Rated 4.6 out of 5 by 32 reviewers.
Rated 5.0 out of 5.0 by Better than expected! Bought this foam to seal up where suspected mice were getting in... Sealed GREAT and no more mice! March 25, 2015
Rated 5.0 out of 5.0 by A Must Have All the previous positive reviews are absolutely right, the Great Stuff Pro line is outstanding. You have much better control and one can sealed a 2500 sq ft house! I like the can will last up to thirty (30) days as long as you leave attached to the gun; make sure get the cleaner, its a MUST have. I will never go back to can and straw stuff; to make this system prefect, the Dow Company needs to offer a shorter can that you can maneuver in tight quarters; nonetheless, this is a great system and a must have tool for your tool box, you will not be disappointed November 2, 2014
Rated 4.0 out of 5.0 by Goes A Long Way This foam/gun system allows one to start and stop unlike the typical can with a plastic tube where one often does not get the complete contents out of the can since the tube clogs. The larger can also permits a greater coverage area. March 10, 2015
Rated 3.0 out of 5.0 by Much better than the one-time use cans I love the fact that you can use just some of the can and get back to it days latter and it is still good. Pressure seems low in these cans. Also the can is too long, which makes it hard or impossible to reach some places, like rim-joist. I wish developers would use their products before selling them, so they could iron out problems like I just described. Over all good product, gets the job done (where my spray foam gun fits) very good. I would still buy more. October 7, 2014
Rated 5.0 out of 5.0 by Pro Formula is Better than Regular Great Stuff This is not just the regular Great Stuff, this is a completely different formula. It sets up in minutes, not hours, and you seem to get a lot more per can than the direct ounce comparison would net. I can go farther with one 24 ounce can of Great Stuff Pro than I can go with two 16 ounce cans of regular Great Stuff. I don't know why, but that is what I have been experiencing. Plus it expands most of the way right off the bat, so what you see is what you get none of the half filling the cavity and hoping/waiting that it will expand correctly. I had always previously just used the regular cans of material, due to them being cheaper per ounce, until I needed to seal against a ceiling. Normal cans don't go "up." (I tried using plastic tubing on straws but they would flow unbearably slow through the tubing. Works ok for a one time deal.) I will never go back to the normal Great Stuff cans. If you don't want to buy the gun, you can find the Pro formula in straw cans. I normally don't write reviews, but this product has truely exceeded my expectations. October 17, 2012
Rated 5.0 out of 5.0 by Does the job! Works great with the pro 14 gun. Not much waste at all. March 3, 2015
Rated 4.0 out of 5.0 by Cost per use makes this the winner Of course this is more per ounce than the 20 ounce "grenade" cans ( pull pin thrown into wall and run installation) but if you want to control the size of the bead and actually put foam only on the project ( not your hair and arms and any other surface in a 3' radius) then spend the extra money for this system. Cans last for 30 days on gun you can pinpoint place product and no more trying to recut the straw and losing a 1/2 can of foam because the little plastic nozzle broke. December 18, 2011
Rated 5.0 out of 5.0 by Great product If you have a lot of insulating of cracks, holes, around doors and windows, etc. This is a great product. It costs less in the long run, even if you have to buy the applicator gun the first time. Way better control over the spray than the small DIY consumer based cans. February 17, 2015
