Customer Questions & Answers

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

    Answer: Flex Seal works on a variety of surfaces, including wood, metal, concrete, and plastic. It's ideal for sealing leaks in gutters, roofs, RVs, and more. The waterproof rubber coating creates a strong, flexible barrier against moisture, ensuring long-lasting protection for your projects. For example, if you have a leaky roof, applying Flex Seal can prevent water from causing further damage.
  • Question: How long does it take for Flex Seal to dry?

    Answer: Flex Seal typically dries to the touch within 2-3 hours, but curing can take up to 24 hours depending on the thickness applied and environmental conditions. It's important to allow the sealant to cure fully before exposing it to water or stress. This ensures a strong, effective bond that keeps leaks at bay. For instance, if applied on a gutter, wait at least 24 hours for the best results before heavy rain.
  • Question: Can Flex Seal be painted over?

    Answer: Yes, Flex Seal can be painted over once fully cured. To achieve the best results, it's recommended to use an oil-based or latex paint. This allows you to match the sealant to your desired color scheme, making it perfect for aesthetic projects around your home or RV. For example, if you've used Flex Seal on your camper, you can paint it to blend seamlessly with the rest of your vehicle.
  • Question: Is Flex Seal safe to use indoors?

    Answer: Flex Seal may be used indoors, but it’s crucial to ensure proper ventilation during application due to the strong odor associated with the product. While it is safe once dried, adequate airflow helps dissipate fumes quickly. Use it for indoor projects like repairing leaks in a bathroom or kitchen sink if necessary. Just make sure to let it cure completely before closing off the area.
  • Question: Can I use Flex Seal on wet surfaces?

    Answer: Flex Seal is designed to adhere to both dry and wet surfaces, making it versatile for quick fixes. However, achieving the best seal is easier on dry materials. If you're dealing with an urgent leak, it can still provide a temporary solution even when applied on damp areas. A common scenario is using it to seal a leaky garden hose or a dripping gutter during rainy conditions.
  • Question: Will Flex Seal work on running water?

    Answer: Flex Seal is not designed for use under running water; however, it can be applied on wet surfaces to temporarily stop leaks. After application, give the sealant time to set and create a waterproof barrier. This functionality is helpful for urgent situations, such as when you need to quickly seal a plumbing leak before a repair can be made.
  • Question: How do I properly apply Flex Seal?

    Answer: To apply Flex Seal, shake the can well before use, and hold it approximately 10-12 inches away from the surface. Apply in a sweeping motion to ensure an even coat. Multiple layers may be necessary for optimal sealing, allowing each coat to dry before applying the next. This technique is effective for larger projects like roofs, where multiple applications can enhance durability and leak resistance.
  • Question: Can Flex Seal be used for automotive applications?

    Answer: Yes, Flex Seal can be utilized for automotive repairs such as sealing leaks in hoses, radiators, and even undercarriage coating. Its waterproof and flexible qualities make it suitable for handling the demands typically faced by automotive parts. For instance, if your RV has a leaky water tank, Flex Seal could provide a robust temporary fix until a more permanent solution is applied.
  • Question: How do I remove Flex Seal if needed?

    Answer: To remove Flex Seal, you can use a utility knife to carefully cut away the bulk of the sealant, followed by using mineral spirits to dissolve any residual product. Always test a small area first to avoid damaging the underlying surface. This is particularly useful for projects where you need to replace or repair old seals without damaging the materials underneath.
  • Question: Where can I buy Flex Seal in The Bahamas?

    Answer: You can buy Flex Seal, 14 oz, White at Ubuy in The Bahamas. Ubuy offers a convenient online shopping experience, ensuring you can easily locate this essential waterproof sealant for your projects.

Flex Seal Sealers Editorial Review

Flex Seal appears to be a versatile product that can be used on a variety of surfaces including PVC pipes, concrete, plastic, metal, fabric, vinyl, and rubber. However, customers have had mixed experiences with the product. While some have found it easy to apply and water-resistant, others have complained about the product being clumpy or not drying fast enough. Additionally, some customers have found that it doesn't work well on certain surfaces or issues such as sealing small cracks or leaks. Overall, it seems that Flex Seal may work well for some applications, but it's important to test it on a small area first and be aware of its limitations.
