My Buying Guides on Great Stuff Pestblock Reviews
When I first started looking for an effective solution to keep pests out of my home, I came across Great Stuff Pestblock. After trying it myself and researching extensively, I want to share my experience and insights to help you decide if this product is right for you. Here’s everything I learned during my search and use of Great Stuff Pestblock.
What Is Great Stuff Pestblock?
Great Stuff Pestblock is a polyurethane foam sealant designed specifically to block pests like rodents, insects, and other unwanted critters from entering your home. Unlike regular expanding foam, it contains a pest-repellent ingredient that discourages pests from chewing or nesting in the sealed areas.
Why I Chose Great Stuff Pestblock
I was dealing with small gaps around my windows, doors, and attic vents where I noticed signs of mice and insects. I wanted a product that not only sealed these gaps but also helped keep pests away long-term. Great Stuff Pestblock appealed to me because of its dual action — it fills gaps tightly and includes pest deterrents.
Key Features I Noticed
- Easy Application: The foam comes in a convenient spray can with an applicator straw, making it simple to target cracks and crevices.
- Effective Seal: It expands to fill gaps but hardens quickly to form a durable barrier.
- Pest-Repellent Formula: Contains ingredients that pests dislike, which adds a layer of protection beyond just sealing.
- Versatile Use: I used it indoors and outdoors — around plumbing, vents, and foundation cracks.
- Paintable and Sandable: Once cured, it can be trimmed, sanded, or painted to blend with the surrounding surface.
What I Liked About Great Stuff Pestblock
- It significantly reduced the number of pest intrusions after application.
- The foam was easy to control and didn’t create a mess when used carefully.
- The seal felt solid and durable; I felt confident it would last through different weather conditions.
- It saved me money and hassle compared to hiring professional pest control immediately.
Things to Keep in Mind Before Buying
- Curing Time: It takes several hours to fully cure, so avoid touching or disturbing the foam during this period.
- Not a Complete Pest Solution: While it helps block entry points, it won’t eliminate pests already inside your home — additional pest control measures may be necessary.
- Proper Ventilation: Use in well-ventilated areas because of the strong chemical smell during application.
- Protective Gear Recommended: Wearing gloves and eye protection is a good idea to prevent irritation.
How to Use Great Stuff Pestblock for Best Results
- Clean the area around the gap or crack to ensure good adhesion.
- Shake the can well before use.
- Insert the applicator straw into the gap and slowly dispense foam, filling about half the cavity as the foam will expand.
- Allow it to cure undisturbed for at least 8 hours.
- Trim excess foam and paint if desired for aesthetics.
Final Thoughts From My Experience
Great Stuff Pestblock worked well for me as a preventative step to keep pests out of my home. It’s a practical, affordable solution if you have minor gaps and holes that serve as entry points. Remember, it’s best used as part of a comprehensive pest control approach, including cleanliness and monitoring. If you’re looking for an easy-to-use foam sealant with added pest deterrent benefits, I’d recommend giving Great Stuff Pestblock a try based on my experience.
