Customer Questions & Answers

  • Question: What is GREAT STUFF PRO Gaps and Cracks Fireblock Foam Insulation Sealant?

    Answer: GREAT STUFF PRO Gaps and Cracks is a closed cell, polyurethane expanding spray foam insulation sealant designed to fill gaps and cracks around your home. This 30oz can is specifically formulated for fireblock applications, making it ideal for areas where fire safety is a concern. It's effective for sealing around windows, doors, and other penetrations, preventing air leaks and improving energy efficiency. Use it in both residential and commercial projects to maintain a comfortable indoor environment.
  • Question: How does the polyurethane expanding foam work?

    Answer: The polyurethane expanding foam works by expanding upon application to fill voids, gaps, and cracks. As it cures, it forms a durable, airtight seal that can help reduce energy loss and prevent drafts. This foam adheres well to various surfaces, including wood, metal, and concrete, making it versatile for multiple applications. For best results, ensure the surfaces are clean and dry before applying. This sealant is particularly useful where traditional caulks and sealants may not suffice.
  • Question: Is GREAT STUFF PRO safe to use indoors?

    Answer: Yes, GREAT STUFF PRO is safe for indoor use once fully cured. While applying the foam, it's important to wear protective gear such as gloves and a mask due to fumes. The cured foam is non-toxic and does not release harmful particles, making it suitable for sealing indoor air leaks. Always ensure proper ventilation during application for occupant safety and comfort. It’s commonly used for sealing areas around plumbing, electrical outlets, and HVAC systems.
  • Question: What kind of surfaces can GREAT STUFF PRO be applied to?

    Answer: GREAT STUFF PRO is designed to adhere well to a variety of surfaces, including wood, metal, masonry, and drywall. Its versatility makes it an excellent choice for sealing both interior and exterior gaps, such as around baseboards, in attics, or at rooflines. Before application, ensure that surfaces are clean and free of dust or debris to maximize adhesion. This makes it an ideal solution for a range of home improvement tasks, especially in DIY projects.
  • Question: How long does it take for GREAT STUFF PRO to cure?

    Answer: GREAT STUFF PRO typically becomes tack-free within 10-15 minutes after application, but full curing may take up to 8 hours depending on temperature and humidity. The foam expands and hardens to create a solid seal during this time. It’s advisable to avoid disturbing the foam while it cures to ensure optimal performance. Understanding curing time is essential for planning home improvement projects effectively, especially when sealing areas that require further construction or finishing.
  • Question: Can GREAT STUFF PRO be used in exterior applications?

    Answer: Absolutely! GREAT STUFF PRO can be successfully used for exterior applications as it is designed to withstand weathering and outdoor conditions. It is perfect for sealing gaps around windows, doors, and siding to improve energy efficiency and prevent moisture ingress. Proper application can lead to long-lasting results, helping to enhance the exterior integrity of your home. Ensure that the surface is clean and the conditions are suitable for application to achieve the best results.
  • Question: How do you properly apply GREAT STUFF PRO foam?

    Answer: To apply GREAT STUFF PRO foam, start by shaking the canister vigorously for about 30 seconds. Attach the provided nozzle, and for precise application, hold the can upside down, aiming to fill gaps about halfway to allow for expansion. Always wear appropriate protective gear and ensure good ventilation. After application, clean any excess foam immediately with acetone or designated foam cleaner. Following these steps will ensure a smooth, effective application.
  • Question: How many cans are included in a pack of GREAT STUFF PRO?

    Answer: A pack of GREAT STUFF PRO Gaps and Cracks includes 12 cans, each containing 30oz of foam insulation sealant. This bulk packaging is ideal for larger projects or for professionals who need to seal multiple areas efficiently. Having multiple cans on hand ensures that you can tackle various tasks without running out, making it a cost-effective choice for both homeowners and contractors alike.
  • Question: What precautions should I take when using GREAT STUFF PRO?

    Answer: When using GREAT STUFF PRO, always work in a well-ventilated area and wear protective gear, including gloves, goggles, and a mask. Ensure that the area to be sealed is clean and dry for better adhesion. Avoid inhaling vapors during application, and refrain from using the foam near open flames or sparks due to its flammable properties. Following these safety tips ensures a safe working environment while achieving optimal results.
