  • Quality product
Style: Pest Block 12oz Size: 2 Pack
The foam applies easily and simply. As with other foam products, you learn not to overdo it as the foam expands before hardening. Also, don't touch it, because it will also adhere to your skin and is hard to remove. Product was shipped promptly and the can and spray nozzle are well designed.

  • Used all 12 to block mice running behind my apartment walls
Style: Pest Block 12oz Size: 12 Pack
I could hear mice running from inside my walls in my apartment. I could hear them scurrying around especally at night. Kept banging the walls to scare them away but kept coming back. Got fed up and drilled holes inside the lower part of my walls throughout my apartment, then I pumped all the foam inside it filling in the gaps. I think it worked. Haven't heard anything yet. And the foam contains mice repellent so they won't chew their way thru. Hope it lasts. ... show more

  • Lots of foam
Style: Gap Filler 25.3oz Size: 2 Pack
Nice large cans of foam. Sets up pretty quickly, no holes/voids at all. I think this is the second time to order this brand, and there's more in my cart.

  • Effective… But the smell!
Style: Pest Block 12oz Size: 1 Pack
This is a fine expanding foam and probably good barrier for pests… but let me warn you: the smell is unbearable. DO NOT manipulate without gloves, and DO NOT inject the foam near living spaces.

  • Perfect for sealing cracks and filling gaps
Style: Gap Filler 12oz Size: 1 Pack
Our new to us home has 70 year old windows in the basement and they needed to be sealed around the edges so I got this in hopes it would do the trick; it absolutely did! I was also able to use this to seal the back door that hasn't been square in the door frame in years, and all the old coaxial cable holes in the floors and walls. I especially appreciate being able to cut, sand and shape it the way I want it once it hardens. ... show more

  • Wasted full can when it quit working after 6" of use!
Style: Window & Door 29oz Size: 1 Pack
can gave up after 6". This was not a stop and go but a continuous spray that quit working after 6". Probably a good product, but useless if you pay for a full can and have to throw away a full can.

  • Absolutely unbelievable expansion!
Style: Gap Filler 25.3oz Size: 2 Pack
Let me just say this… if you are used to the old school spray foam from even a decade ago… this stuff is 25x better and a little goes a LONG way. It’s easy to apply, but do not think this stuff doesn’t expand, because 30 minutes later you will see what it can do! I side this to fill various gaps ranging from 2-8 inches and it works fantastic. I will definitely purchase this again. ... show more
