GREAT STUFF Big Gap Filler | Insulating Foam Sealant, 12 oz. – Cream (8 Pack)

This insulating foam sealant is a great value—plain and simple. It does the job well, but there are a few things to keep in mind. If you’re filling a hole facing down, make sure it’s no wider than about 1 inch; otherwise, the foam might sag before it hardens. A little trick is to place some cardboard or another backing in front of the hole to keep it in place while it sets.Overall, it’s the best value I’ve found for bulk foam sealant. It’s effective, easy to work with, and perfect for sealing gaps and cracks around the house. Just follow a few tips, and you’re good to go!

The perfect product for the job I had at a great price.

I bought this to insulate a storage building I built for my wife. I had several cans of regular foam insulation but they wouldn't fill some large spaces without two or more applications. This applicator filled the gaps with one pass making the application quicker and neater.

this was a good deal, but two of the cans did not seem to work properly. the foam did not expand.

Great stuff

Works great. It shoud be noted you must use the whole can because the spray nozzle can only be used once. Also it goes a lot futher then I expected. I only had to use half of what I thought.

Used it to seal off air-gaps in my new metal building. Worked very well in filling the voids that every Mississippi wasp would love to use to enter my shop! Went further than expected so ended up with a couple extra cans to use in other outbuildings.

I bought the case of these for sealing up an old barn. Over half of these did not expel ANY foam. They were already rock hard. I contacted the seller several times and nobody contacted me back about replacements or refunds. Waste of money and time.
