16 oz. Big Gap Filler Insulating Spray Foam Sealant with Quick Stop Straw

I had a can of this explode on me this June (not hot out, not cold). I couldn't figure out why the cabinet door wouldn't open in my basement storage area. it took a lot of chipping and prying. The great stuff enveloped all the other stored things around it, costing you money and time. I do not recommend.

I had to cut out some PVC for our tankless water heater and there was a substantial gap. This can filled in the gap and insulated everything behind the pipes couldn't be happier.

unless you plan on throwing your whole hands away, I do not suggest getting it on them. wear gloves. it has been day 2 and I'm still dealing with this stuff not coming off my hands. I should have read instructions and reviews. In addition, you better use all at once. Will definitely dry out.

Filled up my old 1928 fireplace that was letting bugs and cold air into my living room. It didn't have a typical flu and I wouldn't want to burn any wood in it. Once we fill the hole in we spray painted it all black inside so now in the winter and Summers I'll be comfortable

purchase Exterior door exterior door Home Depot and I use great stuff for installation

Works well. Fills and seals gaps

Worked great filling the hole

Great Product. Need to rotate stock better. Great Stuff!!

This 16 oz. Big Gap Filler is really doing a great job. It extends and close the gaps quickly. It is extending and drying really well. I was able to cut the excess foam with a knife. WARNING: Do not touch this stuff with your bare hand it will stick and you gonna have difficult time to remove.

Great Stuff insulating foam has the most reliable and consistent formulas compared to other brands I have tried. Further, they have a foam for just about every situation. The original standard foam "Gaps and Cracks" is probably going to be your number one use type. However, there are times when you have large voids with lengthy areas to bridge. Enter "Big Gap Filler". This expands nearly 5 times the size of the normal foam. I recently bought three varieties of Great Stuff for my Pond Project: Great Stuff Big Gap Filler, Original Gaps and Cracks and Great Stuff Pond and Stone Foam. I was creating a new waterfall. After weeks of arranging rocks up the waterfall course, once satisfied on how the water was flowing, I turned off the waterfall, let the rocks dry then began foaming beginning with big gap filler. I filled the large voids behind the rocks. This would keep the majority of the water from flowing behind the rocks. Next I used the standard foam between the rocks and to "cement" the smaller rocks into place or secure the rocks to the liner. Lastly, I used the pond form over all the other foams and placed it in places I had to disguise liner. I pressed sand into the fresh foam as well. I also used this between my flagstones around the pond, using standard foam and big gap underneath the flagstones to cement them in place on the liner OR close up gaps so that water could not travel beneath them. But this is not all, HD also sells other varieties too. They have a window and door foam which stays soft after it cures. This is important to keep the weight of the house above from pushing into your window or door jambs. They also have fire block foam. This is great where you have penetrations in firewalls (like the wall between your house and garage for instance). They also have foam that is critter resistant to keep bugs or other pest from penetrating openings called Pest Block. This is great around things like spigots on your house that bugs might try to pass from the exterior to the inside of your home. Lastly they have a Multi-Purpose Black foam for indoor or outdoor use good around hardscapes and such (use pond and stone for water features or very wet areas though). With ALL of these foam types, there is major things to remember. Where eye, glove and clothes protection and protect the areas around where you are spraying. The foam is SUPER STICKY and will not easily come off of ANYTHING! Acetone works a LITTLE (and I mean not much at all - but it is better than nothing). If foam drips down while you are spraying - LEAVE IT until it cures. You will make it worse by touching it while wet and easier to remove when cured. Notate all the places you need to foam before you start foaming and prepare ALL the areas before you begin!!!! This is important as once you start, you want to continue until the can is empty. They do have the new nozzles that let you turn off and on the foam from leaking out the straw in between spraying two or more areas, but remember, this tends to be difficult. If you are trying to reach into long spaces, suggest you find some long straws or tubing that you can fix to the straw BEFORE BEGINNING. Do deep filling places FIRST. Save easy surface gaps for the end of the can. This is because the flow is much bigger in the beginning and gets less and less over the life of the can. Lastly, if you have left overs, you can close the straw and hope for the best. The can even states, expect only one use. I have cut off the end of the straw and have got to use the rest of the can, but for the most part, it's a one use can. Jeff
