Customer Questions & Answers
-
Question:
What is Flex Seal Spray and how does it work?
Answer: Flex Seal Spray is a waterproof rubberized coating that can be used to seal various surfaces against moisture and flooding. Its unique formula allows it to adhere to a wide variety of materials, making it ideal for door tracks, seams, sills, and small openings. Once applied, it creates a durable barrier that prevents water from seeping through. For instance, if you have gaps in your window sills, applying Flex Seal can help protect your interiors from water damage during heavy rain. -
Question:
What surfaces can I apply Flex Seal Spray on?
Answer: Flex Seal Spray can be used on multiple surfaces including metal, wood, glass, plastic, and concrete. This versatility makes it suitable for a range of projects, whether you are sealing leaking gutters, repairing a roof or protecting tools stored outdoors. When applying the spray, ensure the surface is clean and dry for optimal adhesion. For example, if you’re working on your bathroom, it can help seal small cracks where water might leak in. -
Question:
Is Flex Seal Spray removable after application?
Answer: Yes, Flex Seal Spray can be removed after application, which is a key feature of the product. While it creates a strong bond, it can be peeled away or scraped off the surface without damaging it. This is particularly useful if you ever need to make repairs or changes. For instance, if you used it to patch a crack, but then decide to tile over that area later, you can easily remove the Flex Seal before starting your new project. -
Question:
How long does it take for Flex Seal Spray to dry?
Answer: Flex Seal Spray typically requires 24 to 48 hours to fully cure, depending on conditions such as humidity and temperature. While it may feel dry to the touch within a few hours, allowing more time ensures that the coating has bonded properly to the surface for optimal performance. For example, if you seal a crack in your basement, waiting a full day ensures complete waterproofing before exposing it to heavy rain. -
Question:
Can Flex Seal Spray be used indoors?
Answer: Absolutely! Flex Seal Spray is suitable for indoor use as well. It's ideal for fixing minor leaks and sealing drafts that may cause water damage. Areas like kitchens, bathrooms, and basements can benefit greatly from its application. Just ensure that the area is well-ventilated during use. For example, if your kitchen has a small leak under the sink, applying Flex Seal can prevent damage to cabinetry. -
Question:
What makes Flex Seal Spray effective against flooding?
Answer: Flex Seal Spray is designed with a super strong, flexible, and waterproof formula that makes it highly effective against flooding. Its ability to penetrate and seal small gaps helps create a protective barrier that prevents water intrusion during storms. For example, you can use it to seal door tracks which are often prone to leaks, ensuring your home remains dry during heavy rainfall. -
Question:
How much coverage can I expect from a 10 oz can of Flex Seal Spray?
Answer: A 10 oz can of Flex Seal Spray typically covers about 12 to 16 square feet in a single coat. This makes it sufficient for small repairs or projects. For larger jobs, you may need to purchase multiple cans. Keep in mind that for optimal results, a thicker coat is recommended, especially on porous surfaces. For example, you can use it to cover multiple seams on outdoor furniture to help prolong its life. -
Question:
Can I paint over Flex Seal Spray?
Answer: Yes, once Fully cured, you can paint over Flex Seal Spray if desired. This feature allows it to seamlessly integrate into your home's aesthetics. However, it’s recommended to let the coating cure completely before applying any paint. For example, if you used Flex Seal to waterproof a basement, you can paint over it later to match your decor after the necessary drying time. -
Question:
Is Flex Seal Spray safe for pets and children?
Answer: Flex Seal Spray, once fully cured, is generally considered safe for use around pets and children. However, it's important to keep them away during application and until the product is completely dry. The product is non-toxic, but it is advised to follow safety guidelines during application. For instance, sealing areas in your home before children or pets access them can help ensure their safety afterward. -

Ubuy provides convenient access to Flex Seal's robust waterproofing solutions for your home improvement projects, delivering them directly to your doorstep.

FlexSeal Sealers Editorial Review
I was skeptical at first, but this product exceeded my expectations. I used it to seal a leak in my roof and it worked like a charm. It also held up well during a heavy rainstorm. The spray is easy to use and the coverage is good. It does take some time to dry completely, but once it sets, it creates a strong, waterproof seal. I will definitely be using this product for future projects.
