Customer Questions & Answers

  • Question: What surfaces can I use Flex Seal spray on?

    Answer: Flex Seal spray can be applied to a variety of surfaces including metal, wood, concrete, masonry, fabric, plastic, and rubber. This versatility makes it ideal for both indoor and outdoor projects. It's particularly effective for sealing gaps in roofs or repairing cracks in downspouts, ensuring long-lasting protection from moisture. Consider using it for automotive fixes too, as it adheres well to different materials commonly found in vehicles.
  • Question: How long does Flex Seal take to dry?

    Answer: Flex Seal typically dries to the touch within 2 to 3 hours. However, full curing can take up to 24 to 48 hours, depending on the thickness of the application and environmental conditions. It's wise to let it cure completely for the best results, especially in outdoor settings where exposure to rain can occur. This ensures a robust and effective seal against leaks.
  • Question: Is Flex Seal waterproof?

    Answer: Yes, Flex Seal is a waterproof coating designed to stop leaks effectively. Once applied and dried, it forms a flexible, rubberized barrier that repels water. This feature makes it great for a range of applications including sealing roofing leaks, repairing gutters, or waterproofing outdoor furniture. Users find it particularly useful in areas that experience heavy rainfall or moisture.
  • Question: Can I paint over Flex Seal spray?

    Answer: Yes, you can paint over Flex Seal once it is fully cured. Using exterior-grade paint can enhance the durability of your project and ensure it blends seamlessly with your surroundings. This is especially beneficial when used on roofs or siding where aesthetics matter. Ensure that the Flex Seal is completely dry before applying paint for optimal adhesion.
  • Question: What is the best way to apply Flex Seal spray?

    Answer: For optimal results, clean the surface thoroughly before application. Shake the can well, and apply Flex Seal in a sweeping motion, aiming for a thin, even coat. Multiple light coats are recommended rather than a single heavy coat, allowing each layer to dry before applying the next. This technique ensures comprehensive coverage, especially in areas prone to leaks like pipes or roof seams.
  • Question: Can Flex Seal be used for automotive repairs?

    Answer: Absolutely! Flex Seal is effective for various automotive repairs. It can seal leaks in gas tanks, radiators, and even undercarriage components. Its rubberized nature ensures that it can withstand vibrations and changes in temperature, making it a reliable fix for emergency situations. Just ensure the surface is clean and dry before application for the best results.
  • Question: What temperature is ideal for applying Flex Seal?

    Answer: The ideal temperature range for applying Flex Seal is between 60°F and 100°F. Warmer temperatures promote better adhesion and faster drying times. Colder conditions can impact the effectiveness of the spray, leading to longer cure times. Planning your project on a mild day can enhance the performance and reliability of your application significantly.
  • Question: Is Flex Seal safe for indoor use?

    Answer: Yes, Flex Seal is safe for indoor use, provided that you apply it in a well-ventilated area. The spray may emit fumes during application, so using it near open windows or with a fan can help improve air circulation. It's often used indoors to seal leaks in plumbing or to fix appliances, ensuring you maintain a clean and dry living space.
  • Question: Can I use Flex Seal to seal a leaking roof?

    Answer: Yes, Flex Seal is highly effective for sealing a leaking roof. Its rubberized coating creates a flexible barrier that adapts to movement, ensuring that the leak is sealed completely. For the best results, apply it on clean, dry surfaces and consider using it during dry weather for optimal adhesion. Homeowners often report great success in preventing leaks in shingles or other roofing materials.
  • Question: Where can I buy Flex Seal in Sierra Leone?

    Answer: You can purchase Flex Seal at Ubuy. Ubuy offers a range of Flex Seal products, making it convenient to find exactly what you need for your DIY projects and repairs.
