GREAT STUFF Big Gap Filler, 12 Oz

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.

I have used Great Stuff products for years for different home purposes. Recently my daughter bought a huge Farmhouse home with wrap around porch and plenty of nooks and crannies allowing air to blow inside. Great Stuff Big Gap Filler worked great to fill in those large gabs. This product is easy to work with and will save her money on her heating bill. I highly recommend this product !

I used this to fill some gaps around a door jamb. It worked perfectly. The nozzle was trouble free, and the foam dried in the expected time. This is not the type of product I use often, but when I do need it: I see no reason I would not use this brand again.

I was afford the opportunity to try Great Stuff Big Gap Filler. We recently had a bad leak in tbe bathroom we had to rear our the floor to replace pipes and new toliet. We had a gap between the floor and wall. I used the product and it was so perfect for my emergency project! I'm so glad for this opportunity it can right on time.

If you have cracks that need to be filled this is GREAT STUFF! Seals bugs out, unwanted air flow or just gaps that need to be sealed. This is so easy to use but you have to use the entire can at one time. It is sticky at first but once it dries you can do anything you want to shape for esthetics.
