Customer Questions & Answers

  • Question: What is Flex Seal Liquid and how is it used?

    Answer: Flex Seal Liquid is a versatile, liquid rubber sealant that can be used to coat, seal, and protect various surfaces. It's designed for numerous applications, such as sealing leaks in roofs, gutters, and pipes, as well as waterproofing wood, metal, and concrete surfaces. After application, it forms a flexible, rubbery coating that withstands harsh weather conditions and prevents corrosion. Whether you’re repairing a cracked bird bath or sealing a leaky basement, Flex Seal Liquid provides an efficient and durable solution.
  • Question: Is Flex Seal Liquid safe to use indoors?

    Answer: Yes, Flex Seal Liquid can be used indoors as long as there is adequate ventilation. The product has a low odor, making it more suitable for indoor applications compared to other sealants. It is perfect for indoor repair projects, such as sealing leaks in pipes or cracks in walls. Just ensure your workspace is well-ventilated and avoid using it near open flames, as it contains solvents. This makes it ideal for home repairs where air quality is a priority.
  • Question: How long does it take for Flex Seal Liquid to dry?

    Answer: Flex Seal Liquid typically takes about 24 to 48 hours to fully cure, depending on environmental conditions such as temperature and humidity. While it may feel tacky to the touch within an hour, allowing it to dry completely is crucial for optimal performance. This extended drying time enables it to form a robust bond with the surface, offering long-term protection against moisture damage and leaks. For best results, plan your project accordingly and avoid applying during damp or cool conditions.
  • Question: Can Flex Seal Liquid be painted over?

    Answer: Yes, once Flex Seal Liquid is fully cured, it can be painted over with most types of paint. This allows you to customize the appearance of your project while enjoying the protective benefits of Flex Seal. For the best results, make sure the surface is clean and dust-free before painting. This can be particularly useful for outdoor furniture, planters, or any treated surfaces where aesthetics are important while maintaining waterproofing.
  • Question: What surfaces can I use Flex Seal Liquid on?

    Answer: Flex Seal Liquid is highly versatile and can be applied on a wide range of surfaces including wood, metal, concrete, and masonry. It adheres well, creating a waterproof seal that protects against moisture. This versatility makes it ideal for various applications from home repairs to outdoor projects, such as sealing a cracked patio or protecting exposed metal from rust. Its adaptability ensures that almost any material can benefit from its sealing properties.
  • Question: How do I apply Flex Seal Liquid?

    Answer: To apply Flex Seal Liquid, start by ensuring the surface is clean and dry. You can use a brush, roller, or pour it directly from the container, depending on the area you are sealing. Apply evenly, ensuring complete coverage of the area. Multiple coats may be necessary for thorough sealing and protection. It’s practical for users to work on small sections at a time, especially for bigger projects, providing optimal results without overwhelming the task.
  • Question: Is Flex Seal Liquid environmentally friendly?

    Answer: Flex Seal Liquid is designed with user safety in mind but is not classified as environmentally friendly due to the presence of certain chemicals. It’s advisable to follow application guidelines and safety precautions to minimize impact. The product’s ability to prolong the lifespan of materials can lead to less waste over time. For users concerned about eco-friendliness, consider using it judiciously on repairs that keep materials out of landfills longer.
  • Question: Can Flex Seal Liquid be used on roofs?

    Answer: Yes, Flex Seal Liquid is effective for repairing roofs, particularly flat or sloped roofs where leaks often occur. It can seal cracks and holes, forming a watertight barrier that prevents further damage. Users find it beneficial for quick repairs during rainy seasons when immediate action is required. Its waterproof properties help protect roofing materials from deterioration, extending their lifespan and maintaining the integrity of your home.
  • Question: What should I do if I get Flex Seal Liquid on my skin?

    Answer: If you get Flex Seal Liquid on your skin, immediately wash the affected area with soap and warm water. Using a solvent like mineral spirits can also help remove it, but be cautious and read all safety instructions on the label. It’s important to wear gloves and protective gear during application to prevent skin contact in the first place. Ensuring safety while using the product will minimize any issues and allow for worry-free use.
