Flex adhesive and sealants

Flex Seal, widely known for its flagship liquid rubber coating, was founded by brothers Phil and Alan Swift. The brand quickly rose to international fame through its iconic 'infomercial' marketing style, demonstrating the extreme durability and waterproof nature of its products. Based in the United States, Flex Seal products are primarily manufactured domestically to ensure quality control across their expanding product line, which now includes tapes, glues, and flood protection solutions.

The brand remains under the private ownership of its original founding entity, Swift Response, LLC. Unlike many household brands that eventually get acquired by global conglomerates, Flex Seal has maintained a direct line of ownership from the original inventors, headquartered in Weston, Florida. This allows the company to maintain its unique branding and focus on high-performance sealants for both professional and DIY consumer markets worldwide.
