Customer Questions & Answers
-
Question:
What is Flex Seal Liquid, and how does it work?
Answer: Flex Seal Liquid is a rubber coating sealant designed to create a waterproof barrier on various surfaces. It works through a unique formula that seeps into cracks and holes, expanding to fill gaps, and then dries to form a flexible, breathable coating. This flexibility allows it to handle minor movements in the materials it covers, making it ideal for different applications such as roof repair, and sealing basements or RVs. -
Question:
Is Flex Seal Liquid suitable for outdoor projects?
Answer: Yes, Flex Seal Liquid is highly suitable for outdoor projects as it is UV resistant and can withstand adverse weather conditions. This makes it perfect for covering areas exposed to sunlight, rain, and wind, such as roofs, campers, and trailers. Its durable nature ensures long-lasting protection against the elements, allowing you to confidently tackle outdoor repairs. -
Question:
Can I use Flex Seal Liquid on wet surfaces?
Answer: Flex Seal Liquid should ideally be applied to dry surfaces for optimum adhesion. However, it can be used in damp conditions if necessary but may not perform as effectively as on completely dry surfaces. For best results, ensure that the area is clean and dry before application to maximize the sealant's effectiveness in waterproofing and protecting the repair. -
Question:
How long does it take for Flex Seal Liquid to dry?
Answer: Flex Seal Liquid typically dries to the touch in about 2 to 3 hours, but to achieve full curing and maximum durability, it is advisable to wait 24 to 48 hours. Factors like humidity and temperature can influence drying times, so ensuring optimal conditions can speed up the process. For projects requiring full waterproofing, allowing adequate drying time is essential. -
Question:
Can Flex Seal Liquid be painted over?
Answer: Yes, Flex Seal Liquid can be painted over after it has completely dried. This feature allows for aesthetic customization, blending the sealed area with its surroundings. When painting over, use high-quality vinyl or latex exterior paints to ensure good adhesion, and always do a patch test first to confirm compatibility. This is particularly useful for projects where aesthetics matter, like RVs and campers. -
Question:
What surfaces can Flex Seal Liquid be used on?
Answer: Flex Seal Liquid can be applied to a wide variety of surfaces including metal, wood, rubber, plastic, and concrete. This versatility makes it an excellent choice for different projects such as sealing cracks in concrete driveways, fixing metal roofs, or waterproofing wooden surfaces in basements. Make sure the surface is clean and properly prepped for the best results. -
Question:
Is Flex Seal Liquid safe for indoor use?
Answer: Yes, Flex Seal Liquid is safe for use indoors as long as proper ventilation is ensured during application. Its non-toxic formulation allows it to be used in areas needing sealing, such as basements and indoor repairs, without harmful side effects. Always ventilate the area to disperse fumes for a healthier atmosphere while working with the product. -
Question:
What makes Flex Seal Liquid different from other sealants?
Answer: Flex Seal Liquid stands out due to its unique formulation that creates a thick, rubberized coating which is flexible, waterproof, and UV resistant. Unlike traditional sealants that may crack or lose effectiveness over time, Flex Seal remains pliable, making it suitable for various applications. Its use on unconventional surfaces like RV exteriors and marine crafts also sets it apart from standard sealants. -
Question:
Can Flex Seal Liquid fix roof leaks?
Answer: Absolutely, Flex Seal Liquid is highly effective for fixing roof leaks. Its ability to seep into cracks and form a waterproof seal makes it ideal for roofing applications.
