic, which had spots where the sun shines through. The before/after pictures attached show how well this gap filler seals the gaps. I made no effort to make it neat; I let the overspray hang and/or fall off. However, for areas that get more eyes/need to be more attractive, you can easily contain where the spray hits with the nice plastic tube that the spray comes out of (or literally cut or saw off the excess after it has dried). One tip I'd offer for any other novice gap filler sprayers out there: dust the area first or the spray will just fall off with the dust and create waste. Also, in an effort to try to speed up the process I sprayed too much in an area before moving on, and the result was that most of the spray just fell off. The spray was more likely to stay where I wanted it to if I sprayed a little to start covering an area and I went back to that same area to layer on the spray one or more times later (it stuck to itself better after waiting a bit, perhaps after it congealed a little). I made long, steady left-to-right motions with the spray nozzle, and that seemed to give the spray enough time to gel for multiple layers/sections with wider gaps to fill. A single can covered a whole 3-4 foot section of gap with very generous spraying. I could have used it in more areas but that was all I needed for now. The directions say that it only lasts for about a month, so I figured I'd use it all on whatever I needed done so it didn't harden in the can and just go to waste. Very happy with how easy this product was to use (and to clean up afterwards including on my hands with just regular soap and water!).

This works to fill large gaps but be prepared for a mess. It works the same as the other Great Stuff formulas by expanding to fill gaps, but it drips if it's not on a flat surface. You have to use acetone to clean up until it has hardened (cured). After it has cured, you can sand it or use a serrated blade to remove any excess foam. And be prepared to lose a lot of foam if you don't have a large job because once the foam cures in the dispensing tube, you can't use it any more. It does what it's supposed to do well, though.

This is a very useful product. Perfect replacement for when the alternate would be a lot of calk. I used it to fill gaps in windows and was able to then sand and paint over it. I have used it inside the house so I am not sure if this can be used outside and will withstand extreme heat, rain or cold. Straw makes it easy to get to hard to reach surfaces. One thing I would like to mention is that the foam expands quickly and becomes big so this product is not meant to be used to fill small cracks.

The Great Stuff Big Gap filler does Just what it says it does! It fills the gaps! This can has filled the crap under my front door with ease and I've also been able to use it to fill the spaces around the lighting fixture holes in my garage and other various gaps to the outside of the house. It has surprised me how versatile this has been. Super easy to use and a little bit goes a long way.

I had major plumbing work done, and, afterwards, needed to fill a 1-1/2" wide x 3" deep hole that the plumbers drilled from my basement subfloor to my living room in order to re-route broken heating pipes; the new pipes were then re-re-routed, when the major repair was completed, thus leaving the aforementioned hole. I needed a magnifying glass to read the very tiny instructions on the Great Stuff label, but, followed them, exactly. At first, the thinly-threaded stream of spray foam went from the living room straight down to the basement, but, then, I was able to "layer" it, using a circular motion, so that it stayed in the hole, although it left about a 2" wide excess of the stuff along the floor, which I scraped up with a trowel, though it still left some residue. About an hour later, the foam in the hole expanded on both sides of the floor (top of the living room floor through to the basement end), filling it completely, as well as beyond the edges, but, only by a few inches (both sides of the hole are well out of the way of pedestrian visibility and traffic, where aesthetics aren't an issue). After letting it cure for a little over 24 hours, I was able to slice off the excess from the top of the hole in the living room, using a straight edge razor blade (just the razor; no holders, which were too bulky to work around the given space). The dried foam sliced off, easily, and, much to my surprise, the residue that overflowed onto the wood floor, that I couldn't trowel off, peeled off even more easily! I did not bother doing such on the basement (bottom of the hole) side, as it is an unfinished basement, and that area is completely out of sight. I waited another hour or so, just in case the now-leveled foam need further curing (I don't think it was the case, but, I wanted to be sure), and then sanded the foam with 120 grit sandpaper, just to give it a "clean" look. The next day, I wanted to fill a 3" wide x 1/2" deep gash in the ceiling (also due to the plumbing work), but the foam wouldn't go through the straw, so, I removed the straw and the curved end (pops off with a little effort), peeled off the dried foam from the can's top, pushed the dried foam through the straw with a thin dowel, and was able to get a stream going, though, not as thick as when the straw was clean (not sure why; maybe there was more dried foam in the can that I couldn't see). The gash is on the ceiling, so I had to trowel it into place, as well as to prevent it from dripping down onto the floor, of which, the latter, surprisingly, never happened! Again, I waited 24 hours, and was rewarded with a completely filled gash, that went only about half-an-inch beyond the hole in any given direction. Given the angle, slicing the foam to be flush to the ceiling was a bit of a chore, and sanding tended to rip it, but, I managed to smooth it out with a 120 grit sanding block (the kind used for drywall installation). I won't bother staining the floor foam to match the wood (not large enough to be worth the effort, and no one will see it, anyway), but, the ceiling foam had to be covered with drywall mud and tape, just to give it more strength (a high-hat light fixture butts right against the gash; it wasn't affected by the foam, but, needs the structural support that the foam, alone, won't give). The mud adhered to the foam fairly well, but, needed a little extra troweling to keep it on. I ended up throwing away a barely-used can (I doubt that I used more than 25% of it), because, after the ceiling repair, it was totally clogged. Read the directions, thoroughly, before using it, and try to line-up as many gap areas as you can (under sinks; near basement windows; wherever extra insulation is needed; etc) so that you use as much of the product as possible, lest the remainder become unusable, as happened to me (par for the course for the product); make sure to wear gloves (I used cheap, disposable, clear, plastic, ones, and they worked out just fine), and have at it! You may need to trowel the product into the gaps/holes, but, leave it alone after doing so, and you'll be rewarded in as little as an hour. Many filled areas, such as under sinks, do not need to be sliced flush to the wall, so, if it's out-of-sight, don't bother! I took off a star only because of the waste. But, what I was able to use worked out great for me!
