What Stands Out
Waterproof Sealant
Flex Seal Liquid provides a robust waterproof barrier, effectively sealing leaks in roofs, basements, and even marine applications, ensuring long-lasting protection against moisture and damaging leaks.
Flexible Coating
This liquid rubber coating remains flexible, accommodating natural movements in surfaces like RVs and trailers without cracking, thus ensuring a durable seal that adapts to various environmental changes.
UV Resistant
Flex Seal's UV resistant formula protects against sun damage, maintaining its integrity and aesthetic appeal over time, making it an ideal choice for both indoor and outdoor applications.

Customer Questions & Answers
-
Question:
What is Flex Seal Liquid used for?
Answer: Flex Seal Liquid is a versatile liquid rubber coating designed to seal and protect a wide range of surfaces. It can be applied to roofs, basements, RVs, and various outdoor equipment to provide waterproofing, flexibility, and UV resistance. This product is ideal for preventing leaks, repairing cracks, and extending the lifespan of surfaces that face harsh environmental conditions. -
Question:
How do you apply Flex Seal Liquid?
Answer: To apply Flex Seal Liquid, ensure the surface is clean and dry. Using a brush, roller, or even a spray gun, coat the area evenly, allowing for sufficient drying time between layers. The liquid rubber forms a protective membrane that seals the surface, making it ideal for projects like roof repairs or protecting outdoor furniture. Ensure proper ventilation while applying for the best results. -
Question:
Is Flex Seal Liquid safe for indoor use?
Answer: Flex Seal Liquid can be used indoors, but ensure proper ventilation during application as it can emit fumes. It is commonly used for sealing indoor leaks in areas like basements. However, it is essential to wait for the product to cure before reoccupying the space to ensure a safe environment. -
Question:
How long does Flex Seal Liquid take to dry?
Answer: Flex Seal Liquid typically dries to the touch within 2 to 3 hours, but full curing can take up to 24 hours depending on humidity and temperature. For optimal results, allowing more time before exposing the coated surface to water or stress is recommended. This drying time is crucial for achieving its full protective properties. -
Question:
Can Flex Seal Liquid be painted over?
Answer: Yes, once fully cured, Flex Seal Liquid can be painted over with latex paint. This provides an opportunity to match the coating with the color scheme of your project. However, it’s advisable to wait a few days after application for the best adhesion and to ensure the sealant has fully set. -
Question:
What surfaces can Flex Seal Liquid be applied to?
Answer: Flex Seal Liquid can be applied to a variety of surfaces, including metal, wood, concrete, plastic, and more. This versatility makes it suitable for numerous applications, whether you’re working on a roof, repairing gutters, or protecting RVs from leaks. Ensure a clean, dry surface for optimal adhesion. -
Question:
Is Flex Seal Liquid resistant to extreme weather conditions?
Answer: Yes, Flex Seal Liquid is designed to withstand extreme weather conditions, including rain, sunlight, and temperature fluctuations. Its UV resistance ensures that it won't degrade over time, making it ideal for outdoor applications such as roof repairs and protecting boats or outdoor gear from the elements. -
Question:
Can you use Flex Seal Liquid on plumbing pipes?
Answer: Flex Seal Liquid can temporarily seal minor leaks on plumbing pipes, but it is not a replacement for the proper plumbing repairs. It's recommended for non-pressurized areas only. Use it as a quick fix while you arrange for professional repairs to ensure long-term effectiveness. -
Question:

Answer: You can purchase Flex Seal Liquid, 1 Gallon, White from Ubuy in Canada. Ubuy offers a wide selection of Flex Seal products, ensuring you receive the right sealant for your needs, with the convenience of ordering online and having it delivered right to your doorstep.
Flex Seal Liquid Sealers Editorial Review
Flex Seal Liquid Rubber is a versatile and effective sealant that can be used for various applications. It can be removed from metal surfaces with the use of mineral spirits, acetone, or a citrus-based cleaner. It is not recommended for use on areas that come into contact with potable water. The coverage ranges from up to 20 sq. ft. for a 16oz can to up to 150 sq. ft. for a gallon can. While it can be used to seal fiberglass shower pans and line raised garden beds, it may not be suitable for painting plastic or painting bathtubs as it may become slippery when wet. Overall, many customers have had success using Flex Seal Liquid for a wide range of applications, but it is important to test it on a small area before full application.
