## Description

Expands to fill gaps, cracks, and voids, creating an airtight, moisture-resistant seal that improves energy efficiency and prevents drafts.

Review: Good stuff! - Wow this stuff really expands. I needed to fill in the open space in the AC wall unit in my living room. My advice is to take your time, apply sparingly and let it expand. We rinsed out the straw immediately to ensure we would be able to reuse it.
Review: Just a couple things to keep in mind - This is my go to for insulation and gap filling. Once cured, it's perfect. Just two things to keep in mind: 1. Don't get it on anything you want untouched by foam. It's tenacious and sticky, and getting it off your skin is a chore. Wear gloves. 2. Once you start using a can of it, use as much as possible, because using it again after the foam dries in the tube is pretty much impossible.

## Questions & Answers

**Q: What is the R-rating on this?**
A: Hi Dave! 
The initial R-value is 4.3 per inch and the aged R-value is 3.7. Good luck with your project!

**Q: Is closed or open cell foam?**
A: Hi Meggi, 
This is a closed cell foam.

**Q: can this be used to fill holes between dry wall and hardwood, then covered with molding? Will the foam crack if a nail goes into it?**
A: This is the perfect place to use this foam! I did this in my own home recently when we were installing new baseboard. You can apply the foam in the gap, and like others said be careful about overfilling because it does expand quite a lot. I also highly recommend buying our Cleaner / Amazon # B0002YWRG4  because you can spray this on a paper towel and clean up foam when it's still wet. It's a useful product for any project using GREAT STUFF foams. Don't worry if it puffs out too much, you can cut, sand, caulk or paint this foam once fully cured/dry. The foam will not crack if you nail through it but it also is not structural so you'll need to make sure you're nailing the molding into the wall. Good luck with your project!

**Q: is it safe around a hot baseboard heater pipe coming into the room through the floor?? thats where mice get into the rooms from under the floor**
A: I looked at the can and it doesn't really say. The stuff before it cures is full of flammable gas but it doesn't say anything about keeping the cured material from heat. Now, that being said, (I'm putting on my professional chemist hat) Great Stuff is a polyurethane. And polyurethanes are flammable. So, I would be concerned if the area got very hot, say over 150F. Hope this helps.

### ⭐⭐⭐⭐⭐ Got a gap fill your crack
*by J***H on 4 December 2025*

The only thing I don't like about this stuff is if you just need a little bit and then you store it away you can't use it once that stuff hardens up in the spray nozzle so what I did this time was I made sure to clean out the excess material out of the nozzle in the can itself as well as the straw with an air gun hopefully that preserves it for the next time I need it since this is a massive can
