[This review was collected as part of a promotion.] This Great Stuff big gap filler is indeed great stuff. It was easy to use and did a great job of filling the big gaps in my hunting stand. It helps keep the wind out. It applied easily and with no trouble. I was able to quickly and easily seal up all of the large gaps in my hunting stand.

Great stuff! Literally.

Dupont

[This review was collected as part of a promotion.] I used this for a couple of different areas. One being gaps between the rock part of our house and the siding and then other for holes that cables pass through into the house from the attic. I was most worried about the holes in the house because they were in the ceiling and I didn't want the filler to fall down onto the carpet. Thankfully this stuff sticks where you spray it with nothing falling down. I was able to fill some pretty large gaps and it trims down nicely once it has hardened.

Fills Great

[This review was collected as part of a promotion.] This stuff really does the job of filling gaps and cracks.  It's easy to use, just read the directions, and I recommend wearing gloves.  The applicator makes it easy to apply, wait for it to expand, dry, then trim if needed.  This works great, and really made quick work of a few openings that needed to be closed up on my house.

Great gap filler!

[This review was collected as part of a promotion.] I am very impressed with this gap filler. It does exactly what it says it should do, fill big gaps. It expands rather fast and does not take long to dry. A piece of advice is to not touch it on your bare skin as it will stick, and it is really sticky. Once this big gap filler is about dry it is easy to cut any excess off with a knife. I am so pleased with this filler; I would absolutely recommend it to anyone who is looking to fill a gap big or little as you will not be disappointed with this.

Awesome

[This review was collected as part of a promotion.] The GREAT STUFF SMART DISPENSER Big Gap Filler is dependable and convenient. The product is easy to dispense, and the instructions available on label are throughly written. The applied product stays in tact and in place. The process from start to finish was simple and productive. GREAT STUFF SMART DISPENSER Big Gap Filler is of quality and reliable.

Simply reliable!

[This review was collected as part of a promotion.] I have no experience with this type of product but I wanted to try a little diy on some gaps to save energy. I was nervous that I would mess up the application but I followed the directions and found, to my surprise, that I was able to apply the product in a precise manner. It was much easier than I thought it would be and it filled up the gaps just where I needed it. I'm happy to say it was a success!

Works perfectly

[This review was collected as part of a promotion.] I got this can of Great Stuff Big Gap Filler a couple of weeks ago and it works great. I filled in some cracks in my drywall  and my front steps were loose it works temporarily to fix the steps till I get some longer screws. I got some on my hands but I was able to wash it off.  I would recommend this to anyone.

Works great!

[This review was collected as part of a promotion.] I had a home project of renovating the kitchen sink and put in new plumbing, I had some gaping around the pipes and do not want mice to find there way in. I used my Great stuff gap filler and was very pleased with how well i was able to get precision application thanks to the dispencer. The gap filled in perfectly with little effort. I will use this again!

Fills in very well!

[This review was collected as part of a promotion.] Big Gap Filler is the best! I've used this product in a couple of different areas at my house, outside to fill air gaps by pipe entry, and under the sink similarly around the pipes. A little goes a long way, highly recommend taking it slow when using. Cures nicely and no air leakage left behind. Highly recommended!

Works like a charm!

[This review was collected as part of a promotion.] Tried Great Stuff filler on a bock storage building that needed a little TLC. Used this product to fill in some large cracks in the bock, product works great! Easy and convenient to use and easy clean up.

Great Stuf
