  • Perfect for sealing cracks and filling gaps
Size: Gaps & Cracks 13.5 oz Number of Items: 1
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

  • Seems effective
Size: Pest Block 13.52 oz Number of Items: 12
Any spray foam is going to be messy but this performed as well as any of the spray foam barriers that I have used. It does smell like moth balls, so I would only use it for exterior purposes. One can seems to go a lot further than other well known brands.

About the same as Great Stuff for large holes, but more for the money. It's a much bigger bottle. I'll be buying more.

  • Worked great 1st time
Size: Gap Filler 25.3 oz Number of Items: 2
After the first use it was hard to dispense it again. Air would come out of the Canister but the foam seemed to stay. After shaking it several times and turning it upside-down, I was able to get it to work better but still nothing like the 1st use.

  • Perfect

I didn't get to use it right away so once everything was ready this sealant was used in more than 10 suspected holes. Haven't seen any mice for a couple of weeks now.

  • Defective product
4 of the 12 cans sent are defective, and will not release any foam whatsoever. But Amazon would not replace the item due to the order being at the end of august. I was waiting for my new building construction to be completed. So basically there saying. You just use all 12 cans within 30 days to have any type of warranty replacement. In the past 5 years I’ve spent over $25,000 with Amazon. So they are losing a loyal customer over a $40 product warranty ... show more
