Customer Questions & Answers

  • Question: What is Flex Seal Liquid used for?

    Answer: Flex Seal Liquid is a versatile liquid rubber coating suitable for a wide range of applications. It's primarily used to seal leaks and protect surfaces, making it ideal for roofs, basements, RVs, and campers. The liquid forms a flexible, waterproof barrier that adheres to various materials, effectively preventing moisture penetration. By applying Flex Seal Liquid, you can protect your belongings from water damage, prolong the life of outdoor gear, and enhance the durability of surfaces exposed to harsh elements.
  • Question: How do you apply Flex Seal Liquid?

    Answer: Applying Flex Seal Liquid is straightforward. First, clean the surface you wish to treat to remove dirt, grease, and other contaminants. Shake the container well, then pour the liquid onto the designated area or use a brush for precise applications. It's recommended to apply it in thin layers, allowing each layer to dry thoroughly before adding more. This method ensures optimal adhesion and results in a smooth finish. Many users find that using a roller or brush works best for large areas, such as roofs.
  • Question: Is Flex Seal Liquid safe to use indoors?

    Answer: Yes, Flex Seal Liquid can be used indoors, but it is important to ensure proper ventilation during application. The product contains solvents that can release fumes, so wearing a mask and working in a well-ventilated area is advisable. The waterproof and flexible nature of the sealant also makes it suitable for sealing cracks and leaks in basements or bathrooms, offering protection against moisture without compromising indoor air quality when proper precautions are taken.
  • Question: How long does Flex Seal Liquid take to dry?

    Answer: Flex Seal Liquid typically takes 24 to 48 hours to fully cure, depending on humidity and temperature conditions. While the surface may become tack-free in just a few hours, allowing adequate drying time is essential to achieve maximum durability and flexibility. For outdoor applications, consider weather conditions, as rainy or humid conditions may extend the drying timeframe. If you apply multiple layers, ensure the previous layer is fully dry before applying the next for optimal results.
  • Question: Can Flex Seal Liquid be painted over?

    Answer: Yes, Flex Seal Liquid can be painted over once it is completely cured. Using an oil-based or water-based paint will work well, but ensure that the paint is compatible with rubber coatings. This allows you to customize the finish while still benefiting from the waterproof seal. Many users choose to paint over Flex Seal for aesthetic purposes on RVs or outdoor furniture, thereby enhancing their visual appeal without sacrificing protective qualities.
  • Question: What materials does Flex Seal Liquid adhere to?

    Answer: Flex Seal Liquid adheres well to various surfaces, including metal, wood, glass, concrete, and plastic. This versatility makes it an excellent choice for multiple repair scenarios, such as fixing leaks in gutters or sealing up RV roofs and camper exteriors. Users have found it particularly effective in both indoor and outdoor applications, providing a durable and flexible barrier against water damage and wear over time.
  • Question: Is Flex Seal Liquid UV resistant?

    Answer: Yes, Flex Seal Liquid is UV resistant, making it suitable for outdoor use without fading or cracking under sun exposure. This feature is particularly beneficial for applications on roofs and outdoor structures. Users often appreciate this quality when using the product for RV or camper repairs, as it helps maintain the integrity and appearance of surfaces in harsh weather conditions, extending the lifespan of their outdoor gear.
  • Question: Can I use Flex Seal Liquid on a wet surface?

    Answer: Flex Seal Liquid works best on clean, dry surfaces for optimal adhesion. Applying it on a wet surface may reduce its effectiveness and ability to create a solid seal. If you're dealing with leaks, it's advisable to dry the area first, if possible. For emergencies, however, some users have reported success in applying the sealant to damp surfaces, but keep in mind that this may lead to less effective sealing over time.
  • Question: How should I store Flex Seal Liquid?

    Answer: Flex Seal Liquid should be stored in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the cap is tightly sealed to prevent the liquid from drying out or becoming contaminated. Proper storage extends the life of the product and maintains its performance qualities. Keeping it in a climate-controlled area, such as a garage or shed, is often recommended, especially if it will not be used frequently.
