You’ve walked around your house and spotted those annoying gaps. They are around pipes, windows, foundations, or even in the garage. You already know how quickly they can lead to drafts, moisture, and even pests sneaking in. That’s exactly why I wanted to test out the Red Devil 0909 Spray Foam. It is a triple‑expanding foam designed specifically for sealing large gaps and cracks. And let me tell you, this little can packs a punch.

What I love right away is how simple it is to use. You shake the can, attach the straw, and the foam comes out smoothly without the messy sputtering some other brands have. It expands quickly, so you don’t need to overfill the space—just a little goes a long way. Within minutes, you can see it rising and filling every nook and cranny. Once it cures, it forms a strong, airtight, waterproof seal that instantly makes your home feel more protected.

One of the biggest perks is how versatile it is. You can use it indoors or outdoors, and once it’s fully cured, you can cut it, sand it, and paint it to match the surrounding area. That means no weird yellow foam sticking out forever. It blends right in once you finish it off. For busy families, DIY beginners, or anyone who just wants a quick fix without calling a handyman, this is the kind of product that makes you feel capable and accomplished.

I also appreciate that it helps with more than just drafts. If you’ve ever had tiny critters find their way into your basement or crawl space, sealing those larger gaps is one of the easiest ways to stop them. The foam expands enough to block those entry points, and once it hardens, it’s tough for pests to chew through. It’s a simple step that makes a big difference.

The curing time is pretty fast, and the final result is firm and durable. I tested it around a pipe opening in the basement and along a window frame where cold air always sneaks in. Both areas sealed beautifully, and the foam stayed exactly where I wanted it. No sagging, no shrinking, no cracking. Just a clean, solid seal.
