Why Great Stuff Pestblock vs Regular Is Necessary
From my experience, choosing Great Stuff Pestblock over regular foam is a game-changer when it comes to keeping pests out of my home. Regular foam might fill gaps and cracks, but it doesn’t have the added benefit of pest-repelling ingredients. I noticed that with regular foam, small insects and rodents could still find their way through or around the seal. Great Stuff Pestblock, on the other hand, not only seals these entry points but actively deters pests, giving me peace of mind.
Another reason I find Great Stuff Pestblock necessary is its durability. Over time, regular foam can shrink or deteriorate, creating new openings for pests. Pestblock foam remains firm and intact for longer periods, meaning fewer repairs and less worry about unwanted visitors. For me, investing a little more upfront has saved time and hassle down the road, making it a smart choice for anyone serious about pest control.
My Buying Guides on Great Stuff Pestblock Vs Regular
When I was looking for a foam sealant to tackle some gaps and cracks around my home, I came across two popular options from Great Stuff: Pestblock and Regular. After trying both, I wanted to share my experience and help you decide which one might be right for your needs.
What Is Great Stuff Regular?
Great Stuff Regular is the classic expanding foam sealant I first used for general sealing and insulating tasks. It’s designed to fill gaps, cracks, and holes to prevent air leaks and improve energy efficiency. I liked that it expands quickly and hardens into a durable foam that can be trimmed or painted over.
What Is Great Stuff Pestblock?
Great Stuff Pestblock is a newer formula that claims to do everything the Regular version does but with added pest-repelling properties. It’s designed not only to seal gaps but also to help keep bugs and rodents from entering through those openings. Since pests were a concern in my area, I decided to give this one a try.
Key Differences I Noticed
- Pest Protection: The biggest difference is the Pestblock’s added insect and pest deterrent. While Regular just seals, Pestblock includes ingredients meant to repel pests. After using Pestblock, I noticed fewer spiders and ants near the sealed areas compared to when I used Regular.
- Expansion and Texture: Both foams expand similarly, but Pestblock felt slightly denser once cured. It still trimmed easily but seemed a bit tougher.
- Application: I used the same applicator straw for both, and the spray pattern and ease of use were nearly identical.
- Price: Pestblock is a bit more expensive than Regular, which makes sense given the additional pest-control feature.
When Should You Use Great Stuff Regular?
If your main goal is just to block drafts, seal air leaks, or fill insulation gaps, Great Stuff Regular works perfectly. It’s especially ideal if pests aren’t a big problem where you live, or if you plan to use other pest control methods. I found it great for general weatherproofing around windows, doors, and plumbing penetrations.
When Should You Choose Great Stuff Pestblock?
If you’re dealing with frequent pest issues—like insects or small rodents trying to get inside through cracks—Pestblock is worth considering. I used it around foundation cracks, attic vents, and basement gaps where pests tend to enter. The extra peace of mind knowing it might deter bugs made it worth the extra cost for me.
My Tips for Using Both Products
- Wear gloves and work in a well-ventilated area since the foam can be sticky and has strong fumes.
- Don’t overfill gaps; the foam expands a lot and can spill out.
- Trim and shape the foam after it cures for a clean finish.
- Consider painting over the foam if it will be exposed to sunlight, as UV rays can degrade it over time.
Final Thoughts
Both Great Stuff Regular and Pestblock are excellent expanding foams that seal gaps effectively. My choice depends on whether pest control is a priority. For everyday sealing, Regular does the job well and is budget-friendly. But if you want that added defense against unwanted critters, Pestblock is a smart upgrade. Hopefully, my experience helps you pick the right foam for your project!
