Great value and that's about it
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!

Works great
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.

Dont forget your gloves
Used this to seal up my garage. You have to use it quickly and all at once time. Have all your seal jobs ready because u can not save your can because it hardens quickly. definitely USE GLOVES AND EYE COVER. SOME CANS DONT EMPTY ALL THE WAY. works well.

Worked as advertised
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.

Works great
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.

Really messy
Very messy product. I am very glad I used gloves as recommended. I chose this product because it said for large gaps, was not very effective and dripped all over the place. Two huge drawback were 1. the foam kept coming out even after I had stopped pressing the nozzle, and 2 you cannot reuse the straw more than once so you better finish an entire can because what you do not use will be wasted unless they start sending extra straws with.
